The correct option is (b) i.e. The area of the remaining figure is 136 in².
What is Right angled triangle?
A right angled triangle, also known as a right triangle, is a triangle in which one of the interior angles measures 90 degrees (a right angle). The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs or the adjacent and opposite sides. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the sum of the squares of the two legs is equal to the square of the hypotenuse.
Given : length = 20 and breadth = 8
The area of given rectangle = l × b
= 20 × 8
= 160 in²
Similarly, area of right angled triangle = 1/2 × b × h
= 1/2 × (20-8) × 4
= 1/2 × 12 × 4
= 24 in²

6. One hundred twenty-five townspeople were interviewed at random. Forty of the interviewed townspeople were from the middle school. The middle school has 800 students. Estimate the size of the town.
Answer:
See below, please.
Step-by-step explanation:
To estimate the size of the town, we can use a proportion.
Number of middle school students / Total town population = Number of interviewed middle schoolers / Total number of interviewed townspeople
Let x be the total town population. Then we have:
800 / x = 40 / 125
Simplifying this proportion, we get:
40x = 800×125
40x = 100000
x = 100000 / 40
x = 2500
Therefore, the estimated size of the town is 2500.Alex used his grandmother’s recipe to make 11 3/7 pounds of granola. If he fills as many bags as he can with 2 2/3 pounds of granola in each bag, how many pounds will he have left over?
A 16/21 pound
B 2 20/21 pounds
C 4 2/7 pounds
D 8 16/21 pounds
The number of pounds that he will have left over from 11 3/7 pounds is 4 2/7
How many pounds will he have left over?To find out how many bags of granola Alex can fill, we need to divide the total amount of granola he made by the amount of granola in each bag.
We can convert 11 3/7 pounds to an improper fraction:
11 3/7 pounds = 80/7 pounds
Also, we have
2 2/3 pounds = 8/3 pounds
Now we can divide the total amount of granola by the amount in each bag:
(80/7) ÷ (8/3)
To divide fractions, we invert the second fraction (change it to its reciprocal) and multiply:
(80/7) × (3/8)
Simplifying, we get:
(80 x 3) / (7 x 8) = 30/7
Divide
(80 x 3) / (7 x 8) = 4 2/7
Hence, the bags is 4 2/7

How much will a new TV be worth now if it depreciates by 9% each month, and you bought it new 8 months ago for $2740?
Give your answer to two decimal places.
How much it's worth after 8 months =$
Answer:
To find out how much the TV is worth now, we need to apply the depreciation rate of 9% to the original price for 8 months:
First, let's calculate the value after the first month:
Value after 1 month = $2740 - (9% of $2740) = $2501.40
Now, let's calculate the value after 2 months:
Value after 2 months = $2501.40 - (9% of $2501.40) = $2275.80
We can continue this process for 8 months to find the current value:
Value after 3 months = $2071.67
Value after 4 months = $1888.81
Value after 5 months = $1725.10
Value after 6 months = $1579.92
Value after 7 months = $1452.16
Value after 8 months = $1339.53
Therefore, the TV is worth $1,339.53 now.
Korey and I have been working with a financial planner named Stephen for years. He's been so good to us in explaining things like retirement, high yield savings, life insurance and college planning. This last time that we met with Stephen he explained to us that our money for the kids college savings account could be modeled with an equation to help my math brain see the big picture.
Currently, our savings account for the kids college is modeled by A of x equals 20000 times 1.05 raised to the x minus 1 power .
He explained that with inflation that we really needed to have a steady increase in our savings to be able to pay for both kids college funds. Stephen suggested that we look at how much money we would have if we didn't deposit any more money in our savings account and just relied on the interest to build based on this equation. He gave us a random number of 5% for the interest rate as shown in the model above and x is the number of years.
A) Is this sequence arithmetic, geometric, or neither?
B) Break apart the equation -Tell me what each of those terms represent above in the A(x) equation.
C) How much money would we have if we only did interest on this account in 11 years when Kolton starts college?
SHOW ALL MATH WORK AND EXPLANATIONS FOR THIS FROM START TO FINISH! IT'S A 10 POINT PROBLEM!
Answer:
A) This sequence is geometric.
B) In the equation A(x) = 20000(1.05)^(x-1):
A(x) represents the amount of money in the savings account after x years.
20000 represents the initial amount of money in the savings account.
1.05 represents the interest rate, which is compounded annually.
(x-1) represents the number of compounding periods, which is one less than the number of years because the initial amount is not compounded.
C) To find out how much money we would have in the savings account in 11 years when Kolton starts college, we can substitute x = 11 into the equation and simplify:
A(11) = 20000(1.05)^(11-1)
A(11) = 20000(1.05)^10
A(11) ≈ 35,123.58
Therefore, if we only relied on the interest to build our savings for 11 years, we would have approximately $35,123.58 in the savings account when Kolton starts college. However, this amount may not be enough to cover the total cost of college, so it is important to continue making regular deposits to the savings account.
pizzas are sized by diameter. what percent increase in area results if chantel's pizza increases from a 10-inch pizza to a 12-inch pizza?
Step-by-step explanation:
Area of circle = pi r^2
10 inch = pi (5)^2 = 25 pi
12 inch = pi (6)^2 = 36 pi
12 inch is 11pi bigger
percentage: 11 pi is what percentage of 25 pi ?
11 pi / 25 pi x 100% = 44 % bigger
The area of a pizza increases with the square of the diameter. Therefore, a 10-inch pizza has an area of [tex]π*(10/2)^2= 78.54[/tex] square inches, and a 12-inch pizza has an area of [tex]π*(12/2)^2 = 113.10[/tex] square inches. This is an increase of 113.10 - 78.54 = 34.56 square inches, or an increase of 44.2%.
To explain further, the diameter of a pizza is measured from one side to the other through the center of the pizza. As the diameter of the pizza increases, the area of the pizza increases. This is because the area of a pizza is calculated as [tex]π*(d/2)^2[/tex], where d is the diameter. So, if the diameter increases, the area increases as well.
For example, if a 10-inch pizza has an area of 78.54 square inches, a 12-inch pizza would have an area of 113.10 square inches. This is an increase of 113.10 - 78.54 = 34.56 square inches, or an increase of 44.2%. This is because the diameter of the pizza has increased by 2 inches (10 inches to 12 inches), and the area has increased by 44.2%.
It is important to note that increasing the diameter of the pizza does not just increase the circumference of the pizza, but also the area. The increase in area is directly related to the increase in diameter, and can be calculated by taking the difference between the areas of the two pizzas.

find 3 consecutive odd integers such that 3 times the sum of the first and second equals 13 less than the third
Three consecutive odd integers are -3, -1, and 1.
A detailed explanation of the answer.
To find 3 consecutive odd integers such that 3 times the sum of the first and second equals 13 less than the third, we can follow these steps:
Let's assume that the first odd integer is x.Thus, the second odd integer will be x + 2, and the third odd integer will be x + 4.The sum of the first and second odd integers is x + (x + 2) = 2x + 2.Three times the sum of the first and second odd integers is 3(2x + 2) = 6x + 6.Thirteen less than the third odd integer is (x + 4) - 13 = x - 9.Thus, the equation can be written as 6x + 6 = x - 9. Solving for x gives us x = -3.Then, the three consecutive odd integers are x, x + 2, and x + 4, which are -3, -1, and 1, respectively.Therefore, the three consecutive odd integers are -3, -1, and 1.

Evelyn buys bracelets thats cost $6 each and three purses that cost $12 each. The cost of evelyns total purchase is $60. Write and equation thar can be used to find n, the number of bracelets that evelyn buys
b + 2p = 10 ,we have an equation that relates the number of bracelets to the number of purses and the total cost of the purchase. if Evelyn buys two purses, she also buys six bracelets.
Let's start by defining our variables. We'll let "b" represent the number of bracelets that Evelyn buys and "p" represent the number of purses she buys.
We know that each bracelet costs $6 and each purse costs $12. We also know that her total purchase is $60.
Using this information, we can create an equation:
6b + 12p = 60
Now we want to solve for "b", which represents the number of bracelets. To do this, we need to isolate "b" on one side of the equation. We can start by simplifying the equation by dividing both sides by 6:
b + 2p = 10
Now we have an equation that relates the number of bracelets to the number of purses and the total cost of the purchase. We can use this equation to find the value of "b" given any value of "p". For example, if Evelyn buys two purses, we can substitute "p = 2" into the equation and solve for "b":
b + 2(2) = 10
b + 4 = 10
b = 6
So if Evelyn buys two purses, she also buys six bracelets.
In general, we can see that the equation tells us that for every two purses that Evelyn buys, she buys one less bracelet. This makes sense because purses are more expensive than bracelets, so as she buys more purses, she can afford fewer bracelets.

Book I, Problem 18. Find three numbers such that the sum of any pair exceeds the third by a given amount; say the given excesses are 20, 30, and 40. (Hint: Let the sum of all three numbers be 2x. Add number (3) to both sides of the equation (1) + (2) = (3) + 20 to get (3) = x – 10. Obtain expressions for (1) and (2) similarly.]
a = 5, b = 25, c = 0
step by step explanation:
Let the three numbers be a, b, and c. Then, we have the following system of equations:
a + b = c + 20 (1)
a + c = b + 30 (2)
b + c = a + 40 (3)
Adding all three equations together, we get:
2(a + b + c) = 90
Simplifying, we get:
a + b + c = 45
Now, using the hint given in the problem, we can write:
c = x - 10
b = a + 20
a + (a + 20) = (x - 10) + 30
Simplifying this equation, we get:
2a + 20 = x + 20
Solving for x, we get:
x = 2a
Substituting this value of x in the equation c = x - 10, we get:
c = 2a - 10
Now we can express b and c in terms of a:
b = a + 20
c = 2a - 10
Therefore, three numbers that satisfy the given conditions are:
a = 5, b = 25, c = 0
We can verify that the sum of any pair exceeds the third by the given amounts:
a + b = 30 > c + 20 = 20
a + c = 5 > b + 30 = 25
b + c = 15 > a + 40 = 45

Jason worked for 14/3 hours on Monday, and his friends Sheldon worked for 25/6 hours.How many more hours did Jason work than Sheldon?
Answer:
Step-by-step explanation:
To find out how many more hours Jason worked than Sheldon, we need to subtract the number of hours Sheldon worked from the number of hours Jason worked:
Jason's hours = 14/3
Sheldon's hours = 25/6
Jason's hours - Sheldon's hours = (14/3) - (25/6)
To subtract fractions, we need to have a common denominator, which in this case would be 6:
(14/3) - (25/6) = (28/6) - (25/6) = 3/6
Simplifying the result, we get:
3/6 = 1/2
Therefore, Jason worked 1/2 more hours than Sheldon.
Jason worked 1/3 more hours than Sheldon.
To find out how many more hours Jason worked than Sheldon, we need to subtract the number of hours Sheldon worked from the number of hours Jason worked.
Jason worked for 14/3 hours, which can be simplified to 4 and 2/3 hours. Sheldon worked for 25/6 hours, which can be simplified to 4 and 1/6 hours.
Subtracting the hours Sheldon worked from the hours Jason worked, we get: 4 and 2/3 - 4 and 1/6 = 2/3 - 1/6 = 1/3.

.a semi-elliptical arch in a stone bridge has a span of 6 meters and a central height of 2 meters. find the height of the arch at a distance of 1.5 m from the center of the arch.
The height of the arch at a distance of 1.5 meters from the center is approximately D. 1.73 meters
The shape of a semi-elliptical arch can be described by the equation:
y = c * sqrt(1 - (x/a)^2)
where "a" is half the span of the arch, "c" is the central height of the arch, and (x,y) are the coordinates of a point on the arch, measured relative to the center of the arch.
In this case, we have a span of 6 meters, so a = 3 meters. The central height of the arch is 2 meters, so c = 2 meters. We want to find the height of the arch at a distance of 1.5 meters from the center, so x = 1.5 meters.
Substituting these values into the equation, we get:
y = 2 * sqrt(1 - (1.5/3)^2)
y = 2 * sqrt(1 - 0.25)
y = 2 * sqrt(0.75)

If the anticipated claim outcome actually occurs, it will be feasible to get in touch with the entity once more; if it isn't, both crucial systems will undoubtedly miss the statement.
Here,
We must first determine how much is deducted from Claire's gross salary annually for the 401(k) plan in order to determine
how much money is deposited into her retirement account by her employer each month.
Since we are aware that Claire contributes 5% of her total income to her 401(k),
we can figure out how much she contributes as follows:
=> 0.05 x $92,400 = $4,620
As a result, Claire's 401(k) plan deducts $4,620 from her total income each year. We can reduce this amount by 12 (the number of months in a year) to determine how much it is per month:
=> $4,620 ÷ 12 = $385
As a result, Claire's employer contributes $385 each month to her 401(k) savings account.

Yes, I can find the absolute value of -3 2/3.
The absolute value of a number is the distance of the number from zero on the number line. It is always a positive number.
To find the absolute value of -3 2/3, we need to ignore the negative sign and just look at the magnitude of the number.
So, the absolute value of -3 2/3 is:
|-3 2/3| = 3 2/3
Therefore, the absolute value of -3 2/3 is 3 2/3.
Enola has x quarters and y dimes. She has a minimum of 18 coins worth at most $3.60 combined. Solve this system of inequalities graphically and determine one possible solution.
Answer: Let's start by setting up the system of inequalities:
x + y ≥ 18 (Enola has at least 18 coins)
0.25x + 0.10y ≤ 3.60 (The total value of her coins is at most $3.60)
To graph this system of inequalities, we can start by graphing the line x + y = 18 (the boundary for the first inequality). This line represents all the possible combinations of x and y that would give Enola exactly 18 coins. To graph this line, we can plot two points on it and connect them with a straight line. For example, if x = 0, then y = 18, and if y = 0, then x = 18. So the line passes through the points (0, 18) and (18, 0).
Next, we need to shade the region that satisfies the second inequality. To do this, we can rearrange the inequality to get:
y ≤ (3.60 - 0.25x) / 0.10
This inequality represents all the possible combinations of x and y that would give Enola a total value of coins at most $3.60. We can graph this inequality by shading the region below the line y = (3.60 - 0.25x) / 0.10.
Putting both of these graphs together, we get:
Graph of system of inequalities
One possible solution to this system of inequalities is (x, y) = (10, 8). This corresponds to Enola having 10 quarters and 8 dimes, for a total of 18 coins. The total value of her coins is:
0.25(10) + 0.10(8) = 2.50 + 0.80 = 3.30
Since 3.30 is at most $3.60, this solution satisfies both inequalities. Note that there may be other possible solutions as well.
Step-by-step explanation:
The system of inequalities is solved by plotting the inequalities in the xy-plane and finding the overlapping region. One possible solution for the number of quarters (x) and dimes (y) Enola could have that meets the conditions is x = 8 and y = 10.
Explanation:The subject of this question is inequalities. Enola has x quarters and y dimes. Each quarter is worth $0.25 and each dime is worth $0.10. Therefore, the total amount of money she has is $0.25x + $0.10y. Since she has at least 18 coins, we have the inequality x + y >=18. Since the total money is at most $3.60, we have the inequality $0.25x + $0.10y <= 3.60. Because we are dealing with a whole number of coins, x and y should be integers. The solution of this system of inequalities can be found graphically by plotting these inequalities in the xy-plane and finding the overlapping region. One possible solution is x = 8 and y = 10.

johnny read 30 pageson monday. opn tuesday he read 1/8 of the book. on wednesday he read the remaining 1/4. how many pages
Johnny read 30 pages on Monday. On Tuesday he read 1/8 of the book. On Wednesday he read the remaining 1/4. How many pages did he read in total?To find out how many pages Johnny read in total, we need to first determine the total number of pages in the book. We know that he read 1/8 of the book on Tuesday and the remaining 1/4 on Wednesday. So we can add these two fractions to find out the total fraction of the book that he read:1/8 + 1/4 = 3/8Now we know that Johnny read 3/8 of the book. We can use this information to set up a proportion to find out how many pages he read in total:3/8 = x/total number of pagesTo solve for x, we can cross-multiply and simplify:3/8 * total number of pages = xMultiply both sides by 8/3:total number of pages = x * 8/3Now we need to find out what x is. We know that Johnny read 30 pages on Monday, which is 1/8 of the total number of pages. So we can use this information to set up another proportion:1/8 = 30/total number of pagesTo solve for the total number of pages, we can cross-multiply and simplify:1/8 * total number of pages = 30Multiply both sides by 8:total number of pages = 240Now we can substitute this value for the total number of pages in our previous equation to find out how many pages Johnny read in total:total number of pages = x * 8/3240 = x * 8/3Multiply both sides by 3/8:x = 90Therefore, Johnny read a total of 30 + 90 = 120 pages.
one-tailed two-tailed a) a pharmacist wants to test whether the effect of a placebo is different from zero. b) holdem motors wants to test whether the mean time to assemble a car is less than 24 hours. c) ihi insurance wants to test whether the mean time to process a claim is less than 7 days
The appropriate type of test for each scenario is a) a two-tailed test, b) a one-tailed test, and c) a one-tailed test.
a) This would be a two-tailed test as the pharmacist is testing for a difference, rather than a specific direction of effect.
b) This would be a one-tailed test as Holdem Motors is specifically testing whether the mean time to assemble a car is less than 24 hours, rather than testing for a difference in either direction.
c) This would be a one-tailed test as IHI Insurance is specifically testing whether the mean time to process a claim is less than 7 days, rather than testing for a difference in either direction.

your cousin says that if two fractions have the same numerator,then the fraction with the greater denominator is the greater fraction. is your cousin correct explain
It is not always true that if two fractions have the same numerator, then the fraction with the greater denominator is the greater fraction.
The statement that if two fractions have the same numerator, then the fraction with the greater denominator is the greater fraction is not always correct. This is because the value of a fraction is determined by both its numerator and denominator, and if the denominators of two fractions with the same numerator are different, then the fractions are not directly comparable.
Consider the fractions 3/4 and 3/5. Both have a numerator of 3, but the denominator of the first fraction is greater than the denominator of the second fraction. However, 3/5 is actually the greater fraction because it represents a larger portion of the whole.Consider the fractions 5/7 and 5/9. Both have a numerator of 5, but the denominator of the second fraction is smaller than the denominator of the first fraction. Therefore, 5/7 is the greater fraction because it represents a larger portion of the whole.

the radius of a sphere decreases at a rate of 3 m / s . find the rate at which the surface area decreases when the radius is 8 m . answer exactly or round to 2 decimal places.
The rate at which the surface area of the sphere is decreasing when the radius is 8 meters and decreasing at a rate of 3 m/s is approximately -192π square meters per second.
Let's start by finding the formula for the surface area of a sphere. The surface area (A) of a sphere with radius (r) is given by the formula:
A = 4πr²
Now, we need to find the rate at which the surface area is changing with respect to time (t) when the radius is 8 meters and the rate of change of radius is 3 m/s.
To find dA/dt, we need to differentiate the formula for surface area with respect to time, using the chain rule:
dA/dt = d/dt (4πr²) = 8πr (dr/dt)
Here, we have used the fact that the derivative of r² with respect to time is 2r (dr/dt) by the chain rule. Now, we can substitute the given values into the formula to find the rate of change of surface area:
r = 8 m (given)
dr/dt = -3 m/s (negative sign because the radius is decreasing)
π ≈ 3.14 (constant)
dA/dt = 8πr (dr/dt)
dA/dt = 8π(8)(-3)
dA/dt = -192π

Find the volume of the triangular prism below
We can claim that after answering the above question, the As a result, the triangular prism has a volume of 240 cubic centimetres.
what is prism?A prism is a polyhedron with an n-sided polygonal basis, a second base that is a shifted copy of the first base, and n extra faces (necessarily all parallelograms), with two connecting the corresponding sides of the base. All cross sections that are parallel to the base are translations of it. A prism is a two-sided, solid, three-dimensional object with two faces. It has the same cross-sections, flat sides, and similar bases. Faces of a prism are parallelograms or rectangles with no bases. A prism is a refracting item that is homogeneous, solid, and transparent, contained by two planes that are obliquely oriented to one another. A typical prism has two triangular faces and three parallel rectangular faces. They are made of either glass or metal.
To calculate the volume of a triangular prism, multiply the area of the triangular base by the prism's height.
Triangle area = 1/2 * base * height
Triangle area = 1/2 * 8 cm * 6 cm
Triangle area = 24 cm2
We must now determine the prism's height. The diagram shows that the prism has a height of 10 cm.
Finally, the volume of the triangular prism can be calculated by multiplying the area of the triangle base by the prism's height:
Prism volume = base area * The prism's height
Prism volume = 24 cm2 * 10 cm
Prism volume = 240 cm3
As a result, the triangular prism has a volume of 240 cubic centimeters.

bobby has 37 pineapples and johnny has 35 times more pineapples than bobby. how many more pineapples does johnny have than bobby?
Johnny has 1258 more pineapples than Bobby.
Bobby has 37 pineapples, Johnny has 35 times more pineapples than Bobby. To find how many more pineapples does Johnny have than Bobby, we can use the below formula,
More pineapples = Johnny's pineapples - Bobby's pineapples
Let x be the number of pineapples that Bobby has. Therefore, the number of pineapples owned by Johnny is 35x.
It is given that Bobby originally has 37 pineapples, thus x = 37. The number of pineapples Johnny has = 35*37 = 1295
Thus, difference in number of pineapples between Johnny and Bobby:
=1295-37 = 1258
Therefore, Johnny has 1258 more pineapples than Bobby.
