teri's car holds 17.4 gallons og gas. if she can drive 478.5 miles ona full tank of gas, how many miles can she per gallons

Answers

Answer 1

Teri can drive approximately 27.47 miles per gallon of gas.

To find how many miles per gallon Teri can drive, we need to divide the total distance she can travel on a full tank of gas by the amount of gas she needs to fill the tank. This gives us the average number of miles she can travel on one gallon of gas.

Teri's car can hold 17.4 gallons of gas.

Teri can drive 478.5 miles on a full tank of gas.

Mathematically, we can represent this as:

Miles per gallon = Total distance traveled ÷ Amount of gas used

Plugging in the values we have:

Miles per gallon = [tex]\frac{478.4 miles}{17.4 gallons}[/tex]

Performing the division:

Miles per gallon = 27.47126437

Rounding to two decimal places, we get:

Miles per gallon ≈ 27.47

The length of the base with area 25/18 square meters is 5/3 meters. This answer is in its simplest form.

What is height of triangle?

The height of a triangle is the length of the line segment that is drawn from the vertex of the triangle perpendicular to the base.

The area of a triangle is given by the equation

A = 1/2 * base * height.

Therefore, we can substitute the value of the area and the height of the triangle into the equation to solve for the base.

A = 1/2 * b * (5/3)

25/18 = 1/2 * b * (5/3)

We will divide left side of the equation by 5/3.

(25/18) / (5/3) = (1/2)*b

(25/18) * 3/5 = (1/2)*b

Now, we can solve for b by dividing the left side of the equation by 1/2

(5/6) / (1/2) = b

b = 5/6 * (2/1)

b = 5/3

Therefore, the length of the base is 5/3 meters. This answer is in its simplest form.

An arc of a circle radius 7cm is 14cm long. What angle does the arc subtend at the centre? (π =22/7). ​

Answers

The central angle of the given arc, subtending a circle with a radius of 7 cm and a length of 14 cm, is approximately 103.13 degrees.

What is arc of a circle?

An arc is a section of a circle's or curve's border in mathematics. It is additionally known as an open shape. The circumference, also referred to as the perimeter, is the measurement around a circular that defines its edge. Consequently, the arc is defined as the separation between any two locations along its circumference.

The angle that an arc of a circle subtends at the center is called the central angle. The central angle is measured in degrees and is formed by the radii that make up the arc.

Given:

Radius of the circle (r) = 7 cm

Length of the arc (s) = 14 cm

To find the central angle (θ) of the arc, we can use the formula:

θ = (s / r) * (180 / π)

where:

s = length of the arc

r = radius of the circle

π = pi (approximately 3.14159...)

Plugging in the given values:

θ = (14 / 7) * (180 / π)

θ = 2 * (180 / π)

θ ≈ 103.13 degrees (rounded to two decimal places)

So, the central angle of the given arc, subtending a circle with a radius of 7 cm and a length of 14 cm, is approximately 103.13 degrees.

Darrius is single and lives in Pennsylvania, which has a state income tax rate of 3.07%. He earns an annual salary of $42,350. Calculate his monthly take-home pay.

Answers

Answer:

To calculate Darrius' monthly take-home pay, we first need to calculate his annual state income tax. We do this by multiplying his yearly salary by the state income tax rate:

$42,350 x 3.07% = $1,292.94

Next, we subtract the state income tax from his annual salary to get his annual net income:

$42,350 - $1,292.94 = $41,057.06

Finally, we divide his annual net income by 12 to get his monthly take-home pay:

$41,057.06 / 12 = $3,421.42

Therefore, Darrius' monthly take-home pay is $3,421.42.

Topic: Linear Diophantine Equation
Solve: Find x,y∈Z such that 123x + 360y = 99

Answers

The solution to the equation 123x + 360y = 99 is x = 22 and y = -11.

What is Linear Diophantine Equation?

An equation with two or more integer unknowns that are all to a maximum degree of one is known as a linear diophantine equation (LDE).

To solve the equation 123x + 360y = 99, we can use the extended Euclidean algorithm, which is a method for finding the greatest common divisor (GCD) of two integers and expressing it as a linear combination of those integers. We can use the same algorithm to find a solution to the given equation.

First, we need to find the GCD of 123 and 360. We can use the Euclidean algorithm for this:

gcd(123, 360) = gcd(123, 360 - 123*2) = gcd(123, 114)

gcd(123, 114) = gcd(123 - 114, 114) = gcd(9, 114)

gcd(9, 114) = gcd(9, 114 - 9*12) = gcd(9, 6)

gcd(9, 6) = gcd(9 - 6*1, 6) = gcd(3, 6)

gcd(3, 6) = gcd(3, 6 - 3*2) = gcd(3, 0)

gcd(3, 0) = 3

Therefore, the GCD of 123 and 360 is 3.

Now we can use the extended Euclidean algorithm to find integers s and t such that 123s + 360t = 3. This is done by working backwards through the Euclidean algorithm and expressing each remainder as a linear combination of the previous two integers:

gcd(123, 360) = 3

3 = 123s + 360t

3 = 9 - 114

 = 9 - (360 - 123*2)

 = 123*2 - 360*1

s = 2, t = -1

Now we can multiply both sides of the equation by 33 to get a solution to the original equation:

123x + 360y = 99

123*2*33 + 360*(-1)*33 = 3*33

123*66 + 360*(-33) = 99

Finally, we can divide both sides by 3 to get a solution in integers:

123*22 + 360*(-11) = 33

Therefore, x = 22 and y = -11 is a solution to the equation 123x + 360y = 99.

1 The points (-8, 5) and (-4, r) lie on a line with slope 1/4. Find the missing coordinate r.​

Answers

Answer:

Step-by-step explanation:

We can use the slope formula to find the slope of the line passing through the two given points:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-8, 5) and (x2, y2) = (-4, r).

Substituting these values, we have:

1/4 = (r - 5) / (-4 - (-8))

1/4 = (r - 5) / 4

r - 5 = 1

r = 6

Un chef observó que el 65 % de todos sus clientes consume mayonesa, el 70 % consume kétchup y el 80 % consume mayonesa o kétchup. ¿Cuál es la probabilidad de que un cliente consuma las dos salsas al mismo tiempo​

Answers

The probability that a customer Consumes both mayonnaise and ketchup at the same time is 0.55 or 55%.

To find the probability that a customer consumes both mayonnaise and ketchup at the same time, we need to use the concept of intersection in probability theory. The intersection represents the overlap or commonality between two events, in this case, the consumption of mayonnaise and ketchup.

Given that 80% of customers consume either mayonnaise or ketchup, we can assume that this includes the customers who consume both. Let's call the event of consuming mayonnaise "M" and the event of consuming ketchup "K". Therefore, we know that P(M U K) = 0.8.

To find the probability of consuming both, we can use the formula P(M ∩ K) = P(M) + P(K) - P(M U K), where ∩ represents the intersection. We can substitute the values we have been given to get:

P(M ∩ K) = 0.65 + 0.70 - 0.8 = 0.55

Therefore, the probability that a customer consumes both mayonnaise and ketchup at the same time is 0.55 or 55%. This means that more than half of the customers consume both, indicating that the chef could consider offering dishes that combine both sauces to cater to this preference.

Answers

the probability of selecting a tool produced by the old method on the first attempt and a tool produced by the new method on the second attempt is:

P(A and B) = P(A) * P(B | A) = 0.8305 * 0.1998 = 0.1660

How to solve the questions?

Part A:

Let A be the event that the first tool selected is acceptable and B be the event that the second tool selected is acceptable.

We need to find the probability of P(A and B), which can be calculated using the multiplication rule of probability as follows:

P(A and B) = P(A) * P(B | A)

where P(A) is the probability of selecting an acceptable tool on the first attempt and P(B | A) is the conditional probability of selecting an acceptable tool on the second attempt given that the first tool selected was acceptable.

P(A) = (1640 + 328) / (1640 + 328 + 23 + 9) = 0.985

P(B | A) = (1639 + 327) / (1640 + 328 + 23 + 9 - 1) = 0.985

Therefore, the probability of both selections being acceptable is:

P(A and B) = P(A) * P(B | A) = 0.985 * 0.985 = 0.9702

The events are dependent because the probability of selecting an acceptable tool on the second attempt depends on the result of the first attempt.

Part B:

Let A be the event that the first tool selected is produced by the old method and B be the event that the second tool selected is produced by the new method.

We need to find the probability of P(A and B), which can be calculated using the multiplication rule of probability as follows:

P(A and B) = P(A) * P(B | A)

where P(A) is the probability of selecting a tool produced by the old method on the first attempt and P(B | A) is the conditional probability of selecting a tool produced by the new method on the second attempt given that the first tool selected was produced by the old method.

P(A) = (1640 + 23) / (1640 + 328 + 23 + 9) = 0.8305

P(B | A) = 328 / (1640 + 328 + 23 + 9 - 1) = 0.1998

Therefore, the probability of selecting a tool produced by the old method on the first attempt and a tool produced by the new method on the second attempt is:

P(A and B) = P(A) * P(B | A) = 0.8305 * 0.1998 = 0.1660

The events are dependent because the probability of selecting a tool produced by the new method on the second attempt depends on the result of the first attempt.

Pete wants to put a fence around a rectangular section of his backyard.
The space he wants to enclosc measures 30 feet in length, and it is as
wide. How many feet of fencing does he need?
(1) 10
(2) 30
(3) 40
(4) 80
(5) 120

Answers

Answer:

(5) 120.

Step-by-step explanation:

To calculate the amount of fencing needed to enclose a rectangular area, we need to find the perimeter of the rectangle. The perimeter is the sum of the lengths of all four sides.

In this case, we are told that the rectangular section of Pete's backyard measures 30 feet in length and is also 30 feet wide.

Therefore, the perimeter of the rectangle is:

P = 2L + 2W

where L is the length and
W is the width of the rectangle.

Substituting the given values, we get:

P = 2(30) + 2(30) = 60 + 60 = 120

Therefore, Pete needs 120 feet of fencing to enclose the rectangular section of his backyard.

There is a 20% chance that a particular volcano will erupt during any given decade. A random number generator generated 10 sets of random numbers from 1 to 5 as shown. The number 1 represents the volcano erupting. Find the experimental probability that the volcano will erupt in 1 or 2 of the next 5 decades

Answers

The experimental probability of the volcano erupting in 1 or 2 of the next 5 decades is 6/10 or 0.6.

We can do this by assigning a value of 1 to the numbers 1 and 2 (representing the volcano erupting) and a value of 0 to

the numbers 3, 4, and 5 (representing the volcano not erupting).

For each set of random numbers generated, we can count the number of times the volcano erupted (i.e. the sum of the

values assigned to the numbers 1 and 2).

Out of the 10 sets of random numbers generated, we might get results like this:
Set 1: 1 3 4 2 1 (2 eruptions)
Set 2: 2 1 5 4 3 (2 eruptions)
Set 3: 3 2 5 4 5 (1 eruption)
Set 4: 1 1 2 4 5 (3 eruptions)
Set 5: 4 4 4 4 4 (0 eruptions)
Set 6: 1 1 1 1 1 (5 eruptions)
Set 7: 3 3 3 3 3 (0 eruptions)
Set 8: 2 2 2 2 2 (0 eruptions)
Set 9: 1 2 1 2 1 (4 eruptions)
Set 10: 5 5 5 5 5 (0 eruptions)

Out of these 10 sets, we can see that there were 6 sets where the volcano erupted in 1 or 2 of the next 5 decades (sets

1, 2, 3, 4, 9, and 10). Therefore, the experimental probability of the volcano erupting in 1 or 2 of the next 5 decades is

The period p of a pendulum, or the time it takes for the pendulum to make one complete swing, varies directly as the square root of the length L of the pendulum. If the period of a pendulum is 1.8 s when the length is 2 ft, find the period when the length is 3 ft.

Answers

The period of the pendulum when the length is 3 ft is approximately 2.08 seconds.

What is the period?

We are given that the period P varies directly as the square root of the length L of the pendulum. We can write this as:

P ∝ √L

Using a proportionality constant k, we can write this as an equation:

P = k√L

To find the value of k, we can use the information given in the problem: when L = 2 ft, P = 1.8 s. Substituting these values into the equation, we get:

1.8 = k√2

To solve for k, we can isolate it by dividing both sides by √2:

k = 1.8 / √2

Now we can use this value of k to find the period when the length is 3 ft. Substituting L = 3 ft and the value of k we just found into the equation, we get:

P = k√L

P = (1.8 / √2) √3

P ≈ 2.08 seconds

Therefore, the period of the pendulum when the length is 3 ft is approximately 2.08 seconds.

To convert 1/2% to a ratio, we first convert it to a decimal by dividing by 100:

1/2% = 1/2 ÷ 100 = 0.005

Then we express this decimal as a ratio by putting it in the form of x:y:

0.005 = x:y

To simplify this ratio, we can multiply both sides by a factor that will make x and y whole numbers. For example, we can multiply both sides by 100:

0.005 × 100 = x:y × 100

0.5 = x:y

So 1/2% as a ratio is 1:200.

1/2% is equivalent to 0.5% or 0.005 as a decimal.

To express 0.005 as a ratio, you can write it as a fraction with a numerator of 0.005 and a denominator of 1. Then, you can multiply both the numerator and denominator by 100 to get rid of the decimal and express it as a ratio.

0.005/1 = (0.005

Therefore, 1/2% is equivalent to the ratio 0.5:100 or 1:200.

Hοw tο find Z-scοre cοrrespοnding tο the cutοff pοint?

We can use the Z-scοre fοrmula tο find the Z-scοre cοrrespοnding tο the cutοff pοint:

Z = (X - μ) / σ

where X is the head breadth we want tο find, μ is the mean head breadth, σ is the standard deviatiοn, and Z is the Z-scοre cοrrespοnding tο the cutοff pοint.

We want tο find the Z-scοre such that the area tο the right οf it under the standard nοrmal distributiοn curve is 0.025. We can use a standard nοrmal distributiοn table οr calculatοr tο find this Z-scοre, which turns οut tο be apprοximately 1.96.

Tο find the maximum head breadth that the helmets will fit, we need tο find the cutοff pοint beyοnd which the head breadths are in the largest 2.5%.

Nοw we can sοlve fοr X:

1.96 = (X - 6.0) / 1.0

X - 6.0 = 1.96

X = 7.96

two squares of length x are cut out of adjacent corners of an 18 inch by 18 inch piece of cardboard and two rectangles of length 9 and width x are cut out of the other two corners of the cardboard (see figure below) the resulting piece of cardboard is then folded along the dashed lines to form a closed box. Find the dimensions and volume of the largest box that can be formed in this way.

Answers

Answer:

3 in × 6 in × 12 in216 in³

Step-by-step explanation:

You want the dimensions and volume of a cuboid that can be made from an 18 in square of cardboard when an x-inch square is cut from two adjacent corners, and an x-inch by 9-inch rectangle is cut from the other two corners.

Dimensions

The longest side of the cuboid will have length (18 -2x). The second longest side will have length (18 -9 -x) = (9 -x). The shortest side will have length x.

Volume

The volume of the cuboid is the product of these side lengths:

  V = (18 -2x)(9 -x)(x) = 2x(9 -x)²

Maximum volume

The value of x that maximizes volume will be the value that makes the derivative with respect to x be zero.

  V' = 2(9 -x)² -4x(9 -x) = (9 -x)(2(9 -x) -4x) = 2(9 -x)(9 -3x)

  V' = 6(9 -x)(3 -x)

The derivative will be zero when its factors are zero, at x=9 and x=3. The value x=9 gives zero volume.

The value x=3 gives a volume of ...

  V = 2·3(9 -3)² = 6³ = 216 . . . . . cubic inches

The dimensions are ...

x = 39 -x = 9 -3 = 618 -2x = 18 -6 = 12

The dimensions for maximum volume are 3 inches by 6 inches by 12 inches. The maximum volume is 216 cubic inches.

If I watch tv 4 days out of 7 each and I watch 28 days how many days will I watch tv i NEED THIS ASAP

Answers

you will watch TV for approximately 16 days out of the 28 days.

If you watch TV for 4 days out of 7 each week, then the fraction of the week that you spend watching TV is:

4/7

To find the total number of days you will watch TV over 28 days, you can use the proportion:

4/7 = x/28

where x is the number of days you will watch TV.

To solve for x, you can cross-multiply:

4 * 28 = 7 * x

112 = 7x

x = 112/7

x ≈ 16

Therefore, you will watch TV for approximately 16 days out of the 28 days.

What is proportion?

Proportion is a mathematical concept that expresses the relationship between two quantities or values. It is often represented as a fraction, with the numerator and denominator representing the values being compared.

In a proportion, the two ratios are equal. For example, if you have a bag of marbles containing 6 red marbles and 4 blue marbles, the proportion of red to blue marbles is 6:4, or 3:2. This can also be written as a fraction: 3/2.

Proportions are useful in many areas of mathematics and everyday life, including geometry, statistics, and finance. They are also used in problem-solving to find missing values or to determine if two values are proportional to each other.

What is a triangle?

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

Here, we have

Given:

∠A = 33.7°

∠C = 26.4°

We have to find the value of b.

Let's label the missing side as b, and use sin(A) = opposite/hypotenuse to find the length of the side opposite angle A:

sin(A) = opposite/hypotenuse

sin(33.7°) = b/8

b = 8 × sin(33.7°)

b ≈ 4.726

Hence, the length of the missing side is approximately 4.73 units.
