What expression represents the total area of the
shaded figure. Simplify your expression.
Answers
The total area of the shaded portion is (x² - 16)(x²- 1) square meters.
What is a square?Square is a regular quadrilateral, which has all the four sides of equal length and all four angles are also equal. The angles of the square are at right-angle or equal to 90-degrees. Also, the diagonals of the square are equal and bisect each other at 90 degrees.
Equation:The area of the outer square is (x² - 8)², and the area of the inner square is x². Therefore, the area of the shaded region can be found by subtracting the area of the inner square from the area of the outer square:
Area of shaded region = Area of outer square - Area of inner square
= (x² - 8)² - x²
Expanding the first term using the formula for the square of a binomial, we get:
Area of shaded region = (x⁴ - 16x² + 64) - x²
= x⁴ - 17x² + 64
Therefore, the expression that represents the total area of the shaded figure is x⁴ - 17x² + 64, which can be simplified by factoring:
x⁴ - 17x² + 64 = (x² - 16)(x² - 1)
So the simplified expression for the total area of the shaded figure is (x² - 16)(x²- 1).

The ratio of A to B is 1 : 2 and B to C is 3 : 4. If C has the value of 32, what is the sum of the three numbers?
Answers
Answer:
A + B + C = 68
Step-by-step explanation:
A : B = 1 : 2
B : C = 3 : 4
Find the LCM of 2 and 3. LCM = 6
Multiply A : B by 3 and B : C by 2
[tex]\dfrac{A}{B}=\dfrac{1}{2}=\dfrac{1*3}{2*3}=\dfrac{3}{6}\\\\\\\dfrac{B}{C }=\dfrac{3}{4}=\dfrac{3*2}{4*2}=\dfrac{6}{8}[/tex]
A : B = 3 : 6 & B : C = 6 :8
A : B : C = 3 : 6 : 8
A = 3x
B = 6x
C = 8x
It is given that C is 32.
8x = 32
Divide both sides by 8
x = 32÷ 8
x = 4
A = 3*4 = 12
B = 6 * 4 = 24
Sum of three numbers = 12 + 24 + 32

Answers
Farmers Products Inc. should disclose a contingent liability in its 2016 financial statements for the lawsuit filed against them due to a collision caused by one of their delivery truck drivers.
Based on the information provided, it appears that as of the date of the financial statements (March 3, 2017), Farmers Products would need to disclose a contingent liability related to the lawsuit filed against them by the other driver.
A contingent liability is a potential liability that may arise from past events but the outcome is uncertain and will depend on future events. In this case, the lawsuit filed against Farmers Products by the other driver represents a potential liability that may result in damages being awarded against the company.
Under accounting standards, a contingent liability should be disclosed in the notes to the financial statements if it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. In this case, it is probable that Farmers Products may be liable for damages resulting from the accident and the estimated damages fall within a reasonable range of $6,000 to $10,000.
Therefore, in the notes to its 2016 financial statements, Farmers Products should disclose the existence of the lawsuit and the potential liability that may result. The disclosure should also include an estimate of the potential damages, if any, and any other relevant information about the lawsuit.

Hi! Based on the given information and without a visual of the graph, I will provide a general answer using the terms provided. Please note that an accurate response may require additional information or context.
The slope of the line of best fit indicates the rate of change in the value of the house over time, and a positive slope signifies that the value has increased. However, the y-intercept of the line of best fit does not necessarily mean that it cost $9,994 to build the house.
The y-intercept represents the estimated value of the house when the independent variable (usually time) is zero, but it does not account for factors like construction costs, inflation, or changes in the real estate market.

Given: D = 8 1/2 in.
We know that the diameter of a circle is twice the radius. Therefore, we can find the radius by dividing the diameter by 2:
radius (r) = D/2 = 8 1/2 / 2 = 4 1/4 in.
To find the circumference (C) of the circle, we can use the formula:
C = 2πr
where π (pi) is a constant approximately equal to 3.14.
Substituting the value of r, we get:
C = 2π(4 1/4) = 2π(17/4) = 8.5π

There are three possible cases (or scenarios) for how many solutions that an absolute value equation could have. How many solutions are there for each case? Why are their differences in the number of solutions? Give a mathematical example in your explanation.
PLS HELP ASAP
Answers
Consider the equation |x-4| = 5. This equation has two solutions since the distance of x from 4 on the number line can be 5 units in either direction, giving x = 9 or x = -1.
What is algebra?
Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas.
An absolute value equation is of the form |x| = a, where "a" is a positive number. The absolute value of a number is always non-negative, so the equation |x| = a has two possible solutions, x = a and x = -a.
However, there are three possible cases for how many solutions an absolute value equation could have:
One solution: This occurs when a=0. The only solution is x=0 because |0|=0.
Two solutions: This occurs when a > 0. The two possible solutions are x = a and x = -a, since |a| = a and |-a| = a. For example, the equation |x-3| = 2 has two solutions: x-3 = 2 or x-3 = -2, which gives x = 5 or x = 1.
No solutions: This occurs when a < 0. Since the absolute value of a number is always non-negative, an absolute value equation with a negative number on the right-hand side has no solutions. For example, the equation |x-3| = -2 has no solutions since -2 is negative.
The difference in the number of solutions is due to the nature of absolute values. The absolute value of a number represents the distance of the number from zero on the number line, so an absolute value equation can have two solutions when the distance is equal to a positive number, one solution when the distance is equal to zero, and no solution when the distance is less than zero.
For example, consider the equation |x-4| = 5. This equation has two solutions since the distance of x from 4 on the number line can be 5 units in either direction, giving x = 9 or x = -1.

Answer: Absolute value equations are important in situations where values cannot be negative, like measuring distance. For example, if you forget which floor your friend lives on and he tells you he's on the fourth floor, and you say you're two floors away, you could be on either the second or sixth floor. Absolute value inequalities are important in determining margins of error or tolerance, especially in manufacturing.
Step-by-step explanation:
When solving an absolute value equation, three possible scenarios could occur. The first scenario is when the absolute value expression equals a positive number. In this case, there will be two solutions, one positive and one negative. The second scenario is when the absolute value expression equals zero. In this case, there will be only one solution, which is zero. The third and final scenario is when the absolute value expression equals a negative number. In this case, there are no solutions, as the absolute value of any number is always non-negative.
The reason there are differences in the number of solutions for each case is due to the nature of absolute value. Absolute value always returns a non-negative value, regardless of the sign of the number inside the absolute value expression. Therefore, when the absolute value expression is positive, there are two possible solutions, one positive and one negative. When the expression equals zero, there is only one solution, which is zero. And when the expression is negative, there are no solutions, as there cannot be a negative absolute value.
What is the volume of the solid figure?
Answers
Answer:
[tex]625 \: {in}^{3} [/tex]
Step-by-step explanation:
This figure is formed from a cube and a rectangular prism
First, we can find the volume of the cube:
(l (side length) = 5 in)
[tex]v(cube) = {l}^{3 } = {5}^{3} = 125 \: {in}^{3} [/tex]
Now, let's find the volume of the rectangular prism:
(h = 5 in; a (base area) = 20 × 5 = 100 in^2)
[tex]v(prism) = a(base) \times h[/tex]
[tex]v(prism) = 100 \times 5 = 500 \: {in}^{3} [/tex]
In order to find the total volume of this figure, we have to add these two volumes together:

The estimated number of students on the A honor roll who are 8th graders is 126.
What is Algebra?Algebra is a branch of mathematics that deals with symbols and the rules for manipulating these symbols. It involves using letters and other symbols to represent numbers and quantities in equations and formulas.
The main goal of algebra is to find the value of an unknown quantity, called a variable, by using known quantities and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. Algebraic expressions can be solved using various techniques, including simplification, factoring, and solving equations.
The total number of students on the A honor roll is given by adding the number of students in each grade:
Total = 15 (6th grade) + 11 (7th grade) + 14 (8th grade) = 40
To find the proportion of students who are in 8th grade, we can divide the number of 8th graders by the total number of students:
Proportion of 8th graders = 14/40 = 0.35
To estimate the number of students on the A honor roll who are 8th graders, we can multiply the proportion of 8th graders by the total number of students on the A honor roll:
Estimated number of 8th graders = 0.35 x 360 = 126
Therefore, the estimated number of students on the A honor roll who are 8th graders is 126.

Neil is creating a computer game in which bubbles represented by circles collide, merge, and separate in different ways. A bubble with a radius of 8 centimeters separates into small bubbles, each of which has a radius of 2 centimeters. The area of the large bubble is equal to the sum of the areas of the small bubbles. How many small bubbles are there?
Answers
There will be 16 small circular bubbles.
What is circle?A circle is a shape formed by all points in a plane that are at a particular distance from the centre. It is the curve sketched out by a point moving in a plane so that its distance from a given point remains constant. The radius is the distance between any two points on a circle and the centre.
The area of a circle is given by the formula A = πr², where A is the area and r is the radius.
The area of the large bubble is A = π(8cm)² = 64π cm².
The area of a small bubble is A = π(2cm)² = 4π cm².
Let's assume that the number of small bubbles is n. Then, the total area of the small bubbles is n times the area of a single small bubble:
n(4π) = 4nπ cm²
According to the problem, the area of the large bubble is equal to the sum of the areas of the small bubbles:
64π = 4nπ
Dividing both sides by 4π, we get:
n = 16
Therefore, there are 16 small bubbles.

One of my friends wanted to host a dinner party at her house, and she asked me to help her plan the menu. She told me that she was expecting around 10 guests, and she wanted to make sure that she had enough food for everyone. The difficult part was that she had a limited budget and wanted to keep the cost of ingredients low.
Mathematical approach:
To help my friend plan the menu, I used math to estimate the amount of food we needed to buy. I researched online to find the average portion sizes for the dishes we were planning to serve and calculated the total amount of ingredients needed based on the number of guests. Then, I compared the cost of the ingredients at different grocery stores to find the best deals and estimated the total cost of the meal.
Outcome:
By using math, we were able to plan a menu that was within my friend's budget and had enough food for all the guests. We were also able to find the best deals on ingredients, which helped us save money.
Approach for next time:
Next time, I would try to involve my friend more in the mathematical calculations to make sure she understands how to plan a meal within her budget. I would also consider making a list of alternative dishes that we could serve in case we were unable to find a certain ingredient or if it was too expensive.

Answers
The point-slope form of the equation that represents the data set is y - 56 = -5(x - 6), or y = -5x + 86.
EquationsWe are given two points: (6,56) and (12,26) from the data set. We can use the point-slope form of a linear equation to find an equation that represents the data set.
y - y1 = m(x - x1)
where (x1, y1) is a point on the line and m is the slope of the line.
To find the slope, we use the two given points:
m = (y2 - y1) / (x2 - x1)
m = (26 - 56) / (12 - 6)
m = -30 / 6
m = -5
Now that we have the slope, we can use one of the given points, say (6, 56), to write the point-slope equation:
y - y1 = m(x - x1)
y - 56 = -5(x - 6)
y - 56 = -5x + 30
y = -5x + 86

Two functions are given below: f(x) and h(x). State the axis of symmetry for each function and explain how to find it.
Answers
The axis of symmetry for f(x) is x = 1 and h(x) is x=3.
What is axis of symmetry?The axis of symmetry is an imaginary straight line that divides a shape into two identical parts, thereby creating one part as the mirror image of the other part. When folded along the axis of the symmetry, the two parts get superimposed. The straight line is called the line of symmetry/the mirror line. This line can be vertical, horizontal, or slanting.
Equation:Assuming that f(x) and h(x) are quadratic functions, here's how to find the axis of symmetry for each function:
f(x) = 2x² - 4x + 1
To find the axis of symmetry for f(x), we first identify the coefficients a, b, and c:
a = 2, b = -4, c = 1
Then, we use the formula:
x = -b / (2a) = -(-4) / (2 * 2) = 1
Therefore, the axis of symmetry for f(x) is x = 1. This means that the graph of f(x) is symmetric with respect to the vertical line x = 1.
h(x) = -x² + 6x - 5
To find the axis of symmetry for h(x), we first identify the coefficients a, b, and c:
a = -1, b = 6, c = -5
Then, we use the formula:
x = -b / (2a) = -6 / (2 * -1) = 3
Therefore, the axis of symmetry for h(x) is x = 3. This means that the graph of h(x) is symmetric with respect to the vertical line x = 3.

Using a standard deck of cards, a gamer drew one card and recorded its value. They continued this for a total of 100 draws. The table shows the frequency of each card drawn.
Card A 2 3 4 5 6 7 8 9 10 J Q K
Frequency 4 7 5 6 7 6 8 10 7 10 8 12 10
Based on the table, what is the experimental probability that the card selected was a K or 6?
one over 26
four over 25
one fourth
8 over 13
Answers
The experimental probability that the card selected was a K or 6 is [tex]3/20[/tex].
The answer is "three over twenty."
What is probability?The frequency of K and 6 in the table are 8 and 7 respectively. Therefore, the total number of times a K or 6 was drawn is [tex]8 + 7 = 15[/tex].
The total number of draws was 100, so the probability of drawing a K or 6 on any one draw is:
Probability of K or 6 =[tex](Frequency of K + Frequency of 6) / Total number of draws[/tex]
[tex]= (8 + 7) / 100\\= 15 / 100\\= 3 / 20[/tex]
So the experimental probability that the card selected was a K or 6 is [tex]3/20[/tex].
Therefore, the answer is "three over twenty."

-2/3w=12 solve for w
Answers
-2/3w=12
We can start by multiplying both sides by the reciprocal of -2/3, which is -3/2.
-3/2 * (-2/3)w = -3/2 * 12
w = -18
Therefore, the solution to the equation -2/3w=12 is w = -18.
(6.EE.5) Select the equation where x=3
is a solution.
Answers
Answer: x-3=0
Step-by-step explanation: With the equation it is basic algebra. So right now the equation is x-3=0. You will go plus 3, plus 3 on both sides. That would get rid of your negative 3 and make your 0, 3. So what you should have left is, x=3.
