Set (2.5x+8) equal to (3.5x-7) since they are congruent
Evaluate to find that x=15
Plug 15 in for x: 2.5(15)+8 = 45.5
Remember all angles must add up to 180 degrees
45.5 (F or C) + 90 (A or D) = 135.5
180 - 135.5 = 44.5
44.5 is your answer!

Anna plans to retire at 70 and hopes to withdraw $30,000 per gear until she’s 95. If money earns 6% compounded annually how much will she need at 70
Answers
Answer:
$383,500.68
Step-by-step explanation:
The amount needed is the present value of the $30,000 that Anna will withdraw for 25 years compounded at 6% annually
=pv(rate,nper,pmt,fv)
rate is the annual rate of 6%
nper is the number of years of withdrawal which is 95-70=25
pmt is the amount of annual withdrawal which is $30,000
fv is the amount of withdrawals which is unknown
=pv(6%,25,-30000,0)=$383,500.68
The amount of she required at 70 is $$383,500.68 which gives her the benefit of withdrawing $30,000 per year at retirement
A furniture company is introducing a new line of lounge chairs next quarter. These are the cost and revenue functions, where x represents the number of chairs to be manufactured and sold: R(x) = 1,248x – 8.32x2 C(x) = 36,400 – 83.2x
Answers
The profit function for a furniture company introducing a new line of lounge chairs is P(x) =\(-8.32x^2 + 1,248x - 36,400\), where x represents the number of chairs to be manufactured and sold.
The problem provides the revenue function and cost function for a furniture company introducing a new line of lounge chairs. To find the profit function, we need to subtract the cost function from the revenue function.
The revenue function R(x) is given as 1,248x - \(8.32x^2\), where x represents the number of chairs manufactured and sold. This function calculates the total revenue obtained by the company by multiplying the number of chairs sold (x) by the price of each chair (1,248 - 8.32x).
The cost function C(x) is given as 36,400 - 83.2x. This function calculates the total cost incurred by the company to manufacture x chairs, which includes both fixed and variable costs.
To find the profit function for the furniture company, we need to subtract the cost function C(x) from the revenue function R(x):
P(x) = R(x) - C(x) = (1,248x - \(8.32x^2\)) - (36,400 - 83.2x)
Simplifying this expression, we get:
P(x) =\(-8.32x^2\) + 1,248x - 36,400
Therefore, the profit function for the furniture company is P(x) = \(-8.32x^2\) \(+ 1,248x - 36,400\).

Find the equation of the line that satisfies the conditions given in each of the following: 1. Through (3, 2) and (5, 7) 2. Through (-3, 4), m = 2 3. m = -3, b = 5 4. x-intercept = 3, y-intercept
Answers
The equation of each line that satisfies the given conditions are:
1. y - 2 = 5/2(x - 3)
2. y - 4 = m(x + 3)
3. y = -3x + 5
What is the Equation of a Line?If we know the slope (m) and the y-intercept (b) of a line, we can write the equation of the line as y = mx + b in slope-intercept form.If we know the point (a, b) and the slope (m) of the line, we can write the equation of the line in point-slope form as y - b = m(x - a).1. Given the points, (3, 2) and (5, 7), find the slope (m):
Slope (m) = change in y / change in x = (7 - 2)/(5 - 3)
m = 5/2
Write the equation in point-slope form by substituting m = 5/2 and (a, b) = (3, 2) into y - b = m(x - a):
y - 2 = 5/2(x - 3)
2. Given:
A point = (-3, 4)
Slope (m) = 2
Substitute (a, b) (-3, 4), and m = 2 into y - b = m(x - a):
y - 4 = m(x + 3) [equation of the line]
3. Given:
Slope (m) = -3

levi had an uber ride of $19.95 if there was a tip of 20% what is the amount of the tip
Answers
Levi pays $3.99 for her ride as per the values given in the problem.
What is percentage?A percentage is a value that indicates 100th part of any quantity. A percentage can be converted into a fraction or a decimal by dividing it by 100. In the same manner a fraction being multiplied by 100 becomes percent.
The charge for the uber ride is given as $19.95.
And, the percent value of the tip is 20%.
Now, the amount of tip can be calculated by taking the percent value of the total charge as follows,
20% × Uber charge for ride
⇒ 20% × 19.95
⇒ 20/100 × 19.95
⇒ 3.99
Hence, the required money to be paid by Levi is given as $3.99.

Answers
The incorrect statement is:
B. The three-part inequality - 5x < 15x^2 < 3 is equivalent to - 6 ≤ 5 - x < 6.
In the given statement, there is an error in the inequality. The correct statement should be:
The three-part inequality - 5x < 15x^2 < 3 is equivalent to - 6 ≤ 5 - x and 5 - x < 6.
When solving the three-part inequality - 5x < 15x^2 < 3, we need to split it into two separate inequalities. The correct splitting should be:
- 5x < 15x^2 and 15x^2 < 3
Simplifying the first inequality:
- 5x < 15x^2
Dividing by x (assuming x ≠ 0), we need to reverse the inequality sign:
- 5 < 15x
Simplifying the second inequality:
15x^2 < 3
Dividing by 15, we get:
x^2 < 1/5
Taking the square root (assuming x ≥ 0), we have two cases:
x < 1/√5 and -x < 1/√5
Combining these inequalities, we get:
- 5 < 15x and x < 1/√5 and -x < 1/√5
Therefore, the correct statement is that the three-part inequality - 5x < 15x^2 < 3 is equivalent to - 6 ≤ 5 - x and 5 - x < 6, not - 6 ≤ 5 - x < 6 as stated in option B.

what is the property of 3x(5x7)=(3x5)7
Answers
The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.
In the equation you provided: 3x(5x7) = (3x5)7
The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

Answer:
A
Step-by-step explanation:
To answer this question, we can use the following co-function identity:
\(\sin(\theta)=\cos(90\textdegree-\theta)\)
We know that sin(21°) is 0.36. This means that:
\(0.36=\sin(21\textdegree)=\cos(90\textdegree-21\textdegree)\)
Subtract within the cosine:
\(0.36=\sin(21\textdegree)=\cos(69\textdegree)\)
We can remove our second term:
\(\cos(69\textdegree)=0.36\)
So, our answer is A.
