Big Brothers, Inc. borrows $267,999 from the bank at 18.16 percent per year, compounded annually, to purchase new machinery. This loan is to be repaid in equal annual installments at the end of each year over the next 10 years. How much will each annual payment be?

Round the answer to two decimal places.

Answers

Based on the amount borrowed and the interest per year, Big Brothers, Inc will pay an annual payment of $59,973.15.

How much will Big Brothers, Inc. pay annually?

This can be found by using the present value of an annuity formula because the annual payment will be constant and therefore like an annuity.

Formula is:

Present value of annuity = Annual payment x ( 1 - (1 + rate) ^ -number of periods) / rate

Solving gives:

267,999 = Amount x ( 1 - ( 1 + 18.16%)⁻¹⁰) / 18.16%

267,999 = Amount x 4.46865

Amount = 267,999 / 4.46865

= $59,973.15

We can see there are brackets. When a number is placed near a bracket, it means we need to multiply.

Let's check our expression.

We can see that there is addition and subtraction. When we have addition and subtraction together we can solve left to right. The same applies to multiplication and division.

So let's solve the rest of it.

What are m∠1 and m∠2?

Answers

Answer:

B. <1 = 35, m<2 = 30

Step-by-step explanation:

To figure out m<1 I first need to figure out the other missing angle. A straight line is a 180 degree angle. Taking that information you can do 180 - 115. This means that the missing angle is 65 degrees. The interior angles of triangles always add up to 180.

80 + 65 = 145

180 - 145 = 35

<1 = 35

Repeat with the other side.

85 + 65 = 150

180 - 150 = 30

<2 = 30

What is the solution for x in the equation?

-2x + 14 + 10x = 34

A.

B.

C.

D.

Answers

Answer: 2.5

Step-by-step explanation:

-2x + 14 + 10x = 34

8x + 14 = 34

8x = 34 - 14

8x = 20

x = 20/8

x = 5/2

x = 2.5

Combine the like terms first
14 +8x =34
Subtract 14 both sides
8x = 20
Divide both sides by 8
x = 20/8
Reduce
x= 5/2
x = 2 1/2 or 2.5

The perimeter of a rectangle with length l and width w is 44 inches. The area of the rectangle is at most 120.
Which of the following statements is true?
A. If w 12 inches, then l 10 inches
B. If w 12 inches, then l 10 inches
C. If w 12 inches, then l 10 inches
D. If w 12 inches, then l 10 inches

Answers

The true statement about the rectangle  is A. If w is 12 inches, then l is 10 inches

How to determine the true statement?

The given parameters are:

Perimeter, P = 44Area = 120 (at most)

The perimeter of a rectangle is:

P = 2(L + W)

So, we have:

2(L + W) = 44

Divide by 2

L + W = 22

The area is calculated as:

A = LW

This gives

LW = 120

Express 120 as 12 * 10 and 10 * 12

LW =12 * 10 or LW = 10 * 12

By comparison, we have:

L = 12 and W = 10 or L = 10 and W = 12

When these values are substituted in L + W = 22, we have:

10 + 12 = 22 and 12 + 10 =22

This means that the dimensions of the rectangle are 10 by 12 inches or 12 by 10 inches

Hence, the true statement is A. If w is 12 inches, then l is 10 inches
