Answer 1

Answer:

Answer:

Perimeter A = 122.5

Step-by-step explanation:

Set up the following proportion

The Perimeter of B = 12 + 9 + 9 + 5

The Perimeter of B = 35

7/2 = x/PerimeterB

7/2 = x / 35 Cross multiply

7*35 = 2x Combine the left side

245 = 2x Divide by 2

245/2 = 2x/2 Do the division

122.5 = x

The Perimeter of A = 122.5

Problem 3

If you compare the sides opposite the angle marked with a single arc, you will get the scale factor.

If these triangles are similar, and one of the sides opposite their markings will give you the scale factor

18/7.2 = x/1 where x is the scale factor going from the larger to the smaller triangle.

2.5 = x

So if you multiply the smaller triangle's sides by 2.5 you get the larger triangle.

a car is purchased for 26,000 after each year the resale decrease by 35% what will the resale value be

Answers

26,500 * .25 = 6625
26,500 - 6625 = $19875 ---------> Price after 1 year

Price after 2 years:
19875 * .25 = 4968.75
19875 - 4968.75 = $14,906.3 ---------> Price after 2 years

Price after 3 years:
14,906.3 * .25 = 3726.58
14,906.3 - 3725.58 = $11,179.7 ----------> Price after 3 years

Price after 4 years:
11,179.7 * .25 = 2794.93
11,179.7 - 2794.93 = $8384.77 ------> Price after 4 years, rounded to the nearest dollar = $8385

26,000 * 35% = 910. So $910 would be subtracted from 26,000 for each year
