120:100 or 6:5 so 24:x
if ratios are the same then the reciprocal of one of the ratios times the other ratio should equal 1 so 6/5 times x/24=1
6x/120, x=20

Answer:

G

Explanation:

k =  \frac{5}{9} (f + 460) \\ when \: f =  - 10 \\ k =  \frac{5}{9} ( - 10 + 460) \\ k =  \frac{5}{9} (450) \\ k = 250

19. 4/6 or 2/3 (lowest term) or 2:3 in ratio
20. 2/3 or 2:3 in ratio
21. 5/12 or 5:12 in ratio
22. 14
    To get geometric mean, multiply the numbers then get the square root of the product (if there are two numbers), cube root (if there are three numbers), and so on. In this case, 7*28 = 196; √196 = 14
23. 10 ft : 2.5 ft.
    Convert the values so that it will be similar. In this case, 30 inches is converted to ft.
24. 24 is the Perimeter of ABCDE.
    ABCDE and FGHJK are similar shapes. Similar shapes have proportional measurements.

Now compute for the sides of ABCDE.
AB = 4; BC = ?; CD = ?; DE = ?; EA = ?
AB + BC + CD + DE + EA
4 + 4 + 5 + 6 + 5 = 24

Find BC:
AB/BC = FG/GH
   4/BC = 8/8 
    8BC = 32
      BC = 4

Find CD:
BC/CD = GH/HJ
   4/CD = 8/10
    8CD = 40
      CD = 5

Find DE:
CD/DE = HJ/JK
   5/DE = 10/12
  10DE = 60
       DE = 6

Find EA
DE/EA = JK/KF
   6/EA = 12/10
  12EA = 60
      EA = 5

He should receive around $21.88. This is excluding the fact he still needs to pay the sales tax. I would subtract a few more dollars.
