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

0x-7*9 = 0<br>Solve for x.<br>​
Helga [31]

Answer:

Undefined

<em>Step </em><em>by</em><em> step</em><em> </em><em>explaination:</em>

<em> </em>

by order of operations we know that we multiply first;

so, 0x-(7*9)=0

1) Multiply the ones in brackets first:

0x-63=0

2) To make X the subject perform the opposite operation:

0x-64+63=0+63

0x=63

3) Divide 0 on both sides;

0x/0= 63/0

therefore; <u>x is undefined</u>

Emilio and friends are in a submarine 500 feet below sea level. They continue to dive 35 feet each hour for 7 hours.
katovenus [111]
You would write the equation out as x=35x+500

You substitute x for 7 so it’s x= 35(7)+500

So the answer will be 745 dollars

Find the solution<br> x/5 - 1/5 = x/3 + 1/4
Vilka [71]

Answer:

x = - 27/8

x=-3\frac{3}{8}

Step-by-step explanation:

¹²⁾x/5 - ¹²⁾1/5 = ²⁰⁾x/3 + ¹⁵⁾1/4

12x - 12 = 20x + 15

- 12 - 15 = 20x - 12x

- 27 = 8x

x = - 27/8

x=-3\frac{3}{8}
