Hello!

To solve this you have to find the ratio between the two cylinders

Cylinder 1 height is 30
Cylinder 2 height is 20

this is a 30:20 ratio

This can be reduced to a 3:2 ratio

Now you look for one that are also equal to 3:2

3 * 7 = 21
2 * 7 = 14

The answers are 3:2 and 21:14

Hope this helps!

Answer:

8 ft

Step-by-step explanation:

the ladder will make a right angle triangle with the house. The hypotenuse of the triangle is the ladder, 20 ft, and the height of the triagnle is 18 ft.

Solve for the base of the right angle triangle using pythagorean's theorem:

c=20, a=18, b=?

$b^{2}=c^{2} - a^{2}\\b^{2}=20^{2} - 18^{2}$

$b=\sqrt{72}$

$b= 8.49 ft$

round to the nearest foot,

b = 8 ft

1) What part of 20 is 5?<br> 2) What part of 20 is 12?

Ksivusya [100]

Answer:

Step-by-step explanation:

You find the part by expressing the ratio as a fraction, then simplifying.

1. 5/20 = (1·5)/(4·5) = (1/4)·(5/5) = 1/4

5 is 1/4 of 20.

2. 12/20 = (3·4)/(5·4) = (3/5)·(4/4) = 3/5

12 is 3/5 of 20.
