Answer:

\displaystyle \frac{a^2 }{b^2}=\frac{4}{9}

\displaystyle \frac{a}{b}=\frac{2}{3}

\displaystyle \frac{a^3}{b^3}=\frac{8}{27}

Step-by-step explanation:

<u>Ratios and Proportions </u>

The ratio between two numbers x and y is defined as x/y. It measures how many times y is contained in x. For example 12/8 = 1.5 means 12 is 1.5 times 8.

We have two key sets of data: the ratio between the surface areas of the cylinders and the fact that the radius and heights of the cylinders come in the same proportion.

First, we can easily compute the ratio of the surface areas

\displaystyle \frac{Area_1}{Area_2}=\frac{8\pi \ in^2 }{18\pi \ in^2}=\frac{4}{9}

It gives us the relation  

\displaystyle \frac{a^2 }{b^2}=\frac{4}{9}

Computing the square root

\displaystyle \frac{a}{b}=\frac{2}{3}

Computing the cube

\displaystyle \frac{a^3}{b^3}=\frac{8}{27}

you borrow $200 from a friend to help pay for a new laptop computer. You pay your friend back $12per week. Write and solve an in
Nadusha1986 [10]
Given:
loan = 200
payment per week = 12
should be less than = 60

12x - 200 < 60 
       

12x - 200 < 60
<u>       +200    +200</u>
12x          < 260
 <u>÷12             ÷12</u>
    x          < 21.67

If x = 20
12x - 200     < 60
12(20) - 200 < 60
240 - 200     < 60
               40 < 60
