There are 20 kids total in the class.

Step-by-step explanation:

15/100 × 20 = 3

You can use direct proportion for any percent calculation.

Compare each number with its percent.

3 i s 15 % of what number? Let the number be x

So, 3 represents 15 % and x represents 100 %

x/ 100 = 3/15

Multiply by 100 to isolate x

x = $\frac{3 x 100}{15}$

x = 20

Check: 15/ 100 × 20 = 3

If y varies inversely with the square of x, and y = 26 when x = 4, find y when x = 2.

eduard

Answer:

D. 104

Step-by-step explanation:

$y \: \alpha \: \frac{1}{ {x}^{2} } \\ \\ y = \frac{k}{ {x}^{2} }$

when y is 26, x is 4:

$26 = \frac{k}{ {(4)}^{2} } \\ k = 416$

when x is 2:

$y = \frac{416}{ {x}^{2} } \\ \\ y = \frac{416}{ {(2)}^{2} } \\ y = 104$
