144 or 72^2

Step-by-step explanation:

You have one leg a 5 and the other leg we don't know, well we know the hyponuse is a 13.

So the first step is

A^2 + B^2 = C^2

2 step,

5^2 + B^2 = 13^2

3 step

5 x 5 = 25 and 13 x 13 = 169

25 + B^2 = 169

4 step

169 - 25 = 144

144 divided by 2 is 72, so 72 x 72 is 144.

If you have an answer 72 squared or 144 both will work.

It does not help that you don't give the answers.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
