A cube has side length 10 inches. Jada says the surface area of the cube is 600 in?, and Noah says the surface area of the cube is 3,600 in. Here is how each of them reasoned:
Jada's Method:
6 102
6 - 100
600
Noah's Method:
6. 102
602
3, 600
Do you agree with either of them? Explain your reasoning.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
