Answer:

Sophia's time was either 6 above or 14 below the average

Step-by-step explanation:

We know two things about the time:

1. Jacob was 4 mins below average

2. Sophia was 10 minutes different than Jacob

We don't know if she was quicker or slower, however. So we can work out both.

We can take Jacob's time as -4 since he was 4 BELOW the average. If we take -4+10 this would represent if Sophia was faster than Jacob.

-4+10=6.

Now the other way. -4-10=-14.

ASAP! Please help me with this question!

Answer:

24 cm

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

2304 pi = 4/3 pi r^3

Divide each side by pi

2304 = 4/3 r^3

Multiply each side 3/4

2304 * 3/4 = 4/3 r^3 * 3/4

1728 = r^3

Take the cube root of each side

1728 ^ 1/3 = r^3 ^ 1/3

12 = r

We want the diameter

d = 2*r

d = 2*12

d = 24

Whats an equation that make x=31 ? like in other words give me an equation where it leads down to 31
MrRa [10]
Sure, that's easy! Here's one

5x + 7 = 162

If I wanted to solve this equation, I would break it down. I'd subtract the result (162) by 7

162 - 7 = 155.

From there I just divide that by 5!

155 / 5 = 31

There it is! Ultimate proof that x is in fact 31!
