HURRY! PLEASE HELP

3. What methods are you using to test this (or each) hypothesis?

To test this theory I used balls and measured their mass, volume, density, and the amount of displaced water or how much a tube would be filled up if the ball was placed inside.

For Example:

In the experiment where I used Table B, I filled a bucket up with water and predicted whether or not an inflated football would float if I put it in the water, then I measured the amount of displaced water from putting the inflated football in the bucket, which was 4000 mL. Then I did the exact same thing but with a deflated football, the amount of displaced water was 500 mL.

Explanation: This is the answer I put on edg

the total distance traveled by the car is

30km + 49km = 79 km .
