Question 4
Archie and his friends went scuba diving. Each person recorded his dive depth. If land represents 0, which dive depth is closest to the surface of the water?

-20 feet

Step-by-step explanation:

You have to look at it as negative but we aren’t allowed to look at distance as negative. So the closer to zero below water the greater it is. That means 20 feet is the greatest or closest to zero.

a - base

b - exponent

so,

ratio is 2 : 9

the answer is three

13.5 : 3
