Answer: Option D.
Step-by-step explanation:
By definition, the absolute value of a number is its distance from 0 on a number line. We know that the distances cannot be negative. Then:
We can assume that the water is at level 0.
We know that the diver dove from a diving platform, which is 4 feet above the water, and then she stopped at -8 feet to pick up some scallops.
This indicates that she stopped at 8 feet below the water.
Therefore, in order to find how far below the diving platform the diver is, we must add 4 feet and the absolute value of -8 feet.
Then, the expression that models this situation is:
Notice that it matches with the expression shown in Option D.
ANSWER
The swimming pool can hold 1,000,000 cubic feet of water.
EXPLANATION
The capacity of water the pool holds is the volume of water in the swimming pool.
The swimming pool is rectangular, therefore its volume can be calculated using the formula,
where l=1000ft is the length, w=100ft is the width and h=10ft is the height of the pool.
We substitute all these values into the formula to get:
The swimming pool can hold 1,000,000 cubic feet of water.
