Answer:
feet : Shark is 72 feet below sea level.
Step-by-step explanation:
Let x represent depth of the shark.
We have been given that the submarine’s depth was twice the depth of the shark. This means that depth of submarine would be
.
We have been given that a submarine was 144 feet below sea level, so submarine's elevation would be
.We can represent this information in an equation as:

To find shark's position, we need to solve for x.


Therefore,
feet represents shark's elevation, which represents that shark is 72 feet below sea level.

Answer:
(12/8) and (3/4) = 2 1/4 or 2.25 decimal thus: A:
Step-by-step explanation:
The area would be 25π inches.
Since the cross-section goes through the center of the sphere it will be a circle. The area of a circle is given by A = πr²; for our circle, since the diameter is 10 inches, the radius is 5;
A = π(5²) = 25π
