Hi there!

Your question asks of a whale's elevation after 6 seconds.

To find that, we must first find how much the whale descents per second. To do that we divide 382.5 feet on 45 seconds.

The answer to that will be 8.5 feet.

8.5 feet is how much a whale will descend per second. To see how much it will descend in 6 seconds, we multiply 8.5 on 6, and that will equal 51 feet.

Your answer is 51 feet.

Hope this helped!~

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

answer4 to the second power is 16

and 4 to the third power is 64,
