Plz help thanks no links You work on a problem calculating either area or volume. Your answer is 210 ft3. Did you work on an area or volume problem?

THANKS DADDY :)

Step-by-step explanation:

A volume problem.

Step-by-step explanation:

An area problem would be 210 ft2 because you multiply two numbers but with volume you multiply three.

Have a wonderful day! :)

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
