Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a radius of 2 feet and a height of 16 feet. Container B has a radius of 4 feet and a height of 4 feet. Container A is full of water and the water is pumped into Container B until Containter B is completely full. To the nearest tenth, what is the percent of Container A that is full after the pumping is complete?

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
