The volume of a box (v) varies directly with its length (l). if one of the boxes has a volume of 288 cubic inches and a length of 12 inches, what is the constant proportionality for the group of boxes

ANSWER

The constant of proportionality is 24.

EXPLANATION

If the volume of a box (V) varies directly with it's length (l), then we can write the mathematical statement,



We introduce the constant of proportionality k, and write the equation,



When V=288, l=12.

We substitute these values to obtain;



Divide both sides by 12,

24

Step-by-step explanation: got it righ

The slope is rise over run. The ski run drops 5, so it would be -5, and the horizontal change of 20 would be the run, so you'd get -5 over 20 then you divide both by 5 and you get your answer of -1 over 4.
