An inverted conical tank starts the day with 250 ft^3 of crayon wax in it. As the factory commences work the tank is filled with an additional 40 ft^3 of wax per minute. The height of the wax in the tank is modeled by H(V)= 3piV/25. A. Write a function V(t) to model the volume of wax in the tank after t minutes. B. Find an expression for the composition (HoV)(t) C. The composition in B. can be described as the of the wax in terms of .

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.

good luck on ur quiz test or homework. have a good day : )

$25 becasue a 10 increase would make it from 80 to 50
