The volume of paint used, V liters, is directly proportional to the area, A square feet, that the paint can cover. 5 liters of paint can cover a wall with an area of 75 square feet.

Question Completion

a) Find the constant of proportionality.

b) Write an equation relating V and A.

c) How much paint would be needed to cover an area of 180 square feet?

(c)12 Liters

Step-by-step explanation:

The volume of paint used, V liters, is directly proportional to the area, A square feet, that the paint can cover.

This is written as:

(a)5 liters of paint can cover a wall with an area of 75 square feet.

V=5 liters, A=75 square feet.

Substitution into V=kA

5=75k

k=5/75

(b)Substitution of into V=kA

The equation relating V and A is:

(c)If A=180 Square feet

Volume of paint needed,

what? that isnt a question

step-by-step explanation:

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
