Answer with Solution. (box the final answer) 1. The amount of paint p Formulas: p k = A/p = kA needed to paint the wall of Mini Park (VNHS) varies directly as the area A of the wall. If 2 gallons of paint is needed to paint a 40 sq meter wall, how many gallons of paint are needed to paint a wall with an area of 100 square meters?

ACTIVITY 4: Solve the given problem below. Answer with Solution. (box the final answer) 1. The amount of paint kA ; k= A/p Formulas: p = needed to paint the wall of Mini Park (VNHS) varies directly as the area A of the wall. If 2 gallons of paint is needed to paint a 40 sq meter wall, how many gallons of paint are needed to paint a wall with an area of 100 square meters? Answer with Solution. (box the final answer) Formulas: d = k/m; k= dm 2. The number of days d repair (VNHS) inversely as the number men m working. It takes 15 days for 2 men to repair the garden. How many men are to complete the job needed to Math Garden varies of needed for 6 days? Answer with Solution. (box the final answer) Formulas: F = km/d? ; k= Fd² / m 3. The force of attraction, F of a body varies directly as and inversely its mass m as the square of the distance d from the body. When 8 kg and d = 5 meters, m F = 100 Newton. Find F when m = 2 kg and d 15 meters.
