Peter brought 8 sets of paint. He gives half of his sets to his sister. Each set has 5 bottles. How many bottles does Peter's sister have? Write equations and solve.

20 bottles

Step-by-step explanation: If he gave half to his sister and half of 8 is 4 and each of the 4 sets has 5 bottles then you would multiply 4 x 5 and get 20 bottles

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
