There were two trees growing seeds in a backyard. one tree grew at a rate of 1/2 a foot every 2 years. the other grew 4 inches every 3 years. in 12 years, what will the difference between the heights of the two trees be in inches? ? plzz i will give you 299 points

20 in  

Step-by-step explanation:

Tree 1:

Rate of growth = (½ ft/2 yr)

  12 yr growth = 12 × (½/2)

                       = 6/2

                       = 3 ft

                       = 36 in

Tree 2:

Rate of growth = (4 in/3yr)

  12 yr growth = 12 × (4/3)

                       = 48/3

                       = 16 in

Difference:

Tree 1 - Tree 2 = 36 - 16

                            = 20 in

The trees will differ in height by 20 in.

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
