Asunflower was 20 1/2 inches tall. over the next 6 months, it grew to a height of 37 inches tall. what was the average yearly growth rate of the height of the plzzz write a proportion i will give you 100 points

  33 inches per year

Step-by-step explanation:

In half a year, the sunflower grew 37 -20 1/2 = 16 1/2 inches. Your proportion is ...

  (16 1/2 inches)/(1/2 year) = g/(1 year) . . . . . . . where g is the yearly growth

Multiplying by 1 year and simplifying, you can find g to be

  g = (33/2 inches)/(1/2) = 33 inches

That is, the growth rate is 33 inches per year.

Comment on the solution technique

I personally find a proportion to be unnecessary. When you want to find the rate of x per y, divide the amount of x you are given by the amount of y you are given.

Here, you are given a growth of 16 1/2 inches in 1/2 year, so you simply perform the division (16 1/2 inches)/(1/2 year) = 33 inches/year.

(x+3)(x+7)
