Question

The height, hh, of a plant (in inches) ww weeks since it was planted is represented by the equation h=1.2w+3h=1.2w+3. How many weeks ( round up to the nearest whole number) will it take the plant to reach one foot? ( Hint: convert feet to inches.) Answer value

Answer 1

It will take 8 weeks for the plant to reach one foot.

Explanation:

The equation is:

`h = 1.2w + 3`

Where:

h: is the height = 1 foot

w: is the time in weeks =?

We can convert feet to inches as follows:

`1 feet = 12 inches`

`h = 1 ft*(12 in)/(1 ft) = 12 in`

Hence, the number of weeks is:

`w = (h - 3)/(1.2) = (12 - 3)/(1.2) = 7.5 = 8`

Therefore, it will take 8 weeks for the plant to reach one foot.

I hope it helps you!
