Tim planted a tree that was 36 in tall. the tree grew 3/4 in per year. that tree is now 43 1/2 in tall. how many years ago did tim plant the tree

The tree was planted 11 years ago.

Step-by-step explanation:

This is an example of arithmetic progression.

First term, a = 36 inch.

Common difference, d = 3/4 = 0.75 inches.

We have equation for n th term = a + (n-1)d

That tree is now 43 1/2 in tall

That is

               43.5 = a + (n-1)d = 36 + (n-1) x 0.75

               (n-1) x 0.75 = 7.5

                 n - 1 = 10

                 n = 11

The tree was planted 11 years ago.

step-by-step explanation:

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.
