Answer:
Part A) The rate is [tex]\frac{12}{4}\ \frac{feet}{years}[/tex]
Part B) In 1 year the tree grows 3 feet
Step-by-step explanation:
Part A) write the rate at which this tree grows as a fractions
we know that
To find out the rate at which the tree grows divide 1/4 foot by 1/12 year
so
[tex]\frac{(1/4)}{(1/12)}=\frac{12}{4}\ \frac{feet}{years}[/tex]
Part B) how many feet does the tree grow in 1 year?
we know that
The tree grows at rate of [tex]\frac{12}{4}\ \frac{feet}{years}[/tex]
Simplify
[tex]\frac{3}{1}\ \frac{feet}{year}[/tex]
That means ----> The tree grows 3 ft in 1 year
therefore
In 1 year the tree grows 3 feet
