A tree grow 1/4 foot in 1/12 year.

lilavasa [31]

Answer:

Part A) The rate is $\frac{12}{4}\ \frac{feet}{years}$

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

$\frac{(1/4)}{(1/12)}=\frac{12}{4}\ \frac{feet}{years}$

Part B) how many feet does the tree grow in 1 year?

we know that

The tree grows at rate of $\frac{12}{4}\ \frac{feet}{years}$

Simplify

$\frac{3}{1}\ \frac{feet}{year}$

That means ----> The tree grows 3 ft in 1 year

therefore

In 1 year the tree grows 3 feet

What is the difference between the largest prime number less than 5o and the smallest comoosite number greater than 10

erastova [34]

<h3>Answer: 35</h3>

A prime number is one where the only factors are one and itself. A composite number has other factors.

You'll have to look at the list of numbers from 1 to 50

In that list, 47 is the largest prime less than 50, and 12 is the smallest composite number greater than 10.

So 47-12 = 35
