Lets say cookies = x and days = y.

2x times y = 15.

8x times y = 45.

Solution:

we are given that

Emma has 15 cookies and eats 2 cookies per day.

So the number of cookies left after n days can be written as

Emma=15-2n

Evan has 45 cookies and eats 8 each day.

So the number of cookies left after n days can be written as

Evan=45-8n

Number of days after which they will have equal number of cookies can be found as below

15-2n=45-8n

8n-2n=45-15

6n=30

n=5

Hence both will have equal number of cookies after 5 days.

The volume of a _________ is equal to ___ the volume of a cylinder that has the same base and height. The formula for the volume
katrin2010 [14]

Answer:

cone, \frac{1}{3} , \frac{1}{3} \pi r^{2}h , \pi r^{2}, base, h, height, same, \frac{1}{3} , \frac{1}{3} , 3

Step-by-step explanation:

The volume of a cone is equal to \frac{1}{3} the volume of a cylinder that has the same base and height. The formula for the volume of a cone is \frac{1}{3}\pi  r^{2}h.  stands for the area of the base and h is the height of the cone. Knowing this, we could quickly find the volume of a cone that has the same base and height as a cylinder with a volume of 9 cubic cm. Since the volume of a cone is \frac{1}{3} the volume of a cylinder (with the same base and height), we would multiply 9*\frac{1}{3} to obtain a volume of 3 cubic cm.
