The equations are e = 18+12t and a = 45+9t
Adrian will be father along in the book after 4 days. She will be 15 pages ahead of Ethan
Ethan's page number at the beginning of the month = 18
Adrian's page number at the beginning of the month = 45
Pages read by Ethan each day = 12 pages
Pages read by Adrian each day = 9 pages
Let e represent the page of the book that Ethan is on at the end of t days into the month. Let a represent the page of the book that Adrian is on at the end of t days into the month.
Formulating the equation we get the following:
e = 18 + 12t
a = 45 + 9t
Finding the page number of both Ethan and Adrian after 4 days by substituting the values in the equations we get:
e = 18+12(4)
e = 66
a = 45 + 9(4)
a = 81

The number of athletes that finished the race this year was 4284 athletes.
What is percentage?
10%, a comparative figure denoting one hundredth of any quantity. One percent, denoted by the symbol 1%, is equal to one hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified.
Let x represent the amount of athletes that finished the race this year.
Last year, 3,570 athletes finished the Silvergrove Marathon. This year, the number of runners crossing the finish line was 20% higher. Hence:
x = 3570 + 20% of (3570)
x = 3570 + (0.2 * 3570)
x = 4284
4284 athletes finished the race.

Answer:
Step-by-step explanation:
Like prisms, the volume is found by multiplying the area of one end of the cylinder (base) by its height.
Since the end (base) of a cylinder is a circle, the area of that circle is given by the formula:
area =πr^2
Multiplying by the height h we get
volume =πr^2h
where:
π is Pi, approximately 3.142
r is the radius of the circular end of the cylinder
h height of the cylinder
The answer is 8.
Explanation:
To find this out we would first subtract the width (1.6) from the length (14.4). 14.4 - 1.6 = 12.8. If we want to find out how many times which is how many time 1.6 to get 12.8, we would divide 12.8 by 1.6. The quotient is 8. Therefore, the length of the rectangle is 8 times that of the width.
