Answer:
or 
Step-by-step explanation:
Given:
A semicircle.
To find:
Arc length of the semicircle = ?
Solution:
Formula for angle subtended by an arc on the center of circle is given as:

where
is the arc length and
is the radius of semicircle.
Angle of full circle is 
So, angle of semicircle = 
Using the formula, we can see that:


So, the answer is:
Arc Length of semicircle =

He can split his pop into in whole mLs any n glasses such that n is a divisor of 30, namely any n in {1,2,3,5,6,10,15,30}. The fraction in each glass is then 1/n.
Answer:
(x + 2) (x + 1) thus b: is the Answer
Step-by-step explanation:
Factor the following:
x^2 + 3 x + 2
The factors of 2 that sum to 3 are 2 and 1. So, x^2 + 3 x + 2 = (x + 2) (x + 1):
Answer: (x + 2) (x + 1)
Goes right 7 and down 8
Answer: b
The first thing we are going to do for this case is define variables.
We have then:
x: number of days
y: number of pages remaining.
We write the linear equation that models the problem:

The intersection with the vertical axis is:
We evaluate x = 0:

We get the point:

The intersection with the horizontal axis is:
We evaluate y = 0:


We get the point:
