Answer:
Step-by-step explanation:
Use the formula 
to find the sum of the angles in a polygon, given <em>n</em> sides. This formula tells us the angles of this pentagon must add to 540 (
).
So, we can setup an equation:
Solve for z:
Combine like terms
Subtract 200
Divide by 5
Therefore, the value of z = 68.
The answer is the 3rd one: 7n-2p
Simply the standard deviation of the data values is the square root of the variance:
=18
Answer:
D)18
V=4/3πr^3, so substitute what you know. Input the volume so you only have to solve one variable, the r, radius.
The circumference (perimeter) of the tire is 2 x π x r (radius= half of the diameter):
So one complete rotation is equivalent to the perimeter that is 2 x 13 x 3.1459
= 81.68 inches & if he competed 10 rotation that means he run for 10 x 81.68 ===> 816.8 In
