A circular mirror has a circumference of 507 inches. What is the radius of the mirror? Show your work.

80.7 inches

Step-by-step explanation:

circumference = 2 * pi * r

2 * pi * r = 507 inches

r = (507 inches)/(2 * pi)

r = (507 inches)/(2 * 3.14159)

r = (507 inches)/(6.2832)

r = 80.7 inches

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
