<span>The arc length in degrees (same as central angle that cuts it off) is to 360 (degrees in a circle) AS the arc length in linear measure is to the circumference of the circle (2 pi r).
90/360 = AL/[2 pi (85)] where AL is the arc length in linear measure.
1/4 = AL/[170 pi]
4 AL = 170 pi
AL = 42.5 pi
AL = 133.45 feet (approx)
I hope your satisfied with my answer in feel free to ask for more

Answer:
x = 20/32
Step-by-step explanation:
you have to distribute first.
1) times 4 by all the nubmers and figures inside the pharanthesese and so you get 32x + 20
2) you have to solve for x and so you move the 20 to the other side and get 32x = 20
3) you then divided both sides by 32 to get x by itself and you get x = 20/32
Answer:
E: x = 13
F: x = 1.5 or 3/2
Step-by-step explanation:
This is for E:
x + 2/3 = 5
All you do is first multiply 5 * 3
and you will get 15
x + 2 = 15
Then you subtract from 15
15 - 2 = 13
So x = 13
This is for F:
10(x - 1) = 5
So all you do is distribute the 100 with x -1
10 * x = 100x
10 * -1 = 100
10x - 10 = 5
Then you add 10 to 15 because the number is -10
5 + 10 = 15
10x = 15
Now you divide by 10 on both sides
10x/10 = 15/10
10x/10 = x
15/10 = 3/2
So the answer for F is 3/2 or 1.5
21.78, take and multiply 2.79 by 5 ( there are 5 week days), and add the 7.83 once because it is the price for the two coffees. So weekly he spends roughly 21.78 on coffees
