Answer:
Each shade has a 22.5 degree angle from the middle
Each unshaded has a 67.5 degree angle from the middle.
Step-by-step explanation:
You can solve this by making each unshaded part equal to x and each shaded part equal 1/3x it is a circle so it has to equal 360 so you end up with:
x + 1/3x + x + 1/3x + x + 1/3x + x + 1/3x = 360
Combine Like terms:
16/3x = 360
Multiply both sides by the opposite:
(3/16) (16/3x) = (360) (3/16)
x=135/2 or x=67.5
Then you can plug 67.5 in for x:
1/3x ---> 1/3(67.5) = 22.5
Answer:
Nick has to work 8 hours
Step-by-step explanation:
Nick makes 9 works x
Julia makes 12 works 6
first find out how much Julia makes you can do that by multiplying 12 by 6 witch = 72
and we know we are trying to find how many hours Nick needs to work to equal Julia so we knew they are equal
so we have 9X=72
we just have to solve...
divide 72 by 9
leaving use with X=8
