Answer:
40π in^2
Step-by-step explanation:
360°/72°=5
so, each of the two shaded regions are 1/5 of the circle.
the formula for finding the area of a circle is πr^2, so:
area for one of the shaded regions:
1/5πr^2
1/5π(10)^2
1/5π100
20π in^2
this means that the area for one of the shaded regions is 20π. however, since there are two of them:
2(20π)=40π
so, the area of the shaded regions is 40πin^2
You have one of the answers correct. The fraction 4/8 is equal to 1/2
Other answers are: 5/10, 10/20, and 6/12
If you reduced each of those fractions, you'd get to 1/2.
You can use a calculator to find that
4/8 = 0.5
1/2 = 0.5
5/10 = 0.5
10/20 = 0.5
6/12 = 0.5
All fractions mentioned lead to the same decimal value, so this confirms all of the fractions are equivalent to one another.
The pair of points that are equal to x coordinates is (0,0)
Answer:
Cooper made $22.80 per hour.
Step-by-step explanation:
Since Cooper made a total of $228.00 within 10 hours, the money he made each hour is equivalent to the rate of change. That means that in order to get the amount of money made in one hour, you must first turn the ten hours into one using division. Since you divided ten into one using division, you divide the $228.00 by ten using division.
228 divided by 10 is 22.8, therefore Cooper is making $22.80 per hour.
Step-by-step explanation:
Slope is the ratio of the vertical and horizontal changes between two points on a surface or a line.
If coordinates of any two points of a line are given then the rate of change is the ratio of the change in the y-coordinates to the change in the x-coordinates.
