Answer:
36 %
Step-by-step explanation:
x% = x/100
27/75 = x/100
100 · 27/75 = 100 · x/100
2700/75 = x
36 = x
36%
9 divided by 3 is perfectly 3
Answer:
area = 81π in² (or ≈ 254.47 in²)
Step-by-step explanation:
The formula for an area of a circle is area = πr².
You are given the diameter, which is 18 in.
diameter = radius (2)
So to get radius, divide the diameter in half:
18/2 = 9.
Now that we have the radius, put that back into the formula for the area of a circle:
area= π9²
Then, solve for the 9², which will be 81 and put it back into the formula.
area = 81π in²
If you need to get rid of the π, the answer will be about 254.47 in²
I say the answer is d let me know if im wrong
To solve a system of inequalities we graph both of them.
The inequality representing their combined pay would be

. This is because Jane makes 12.50/hr, Jack makes 10.00/hr, and they want to make at least, so greater than or equal to, $750 combined.
The inequality representing their combined hours working would be

, since they do not want their combined hours to be over 65. In both of these inequalities, <em>x</em> represents the number of hours Jane works and <em>y</em> represent the number of hours Jack works.
To graph these, we solve both of them for <em>y</em>:


The attached screenshot shows what the graph looks like. Going to the point where they intersect, we see that the shaded region that satisfies both inequalities begins when Jane works 40 hours and Jack works 25.
