Answer:
40.56
Step-by-step explanation:
you need the circumference of the cirle aka perimeter of circle so 8(pi) and then because its only half, divided by 2... 12.56
now you hgave circumference so add 12.56 to 28 and there you go. you can round how ever necessary
<em><u>Complete Question:</u></em>
The equation a= 180(n-2)/n represents the angle measures, a, in a regular n-sided polygon. When the equation is solved for n, n is equal to a fraction with a denominator of a – 180. What is the numerator of the fraction?
<em><u>Answer:</u></em>
The numerator of fraction is -360
<em><u>Solution:</u></em>
Given that,
<em><u>The equation represents the angle measures, a, in a regular n-sided polygon is:</u></em>
![a = \frac{180(n - 2)}{n}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B180%28n%20-%202%29%7D%7Bn%7D)
We have to solve the equation for "n"
Rearrange the equation
![a \times n = 180(n - 2)\\\\a \times n = 180n - 360\\\\an - 180 n = -360\\\\Take\ n\ as\ common\ factor\\\\n(a-180) = -360\\\\n = \frac{-360}{a - 180}](https://tex.z-dn.net/?f=a%20%5Ctimes%20n%20%3D%20180%28n%20-%202%29%5C%5C%5C%5Ca%20%5Ctimes%20n%20%3D%20180n%20-%20360%5C%5C%5C%5Can%20-%20180%20n%20%3D%20-360%5C%5C%5C%5CTake%5C%20n%5C%20as%5C%20common%5C%20factor%5C%5C%5C%5Cn%28a-180%29%20%3D%20-360%5C%5C%5C%5Cn%20%3D%20%5Cfrac%7B-360%7D%7Ba%20-%20180%7D)
Thus the numerator of the fraction is -360

Answer:
5/6
Step-by-step explanation:
If q is the quantity of cereal in the box before Heba ate some, the problem tells us ...
q - 1/12 = 3/4
q = 3/4 + 1/12 = 9/12 + 1/12 = 10/12
q = 5/6
There was 5/6 of a box before Heba ate.
