Since he gets paid more for tutoring, he should work as many hrs tutoring as possible. He can only work at most 20 hrs. He has to work at least 3 hrs tutoring but no more then 8 hrs.....to maximize profit, he needs to work 8 hrs tutoring...leaving 12 hrs as a teachers aide. He should work 20 hrs to maximize his earnings.
maximum profit is : 8(10) + 12(7) = 80 + 84 = 164
<span>D = 180 * (n -2)
D = 180n -360
180n = D +360
n = (D / 180) + 2
So, the answer is "A"
And we can test this with a square, sum of angles = 360
n = (D / 180) +2
n = (360 / 180) +2
number of sides = 4
correct

2:4/5
= 2/(4/5)
= 2*(5/4)
= 5/2
= 5:2
3/4:3/10
= (3/4)/(3/10)
= (3/4)*(10/3)
= 5/2
= 5:2
Because 5:2= 5:2, 2:4/5 and 3/4:3/10 form a proportion~
