Answer:
8)61.5 9)42.1
Step-by-step explanation:
8)61.5
area of square 10×10=100
circle=pie r^2
3.5^2×pie
=38.5
100-38.5=61.5
9)14×14=196
14/2=7
7=radius
pie×7^2
=153.9/2(because circle is half)
=76.95
76.95×2
=153.9
=196-153.9
42.1

Multiply, because the total price is ten percent more than the original: $75 x 1.1 = <span>$82.5</span>
Total fees = 1.95% of 336,500 + $100 + 0.3% of 10% of 336,500 = (0.0195 x 336,500) + $100 + (0.003 x 0.1 x 336,500) = 6,561.75 + 100 + 100.95 = $6,762.70
Let the number of hour it took them to have completed the same number of problems be x, then
15 + 10x = 9 + 12x
12x - 10x = 15 - 9
2x = 6
x = 6/2 = 3
After 3 hours, they must have completed the same number of homeworks.
