Answer:
22 + 3pi
Step-by-step explanation:
The width of the rectangle is 6. The height of the rectangle is 8. The diameter of the semicircle is 6.
perimeter = 8 + 6 + 8 + (1/2)(pi)d
perimeter = 22 + (1/2)(pi)(6)
perimeter = 22 + 3pi
7(12 1/3) + 8(12 1/3 + 1/4) = 3(6(12 1/3) - 9) - 8
12 1/3 = 12.33
1/4 = 0.25
7(12.33) + 8(12.33 + 0.25) = 3(6(12.33) - 9) - 8
86.31 + 8(12.58) = 3(73.98 - 9) - 8
86.31 + 100.64 = 3(64.98) - 8
186.95 = 186.94 - 8
186.95 ≠ 178.94
False. The x, when 12 1/3 does not work inside this equation

Answer:
green balloons = (3/5) * 40 = 24
yellow balloons = 24 / (2/3) = 36
40 + 24 + 36 = 100
she bought 100 balloons.
Answer:
the perimeter is 48 and the apothem is 72
Step-by-step explanation:
its all just a bunch of multiplication. You multiply 6 (because there is six sides to your perimeter) by 8 and then you have 48. for the apothem. the apothem is a sliver of you perimeter
