Answer:
first choice
Step-by-step explanation:
The volume of a rectangular prism is L*H*B.
So the volume of the rectangular prism pictured here is 24*10*8
The volume of a triangle prism is 1/2 *H*L*B.
So the volume of the triangle prism pictured here is 1/2 *6*24*8
The volume of the whole figure is the sum of the volume of the rectangular prism and volume of the triangular prism which is in this case:
24*10*8 + 1/2 *6*24*8.
Answer is the first choice.
(It wouldn't be third because 10 has nothing to with the triangular prism part)
N=28
cross multiply 7 and 36
cross multiply 9 and n
7x36=252
9xN=9n
9n=252

6 pennies, 12 nickels, 8 dimes, 4 quarters = 30 coins
a) add the probability for drawing a dime and drawing a quarter together:
12/30 + 4/30 = 16/30 = 8/15
The probability is 8/15 or 53%
b) multiply the probability for drawing a penny and drawing a nickel:
6/30 x 12/30 = 72/900 = 2/25
The probability is 2/25 or 8%
c) multiply the probability for drawing quarters but take away one of the total coins and the amount of quarters each time:
4/30 x 3/29 x 2/28 = 24/24360 = 1/1015
The probability is 1/1015 or 0.099%
Area = the top semicircle + the rectangle AEBD
= 1/2 pi*6^2 + 6*12 = 128.55 cm^2 to nearest 100th
Perimeter = 6pi + 12 + 2 pi * 3 = 49.70 cm
