Definitely B. Note how the powers of y are presented in descending order by power: y^8, y^7, y^1.
For number 5:
1 ) 60
2) 600
3) 6 x 10 x 10 x 10 = 6000
4) 6 x 10 x 10 x 10 x 10 = 60000
5) 6 *10^4
Answer:
As shown in picture,
volume of cone V = base area x height x (1/3) = pi x (4/2)^2 x 6 x (1/3) = 8 x pi
volume of cup V = base area x height = pi x (3/2)^2 x 3 = 6.75 x pi
(all the volumes are in cubic inches)
A - Incorrect
24 pack of cups: V = 24 x 6.75 x pi = 162 x pi
21 pack of cones: V = 21 x 8 x pi = 168 x pi
162 x pi < 168 x pi
B - Correct
12 pack of cups: V = 12 x 6.75 x pi = 254.5 > 250
C - Correct
14 pack of cones: V = 14 x 8 x pi =351.9 > 350
D - Correct
Volume of cylinder 8 tall, 6 wide: V = pi x (6/2)^2 x 8 = 72 x pi
12 pack of cups: V = 12 x 6.75 x pi = 80.4 x pi > 72 x pi
Hope this helps!
