Answer:
answer is .A
Step-by-step explanation:
1) We know that volume= base area x height, so 306.52= 19.4 x height.
To find the height you have to divide 306.52/19.4 which would give you the height. The height is 15.8m.
Answer: two over three
Step-by-step explanation:

line intercepts y at (0,-2)
Therefore, 
Substitute x = 3 in y =ax-2

To find the x-intercept, y = 0

The slope is 2/3
y-intercept is -2
So two over three
