<span>h=-16t^2+24t+1
6=-16t^2+24t+1
0 = -16t^2+24t-5
0 = 16t^2-24t+5
solve the above using the "quadratic formula" which yields:
t = {0.25, 1.25}

Only the triangular prism will hold 30 gallons of water.
First, we need to find the volume of the prism.
It is: V = (24 x 25)/2 x 28 = 8400 in^3
Since there are 231 cubic inches in a gallon, so there are 36.4 gallons in the tank. 8400 / 231 = 36.4
The pyramid would only have one-third of the volume.
The correct answer is C.
14%p can be written as 0.14p, since 14%=14/100=0.14.
Adding this to p means paying 100% of p plus an additional 14%. This would be equivalent to paying sales tax on a purchase.
