70 POINTS PLEASE HELP! A dump truck pours sand into a container in the shape of a rectangular prism with a square base of length

galina1969 [7]

Answer:

Step-by-step explanation:

The volume of a rectangular prism is:

$V=\ell wh$

Since the prism has a square base, each side length being 2, this means that both the length and width of our prism is 2. Therefore:

$V=(2)(2)h=4h$

So, we can write:

$V=4h$

The height h increases at a rate of about 8 inches or 8/12 = 2/3 feet per minute.

So, after t minutes, the height will be 2/3(t) feet. Thus, we can substitute:

$\displaystyle V=4\Big(\frac{2}{3}\Big)t=\frac{8}{3}t$

We want to find after how long it will be until the volume is 64 cubic feet. So, V = 64:

$\displaystyle 64 = \frac{8}{3} t$

Solve for t:

$\displaystyle t=\frac{3}{8}(64)=3(8)=24\text{ minutes}$

The correct answer is A.

A ball is thrown into the air with a speed of 32 feet per second. The function h=32t - 16t^2 models the height of the ball after

beks73 [17]

Answer:

t = 1 s

Step-by-step explanation:

The function models the height of the ball after t seconds is given by :

$h=32t - 16t^2$

We need to find how many seconds does it take for the ball to reach its maximum height.

For maximum height put dh/dt = 0

$\dfrac{dh}{dt}=\dfrac{d}{dt}(32t - 16t^2)\\=32-32t$

So,

32-32t = 0

t = 1

So, it will take 1 second to reach its maximum height.

George has $15. He would like to know if he has enough money to see a movie ($9.00) and buy a pretzel ($2.65), a drink ($1.35),

notsponge [240]

Answer:

Yes, he has enough money and your simplified answer is below. If I'm wrong correct me or give me a comment.

Step-by-step explanation:

15 - 9 + 2.65 + 1.35 + 2(1.74) Multiply first.

15 - 9 + 2.65 + 1.35 + 3.48 Then just add or subtract from the left to the right

6 + 2.65 + 1.35 + 3.48

8.65 + 1.35 + 3.48

10 + 3.48

13.48 would be the simplified answer.
