Volume of the prism is given by:
V=(base area)*(height)
thus:
base area=1/2(a+b)*h
=1/2(1.4+0.6)*2
=2 m²

Thus the volume will be:
V=2*1
V=2 m³

Volume after 30 min:
V=2×(0.8)
V=1.6 m³

Rate of emptying the tank is:
(2-1.6)/30=1/ 75 m³/min
time taken to empty the tank:
time=volume/rate
time=2/(1/75)
=150 min

Ben drinks water everyday. He drinks 3 1/2 liters of water every 1/4 of an hour. Ben drinks water at a constant rate. How many l

Setler79 [48]

Ben drinks 3 1/2 liters of tea every 40 minutes.

This means that he would drink 1 3/4 of tea every 20 minutes (divide both sides by 2).

Now, let's multiply each side by 3.

1.75 * 3 = 5.25 (aka 5 1/4)

20 * 3 = 60 minutes (an hour)

He drinks 5 1/4 liters of tea in one hour.

If she wants to track to have a circumference of 150 feet , what does the radius of the track need to be?

Gemiola [76]

Solution:

we are given that

she wants to track to have a circumference of 150 feet.

we have been asked to find

what does the radius of the track need to be?

As we know that

$Circumference=2\pi r$

Substitute the values we get

$150=2 \pi r\\
\\
r=\frac{75}{\pi} \\
\\
r=\frac{75}{22/7}\\
\\
r=\frac{75*7}{22}= 23.863feet$

Hence radius=23.863 feet.
