Answer:
Two pieces of furniture.
Step-by-step explanation:
3 hours times 1 piece of furniture every 3/4 hours:
3 · =
=
= 2.25
Assuming that pieces of furniture cannot be sold in parts, 2 whole pieces of furniture will be sold in 3 hours.
What is the exact volume of the composite solid below? Do NOT round at any point!
1 answer:
So, let's take a look! When doing volume, we always do (addition) and nothing else. The only time that we would have to multiply is if we would have to find the area, but in this case, we are (going to figure) out what would be the volume.
We would sum up the following:
.
I believe that we would multiply this by (2) because we would have to find the other side as well.
And this would give us . . . 64 as it's volume.
V= (64)

Answer:
51.877 kg
Step-by-step explanation:
a
See attachment for calculations
b
The amount of salt in the tank after 4 hours is gotten by simply replacing t in the equation from a, with 4 hours. Since the t gotten in a above is in minutes, we'd convert hours to minute as well. If we do that, we have
t = 4 hours = 4 * 60 minutes = 240 minutes
y = 160/3 (1 - e^((-3 * 240)/200))
y = 160/3 (1 - e^(-720/200))
y = 160/3 (1 - 0.0273)
y = 160/3 (0.9727)
y = 51.877 kg
Therefore, the amount of salt in the tank after 4 hours is 51.877 kg
