Answer:
It will take 13.5 minutes for the liquid to reach - 10.8°C.
Step-by-step explanation:
The initial temperature of the experiment is 0°C and as the experiment goes on, the temperature of the liquid is changing at a rate of - 0.8°C per minute.
So, the equation that models the situation is
T = 0 - 0.8t
⇒ T = - 0.8t ................. (1)
Where T is the temperature of the liquid in °C and t is the time of spending after the experiment starts in minutes.
Now, given T = - 10.8°C and we have to find the corresponding time (t) in minutes.
So, from equation (1) we get,
- 10.8 = - 0.8t
⇒ t = 13.5 minutes
Therefore, it will take 13.5 minutes for the liquid to reach - 10.8°C. (Answer)
Answer:
h = 4 cm
Step-by-step explanation:
The formula for volume of a cylinder is
V = πr²h where V is the volume, r is the radius, and h is the height.
We are given V = 64π, and r = 4, plug those in and solve for h
64π = π(4²)h
64π = 16πh
(64π)/(16π) = (16πh)/(16π) (divide both sides by 16π)
4 = (16π)/(16π)h
4 = h
If you have an equation like 4 + w = 12, you'll work backward to find w by subtracting 4 from 12.
Or if you have an equation like 4r = 24, you'll work backward by dividing 24 by 4 to find r.
