Answer:
0.6 °C/min
Step-by-step explanation:
The relationship between rates and movement is ...
time = distance/speed
Here, the "distance" is measured in °C, and the "speed" is the rate of change of temperature.
For the first half of the heating, the time required is ...
(50°C -0°C)/(1.5 °C/min) = 50/(3/2) min = 100/3 min
For the second half of the heating, the time required is ...
(100°C -50°C)/(4/10 °C/min) = 50/(4/10) = 125 min
Then the total time is ...
((100/3) +125) min = (475/3) min
And the average rate of temperature increase is ...
total temperature change / total time
= (100°C -0°C)/(475/3 min) = 300/475 °C/min = 12/19 °C/min ≈ 0.6 °C/min
Answer:
The 3rd set
Step-by-step explanation:
The first set has a range of 6, not 5
The second set has a range of 5, but not a mean of 5
The third set has both a mean and a range of 5
X is 57
That means y is 36.
Sorry, I’m gonna try not explain it because I’m rlly bad at explaining and all I’m going to do is confuse you even more...
<h2>1210 cubic feet</h2>
Step-by-step explanation:
Initial dimensions of the storeroom were 
length, 
width and 
height.
The room is in the shape of a cuboid. Volume of a cuboid = 
, where 
are the length, width and height of the cuboid.
So, Volume of storeroom initially = 
Finally, the length was increased to 
and width to 
.
Final volume of storeroom = 
Increase in volume = 
∴ 1210 cubic feet of storage was added.
