Answer:
- -2.2(6) +1.8(4) . . . temperature change
- 42 °C
Step-by-step explanation:
At the end of the first 6 hours, the temperature change was ...
(-2.2 K/h)(6 h) = -13.2 K
The change in the next 4 hours was ...
(1.8 K/h)(4 h) = 7.2 K
Then the total change over the 10-hour period was ...
(-2.2)(6) +(1.8)(4) . . . . . expression for temperature change
This evaluates to -13.2 +7.2 = -6.
__
The final temperature is the sum of the initial temperature and the temperature change:
final temperature = 48 °C -6 °C = 42 °C
_____
<em>Additional comment</em>
When temperature is measured on the Celsius scale, a change of 1 degree is called a kelvin (K).
Answer:
1/4
Step-by-step explanation:
15/60 = 1/4
Answer:
44
Step-by-step explanation:
1/2(n + 6) < 25 Distribute
1/2n + 3 < 25
- 3 - 3 Subtract 3 from both sides
1/2n < 22 Multiply both sides by 2 or divide by 1/2
n < 44

Answer: 13 cm^3
Step-by-step explanation:
The volume of a rectangular prism is the height*width*length.
3 1/4 as a decimal is 3.25.
Now we can plug in the given values into the formula for the volume.
Therefore, the volume = 3.25 cm * 4 cm * 1 cm
= 13 cm^3
