In this experiment, the scientist cools the gases. This means that she decreases the temperature of the gases.
Based on this, the changes in the temperature will be negative for this experiment to indicate that the gases are losing energy (heat energy).
Answer:
60mph
Step-by-step explanation:
<u>Given:</u>
The width of the snack box is 
The length of the snack box is 
The height of the snack box is 4 inches.
We need to determine the volume of the hamsta snack box.
<u>Volume of the box:</u>
The volume of the box can be determined using the formula,

where L is the length, W is the width and H is the height of the box.
Substituting the values, we get;

Simplifying, we get,


Thus, the volume of the Hamsta snack box is 15 cubic inches.
<u>Answer:</u>
Michelle purchased 25 audio files in January. The percent increase is 60%
<u>Solution:
</u>
Given Data:
Michelle purchases = 25 audio files in January
Again purchased = 40 audio files in February
We need to find the percent increase for the given data.
Step 1:
Use the formula for percent change
,

Step 2:
First we find the amount of change from the question.
Amount of change = 40 – 25
By subtracting, we get 15.
Step 3:
substitute the values in formula we get,
Formula percent change =
= 0.6
Percent = 0.6
100 = 60 %.
Result:
Michelle purchased 25 audio files in January. And In February she purchased 40 audio files. Hence the percent increase is 60%.
