b has parallelograms and obtuse angles
<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%.
1. 4.625
2. 0.708
3. 8.75
4. -3.16

In Q.2 is it 22/3-11/8 or 2/3-11/8?
In Q.4 is it 41/3-21/6 or 1/3-21/6?
The first one can be proven by graphing the parallelogram and the diagonals.
The measure of angle 2 is 160 because it is a vertical angle to angle 1. The measure of angle 3 is 10 because the two other angles must each be 10 in order for the sum of all three angles to equal 180 for the triangles.
I have no idea for the third one however.
Hope this helps!
