Answer:
20%
Step-by-step explanation:
To find the percent decrease, we do old number subtracted from the new numbers over old.
We do
40 - 32 = 8
Then we put the 8 over the old and get
8/40
In percentage form it would be 20%
Answer:
Step-by-step explanation:
If you draw a horizontal line through the shaded triangle such that it intersects the left vertex, you see that it bisects the 60° angle at that vertex. The measure of x is the same as the measure of either half of that bisected angle, so is 30°.
The pitch associated in the table with an angle of 30° is 7.
Using proportions, it is found that she runs 3.106855 miles in one week.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Researching this problem on the internet, it is found that the measurement is in meters, and we want to find the number of miles. She runs 5,000 meters. Each meter has 0.000621371 miles, hence the number of miles that she runs is given by:
M = 5000 x 0.000621371 = 3.106855 miles .
Maria runs 3.106855 miles in one week.

For the first month, the membership fee deducted = $15
So, -15(1) will represent this situation.
Similarly, for the second, third, fourth months, the expressions will be:
-15(2), -15(3), -15(4) and so on.
Hence, if t represents the number of months, then -15t will represent ash's art club membership being deducted every month for a year.
You have the area of a triangle by this formula;
A = 1/2 × base × height.
and you just plug in which numbers are the base and height to find the area of it.
hope this helps, God bless!
