First lets get the formula for a triangular prism

First lets plug in our numbers

It really doesnt matter how you multiply everything, but you end up with 119cubic feet.
Tan(35)=x/12
x=12*tan(35)=8.40
A mean is an average of a total. If you add all the pets together and divide by the number of people, you get the mean. So 1 +3 + 2 + 4 + 0 = 10
You have 10 pets in total.
There are 5 people.
Mean = 10 pets / 5 people = 2 pets per person. that's the mean or average that everyone has.
Answer:
a = 4/3
Step-by-step explanation:
1/3 a
----- = -----
5 20
Using cross products
1/3 * 20 = 5a
20/3 = 5a
Divide each side by 5
20/3 * 1/5 = 5a/5
4/3 = a
The second answer is the correct answer
