A = c^2/(4π) = (24.5 in)^2/(4π) ≈ 47.766 in^2
Answer:
There are 90 ways.
Step-by-step explanation:
We have ten people and we have to chose 2 of those people to be the president and vice president. So first we can chose a president, we have 10 choices for president as there are 10 people.
Now we can chose vice president but this time we only have 9 choices because we already chose a president which gives us 9 other people to chose who the vice president is.
Now we need to multiply 10 and 9 together which gives us the total amount of possible combinations for president and vice president if there are 10 people to chose from.
10*9 multiplying
= 90.
Therefore there are 90 ways for a president and a vice president to be chosen for a sorority from ten people.
So the way to figure out the sides of a right triangle, is basically
A^2 + B^2 = C^2
Letter A is the only one that would work, because the first number squared (times itself), added to the second number squared, would equal the third number squared. This is a basic principle of the pythagorean theorem, which I can explain in more detail if you'd like. :)
