1. Find the total number of class members
9 + 11 = 20
2. Find 9 as a percentage of 20
9 / 20 = 0.45
0.45 x 100 = 45%
<u>45% of the class are girls.</u>

YOur greeatest common factor is 216. If you prime factor them it comes out to 216. Good luck.
Answer:
= 78
= 3.5
Step-by-step explanation:
First we need to find .
We can use the equation to solve for .
We can then change that equation to , since the Commutative Property of Addition says that you can have any addition in any order.
Now, we can solve the equation.
Now that we solved , we can now solve for .
Since 25 equals , we can solve the equation .
Here is how you solve it:
Since equals 3.5, which is the simplest form, that is the answer.
Hope this helps, and please mark me brainliest! :)
<span>So we want to know how much ball bearings can be made with 5.24 cm^3 if one ball bearing has a diameter of 1 cm. We know that radius r=d/2=0.5cm So the volume V of one ball bearing is: V=(4/3)*pi*r^3 so V=(4/3)*3.14*(0.5)^3cm^3=0.524cm^3. Now we simply divide the volume of steel by the volume of the ball bearing: 5.24/0.524=10. So we can make 10 ball bearings from 5.24 cm^3 of steel</span>
