So, We Have A Rate That We Need To Simplify. We Have:
88 students for every 4 classes
So, We Need To Simplify This Rate. In Order To Do This, We Need To Change Is To A Fraction. It Is:
88 students
---------------
  4 classes
Now, We Have To Simplify. We Can Do That By Remembering How To Simplify Fractions.
So, 
88 ÷ 2 =  44   ÷ 2  =   22 students
---            ---               ---------------
 4  ÷ 2 =   2    ÷ 2  =           1
So, The Unit Rate For 88 Students For 4 Classes Is:
22 Students For One Class
        
             
        
        
        
Answer:
See below 
Explanation:
You multiply 8 and 6.9 
To get 55.2 ounces
        
             
        
        
        
We know how we got 90, since a right angle is 90 degrees,
180 degrees are in a triangle.
180-90=90
Find the pair that equals 90 so you get 180 degrees!
If you have more questions don’t have hesitation to ask!
Or add all number to get 180 degrees!
 
        
             
        
        
        
Let P = Pressure, V = Volume and be K = constant, by definition of Boyle's Law in which says that the volume of a gas varies inversely with the pressure, we have:  P = K / V  586 = K / 5  K = 2930.  Then, the pressure when the volume is 2L will be:  P = 2930/2 = 1465Kpa
