Alright, lets get started.
3 feet = 1 yard
If we cube both sides of the equation, we will get the conversion into cubic yards
So,

27 cubic feet = 1 cubic yards
So, 1 cubic feet =  cubic yards
 cubic yards
So, 360 cubic feet =  cubic yards
 cubic yards
So, 360 cubic feet = 13.33 cubic yards
13.33 cubic yards of air can it circulate per minute. : Answer
Hope it will help :)
 
        
                    
             
        
        
        
Answer:
1. 9/16 * 12/13 = 27/52
2. 7/10 * 5/28 = 1/8
Step-by-step explanation:
1. 
9 / 16 * 12/13 
9 * 12 = 108
16 * 13 = 208
108 / 208
Simplify: 
27/52
2. 
7 / 10 * 5 / 28
7 * 5 = 35
10 * 28 = 280
Simplify: 
1/8
 
        
                    
             
        
        
        
Let's assume 
shorter side as x
so, first side =2x
third side =x+19
now, we can find perimeter of triangle
perimeter of any triangle is 
first side + shortest side + third side
so, we get 

we are given perimeter=187
so, we can set it to 187
and then solve for x





so, 
shortest length is x=42 feet
First side =2x=2*42=84feet
third side =x+19=42+19=61 feet
so, dimensions are 
first side is 42 feet
second side is 84 feet
third side is 61 feet................Answer
