Answer:
6 feet 
Step-by-step explanation:
Volume of a rectangular prism = L × W × H 
15 feet × 8 feet × H = 720 feet ³ 
120H = 720
H = 720 ÷ 120
H = 6 feet
 
        
             
        
        
        
45/4 * 4/3 = 45/3 is the answer
        
                    
             
        
        
        
In order to add these fractions we have to make a common denominator.
1/5 can turn into 2/10 Its the same thing. And its easier to solve with. 
now lets multiply. 
 ×
 × 
Now we add across 
2 + 1 = 3 
------------  
10 + 10 = 10 ( When adding fractions like these the denominator stays the same)
So your answer is...

Good Luck! :)
 
        
             
        
        
        
Answer:
x = 80°
Step-by-step explanation:
The full angle of the straight line is 180°. We already have 100°, so we need to find out what is left over for x
180 - 100 = 80
So the angle of x is 80°
