Answer: The volume of the tent is 293.33 ft.
Explanation: 11 x 10 x 8 = 880
The formula for the volume of a right rectangular pyramid is lwh/3. 
880/3 = approximately 293.33
 
        
             
        
        
        
Answer:
the lcm would be 30 not 60 
Step-by-step explanation:
 
        
                    
             
        
        
        
-1/12 - (-11/12) would change into -1/12 + 11/12 because a double negative (bold print) would become a positive. The answer to the new problem would be 10/12 or 5/6 (depending on if it says to simplify).
 
        
             
        
        
        
Replace f(x) with y
switch x and y
solve for y
replace y with f⁻¹(x)
f(x)=x-1
y=x-1
x=y-1
x+1=y
x+1=f⁻¹(x)
f⁻¹(x)=x+1
        
                    
             
        
        
        
∠1 and ∠2 are RIGHT ANGLES, VERTICAL ANGLES, and SUPPLEMENTARY ANGLES. 
Hope this helps!
