Answer:
   (√7)/3
Step-by-step explanation:
The relationship between tangent and cosine is ...
   tan(α) = √(1/cos(α)² -1)
The cosine of the angle is given as 3/4, so the tangent is ...
   tan(arccos(3/4)) = √(1/(3/4)² -1) = √(16/9 -1) = √(7/9)
   tan(arccos(3/4)) = (√7)/3
 
        
             
        
        
        
Answer:
3 feet
Step-by-step explanation:
the volume of the aquarium is V= Lx wx H  
it is as of now given that V=11.25 cubic feet, so 11.25=LxWxH  
H tallness and it is the aquarium's profundity  
H=11.25/L xW= 11.25/2.5x1.5= 3 feet
 
        
                    
             
        
        
        
Divide the number of events by the number of possible outcomes
        
                    
             
        
        
        
The answer is 460 because you have to subtract
