Answer:
 
Volume of Cylinder A is                          pi times the area of the base times the height 
                                                              π r2 h = (3.1416)(4)(4)(15) = 753.98 ft3 
 
Volume of Cylinder B is likewise             pi times the area of the base times the height 
                                                              π r2 h = (3.1416)(6)(6)(7)   = 791.68 ft3 
 
After pumping all of Cyl A into Cyl B
there will remain empty space in B         791.68 – 753.98 = 37.7 ft3  
 
The percentage this empty space is
of the entire volume is                            37.7 / 791.68 = 0.0476 which is 4.8% when rounded to the nearest tenth

The answer would be (4,3)
        
             
        
        
        
I think the answer is (x-2 ) x ( x+2)
        
                    
             
        
        
        
<span>The equation that can be used is 90-10y=5x. In order to get this answer, you first start with figuring out how many miles total were hiked for each trail. The 5-mile mountain trail total would be equal to 5x and the 10-mile canal trail total would be 10y. Adding both of these totals together would give you 90 miles and an equation of 5x+10y=90. All you do now is rearrange the equation by subtracting 10y from each side and you get 90-10y=5x.</span>
