1/8
Step-by-step explanation:
 
        
                    
             
        
        
        
4 minutes 34 seconds will takes to empty the tank, if the starts completely full and oil drained at a rate of 2.5  per minute.
 per minute.
Step-by-step explanation:
               The given is,
                          Tank is shaped like a cylinder that is 3 ft long with a diameter of 2.2 ft.
                           Oil drained at a rate of 2.5  per minute.
 per minute.
Step:1
        Time taken to dry the oil tank is,
                            T   =  ....................................(1)
  ....................................(1)
Step:2
        Volume of the oil is,
                             .................................................(2)
.................................................(2)
       Where, r - Radius of Cylinder
                               
 
                              
                               r = 1.1 ft
       From eqn (1),
                         V =   ×
 ×  × 3
 × 3
                            = 11.40398 
Step:3
       From equation (1)
                            =  
 
                            = 4.56
                            = 4.56 minutes
                       T  = 4 minutes 34 seconds
Result:
        Time taken to dry the oil tank is 4 minutes 34 seconds, if a cylinder is 3 ft long with a diameter of 2.2 ft and oil is drained at a rate of 2.5ft^3 per minute.
 
        
             
        
        
        
We have the following table:
Round Number of Strokes Above or Below 72
 1 -5
 2 +6
 3 -2
 4 -4 
 5 +5
So, the expression that represents the total number of strokes is:
72 + (Number of strokes Above or below 72)
Therefore, for every round we get:
Round Number of Strokes Above or Below 72 Total number of strokes
 1 -5 72 - 5 = 67
 2 +6 72 + 6 = 78 
 3 -2 72 - 2 = 70 
 4 -4 72 - 4 = 68 
 5 +5 72 + 5 = 77 
The total number of strokes is: 
67 + 78 + 70 + 68 + 77 = 360
Additionally, the average is the total number of strokes divided by the number of rounds, so it is equal to:

Answer: Total: 360 Strokes
 Average: 72 Strokes
 
        
             
        
        
        
Answer: -27
Step-by-step explanation: the cube has a volume of -27 because -3 to the 3rd power (cubed) is -27
