Answer:
y = -10
Step-by-step explanation:
(-7x+3y) - (-7x +10y) =-65 -(-135)
-7x + 3y + 7x -10y = 70
-7y = 70
y = -10
 
        
                    
             
        
        
        
Answer:
0.37 feet. 
Step-by-step explanation:
The following data were obtained from the question:
Volume (V) = 4100 ft³
Height (h) = 1.8 miles 
Radius (r) =? 
Next, we shall convert 1.8 miles to foot. 
This can be obtained as follow:
Recall:
1 mile = 5280 ft 
Therefore, 
1.8 miles = 1.8 × 5280 = 9504 ft
Finally, we determine the radius as follow:
Volume (V) = 4100 ft³
Height (h) = 9504 ft
Pi (π) = 3.14
Radius (r) =? 
V = πr²h
4100 = 3.14 × r² × 9504
4100 = r² × 29842.56
Divide both side by 29842.56
r² = 4100/29842.56
Take the square root of both side 
r = √(4100/29842.56) 
r = 0.37 ft 
Therefore, the radius of the hole is 0.37 feet.
