2 months.
the equations are
65m+50 and 45m+90
you set them equal together
65m+50=45m+90 
and you get 2.

Answer:
31.42ft 
Step-by-step explanation:
diameter = 10
radius = diameter ÷ 2
r = 10 ÷ 2
r= 5
Circumference = 2(pie)(r)
 = 2(22÷7)(5)
 = 31.42ft
 
        
                    
             
        
        
        
There are 4 lateral faces that are triangles.  Each triangle is: A = 

A = 

   = 176
There is one base that is a square. A = L x W
A = 16 x 16
   =  256
Surface area = 256 + 4(176)
                     =  256 + 704
                     = 960

Answer:
3200 ft-lb
Step-by-step explanation:
To answer this question, we need to find the force applied by the rope on the bucket at time 
At 
After  seconds, the weight of the bucket is
 seconds, the weight of the bucket is 
Since the acceleration of the bucket is the force on the bucket by the rope is equal to the weight of the bucket.
If the upward direction is positive, the displacement after  seconds is
 seconds is 
Since the well is 80 ft deep, the time to pull out the bucket is 
We are now ready to calculate the work done by the rope on the bucket.
Since the displacement and the force are in the same direction, we can write
