Step-by-step explanation:
Answer:
17 m
Step-by-step explanation:
As shown in the figure, 
is the ground level, 
is the old level of water which was at 20 m below ground level, 
is the new level of water which is 5m above of old level. The height of wall of the well, 1.20 m, and the the pelly at 80 cm =0.80 m, has been shown too.
The minimum length of the rope is equal to the distance between the pully and the new water level, indicated by the length 
in the figure.
So, 
Hence, Raghu must use a rope having the minimum length 17 m to draw water from the well.
<span>The cost of each mile is $2.50.
If you simplify the expression given you will get the following.
y = 3.75 + 2.50(x - 3)
y = 3.75 + 2.50x - 7.50
y = 2.50x - 3.75.
Knowing that x is the number of miles and 2.50 is the number being multiplied by, we know that the cost per mile is 2.50. </span>
The root of 77 is 8.774 so the answer is C
