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.
Answer:
30 inches
Step-by-step explanation:
She takes 12 equal sized steps and they all add up to 10 yards.
The length of each step (in yards) is:
10 / 12 = 5/6 yards
The question requires the answer in inches, therefore, we must convert this to inches:
1 yard = 36 inches
5/6 yards = 5/6 * 36 = 30 inches
Each step is 30 inches long.
To convert a mixed fraction into an improper fraction:

For the surface area u take the surface and multiply the length by the width which is in this cas 7x4 then multiply, 7x4 is equal to 28.
Hope this helped, tell me if I’m wrong
