Since the decimal of 8% is 0.08 te fraction is 8/100 and in simpest form it is 2/25 The closest benchmark is 2/25
35/100 = 0.35
0.35 x 125 = 43.75
43.75 litres per day
Answer:
678.24 cubic feet.
Step-by-step explanation:
A pile of gravel is in the shape of a cone.
Radius of base of cone (r) = 9 feet
Height of the cone (h) = 8 feet
Volume of the cone (V) = ?
We know that, volume of a conical shape of radius 'r' and height 'h' is given as:

Now, plug in the given values and use 3.14 for π. Solve for 'V'. This gives,

Therefore, the volume of the gravel of pile is 678.24 cubic feet.
the real world situation for ratio 29 to 30 is that their are 29 boys to 30n girls meaning less number of boys to girls in the class
