Answer:
4 hours
Step-by-step explanation:
First we need to subtract the one pay fee (the helmet rental fee, $15)
So 51 - 15 = 36
Then we need to divide 36 by the amount of money it costs for each hours to find how many hours he rented the bike
So 39/9 = 4
Answer:
<h3>
This means that about 21 level truck loads are necessary to remove all dirts.</h3>
Step-by-step explanation:
To get the number of level truck loads needed to remove all the dirts in the house, first we need to calculate volume of the truck and the house.
Volume of truck = Length * Breadth * Height
If the truck is 5.0 for the length 2.0 for the height 3.0 for the side base;
Volume of the truck = 5*2*3
Volume of truck = 30
For the house;
Volume of house = Length * Breadth * Height
If the house is 4.0 for the height 14.5 for the length and 11.0 for the side base, then
Volume of the house = 4*14.5*11 = 638
Number of level truck loads needed to remove all the dirts = Volume of house/Volume of the truck = 638/30 ≈ 21.3
This means that about 21 level truck loads are necessary to remove all dirts.
3/4 * 5/7 = 15/28 or 0.5357
