Answer:

a). Volume of Tank=35 liters

b). Number of marbles=375 marbles

Step-by-step explanation:

a).Volume of the Tank

For the tank to be full Andrei needs;

  • 50 marbles each with a volume of 0.04 liters

Total volume of marbles=50×0.04=2 liters

  • 33 liters of water

Total volume of water= 33 liters of water

The total volume of the tank=Total volume of marbles+Total volume of water=(33+2)=35 liters

b). How many marbles he needs when the tank is full.

Volume of Tank when full=Total volume of marbles+Total  volume of water.....equation 1

Total volume of water is known=20 liters

Total volume when tank is full=35 liters and

Total volume of marbles=Number of marbles×volume per marble

Where Number of marbles is unknown=N, and volume per marbles=0.04 liters

Total volume of marbles=(N×0.04)

Substituting in equation below;

Volume of Tank when full=(Total volume of marbles)+(Total  volume of water).....equation 1

35=(N×0.04)+(20)

(35-20)=(N×0.04)

Solving for N

(N×0.04)/0.04=15/0.04

N=375

N=Number of marbles=375 marbles

Pretty Sure it is 3 laps. because if it is 4 laps = 1 mile. then 1/4 = 1 lap 2/4= 2 laps 3/4 = 3 laps and then 4/4 = 4 laps = 1 mile.


Hope this helps :)
