Answer:
75 minutes
Step-by-step explanation:
The rate at which the tank is filled up, F, and emptied, E, are respectively:
Since V is the full volume of the tank, the time required to fill the tank if both pipes are open is given by:
It will take 75 minutes to fill the tank if both pipes are open.
Answer:interest =p×r×t ÷100
Time = 21/2 -5/2
Interest = 7150×5×5/100×2
answer =1787.5
Amount = P-I
7150-17875/10
Answer = 5362.5
Step-by-step explanation:
The best possible solution for this item is to determine the permutation of 8 taken 3 since there are 3 positions and 8 people are qualified. We will use permutation instead of combination because of the specificity of the positions. That is,
