Creating an online course is monumental, especially for a small website like MATHalino. Despite being managed by only one person from the ground up, the development of this functionality has been progressing gradually. I have been conceiving this feature for as long as I can remember, even before online courses became common in the Philippines.
What prevented me from implementing it earlier came down to three factors.
Three or more are defective.
Find the capacity of the tank in liters.
Find the rate of pipe C in liters per minute
A tank is supplied by two pipes A and B and emptied by a third pipe C. If the tank is empty and all pipes are opened, the tank can be filled in 20 hours. If the tank is full and A and C are opened, the tank can be emptied in 4 hours. If the tank is full and B and C are opened, the tank can be emptied in 2 hours. Pipe A supplies 50 liters per minute more than B.
The volume at 420°K
Charles’s law states that for a given mass of gas at constant pressure the volume is directly proportional to its thermodynamic temperature. A gas occupies a volume of 2.25 liters at 400°K. Determine the following:
