In the first 2 hours after meadow's self-service laundry opens, m large washing machines and n small washing machines are in continual use. including the time for filling and emptying the washing machines, each load of laundry takes 30 minutes in a large washing machine and 20 minutes in a small washing machine. what is the total number of loads of laundry done at meadow's self-service laundry during this 2-hour period?

Nt=10 (m=4,n=6)

Step-by-step explanation:

we have that m = amount of time used by the large washing machine to wash a load of clothes and n = amount of time used by the small washing machine to wash a load of clothes, so

Nt=m+n=10

where Tt = time frame, Tpm= m' time frame, Tpn = n' time frame and Nt = total number of charges

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
