Answer to Question #2788 in Abstract Algebra for d4522
Matt can clean his house in 6 hours and his sister can do it in 9 how long will it take the two together?
Let's denote the work to be done as X, thus productivity of Matt is X/6 , of sister X/9. If they work together, theirs productivity should be added.& Therefore, the time is& (work to be done)/(productivity) = X/(X/6 + X/9) = 1/(1/6 + 1/9) = 1/ (5/18) = 18/5 = 3,6 hours.
I’ve used Assignment Expert twice now, and I’m a full fledged fan. This morning I had a crunching 7 hour deadline for a huge programming assignment I forgot was due, and turned to them for help. The estimate was affordable and easy to pay for through PayPal. Shortly after, an expert got to work on the problem at hand. The operator was in constant contact with me throughout the entire process, and everything went quickly and smoothly. After looking through the assignment, I was happy to find that everything ran very smoothly, and no shortcuts were taken/no requirements were omitted. I wish I could say more about this service. It’s truly a game changer and has saved my back more than once now.
