It's really embarrassing that I can't help my nephew with his 4th grade homework. I am not cheating, I am finished with Hs and college but I don't remember the 4th grade. That was back in the 80s. My nephew goes to a special school with Kids who have learning and behavior problems. It's called the Kennedy center located here in Michigan.
Just a few more questions and I wont bother you again.
1. A gear with 31 teeth is engaged with another gear that has 22 teeth. How many turns of the first gear are necessary in order for the two gears to return to their original position?
Part B. A with 32 teeth engaged with 50 teeth
2. Mellisa has some 5 dollar bills, Sean has some 10 dollars bills and Lugi has some 50 dollars, If they attend to buy the same item with there money, what is the least price they could pay without receiving change? ( I told him to put No answer because it's no specific, am I right)
