Answer:
we first need to turn every thing into the same unit of measure ment
1 gallon=4 quarts 60 minutes=1hour
7*60=420 420 is how many quarts per hour but we want gallons so we want to divide by 4 420/4=105 105 gallons per hour
Answer 2
Answer:
so qt=quart 4 quart=1 gallon 1 quart=1/4 gallon min=minute 60 minutes in 1 hour 1 minute=1/60 hour
so 7 quarts=7 times 1/4 gallons=7/4 gallons 1 minute=1 times 1/60 hours=1/60 minutes
7/4 gallons per 1/60 minutes (7/4gal)/(1/60h) we don't really need to divide so multiply the whole thing by (1/60)/(1/60) to clear bottom fraction (7/4 times 60/1)/(1/60 times 60/1)=(420/4)/(60/60)=(420/4)/(1) =420/4=210/2=105/1=105 gallons per hour
Mr. Smith has two children. If the older child is a boy, what are the odds that the other child is also a boy?
Answers
50% Because 2 people are there and if 1 is a boy there's a 50% chance that there's another boy. For example you had 2 gumballs in a gumball machine. You picked one up. There would be chances of picking up 1 of the other. So there's a 50% chance of picking a gumball. :D hope this helps.
