Answer:
Step-by-step explanation:
If 3⁄4 gallons of water come out of a hose in 15 minutes, to calculate the rate of water that comes out in an hour (60 minutes), we will use the expression;
3/4 gallons = 15 minutes
x gallons = 60minutes
cross multiply
15x = 3/4 * 60
15x = 180/4
15x = 45
x = 45/15
x = 3/1
x = 3:1
Hence the water rate in gallons per hour is 3 gallons per hour
Answer:
P(King) = 4/52 = 1/13
Step-by-step explanation:
As we know there are 52 cards in total from 2 to 10, and King, Queen, Jack, and Ace, with each of them are equal in numbers which is 4.
Total Number of Kings in the Deck of Cards = 4
P(King) = Number of Kings/Total Number of Cards
= 4/52 = 1/13
This is the commutative property
