We can break √10 into √2 • √5, and √8 into √2 • √4, or, simplifying √4 to 2, 2 • √2. Our expression now becomes
(√2 • √5) / (4 • 2 • √2)
Cancelling the √2 in the numerator and denominator gets us
√5/(4 • 2), or √5/8.
Answer:
4 gallons
Step-by-step explanation:
The total required quarts of paint is: 8 x 1/2 = 4
73 (because you want more than 72 to break the record) - 10 = 63
63/9 ( the amount of minutes left) = 7
Joey would have to eat at least 7 hot dogs each minute to break his record.
x+10 > 72
hope this helps
