Answer:
"The rate of Hose A is 1 gallon per minute more than the rate of Hose B"
Step-by-step explanation:
Hose A:
60 gallons every 15 minutes means
60/15 = 4 gallons per minute
Hose B:
y = 3x
y is gallons
x is minutes
we put x = 1 and get:
y = 3*1 = 3
That means 3 gallons per minute
Thus,
the correct choice is C), or third option. 4 is 1 greater than 3 so Hose A is 1 gallons per minute more than the rate of Hose B.
Answer:
choice f
Step-by-step explanation:
take ∆ abc
ab^2 = ac^2 + ab^2
400 = 225 + ab^2
ab =√ 175
∆aDB
bd = 20-x
ad^2 = 175 -(20-x)^2
∆acd
225 = x^2 + 175 - 400+ 40x - x^2
225 = -225 + 40x
450 = 40x
x = 45/4
