1/9 + 1/2 = 1/x
Let x = length of time it will take both hoses to work together
Multiply both sides by 18x.
2x + 9x = 18
10x = 18
x = 18/10
x = 9/5
x = 1.8 hours
In other words, if both hoses work together, the pool can be filled in 1 hour and 48 minutes.
Length of one edge is 10cm
And the surface area is 600cm2
Answer:
(0,4) is the y intercept for function A
(0,3) is the y intercept for function B
so function A has the greatest y intercept
Step-by-step explanation:
Answer:
(3,10)
Step-by-step explanation:
When x is 3

y is 11, and this is invalid because it is not at accord.
P+prt
1000+1000(.06)x=2500
X=25
