Answer:
a) y = -500x + 130,000
b)67,500 gallons remaining
c) 260 hours
Step-by-step explanation:
Since water is being removed at a rate of 500 gallons per hour, the slope would be a negative.
a) y = -500x + 130,000
For<u> part b</u> input 125 for x:
y = -500(125) + 130,000
y = 67,500
There are 67,500 gallons remaining
For part c we are solving for the x intercept
0 = -500x + 130,000
Subtract 130,000 from both sides
-130,000 = -500x
x = 260
It will take 260 hours for the pool to completely drain
Answer:
19/30
Step-by-step explanation:
If the probability of an event happening is 11/30, then you simply subtract 11 from 30 to find the remaining "possibilities"
30 - 11 = 19
So- this means that the probability of the event NOT happening, is...
19/30
Hope this helps!
