Answer:
The data that we have is:
"Adrian's backyard pool contains 6.4 gallons of water. Adrian will begin filling his pool at a rate of 4.1 gallons per second."
Then we can write the amount of water in Adrian's pool as a linear function:
A(t) = 6.4gal + (4.1gal/s)*t
Where t is our variable and represents time in seconds.
We also know that:
"Dale's backyard pool contains 66.4 gallons of water. Dale will begin draining his pool at a rate of 0.9 gallons per second. "
We can also model this with a linear function:
D(t) = 66.4 gal + (0.9gal/s)*t
Both pools will have the same amount of water when:
D(t) = A(t)
So we can find the value of t:
6.4gal + (4.1gal/s)*t = 66.4 gal + (0.9gal/s)*t
(4.1gal/s)*t - (0.9gal/s)*t = 66.4gal - 6.4gal
(3.2gal/s)*t = 60gal
t = 60gal/(3.2gal/s) = 18.75s
In 18.75 seconds both pools will have the same amount of water.
Answer:
nth day: w:x:(y-2(n-1))
Step-by-step explanation:
Let Original time = w:x:y
Where w is the hours, and x is the minutes, and y is the seconds.
Sadie's time on the first date: w:x:(y-2)
Second day: w:x:(y-4)
Third day: w:x:(y-6)
and so on
nth day: w:x:(y-2(n-1))

Answer:
9
Step-by-step explanation:
If u add 12.50 and 6.50 together u get 19 and if u multiply 19 up to 175$, Then u only get to bring 9 people and if u multiply 19 x 9 u get 171 if u multiply it more u will go over the budget so 9 is the correct answer.
