Answer:
The rate of change of water in the pool is 400 gallons / hour
Step-by-step explanation:
We are given
At 6:00 AM:
there were 400 gallons of water in the pool
so,
At 11:00 AM:
there were 2400 gallons of water in the pool
so,
now, we can find time between
t=11-6=5 hours
now, we can use formula
rate of change of water in pool is
=( change in water quantity)/( total time)
so, we get
now, we can plug values
So,
The rate of change of water in the pool is 400 gallons / hour
Welcome to Brainly! :)
I cannot understand your equation, therefore I have put it as 36x + 8y + 2. If I'm wrong let me know and I'll fix everything. :)
We need to plug in our values for what we are given.
Let us learn about plugging in.
Let's start with an example equation:
1x + 3y + 1 - Values: y = 2, x = 4 This is a simple equation.
- When it tells you to plug in or tell you the values, that's your ket to plug in the variable for what it tells you.
Now, let's solve this example, our equation is:
1(4) + 3(2) + 1
Now, we have the original equation but plugged in. Next we simplify:
4 + 6 + 1
Add it up and get 11.
Great! Now that we are done with notes, we can solve.
36x – 8y + 2
It tells us that x = 3 an y = 6. Like the equation, we need to plug it in.
Great, now we need to simplify.
Cool, now we simplify and get 128!
Great job!
I hope you had amazing experience with brainly! :D
