If we put that into an equation, we get
(5/9)(f/32)
because "five ninths" is a fraction, "times" is multiplication (which can be represented by parenthesis), "the difference" is division, and "the difference of f and 32" is a fraction.
Answer:
9/16
Step-by-step explanation:
Next time write the mixed number like this:
1 1/3 just so you know so ppl can answer it better
So firstly, foil (x-8)(x-2): 
Next, remember that the vertex lies on the axis of symmetry, and the equation to find the axis of symmetry is
(a = x^2 coefficient, b = x coefficient). Solve for the axis of symmetry as such:

So now that we know that the axis of symmetry is x = 5, we also know that's the vertex's x-coordinate (since the vertex falls on the axis of symmetry). Now plug in 5 for x in the original equation to solve for f(5):

So putting it together, the vertex of this equation is (5,-9).
Answer: 48 divided by 6
Step-by-step explanation:
48 divided by 6 = 8

Answer: 1 hour</h3>
==================================
Explanation:
In the method I show below, the value 600,000 liters is never used. All that matters are the two values of 100 minutes and 150 minutes.
Pipe A drains the pool in 100 minutes. The rate it drains the pool is 1/100 of a pool per minute. If you multiply 1/100 by 100, then you'll represent 1 full job being done (that job being draining the pool).
Pipe B drains the pool in 150 minutes. Pipe B's rate is 1/150 of a job per minute.
In total, the combined rate is
1/100 + 1/150 = 3/300 + 2/300 = 5/300 = 1/60 of a pool per minute
This means it takes them 60 minutes to drain the pool assuming the two pipes work the most efficiently together (ie one pipe doesn't hinder the other). Since 60 minutes = 1 hour, it's much easier to say it takes 1 hour to drain the pool with both pipes working together.
---------------------------------
We can get this same answer through solving the equation
1/x + 1/y = 1/z
for z. Use x = 100 and y = 150.
