The correct answer for this question is "<span>|x-6| > 4."
</span>All real numbers more than 4 units from 6 (in an absolute value inequality).
We need to translate this sentence into a mathematical inequality.
"... units from 6 ..."
This means that the distance from 6 to a certain number.
x - 6
Since, we are talking about distance, place it inside an absolute symbol.
Answer:
about 180
Step-by-step explanation:
Answer:
V = pi*x^2*(18x - 45)
Step-by-step explanation:
If the diameter is 6x and the height is 2x + 5, we know that the radius is 3x.
Plugging this info into the volume-of-a-cylinder formula V = pi*r^2*h, we get:
V = pi*(3x)^2*(2x - 5), or V = pi*(9x^2)(2x -5), or:
V = pi*(18x^3 - 45x^2), or V = pi*x^2*(18x - 45)
It takes 3 pumps 16 hours to empty a tank
Meaning it takes 48 hours for one pump by its self
So if there are 4 pumps
48/4 it would take them 12 hours
They would need to work 12 hours to do it in 1 day
20/5+8^2*2-9
20/5+64*2-9
4+64*2-9
4+ 128-9
132-9
123
I hope this helped!
