In polar coordinates, the axis determined by theta=0 is called the
positive x-axis or horizontal axis.
To add, in mathematics, the polar coordinate<span> system is
a two-dimensional </span>coordinate<span> <span>system in
which each point on a plane is determined by a distance from a reference point
and an angle from a reference direction.</span></span>
Answer:
x = 6
Step-by-step explanation:
First, we need to cross multiply on both sides, which gives us:
9 * (5x - 6) = 27 * (2 + x)
45x - 54 = 54 + 27x
Now, we want to isolate x on either side.
We can substract 54 from both sides:
(45x - 54 = 54 + 27x) - 54
45x - 108 = 27x
We then subtract 45 from both sides:
(45x - 108 = 27x) - 45
-108 = -18x
Finally, we divide both sides by -18:
(-108 = -18x) / -18
6 = x
You multiply 8 by 15 then again by 6 so the answer is 720
Answer:
180
Step-by-step explanation:
The difference between 68 and 23 is 45. The company charging 23$ has to be 45$ more for the amount of hours. When you multiply 180 by .4 you get 72, and when you multiply 180 by .65 you get 117. The difference is 45.
Sorry that I didn't show my work, I don't really know how to do this other than plugging in random numbers and 180 fits so...
Hope this helps!
