Use the equation 6.25h = 100 to find h use the nuberof hours she will have to work to earn the money
Taya2010 [7]
If you just want to solve for h, as it appears, isolate h by dividing both sides of the equation by 6.25. 

That leaves h = 16.  (16 hours, presumptively).

Find the rectangular coordinates of (7, 150°)
Y_Kistochka [10]

Answer:

The coordinates are (-7sqrt(3)/2, 7/2).

Step-by-step explanation:

The rectangular coordinates from polar coordinates is found by:

x = r*cos(theta)

y = r*sin(theta)

Substituting the given values, we get:

x = 7*cos(150 deg) = 7*(-sqrt(3)/2) = -7sqrt(3)/2

y = 7*sin(150 deg) = 7*(1/2) = 7/2

The coordinates are (-7sqrt(3)/2, 7/2).

I hope this helps! :)
