Free movie, F = 87pts

Initial reward, I = 10pts

Additional reward, A = 7pts

Movie visit, X

F = I + XA

87 = 10 + 7X

X = (87-10)/7

X = 11

After 11 movie visits Andrew will have enough points for a free movie.

Calculate the pay for the following day of a

USPshnik [31]

Answer: $122.50

Step-by-step explanation:

In Out

8:00 12:00 = 4 hours

12:45 17:30 = 4.75 hours

Total 8.75 hours

8.75 hours x $14/hr = $122.50

Note: to subtract 12:45 from 17:30, borrow 1 hour from 17 and add 60 minutes to 30:

17:30 → 16:90

- 12:45 - 12:45

4: 45

4 hours 45 minutes = $4\frac{3}{4}$ = 4.75 hours

Find the rectangular coordinates of the point with the polar coordinates ordered pair negative 7 comma 5 pi divided by 3.

olchik [2.2K]

$\bf \begin{array}{clclll}
(-7&,&\frac{5\pi }{3})\\
\uparrow &&\uparrow \\
r&&\theta
\end{array}\qquad 
\begin{array}{clclll}
(x&,&y)\\
\downarrow &&\downarrow \\
r\cdot cos(\theta)&&r\cdot sin(\theta)
\end{array}$

so.. to get the x,y coordinates, or rectangular ones, get the cosine and sine of that angle, and multiply it times the "r"adius

You are hiking uphill, because it’s adding, not subtracting..
