x = r cos \theta \\  \\ y = r sin \theta

x = (-2) cos (\pi/3) = (-2)(\frac{1}{2}) =-1 \\  \\ y=(-2) sin (\pi/3) = (-2)(\frac{\sqrt{3}}{2})=-\sqrt{3}

The rectangular coordinates are:
(-1,-\sqrt{3})

What does 15× 1/8 equal?
stealth61 [152]
Hey there!

15 = 15/1

1/8 = 1/8

15 x 1 = 15

1 x 8 = 8

= 15/8

Simplifying 15/8 . . .

15/8 = 1 7/8

15 x 1/8 = 1 7/8 <--------

1 7/8 is your answer.

I hope this helps you.

Have a great day! :)
