Answer:
20%
Since Emily gave 15 of her buttons out of 75, it's just 15/75 or 1/5 which is 20
Step-by-step explanation:
3sinx+1=sinx
2sinx+1=0
2sinx=-1
sinx=-1/2
x=sin^-1 (1/2) = 30 =

/6 (when finding the inverse, always take the positive value, ignore the negative sign)
x is therefore negative in 3rd and 4th quadrant
Therefore values of x are:
180+30=210 = 7

/6
360-3=330 = 11

/6

Answer:
C
Step-by-step explanation:
By the definition of negative indices, we can rewrite our expression:

And by the definition of fraction powers, we can rewrite our term:
![\frac{1}{y^-^\frac{4}{3} }=\frac{1}{(\sqrt[3]{y})^4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7By%5E-%5E%5Cfrac%7B4%7D%7B3%7D%20%7D%3D%5Cfrac%7B1%7D%7B%28%5Csqrt%5B3%5D%7By%7D%29%5E4%7D)
Not sure if that's what C says because the picture is kinda blurry.
