Express the shaded part of the picture as a fraction.

4/9

Step-by-step explanation:

there is nine boxes and that would be your denominator and the four shaded boxes would be your numerator

C. 4/9

Step-by-step explanation:

there are 4 shaded so the shaded parts represent the numerator is how many boxes there are in total is the denominator.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
