Riley says this picture represents 0.26 because the blue squares represent tenths and the red rectangles represent hundredths. 10 blue squares make 1 red rectangle, and 10 times 10 equals 100.

Use the drop-down menus to explain why Riley's reasoning is incorrect.

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

there are infinitely many solutions.
