Suppose that 17 inches of wire cost $0.85 at the same rate how many inches of wire can be bought for $0.55

11 inches

Step-by-step explanation:

17/0.85 * 0.55

20 * 0.55

11.

answer

106 emergencies

step-by-step explanation:

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
