What is the actual distance between the cities?

Actual distance between two city = 40 miles

Step-by-step explanation:

Given sample size;

1 inch = 10 miles

Distance between two city = 4 inch

Find:

Actual distance between two city

Computation:

Actual distance between two city = Sample size of 1 inch in miles x Distance between two city

Actual distance between two city = 4 x 10

Actual distance between two city = 40 miles

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
