Stephen drove from Manchester to Liverpool. He drove at an average speed of 60 miles per hour, for half an hour. How far did he drive?
miles

30 miles

Step-by-step explanation:

1h = 60 min

60mph/ 60 min = 1mph per minute

1h/2 = 30 min (only half an hour)

30 x 1(mph) = 30

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
