You are a race event coordinator. You are putting up a sign 70% of the way through a 10-mile race to let runners know how much farther they have to go to reach the finish line. How much of the race, in kilometers, will the runners
have left to complete at this point? Round to the nearest tenth if necessary

answer: .75 km

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

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

83-45=38

38 was the other number

hope your goes well, here's a turkey
