Mark's model train can go 1/3 laps around its track in 2 minutes. If it runs at the same speed, how many laps can the train go in 9 minutes?

1.5 laps

Step-by-step explanation:

You can use a proportion to solve this problem.

2 minutes is to 1/3 lap and 9 minutes is to x laps.

2/(1/3) = 9/x

Cross multiply:

2x = 9 * 1/3

2x = 3

x = 1.5

1.5 laps

it has the same slope and a different y-intercept

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
