Segment AB falls on line 6x + 3y = 9. Segment CD falls on line 4x + 2y = 8. What is true about segments AB and CD? They are parallel because they have the same slope of −2.
They are perpendicular because they have slopes that are opposite reciprocals of −2 and one half.
They are parallel because they have the same slope of 2.
They are perpendicular because they have opposite reciprocal slopes 2 and negative one half.

Arecipe uses 2 cups of sugar to make 32 brownies. how many cups of sugar are needed to make 72 brownies?

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
