Three motorcyclists ride around a circular course starting at the same place and the same time. The first passes the starting point every ​min, the second every ​min, and the third every min. After how many minutes will all three pass the starting point again at the same​ time? Explain your reasoning.

What is the upper quartile in the box plot?

What is the slope of the line that contains the points (-5, 6) and (14. - 7)?

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
