In order to measure the height of a tree (without having to climb it) Andy measures the length of the tree's shadow, the length of his shadow, and uses his own height. If
Andy's height is 5.6 ft, his shadow is 4.2 ft long and the tree's shadow is 42.3 ft long,
how tall is the tree? Create a proportion and show your work.

Iwill make brain if you me correctly fill this out needs due today pls and send it back to me (click the link and you will get it)

Nine more than four times a number is the same as one less than twice the number. find the number?

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?
