a running track in the shape of an oval is shown. the ends of the track form semicircles.
a running track is shown. the left and right edges of the track are identical curves. the top and bottom edges of the track are straight lines. the track has width 46 m and length of one straight edge 150 m.
what is the perimeter of the inside of the track?
(π = 3.14)
392.00 m
372.22 m
444.44 m
588.88 m

444.44 is the answer                                                                                            

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
