1. an athletic facility is building an indoor track. the track is composed of a rectangle and two semicircles as shown
c=2
tv
a. write a formula for the perimeter of the track.
c=25tv + 2x
b. solve for x
c. if the perimeter of the track is 600 ft and the radius is 50 ft, find x to the nearest foot.

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.

To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1
