Find the midpoint of BD.

(a/2, a/2)

Step-by-step explanation:

Coordinates of B & D are; (0, a) and (a, 0) respectively.

The formula for calculating coordinates of midpoint is;

M = ((x1 + x2)/2), ((y1 + y2)/2)

Coordinates of BD will be;

M_BD = ((0 + a)/2), ((a + 0)/2)

M_BD = (a/2, a/2)

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
