Divide both sides by -0.7 to get rid of that pesky thing in the front
0.3x-0.8=6.4
add 0.8 to both sides
0.3x=7.2
divide both sides by 0.3
x=24

when does it hit the ground? check the picture below.

at that moment, the velocity is -32(3).
The volume of a spherical shaped object is given by

Given that the <span>solid ball has a radius of 20.0 millimeters, the volume of the solid ball is given by

Therefore, the </span><span>closest to the volume of the synthetic compound ball, in cubic millimeters is 33,500 cubic milimeters.</span>
Answer:
Hope this helps ________z
Ab/ac = ae/ad = be/cd
4/ac = 6/15
6 ac = 60
ac = 60/6 = 10
ac = 10
