Answer:
5/10
Step-by-step explanation:
5+5=10. so 5 empty 0/10 5 shaded 5/10
OM and OP will coincide a second time after 120 seconds. You could visualize it as ray OP moving at 3 degrees/second relative to OM.
Using this visualization, we find that OM makes 30*60*3/360 rotations (minutes * 60 * rotational speed/360 degrees in a rotation), which is 15, and that OP makes 30*60*6/360 or 30 rotations, which is 15 more than OM.
A, c, and d
plug in each x in the equation and it should equal the y value
