Ayouth ice hockey game has 3 periods that are each 20 minutes long. colin plays 12 minutes each period. which ratio shows colin's playing time compared to the total number of minutes playing time possible

3 periods, 20 minutes each

20 * 3 = 60 minutes

12 minutes per period

12 * 3 = 36

So the ratio is 36:60, or simplified: 3:5

Ice Hockey Game (Possible): 3 periods each 20 minutes long so 3 times 20 = 60
Colin's Play time: 3 periods each 12 minutes long so 3 times 12 = 36

Ratio - 36:60, 36 to 60, 36/60 or if simplified 3:5, 3 to 5, 3/5

36:60 or 3:5

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
