How many minutes are there in three quarters of an hour? explain your answer

60 mins in a hour
1/4 hour =60/4 which is 15 mins
1/2 hour=30
3/4 hour =45 mins

There are 45 minutes in 3/4 of an hour. i got this by dividing 60 minutes by 4 (60/4) then adding 15 three times (15+15+15) from this you get 45 minutes.

This question doesn’t make any sense

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.
