Colin’s piano lesson is 45 minutes, or Three-fourths of an hour, long. If he practices 6 different songs and spends an equal amount of time on each song, what fraction of an hour does he spend practicing each song?

Colin spends 1/8 of an hour practicing each song

Step-by-step explanation:

Colin's piano lesson is 3/4 of an hour, long.

In that period, he practices 6 different songs, spending an equal amount of time on each one.

This means that each song gets the sixth part of the lesson duration. The fraction that expresses that amount is:

Colin spends 1/8 of an hour practicing each song

180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
