Single Elimination Practice - Forecasting Number of Days

See if you guys can give these a shot!

Under the conditions below, find the number of days it will take to conduct a single elimination tournament.  Assume no team is playing more than ONCE per day:

1.  N=39 teams
    Number of games that can be played each day: 7

2.  N=64 teams
    Number of games that can be played each day: 10

3.  N=44 teams
    Number of games that can be played each day: 5

4.  N=19 teams
    Number of games that can be played each day: 4

Here's a word problem:

You are the intramural coordinator for Momma's and Daddy's University.  Your director has asked you to determine the number of days it will take to play your intramural basketball playoffs, consisting of 38 teams.  You have the facility reserved Monday through Thursday and you are able to play 6 games per day.
