Question 89424: The formula N=t^2-t/2
describes the number of football games, N that must be played in a league with t teams if each team is to play every other team once.
How do I use the above to solve this problem below
If a league has 36 games scheduled, how many teams belong to the league,assuming that each team plays every other team once? The book says 9 how would I set it up in the formula above. Answer by checkley75(3666) (Show Source):
You can put this solution on YOUR website! 36=T^2-T/2
T^2-T/2-36=0
USING THE QUADRATIC EQUATION WE GET (T=6.26 & -5.76)
SOLVING THIS EQUATION USING 9 AS THE NUMBER OF TEAMS (t) WE GET
N=9^2-9/2
N=81-4.5
N=76.5 THIS SAYS SOMETHING IS WRONG WITH YOUR EQUATION OR THE ANSWER 9 IS INCORRECT.
