If there is any number of teams in a tournament, what is the minimum number of matches to know the positions of all teams?

For example:

4 teams (ABCD)

A vs B = A wins
C vs D = C wins
A vs C = A wins

A is number 1
B is number 2

B vs D = B wins

B is number 3
D is number 4

(4 matches)

What if there are 1024 teams in the tournament? How did you calculate it?

more advanced on, for whatever reason in a given area, or even equally survivable, can a Species devolve to resemble a previous evolutionary stage? I guess in my mind I am thinking about whales and dolphins coming to resemble fish again. So my question is, how is it known that all hominids are becoming less apelike and more man like, and some are not examples of taking a step to more apelike features because for whatever reason, those features make him more survivable? (A heavy skull and brow ridge, for example)

--P4 + HNO3 + H2O -> H3PO4 + NO
--KMnO4 + H2SO3 -> K2SO4 + MnSO4 + H2SO4 + H2O
--Zn + HNO3 -> Zn(NO3)2 + NH4NO3 + H2O
--Cu + HNO3 -> Cu(NO3)2 + H2O + NO
--FeSO4 + K2Cr2O7 + H2SO4 -> Fe2(SO4)3 + Cr2(SO4)3 + K2SO4 + H2O

Joan and Gayle sold 89 magazines. If Joan sold one more than three times the number Gayle sold, find the number sold by Joan.

I got 67, but I am not sure if that is correct.

If you could put it in "equation" form, that would be nice also.
