Answer:
A total of 15 matches were played.
Step-by-step explanation:
To determine the number of matches that were played in the chess tournament, knowing that there are 16 participants who face each other in a tournament of direct elimination, the following logical reasoning must be carried out:
In the first round there are 16 players, so being matches between 2 players, there are 8 matches (16/2). In the second round, applying the same reasoning and taking into account that there are only 8 players left, since the others have been eliminated, there are 4 matches (8/2). The same in the semifinals, where there are 2 games (4/2), and finally, the final to a single game.
Therefore, since 8 + 4 + 2 + 1 equals 15, the number of matches played in the tournament is 15.
Answer:
Im not sure, is this correct?
I think answer is -1/6............
All 4 sides of a square are of the same length.
The formula for the area of a square is s*s = area where s is the length of one side of the square.
s^2 = 81
s = 9 or -9
-9 does not apply here but 9 does.
Each side of the square deck is 9 feet long.
