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:
7= 2 4/5 8=2/21 9= 6 3/7 10= 1/6 11= 7/5 12=77/90
Step-by-step explanation:
3 1/5= 16/5-2/5=14/5 which equals to the same thing to 2 4/5
5/3= 35/21
11/7= 33/21
35/21-33/21= 2/21
3 3/4=15/4 times 12/7 straight ahead which is 180/28 equals to the same thing as 45/7 = 6 3/7
1/5 times 7/1 so u flip it over as u can see which is 7/5
2 1/5= 11/5 2 4/7= 18/7 11/5 times 7/18=77/90

Answer:

Step-by-step explanation:
Question 2 Fill in the blanks to complete the sentence.
A recipe for sparkling grape juice calls for 1 1/2 quarts of sparkling water and 3/4 quart of grape juice.
a. How much sparkling water would you need to mix with 9 quarts of grape juice?
3/4 quarts of grape = 1 1/2 quarts sparkling water
9 quarts of grape = x
x = (9 × 1 1/2) ÷ 3/4
x = (9 × 3/2) × 4/3
x = 27/2 × 4/3
x = 18 quarts of sparking water
b. How much grape juice would you need to mix with 15/4 quarts of sparkling water?
1 1/2 quarts of sparkling water = 3/4 quarts of grape
1 5/4 quarts of sparkling water = x
x = (3/4 × 15/4 ) ÷ 1 1/2
x = (0.75 × 3.75 ) ÷ 1.5
x = 1.875 quarts of grape
c. How much of each ingredient would you need to make 100 quarts of punch?
Round your answer to the nearest whole quart. sparkling water: quarts grape juice: quarts

The number 19/7 ( a rational or an irrational )

plz answer
Answer:
rational
Step-by-step explanation:
Answer:
Rational number
Step-by-step explanation:
The definition of a rational number is "A number such as -3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q." The definition of an irrational number is "All the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers." This means 19/7, and all improper fractions, are rational numbers.
Select all the relations that represent a function.

1. (1, 3), (2, 5), (2, 7) (4,9) The 2 is used more than once as a x-coordinate. Not a function.

A baker regularly uses flour to make pastries for the bakery at the beginning of the month of the Baker has a 25 pound bag of flour. Each week she uses 5 3/5 pounds of flour write an expression to represent the change in weight of the bag of flour over four weeks
Answer:
At the beginning, she has 25lb of flour.
Each week, she ses (5 + 3/5) pounds of flour.
Then after the first week, she has a total of:
W(1) = 25lb - (5 + 3/5)lb
After another week, she has:
W(2) = 25lb - (5 + 3/5)lb - (5 + 3/5)lb = 25lb - 2*(5 + 3/5)lb
and so on.
if x represents the number of weeks, the equation is:
W(x) = 25lb - x*(5 + 3/5)lb
where x can be {0, 1, 2, 3, 4}
That is the equation that represents the change in the weight for the first four weeks.
