Answer:-

If there is to be only one winner, than there are 99 loses, therefore, there were 99 matches. You can also do this with math: in round 1 there would be 50 matches to produce 50 winners, round 2 would have 25 matches to produce 25 winners, round 3 would have 12 matches to produce 12 winners ( one person of the 25 winners would have to wait until later to play again ), round 4 would have 6 matches to produce 6 winners, round 5 would have 3 matches to produce 3 winners, round 6 would have 2 matches ( the player left out before would now play to make it an even field ) to produce 2 winners, these 2 would play for the championship. So: 50+25+12+6+3+2+1=99

Alternate Answer:
The first round is 50 matches eliminating 50 golfers, the second is 25 matches eliminating 25 golfers. For the third round the remaining 25 are divided into pools of 5 at random and face two matches each (each vs. a different randomly selected opponent in the pool). I think you will find that there will be two golfers and two only from each pool who will be dual winners. They will advance. The third round was then 5 pools of 5 matches so 25 more matches (100 total so far). The fourth round will be 5 matches eliminating 5 golfers. These five participate in a pool (fifth round) just like the third round (5 more matches and 2 emerge). The two play the championship match. So by round the matches are: 50+25+25+5+5+1 = 111 matches

Answers:
 

01. "48 mph".
Explanation:
Say the journey takes 120 miles.
The first half of the journey (60 miles) takes 60÷40 = 1.5 hours, the second half takes 60/60 = 1.0 hour. So, the journey of 120 miles takes 1.5 + 1.0 = 2.5 hours and therefore, the average speed is 120÷2.5 = 48 mph.

02. "17".
Explanation:
Add the number of items together, which gives 83 + 77 + 62 + 95 = 317 among 100 women.
This gives three items to each and four items to 17 of these women.
The least number of women to have all three items is, therefore, 17.

Answers:

01. First find the common denominator for the numbers 3, 4, 6, and 8. The only common denominator less than 30 is 24. Therefore, the students with a "B" = 8, "B-"= 6, "C" =4, failed = 3. This represents 21 of the students; so the 3 remaining students received an "A".

02. Divide 250 by 11 which equals 22.8. Now when you combine the extra 8 scraps with the scraps you'll have from the 22 bars, you'll have 30 more scraps. They will produce 2 more bars; so the total additional bars will be 24.

03. If Kerry eats 3 times as fast as Pete, he must be able to eat 3 times as many dumplings as his brother. Therefore, Kerry eats 24 while Pete eats 8 ( 32 ÷ 4 = 8 ). Together it takes them 45 minutes.

Answers:

01. Add the equation to give: 10000X + 10000Y = 50000
Divide by 10000 to give: X + Y = 5
Subtract to give: 3502X - 3502Y = 3502
Divide by 3502 to give: X - Y = 1
Therefore: X = 3 and Y = 2

7. If there is to be only one winner, than there are 99 loses, therefore there were 99 matches. You can also do this with math: in round 1 there would be 50 matches to produce 50 winners, round 2 would have 25 matches to produce 25 winners, round 3 would have 12 matches to produce 12 winners ( one person of the 25 winners would have to wait until later to play again ), round 4 would have 6 matches to produce 6 winners, round 5 would have 3 matches to produce 3 winners, round 6 would have 2 matches ( the player left out before would now play to make it an even field ) to produce 2 winners, these 2 would play for the championship. So: 50+25+12+6+3+2+1=99

7a. ALTERNATE ANSWER
The first round is 50 matches eliminating 50 golfers, the second is 25 matches eliminating 25 golfers. For the third round the remaining 25 are divided into pools of 5 at random and face two matches each (each vs. a different randomly selected opponent in the pool). I think you will find that there will be two golfers and two only from each pool who will be dual winners. They will advance. The third round was then 5 pools of 5 matches so 25 more matches (100 total so far). The fourth round will be 5 matches eliminating 5 golfers. These five participate in a pool (fifth round) just like the third round (5 more matches and 2 emerge). The two play the championship match. So by round the matches are: 50+25+25+5+5+1 = 111 matches

8. If the trains are moving toward each other we combine their speeds to give us their speed basis. So: 55+80=135mph. Divide this speed by 60 minutes to give the speed they are traveling each minute=2.25 miles/minute. Therefore: 2 minutes before impact they are 4.5 miles apart.

9. 24 mph. Most people are quick to answer 25 mph, but this is not correct, as we will see. Let the distance traveled be 60 miles each way. Then, the trip out = 60/30 = 2 hours, and the trip back = 60/20 = 3 hours.
Therefore: the 120 mile trip = 120/5 = 24 mph.

10. The answer is 297 seconds, not 300 as most people would suppose. This is because the 100 pieces are made in 99 cuts. The last cut made results in 2 pieces instead of only one piece.
