 04-27-2010 #1 shadow123blast     Join Date: Feb 2010 Posts: 117 This is about MathCounts If you are reading good but I am going to start a Mock MathCounts post a comment if you want to join This should train you to win the school MathCounts competition and the Chapter at least the First problem i am taking from old sprint problems from chapter and state Problem 1 of the ste sprint of this year ( the winner of the NC MathCounts is Kavi Jain an 8th grader from our school he got a perfect score)Sharon bought a mixture of nuts that was made up of pecans, walnuts and cashews in a ratio by weight of 2:3:1, respectively. If she bought 9 pounds of nuts, how many pounds of walnuts were in the mixture? Express your answer as a decimal to the nearest tenth. There are 2 tests that affect your individual score The Sprint a quick 40 minute test for 30 questions that is why it is called the Sprint it is quick The Target a test of 4 different sheets that have 6 minutes for 2 questions total 8 questions 2 questions per sheet This is why it is called the target you have time to target the answer These are the most important if you are a individual competitor. The Team important for team but not individuals. 10 hard questions and you solve them in 30 minutes.(our school is very prestigious and got 5th in the states and 1st in the chapter competition.) sprint questions are 1 point each and target are 2 points each totaling to a 46 and perfect scores are ridiculously hard to get especially at the states (this is also in my blog please read 5 points for the first 5 people who answer correctly and post the comment on my blog)

This is the interesting part of MathCounts From now on i am going to give 3 points to the 1st person that answers the questions 1 questions each day on my blog from sate sprints then i will move to target team then countdown Sprint is 3 points for the 1st person 2 points for targets 5 points for team questions 2 for countdown problems For todays question actually 2 points for the first 5 people
 04-27-2010 #3 orac343     Join Date: Mar 2010 Posts: 11 oO believe me i really want to be good at Mathcounts i was really close to winning i need some practice i think your question was from the sprint of this year and the answer is 4.5 since 2+3+1 (this is the ratio)=6 you have 9pounds over 6 parts each part is 9/6 or 3/2 so 3/2 multiplied by 3 since respectively it is the 3 so you have 4.5 pounds
 04-28-2010 #4 shadow123blast     Join Date: Feb 2010 Posts: 117 answer that is a correct answer but you must post on the blog as i said to recieve your points so you must do so ok?
