The least of these numbers is the LCM. To minimize the LCM, we need the smallest primes, and we need to repeat them a lot. By inspection, we find that . Finally, . Problem 1.

The same argument applies to each of the fol-lowing half-minutes until all the toys are in the box for the first time. Therefore it takes 1 + 27 · 1 = 28 half-minutes, which is 14 minutes, to complete the task. 5. AoPS Community 2017 AMC 10 4 Mia is ”helping” her mom pick up 30 toys that are strewn on the floor. Mia’s mom manages to put 3 toys into the toy box every 30 seconds, but each time immediately after those 30 seconds have elapsed, Mia takes 2 toys out of the box.

We can solve this by using 'casework,' the cases being: Case 1: Amelia wins on her first turn. Case 2 Amelia wins on her second turn. and so on. The probability of her winning on her first turn is . The probability of all the other cases is determined by the probability that Amelia and Blaine all lose until Amelia's turn on which ...Solution 1. Because , , , and are lattice points, there are only a few coordinates that actually satisfy the equation. The coordinates are and We want to maximize and minimize They also have to be non perfect squares, because they are both irrational. The greatest value of happens when and are almost directly across from each other and are in ...2017 AMC 10A Problems 6 21. A square with side length x is inscribed in a right triangle with sides of length 3, 4, and 5 so that one vertex of the square coincides with the right-angle vertex of the triangle. A square with side length y is inscribed in another right triangle with sides of length 3, 4, and 5 Case 1: The red cube is excluded. This gives us the problem of arranging one red cube, three blue cubes, and four green cubes. The number of possible arrangements is . Note that we do not need to multiply by the number of red cubes because there is no way to distinguish between the first red cube and the second. Case 2: The blue cube is excluded.2017 AMC 10A Problems 6 21.

In total there are ways in which Laurene and Chloe can choose numbers (as same number cannot be chosen by both). If Chloe chooses 2017, then Lauren has 2017 ways to win, if Chloe chooses 2016, Lauren has 2018 ways to win and so on until if Chloe chooses 0, Lauren has 4034 ways to win.

Solution 1. must have four roots, three of which are roots of . Using the fact that every polynomial has a unique factorization into its roots, and since the leading coefficient of and are the same, we know that. where is the fourth root of . (Using instead of makes the following computations less messy.) Substituting and expanding, we find that.My experience taking AMC 10A and AMC 10B-2017. February 2017 meera. American Math Competitions are fun but not easy at all. It is always a humbling experience as there is no such thing as an easy AMC. Most (if not all) problems in the AMCs are something that you have not seen before and you have to solve 25 problems in 75 minutes.Solution 2. clearly has at least three distinct prime factors, namely 2, 5, and 11. The number of factors of is when the 's are distinct primes. This tells us that none of these factors can be 1. The number of factors is given as 110. The only way to write 110 as a product of at least three factors without s is .…
