First, like in the first solution, split the large hexagon into 6 equilateral triangles. Each equilateral triangle can be split into three rows of smaller equilateral triangles. The first row will have one triangle, the second three, the third five. Once you have drawn these lines, it's just a matter of counting triangles.AMC 10 2016 B. Question 1.

All information (Rules and Instructions) needed to administer this exam is contained in the TEACHERS’ MANUAL. PLEASE READ THE MANUAL BEFORE FEBRUARY 17, 2016. 2. Solution 3 (exponent pattern) Since we only need the tens digits, we only need to care about the multiplication of tens and ones. (If you want to use mathematical terms then we only need to look at the exponents in .) We will use the " " sign to denote congruence in modulus, basically taking the last two digits and ignoring everything else.Solution 3 (Fast And Clean) The median of the sequence is either an integer or a half integer. Let , then . 1) because the integers in the sequence are all positive, and ; 2) If is odd then is an integer, is even; if is even then is a half integer, is odd. Therefore, and have opposite parity. Solution 3. We know the sum of each face is If we look at an edge of the cube whose numbers sum to , it must be possible to achieve the sum in two distinct ways, looking at the two faces which contain the edge. If and were on the same edge, it is possible to achieve the desired sum only with the numbers and since the values must be distinct.Solution 3 (exponent pattern) Since we only need the tens digits, we only need to care about the multiplication of tens and ones. (If you want to use mathematical terms then we only need to look at the exponents in .) We will use the " " sign to denote congruence in modulus, basically taking the last two digits and ignoring everything else.We can use 4 yards as the unit for the dimensions. And let the dimensions be a * b, then we have one side will have a+1 posts (including corners) and the other b+1 (see example diagram below with a=4 and b=3). The total number of posts is 2 (a+b)=20. Solve the system b+1=2 (a+1) and 2 (a+b)=20, We get: a=3 and b=7.2020 AMC 10A problems and solutions. This test was held on January 30, 2020. 2020 AMC 10A Problems. 2020 AMC 10A Answer Key.
