Solution 3. Again note that you want to maximize the number of s to get the maximum sum. Note that , so you have room to add a thousands digit base . Fix the in place and try different thousands digits, to get as the number with the maximum sum of digits. The answer is . Solution Problem 4 All lines with equation such that form an arithmetic progression pass through a common point. What are the coordinates of that point? Solution Problem 5 …

Solution 2. Alternatively, we could have used similar triangles. We start similarly to Solution 1. Drawing it out, we see and are right angles, as they are inscribed in a semicircle.

Solution 1. In the diagram above, notice that triangle and triangle are congruent and equilateral with side length . We can see the radius of the larger circle is two times the altitude of plus (the distance from point to the edge of the circle). Using triangles, we know the altitude is . Therefore, the radius of the larger circle is .

Solution 1. Let's first work out the slope-intercept form of all three lines: and implies so , while implies so . Also, implies . Thus the lines are and . Now we find the intersection points between each of the lines with , which are and . Using the distance formula and then the Pythagorean Theorem, we see that we have an isosceles triangle ...

Solution 1. Without loss of generality, let and . Let and . As and are isosceles, and . Then , so is a triangle with . Then , and is a triangle. In isosceles triangles and , drop altitudes from and onto ; denote the feet of these altitudes by and respectively. Then by AAA similarity, so we get that , and . Similarly we get , and .Solution 1. Without loss of generality, let and . Let and . As and are isosceles, and . Then , so is a triangle with . Then , and is a triangle. In isosceles triangles and , drop altitudes from and onto ; denote the feet of these altitudes by and respectively. Then by AAA similarity, so we get that , and . Similarly we get , and .Solution 4. Let have a distance of from the home. Then, the distance to the gym is . This means point and point are away from one another. It also means that Point is located at So, the distance between the home and point is also. It follows that point must be at a distance of from point . However, we also said that this distance has length .Solution 3. Again note that you want to maximize the number of s to get the maximum sum. Note that , so you have room to add a thousands digit base . Fix the in place and try different thousands digits, to get as the number with the maximum sum of digits. The answer is .Solution 1. The number of tiles the bug visits is equal to plus the number of times it crosses a horizontal or vertical line. As it must cross horizontal lines and vertical lines, it must be that the bug visits a total of squares. Note: The general formula for this is , because it is the number of vertical/horizontal lines crossed minus the ...Solution 3. The perpendicular bisector of a line segment is the locus of all points that are equidistant from the endpoints. The question then boils down to finding the shapes where the perpendicular bisectors of the sides all intersect at a point. This is true for a square, rectangle, and isosceles trapezoid, so the answer is .These mock contests are similar in difficulty to the real contests, and include randomly selected problems from the real contests.
