When you want to minimze something, you have to maximize the other possibilities. Teams A,B,C. If you want to minimze the number of points of A, you have to maximize the number of points of B and C. If B,C cannot have more than 6 points, so let's give them the maximum that we can:6 each. Given there...

That's a nice question. If x and y are positive integers, what is the remainder when 3^(4+4x)+9^y is divided by 10? (1) x=25 3^104 + 9^y= 9^52 + 9^y 9^52 is an integer with a unit digit which is 1. If y=1, it will give a multiple of 10 but if y=2, it will not give a multiple of 10. We have example/c...

It seems complicated to find P-T with each statement alone. Before chosing E you should try to find P-T, You see that in each average you Q,R,S so it's possible, let's try: With the two statements you have (P+Q+R+S)/4=388 250 --> (Q+R+S)/4=388 250 - P/4 (Q+R+S+T)/4= 383 000--> (Q+R+S)/4=383 000 - T/...

They tell you that
lal + lbl > la+bl
With a=2 and b=3 the inequality is wrong.
With a=-2 and b=-3 the inequality is wrong.
The only possibility is that a and b have opposite signs so as to put down la+bl

1) The measure of angle T is 100 The triangle is isocele so two angles have the same value. T is 100, and given you have 180° in a triangle, the other two angles have the same values:40 each Sufficient. 2) The measure of angle S is 40 Angle S is 40. We could have S=40 T=40 and R=100 or S=40 T=100 or...

This one is faster.
Let's say diameter of S is x.
The sides of the square are x.
The diagonal of the square is x*sqrt(2).
And the diameter of T is x*sqrt(2).
So the area of T is pi*(x*sqrt(2)/2)²=pi*x²/2
The area of S is pi*(x/2)²=pi*x²/4
And T/S = 2

Well, we do not know the formula for equilateral triangle. Let's find the formula of the area of the triangle first. Draw the high of the triangle. You have 2 right triangles. You have the hypothenuse t and half of the base 1/2t. You know that triangle which are 30°-60°-90° have side ratios like tha...
