OE [spoiler]sqrt(2)*s[/spoiler]


3) What is the greatest possible area of a triangular region with one vertex at the center of a circle of radius 1 and the other two vertices on the circle

OE [spoiler]1/2[/spoiler]


4) If x is not equal to -y, is (x - y)/(x + y) > 1?

1. x > 0
2. y < 0

OE E


5) In a certain year the UN's total expenditures were $1.6 billion. Of this amount, 67.8 % was paid by the 6 highest-contributing countires, and the balance was paid by the remainin 153 countries. Was Country X among the 6 highest-contributing countries?

2. Country X paid 4.8 % of the total expenditures.

OE E


6) If 500 is the multiple of 100 that is closest to x and 400 is the multiple of 100 that is closest to y, which multiple of 100 is closest to x + y?

1. x < 500
2. y < 400

OE E

I don't even understand what this question is asking



7) If k is a positive integer, is k the square of an integer?

1. k is divisble by 4.
2. k is divisible by exactly four different prime numbers.

OE E


8) If (-) denotes one of two arithmetic operations, addition or multiplication, and if k is an integer, what is the value of 3 (-) k?

1. 2(-)k = 3
2. 1(-)0 = k

OE A

(My thinking: (1.) 2+1 = 3, therefore k = 1. So 3(-)k = 3+1 or 3*1. Insufficient(2.) k = 1 or 0. So 3(-)k=4 or 0 Insufficient. Together also insufficient)


9) Is |x| = y - z?

1. x + y = z
2. x < 0

OE C
