Try Kaplan 2005, they have 100 points for Math. Very helpful

By Sloan?

The book should include the CD, which has 5 tests in.

Which of the following integers does NOT have a divisor greater than 1 that is the square of an integer? (A) 75 (B) 42 © 32 (D) 25 (E) 12

10100=0.101 x 10^5, so it's C.:)

Make it simple, ignore 2,880,000, 717 is 3 minutes less than 720 (12 hours), so 6:27-0:03=6:24

D is the answer

B for support

The lowest doesn't mean the one lowest. Is this helpful?

In the second heat, A gives B a head start of 144 m and is beaten by 1/30 th of a minute. What is B¡¯s speed in m/s? (A) 12 (B) 14 © 16 (D) 18 (E) 20 3. The co-ordinates of the foot of the perpendicular from the point (2, 2) on the line y ¨C 2x ¨C 8 = 0 are (A) (¨C1, 6) (B) (¨C1, ¨C4) © (¨C2, 10) (D) (2, 4) (E) (¨C2, 4) 4. A certain quantity of 40% solution is replaced with 25% solution such that the new concentration is 35%. What is the fraction of the solution that was replaced?

A 3.E 4.B 5.C 6.D 7.B

1C2x1C2x1=4

It should be D. Since profit=revenue-cost=17n-(F+11n)=6n+F

Prime number has to be positive, the smallest prime is 1, so i think it should be C. Let me know if i am wrong.

It doesn't matter as long as both statements are suffcient to prove the average not equal to 5/2R

Sorry, i do not know how to do it either, could you tell me sine you're clear with it. many thanks!
