1.- Quantitative comparison x > 0 A. Volume of cube with side x B. Volume of rectangle with length x/2, width x/2, and height 2x 2.- Problem solving A rectangular solid is twice as long as it is wide. The height of the solid is the mean of the length and width. What is the ratio of the length to the height of the solid? A. 2:3 B. 3:1 C. 3:2 D. 3:4 E. 4:3 Thanks for your help! Emily

so what's the final verdict? which test has the harder section(s)? i am studying for my GRE using a GMAT prep book, (math only). is this a good idea?

I was able to sort of guess the correct answer, but I don't understand the logic behind it... 30% of Canadian families have a dog. 30% have a cat. 50% have neither a dog or a cat. How many have both a cat and a dog? (A) 0% (B) 10% © 30% (D) 50% (E) 60%

I'm a former music major trying to get into grad school, so forgive my ignorance when it comes to these math problems. Would love to get some help with this one too... A bank customer borrowed $10,000, but received y dollars less than this due to discounting. If there was a separate $25 service charge, then, in terms of y, the service charge was what fraction of the amount that the customer received? (A) 25/10,000 - y (B) 25/10,000 - 25y © 25y/10,000 - y (D) y - 25/10,000 - y (E) 25/10,000 - (y-25)

Could use some help with this one too. If x and y are nonzero integers, is x/y an integer? (1) x is the product of 2 and some other integer (2) There is only one pair of positive integers whose product equals y

I have no idea how to tackle this one... If each of the following fractions were written as a repeating decimal, which would have the longest sequence of different digits? (A) 2/11 (B) 1/3 © 41/99 (D) 2/3 (E) 23/37

Just realized I might have posted this in the wrong place... I'm a former Music major trying to get into grad school. I'm an idiot and bought a prep book without explanations. I have a bunch of problems I'll be posting with the hope of getting some help. Here's the first one: Is p2 an odd integer? (1) p is an odd integer (2) root-p is an odd integer
