GMAT Prep - Quant Questions Missed - Pls Help [#permalink] New post 10 Nov 2006, 15:31
Hi All,

Just took my first GMAT Prep practice test and scored a 620 (41V, 32Q).

Some of the quant questions I missed that I could not figure out after reviewing are attached. ANY HELP you can provide regarding the correct solution is appreciated.

I will definately return the favor as I improve!

THANKS :-D

Q -3

box 9 = 27
box 6 = 3
box 9* box 8 = 81 = box 27

Q-5

angle abc = 90 degrees
u know BC and AC as 1 and 2 respetively
so u can find AB

q-7

angle ADB = 180-2x
therefore angle ABD = 180-x -(180 -2x)
=x
so AD = BD but we know know BD = BC so only A is necessary

(1/5)^m*(1/4)^18=(1/(2)(10)^35
What is m
TAking evrything to numberator
5^-m * 2 ^36 (using 4=2*2) = 2^-1 * (2*5)^-35 (using 10=2*5)
=>2^-1*2^-35*5^-35
5^-m*2^-36=2^(-1-35)*5^-35
Cancel out 2^-36 from both the sides
5^-m=5^-35

-m=-35
m=35

9/37

A. Greater than 16 ft/sec = (30 mins * 60 secs * 16 ft = 28800 ft) to infinite Insuff
( since 5280 * 6 = 316800 is in between28800 and infinite )
B Less than 18 ft/sec = between 0 and (30 * 60 * 18 = 32400) Insuff

A & B put together tells us that he cycled between 28800 and 32400 ft which doesnt tell us if it is less than or greater than 6 miles

so E

11/37

break it down to the prime factors

990 = 10 * 99 = 2* 5 * 11 * 9

so the n should be atleast 11

18/37

plug in some values say x= 3, 1-3 = -2 and solve for both 3 and -2 in each of those functions. I cant think of any easy way as I am not good either.

At what speed would he need to go to travel exactly 6 miles in 30 minutes?

6*5280 feet in 30*60 seconds= 5280/300 ft/sec, which is between 17 and 18 feet per second
