November 2010 SAT - Math

<p>future, 610-640.
Why omitted so many?</p>

<p>Merry go round: 95
Get 7 green: 37
Original avg 15 new avg 19 : orignial sum - 75</p>

<p>Two digit int with greater first digit: 1+2+3… +9=45</p>

<p>a, 2a+1… : 101 or something like that</p>

<p>John and tom : x=t
F(4) + f(1)=11</p>

<p>Was the 2a+1 D?? Because thats what i remember i put</p>

<p>OMG 81 for the win! I guessed 18 but then looked at the answers and thought about how, if the answer is a square (81), they always put the square root as one of the answers (9). So I changed it to 81. lol @ guessing strategies</p>

<p>Starting to feel like I should have just done more smart guessing than trying to solve the problem… thanks to a week of practice I knew how to solve the problems but wasn’t practiced enough to 100% surely get the RIGHT answer. I’m getting so many wrong compared to the last time when I just guessed like crazy and ended up getting a lot of them right, LOL. /irrelevant</p>

<p>@ webass a lack of time caused me to omit so many. Do u think da curve will be generous ?</p>

<p>what was the context of the x + y +z =240 problem? i dont remember it</p>

<p>Wasn’t the answer to the 101 problem actually x=100, because the formula was x+1 and you were trying to get to 101?</p>

<p>@ DIPOLE</p>

<p>3 Congruent triangles. Sides are 90 degrees and 35 degrees. Arranged in a circle. Find the space between the angles.</p>

<p>hm i really don’t remember that…did you have an experimental? I had the form with the one with 37 cards for the green one.</p>

<p>@deadmasterr

</p>

<p>one machine finishes in t hours the other finishes in t/12. if it takes 12 hours for them to finish combined, what does t equal.
I put 36 which was answer E. </p>

<p>(1/36+1/18) is one hour. so (1/36+1/18)*12hours = 1 task complete</p>

<p>Nope. I got the cards one too.</p>

<p>do you guys think the curve will be generous? please respond</p>

<p>for the 2 squares and circle problem i got</p>

<p>1<x<3/sqrt(2)</p>

<p>all triangles are 45-45-90. so triangle with hypotenuse of sqrt(2) has side length of 1 and triangle with hypotenuse of 3 has side length of 3/sqrt(2). since the circle cannot touch either square the radius must be between these two lengths.</p>

<p>Futuresuccess, I don’t think so.</p>

<p>Actually, its 1<X<1.5</p>

<p>what was the one where it was like:
how many 2 digit numbers are there where the tens digit is greater than the ones
I thought 45 but someone said 36. Isn’t it: 10, 20/21, 30/31/32 etc.? therefore there should be 45. Did I fail to read something like the fact that the digits have to be positive></p>

<p>Some more answers (for the other version of the test):
5 for the circle touch the pentagon
II and III for the equations that intersected the parabola twice
1/5 for the probability of picking a black chip a second time</p>

<p>pookie, why dont u think the curve will be generous. This test was hard!</p>

<p>do you guys think there could be a -1= 800 curve on this one?
EDIT: I’m talking about the test with this question:
One pump drains a pool in t hours. Another pump drains the pool in t/2 hours. Together, each working at full capacity, they drain the pool in 12 hours. What is t?
(As there are apparently more than 1 test out)</p>

<p>Probably not. The questions were TRICKY, not hard.</p>
