<p>what’d you guys for the one that asked for 0.00000897 in terms of 10th powers… the wording was quite confusing. it asked for 0.00000897 for what power of 10 and the selections were 10^-7 which means if i selected that 0.00000897 would be 10^10^-7?</p>
<p>@science4: there were two ways to do it. Once was if 0=0 for the equations it would be infinite. Other way would be to recognize if you multiply the top equation by 3, both equations would be equal. The right side constant was 45 so 5n. n = 9</p>
<p>thanks, do you remember what letter 9 was?</p>
<p>YES. i think the only one I missed was tan-1(3/25). the sun in the well thing. can anyone explain it to me? I ended up just choosing A and moving on to the other ones.
@science4 it was B for sure, at least on my form. A was 5 B was 9 i remember that.</p>
<p>The answer was 6/77, yes.
There was a clock question right? How an hour for the hour hand was 30 degrees?
What was the angle it moved when it moved from 6:00pm to 6:40-something pm? 21 degrees?</p>
<p>@starchywinky yeah 21 degrees. 1 hour/30 = .7hour/x solve for x ^^
man im feeling sexy. 99% sure I got 36 on english, missed only one on math so 35, reading was a cinch too, and science I maybe missed 2. Hopefully 35!!!</p>
<p>The angle was in the top left. You only had the opposite and adjacent sides of that angle, so you use Tangent. SOH CAH TOA ftw.</p>
<p>You wanted to find the angle of the sunlight coming in to the well. the sunlight creates a right triangle with the well. You would use a tangent because the values you could use were opposite and adjacent, remember SohCahToa? Tangent: Opposite/Adjacent</p>
<p>Anyways, the width of the well (opposite leg) was three, and the height of the well (adjacent leg) was 25.</p>
<p>To find theta (the angle you’re trying to find), you need to use an inverse tangent, so Tan-1(3/25)</p>
<p>hope that helped!</p>
<p>Wow… I got the systems one wrong too. Down from 36, to 35, to 34/33 depending on the curve. No es bueno.</p>
<p>So far, only missed one (stupid mistake too! D: ) so 35? I’ll take that very gladly.</p>
<p>hey @itsthebballer</p>
<p>that question asked for 0.0000897, so it would have been 897 * 10^-7.</p>
<p>I think I put 9 for the systems one! :’) Okay, so I think I got a 34 on the math, 34 on English, 27 on reading, and 30 on science. decent.</p>
<p>Does anyone remember the specifics of the systems question?</p>
<p>the second equation must be the same as 3 times the first equation.</p>
<p>I think it was
2x+3y=15
6x+9y=5b</p>
<p>Even if I have the exact coefficients wrong, the important thing is that you realize theres a factor of 3 involved and that you get 9 for b.</p>
<p><a href=“x%5Ea”>quote</a>(y^a) = (xy)^a
[/quote]
</p>
<p>Shouldn’t it be (xy)^2a (multiplicative property or whatever, doesn’t it say when you multiply exponents you actually add them)? That’s what I put. If that one’s wrong then I got 5 wrong which is way better than I thought I’d get (I’m awful at standardized math).</p>
<p>Based on past tests, would a -5 on math still get me a 30?</p>
<p>no, it was (xy)^a because powers are factorable. it would be to the power of 2a if x = y, and that would look like x^2a</p>
<p>@Dsus - ah, I remember it now. I wasn’t thinking and put b=5 so the two equations would be equal to the same thing. Now that I look back I realize I couldn’t have been any more careless. So stupid >.<. Two questions wrong is probably a 34 or 33… oh well.</p>
<p>I would just like to say that the math this time around blew my mind. Those were not made for a 60 minute test. Math isn’t my best subject but I’m in college trig, the concepts on there were like algebra 2 stuff and for some reason I just blanked. SAT math ftw.</p>
<p>@also for the line over 481719 or w/e one. All you had to do was 135/6 = 22.5 This means if you times 22 x 6 (the digits in the pattern) you would get 132. Thus the 132th digit is 1 i think. then you would just move 3 up to get the answer. i think it was 8.
Always helps to take a step back from a hard problem and think of how an idiot would approach it.</p>
<p>Yeahhhh didn’t miss ant yet what was he keeps and beeps I think I got b</p>
