<p>Which question was the 4x+5z+10z one? i dont remember it</p>

<p>Did people put 3/2 or 2/3 for the sphere and cylinder grid in?</p>

<p>i got 3/2…</p>

<p>I wish someone knew what the question was asking. I put 2/3 at first but changed it to 3/2 reading it several times.</p>

<p>I put 2/3. I could have read it wrong but usually it’s the ratio of the inscribed object to the outside object</p>

<p>if it asked for a fraction, it wouldn’t make sense to be 3/2.</p>

<p>It would have to say the ratio of the V of the cylinder to the V of the Sphere.</p>

<p>Ok so far the train time problem, it said that the watch was ahead, so you had to subtract 7 minutes from the clock time and them find the difference between that and what time the train was supposed to come, correct?</p>

<p>Sgt- it said something about fraction of volume of cylinder</p>

<p>So mad, I had 1.5 first, then changed it to 2/3.
And I got the angles question wrong, I wrote down 3. Additionally, I’m pretty sure I put down 54 instead of 80 for the chef salad question. Then for ordering from least to greatest I wrote (-1)^11. Again wrong. For the graph with the x-intercepts I put down zero. WRONG.
That’s five wrong already.
Math is my strong suit and now I’m failing it. What do you guys think the curve will be? Please Im freaking out!</p>

<p>what is the age cannot be 65 question about? I don’t remember doing it.</p>

<p>Math curve is going to be lenient. It was a really tricky math test compared to other SAT tests. I had to correct my mistakes on several problems. I’m pretty sure the angles question is 3. It asked for angles more than 90 but less than 180. You can have 3 91 degree angles but not 4.</p>

<p>@alaniet - I don’t remember it being age but it gave an absolute value / 2.7 <1?</p>

<p>I got only 65 for the absolute value one.</p>

<p>@ mpgh000 - Yeah, I completely agree. Math was tricky. And the answer for the angles question was 2. I put 3 like you did and had the exact same reasoning, but the correct explanation can be found a few pages back.</p>

<p>@division - could you give me the page # or explain? It said what is the maximum number of angles that could be more than 90 and less than 180</p>

<p>@ mpgh000 - dragooner4’s post on page 12 of this thread</p>

<p>@tonton Yes, that’s how you do the train problem. I think the answer was 26?</p>

<p>@alaniet I believe the question was something like abs( (h-68.5)/2.7 ) is less than or equal to one, and it gave 5 heights and asked which one was impossible.</p>

<p>can someone compile all 10 grid in questions?</p>

<p>@Extractum11 oh i remember now! i got 65 but i guess i didn’t read the question to remember it. Thanks!</p>

<p>Eh… the angle problems shouldn’t have been that complicated… It was near the middle of the section. I’ve never seen a question like the angle one in any other SATs…</p>

<p>Which angle one?</p>
