<p>on average... how many can you miss to get nms</p>

<p>It depends on the state you live in because each state has a different score.</p>

<p>Ok.. thanks</p>

<p>does anyone remember the multiple choice question involving 4t when (6t+7a)/4=t?</p>

<p>I think -14a was what i got.</p>

<p>Solve for t: t= -7/2a then multiply by 4 and get -14a.</p>

<p>alright thats what i had too, thanks</p>

<p>Yeah, except for the quadrilateral one, I got 3. I don't remember exactly, but I think I didvided it into a big 2X4 rectangle, and subtracted the triangles within it that were missing. Also, for the train one I put 1,600.... now I'm mad...</p>

<p>For the circle one, I put 2.87 or something along those lines.
The question was: A wheel spins 3,000 times and covers 45,000pi inches. What's the radius of the wheel?</p>

<p>Well, if we take 45,000/3,000 as most of you have suggested, wouldn't that be its circumference? I did that, and then solved for r (C=2(pi)r)
Was that wrong?</p>

<p>The one with the word "sidestepping" I vaguely remember putting an answer that divided into two sentences. </p>

<p>Okay, this one killed me, and I know it's easy so I hate myself for not knowing the answer. The question was "Which of the following could be the sides of a triangle?"
I don't remember the choices, but I put D, I think.</p>

<p>Dividing 45000/3000 gives you the diameter. You could have written 2(pi)r = 45000pi/3000 and the pi's would cancel out leaving 2r=15.</p>

<p>What do you think I would get if I skipped 2 questions on the math and got 1 wrong?</p>

<p>I skipped both the ones with the 4 variables and ordering from least to greatest..
I got the one about rst wrong as well...</p>

<p>WOO awesome! So far the posted fill in the blank questions for math 2 were all what i got =)</p>

<p>"Okay, this one killed me, and I know it's easy so I hate myself for not knowing the answer. The question was "Which of the following could be the sides of a triangle?"

<p>I think I put D too, it was the one that was like 7,8,9, because all the others, the 2 smaller sides added together were smaller/equal to the 3rd side, which doesnt make a triangle.</p>

<p>Chip90, that's 38-3.25= 34.75 which rounds up to 35 points and if you use this years bulletin test scale, that would be a 70. But the scale might be different.</p>

<p>Also something that got on my nerves was that 3 people in my grade got extra time to take the test because of a "learning disability" which gave them 50% extra time to take the test. Thats 13 minutes extra on each section! And the bad part is that none of them REALLY have a disorder...</p>

<p>My friend has vision problems so they give him the newspaper sized SAT + extra time.</p>

<p>That is not as bad as a deaf girl in my class getting extra time on tests.</p>

<p>What were the questions for the grid-ins where the answers were 9, 120, and 18? I got similar answers for the rest but I don't remember these questions, lol...</p>

(not drawn to scale)</p>

<p>This is how i did the quad problem on my test.
-First, I split it up into a large triangle and a trapezoid.
-Using the x coordinates, you could see that the two bases of the trapezoid were 3 for the large base and 1 for the small base.
-Using those two lengths, you could see that the bases of the triangles would be 1.
-With this information, you can calculate the area of the trapezoid by adding the areas of the two small triangles and the square
1/2bh= .5
1/2bh= .5
1squared= 1</p>

<p>= 2</p>

<p>Now, all that's left is the large triangle. The entire base is 3, and using the y coordinates you could see that the height of the triangle is 1. (The red dots on my image indicate that the length was determined using the coordinates of the graph).
1/2bh= 1.5</p>

<p>Then you just add the trapezoid and the large triangle together...
2 + 1.5 = 3.5
hooray!</p>

<p>What were the questions for the grid-ins where the answers were 9, 120, and 18? I got similar answers for the rest but I don't remember these questions, lol...</p>

<p>18 was the student one where you had s students and m microscopes, and if you gave 1 microscope to each student, you would need 6 more, but if you double your microscopes and give 1 to each student, you would have 6 left over</p>

<p>120 was the triangle where it said two sides were equal and it said one of the angles was 30 degrees. So you had an isoceles triangle, and just subtract 180 - 60</p>

<p>I think 120 was the triangle problem where you had to find the angle.
I think 18 was the students/microscope one.
And I can't think of the 9 one.</p>
