ACT...Oct 23rd Official Thread

<p>I took the ACT today, too, and I think I did ok. I've taken it three times before today's test. The first time, I made a 25; second, 26; third, 27. I really hope I score higher than a 28 this time. I actually feel like I understood the questions better this time. Maybe that's a good sign? Oh well. We'll all find out soon enough! (Though, some sooner than others. I wish that online score service was free!!)</p>

<p>xy=3</p>

<p>(x+y)^2 = 10</p>

<p>How many real solutions? Infinitely many?</p>

<p>No real solutions</p>

<p>No solutions. Could someone please explain the ratio question with the traingles and square. Don't just say look at the picture, because for some reason I did something and it came out to 1:2.</p>

<p>I said rectangle earlier, although I believe it is a square... Not totally sure, and either way it doesn't matter.</p>

<p>But if I remember correctly, there were four lines each with endpoints at the midpoint of each of the four sides of the square/rectangle. If you cut the rectangle/square into four pieces, each one of these four lines went through each square perfectly splitting the square diagonally... So each square was split 1:1 which makes the entire square split 1:1.</p>

<p>It's hard to explain online, but I'll try...I'm pretty sure the ratio is 1:1. </p>

<p>On a piece of paper, draw a square. Now draw another square within the original square so that its verticies touch the outside of the original square (it will be a square but placed like a diamond). That is what the picture looked like. Now to help you visualize the ratio of the triangles and the square itself, draw a line vertical and horizontal through the square, doesn't matter which one. You will see that the area within the smaller square is equivalent to the area of the four triangles.</p>

<p>Hope that helps!</p>

<p>When do ACT scores come in the mail?</p>

<p>3-4 months</p>

<p>Geez I thought it was weeks... </p>

<p>Does the ACT curve?</p>

<p>Just kidding... They said before 7 weeks although presumably much sooner.</p>

<p>I was really disappointed with my performance on the ACT this time! My first time I got a 31, which was fine with me, but I thought I'd give it one more shot after having more math, etc. The practice test went well - got a 33 on it and was able to time all the sections decently at home. At the real test, I felt like the test was harder than the practice and that I just could not pace myself...</p>

<p>The ACT has a predetermined scale, right? I think for basically everyone you miss, at least at first, you lose a point (at least in the science section). I just feel like this test was harder than the last one I took...Anyone else?</p>

<p>Ughhh, I had to fill in pure guesses on both the reading and science out of loss of time. It all went pretty bad. Is it worth canceling if you think you did worse? Or will the colleges ONLY look at the top score and not even be affected by a second time lower score? Opinions please!</p>

<p>They come in a month, and thanks Leonesa. I did something stupid like assign a value to the side of the square and then use x, x, xsqrt(2) to get the length of the triangle side. wow</p>

<p>hey I think I got a totally different test.. anyone had a story about a deaf and a blind person? a cat?</p>

<p>Damn I flew through this one and was able to check over my answers on all sections.</p>

<p>No prob... Don't you hate when you go to great lengths for something that is really just simple? I do that all the time!</p>

<p>Wish I could say the same douche! :(</p>

<p>The sides of the triangles (on the outside) can be labeled as x. Then using 45-45-90, the sides of the square are all x<em>rt(2). the area of the square is s^2, or (x</em>(rt2))^2 or 2x^2.</p>

<p>Area of square = 2x^2</p>

<p>Next, the area of a single triangle is 1/2<em>b</em>h or 1/2<em>x</em>x = 1/2<em>x^2.To determine the area of the four triangles, just multiply by four: 4</em> 1/2*x^2, and get 2x^2.</p>

<p>Area of triangle = 1/2*x^2
Area of 4 triangles = 2x^2</p>

<p>Area of Square/Area of Triangle = 1, thus a 1:1 ratio</p>

<p>"hey I think I got a totally different test.. anyone had a story about a deaf and a blind person? a cat?"</p>

<p>Nope....</p>

<p>I KNOW WHAT I DID! I messed up the area of a triangle formula. That is absolutely horrible. I did bh instead of 1/2bh. I hadn't used the formula since 3rd grade, and I messed it up!</p>

<p>xy=3</p>

<p>(x+y)^2 = 10</p>

<p>How many real solutions?</p>

<p>I put 2 solutions for this... why aren't there any?</p>
