SAT May 2009 Math

<p>they asked for tin not copper the answer is 1 for the tin/copper thing.</p>

<p>The ratio of copper to tin was 19:1 and 380 pounds of bronze was made. Therefore, 19x+x=380. x equals 19; and 19 would be the amount of tin. It was a really simple question.</p>

<p>In the inequality one, it said “The difference between A and B is not greater than 6” right? So wouldn’t the answer be abs(a-b) is greater than or equal to six?</p>

<p>^ was slightly confused by that one too…</p>

<p>Did anybody get 2.5 for an answer? I think it was the “how many cups of flower for 5 cupcakes” or sumthin…</p>

<p>@10jarsle: It was |a - b| <= 6 because if it’s NOT greater than 6, that means it has to be less than 6…or equal to it.</p>

<p>and yea i got 2.5 for the flour one.</p>

<p>i loved the question about gorilla and lion years :)</p>

<p>ohh yea that was (3/4)x right?</p>

<p>how about that one with the two patients and they both are given medicine at 10 AM and one is given every 6 hrs and the other is given again every 4 hours, at what time will they both be given medicine at the same time?</p>

<p>oh and there was a sequence one, like the next term is determined by halving the previous and adding 2. what is the fifth term in the sequence?</p>

<p>^ i think that two patients one was experimental.</p>

<p>the sequence one was like 4.5</p>

For one with a,b, and c, was a I,II,III type question- I and II only
Flour for cake making (1.5 lb = 3 cake, how much flour for 5 cakes): 2.5
Lion: 3/4x</of></x<2></p>

<p>^^^
Two More:
Flour: 2.5
Lion: 3/4x</p>

<p>How did the area of the two triangles question go?</p>

<p>what was the flour one?</p>

<p>you had like a sideways kite, and it was divided into 2 triangles. You were given the numbers 4 and 3 for one triangle, and the hypotenuse (13) and one leg (12) of the other triangle.</p>

<p>^ the flour one was a grid-in i think like the 2nd problem. it was a proportion, and said you need this amount of flour to make this amount of cake or something, how much flour do you need for <em>amount of cake</em>…</p>

<p>oh, right. I remember.</p>

<p>^^^ okay yea I remember now. Thx.</p>

<p>did anyone have this one (might be experimental)
with the pie percentage chart and three sections (x, y, and z), and it asked about plumbers that were recommended?</p>

<p>sounds like experimental.</p>

<p>Nope it is probably exp.</p>

<p>If anyone remembers, could you try to restate what the question was for “calculus is wednesday.” I remember that my answer included the word “physics” but since you all got “calc/wed” i guess im wrong.</p>

<p>also, what would my score possibly be with -2 on multiple choice and -1 on grid in?</p>
