sat math question

<p>2 things first of all</p>

<p>if i omit every single hard question out of the 54 questions the math section has </p>

<p>altho i wont omit every one by january just hypothetically</p>

<p>can i still get 650+</p>

<p>also
i dont understand how to do \
pg. 807 blue book math section 8
numbers #15 and #16</p>

<p>bump plz any1 cmon</p>

<p>i dont get these angle problems</p>

<p>Nobody here can tell you if you can get above a 650 omitting all the hard problems. We a) don’t know how many of these problems will appear on the Jan. test and b) neither we nor you know how many other mistakes you will make. If you were to omit every hard question, you would end up omitting about 15 or so questions depending on how many hard questions there are (it varies a little test to test). Say you omit the 15 hard and get all the other questions right, you would be looking at about a 580-620.</p>

<p>As for those problems, I can’t really help you because I have the BB2. But if you want to tell me what Practice Test # they are from in the BB, I can help you out.</p>

<li><p>This is sort of difficult to explain w/o a visual, but here it goes: The answer is D.
You have to see that all the angles measured are parts of right triangles with one
side as XY (thus, this is constant for every case). We need to find the tringle with
the longest hypotenuse in order to find the smallest angle. The longest
hypotenuse is XD because the longest leg (other than XY) is DY (the diagonal of
the square). Therefore, Angle XDY is the smallest. If you still have trouble
understanding this, draw out a couple of different right triangles, keeping one leg
in all of them constant and changing the lengths of the other. Then compare the
angles formed by the hypotenuse and variable leg.</p></li>
<li><p>xy = 7, x - y = 5, What is (x^2)y - x(y^2)?
When you multiply xy with (x - y) you get: (x^2)y - x(y^2)…which is what you
need to find. So (xy)<em>(x - y) = 7</em>5 = 35. The answer is D.</p></li>

<p>I hope this helps!</p>
