<p>may sound dumb but if the temp is < -160 it wont work for D</p>
<p>it should read

Lori will not use steamed milk that is above 170 degrees

<p>hello harvardbound,no offence,why are u using such a long process like solution no.1? according to SET ALGEBRA METHOD,solution 2. is more than ok.</p>
<p>IMPORTANT:</p>
<p>i can provide some more FORMULAS for you</p>
<pre><code> A) A u (B u C)=(A u B) u (A u C)
B) A n (B n C)=(A n B) n (A n C)
C) A u (B n C)=(A u B) n (A u c)
D) A n (B u C)=(A n B) u (A n C)
E) (A u B)'=A' n B'
F) (A n B)'=A' u B'
G) A - B=A n B' (A \ B= A n B')
H) A x (B n C)=(A x B) n (A x C)
I) A x (B u C)=(A x B) u (A x C)
(by the way, formula no. E and F is called DE MORGANS LAW)

<p>if anyone of you need to help any particular math theory,just let me know,i shall try my best to solve your problem......again,pardon my english good luck to u all in math

<p>When making a latte, Lori will use steamed milk that is above 170 degrees, since if she uses under 170 degrees, it will not boil.--------------i think this is more correct</p>
<h1>24) When making a latte, Lori will use steamed milk that is above 170 degrees, since it will not boil. She will also not use Milk that is below 150 degrees, since it will not foam. If t represents the temperature of steamed milk, in degrees, Fahrenheit, that she will NOT use, then an inequality that represents all possible values of t is :</h1>
<p>A) |t - 170| > 160
B) |t - 160| > 10
C) |t - 150| > 10
D) |t + 170| > 10
E) |t - 160| < 10</p>
<p>Ans: B</p>
<p>i seriously don't understand,why will u use -160 as a test choice when its already told that she cant use milk of under the temperature of 170.so whatever figure u want to choose to test these answer choices,that MUST be bigger than 170</p>
<p>for f(x)= x^2-2, the easiest thing to do would just plug-in values...0 makes it (0, -2) while 4 makes it (4, 14)..that means the range is [-2,14] and any value NOT within that set makes the statement false... sooo</p>
<p>1) plug-in or graph.
2) find the value that does not fit</p>

<p>did you write this problem wrong?</p>
<h1>24) When making a latte, Lori will use steamed milk that is above 170 degrees,*** since it will not boil***. She will also not use Milk that is below 150 degrees, since it will not foam.

<p>Ans: B</p>
<p>Common sense tells me that if the milk is above 170 degrees it WILL boil- and the second sentence does not fit in with the first. She will "also not use milk" that is below 150 degrees", but the 1st sentence is telling me she will use milk that is above 170 degrees? did you forget the "NOT" use milk above 170 degrees? because it's basically unsolvable as the way you worded it. </p>
<p>now...to solve it with "NOT"...</p>
<p>Lori will NOT Use milk above 170 degrees and will NOT Use milk under 150 degrees.</p>
<p>therefore, you're going to test values UNDER 150 degrees and values OVER 170 degrees.</p>
<p>(A) use T=171. it does NOT satisify the inequality. eliminate it.
<a href="B">B</a> This is the answer. use t= 149, or t= 171, and you get 11. plug in ANY number under 150 or over 170 and this will work. this is the answer.**</p>
<p>(C) plug in t= 149, and this does not work.
(D) you might be tempted to choose this, but remember u can use negative values here too. plug in t=-170 (which is within our ranges), and you'll find out this is wrong.
(E) use t=171, and this answer is eliminated.</p>
<p>i have used the same method.it doesn't need graphing</p>
<p>JexteLox, I copied it exactly the same. Thanks for these problmes everyone.</p>
<p>OH....ok...confused me there...yeah so the 170 degree part is irrelevant to the understanding of the problem, all you need are values under 150... sorry , lol, never seen a problem like that on the sat {did u find these in the blue book?}</p>
<p>no, not BB, but i got it from PR and I have seen these pop up before though like in Kaplan, or Barons etc</p>
