<p>Marcia makes and sells handcrafted picture frames in
2 sizes: small and large. It takes her 2 hours to make a
small frame and 3 hours to make a large frame. The shaded
triangular region shown below is the graph of a system of
inequalities representing weekly constraints Marcia has
in making the frames. For making and selling s small
frames and l large frames, Marcia makes a profit of
30s + 70l dollars. Marcia sells all the frames she makes.</p>

<p>QUESTION:
What is the maximum profit Marcia can earn from the
picture frames she makes in 1 week?</p>
<p>ANSWER: $560</p>
<p>you have to read the graph…
if one week if she only makes large (l) frames… she will be able to make 8.as the graph says…if she makes 8 large frames, she wont be able to make any small ones.
the cost of each large frame is 70</p>
<p>70x8 = 560</p>
<p>you could try different combination by using different points on the line graph to and eliminate the other choices.</p>
<p>Oh…I see. I was counting both.</p>

number 44: I thought circles had unlimited symmetry? help?
47: how do you do this?</p>
<p>44 isn’t just a circle…it has 2 squares inscribed in it so u have to account them as well…</p>
<p>47 - bisect means that the angle is divided into half…</p>
<p>AE bisects angle BAC …and BAC is 82. that means 82/2=41…so 41 is one of the angles in the triangle…</p>
<p>AB and CD are parallel lines… when a straight line cuts them…the angles formed will equal 180…
therefore, angle BAC + angle DCA = 180
that is 82 + angle DCA = 180
hence angle DCA = 98</p>
<p>CE bisects DCA…so the 2nd angle in the triangle is 98/2 = 49</p>
<p>now look at the triangle… all 3 angles should equal 180…we have 2…41 and 49 = 90…soo the remaining is also 90 ! :)</p>
