<p>can anyone does remember the answer to the problem where you have to subtract the area of a triangle from the area of a square? i got 40</p>
<p>yeah i got 40
what about that one about x and y
and it was like whats the biggest??? i put y^2</p>
<p>I found both the 1 and -3 points on the number line; they both worked for A.
I could have read it wrong I guess.</p>
<p>I got 40 and y^2.</p>
<p>Okay thanks haha I thought so but I was second guessing my answer since, iirc, the question came later in the section.</p>
<p>@concrete I got y^2 </p>
<p>Does anybody remember the circle question with the triangles in it? Or the one with the cylinder with the two cones in it?</p>
<p>I can’t remember the measurements for either one</p>
<p>the height was 12, and the radius was 4 i think</p>
<p>Y^2 was the answer</p>
<p>O<x<y<1
Plug in .6 for y, .5 for x if your not sure but answer should be apparent</p>
<p>40 was correct for the remaining area of the paper one. I put y^2 as the answer. I was plugging and chugging for that problem.</p>
<p>y^2
40
1440 - grid in
4/72 - grid in
509 - grid in</p>
<p>1/3r^2h
1/3 2^2 6
8pi + 8pi= 16pi</p>
<p>26 pencils</p>
<p>Triangle one=
Whole rectangle= 10x5= 50
Triangle = 5*4 1/2 =10 Don’t remember if 4 was given or if you needed pt
50-10=40</p>
<p>Vt, I got 30 pencils</p>
<p>30
1/2 + 1= 16
1/2-1= 7</p>
<p>I got 26. Half of that is 13+1=14.
26-14=12
Half of 12 is 6-1=5
12-5=7</p>
<p>no 26 pencils wasnt an experiemental</p>
<p>26 pencils</p>
<p>Bob took one more than one half so took 14, 12 left.</p>
<p>Joe took one less than one half so took 5, 7 left.</p>
<p>It was like person x took 1 more than half of the pencils, then person y took 1 less than half of the remaining half of the pencils. 7 Pencils remaining. How many did you start with?</p>
<p>Was it 30 or 26, wording was bad I remember</p>
<p>26
1/2 +1 = 14
26-14=12
12*1/2 - 1
12 - 5 = 7</p>
<p>i put 30, but its wrong. ughhh im so mad.</p>
