<p>33 numbers between 1-100</p>
<p>That 2x triangle was not equilateral: 2,4,6 :P</p>
<p>Would someone mind explain the “multiples of 3, 63 numbers left” one please? I put 7 as a random guess…would that work?</p>
<p>lol i switched it at the last second…silly old me…over thinking things too much</p>
<p>@brolex there are 33 multiples of 3 in 100</p>
<p>@rdpgn105 10/3</p>
<p>^again wrong, 100-33=67, 67-63=4</p>
<p>@defianced, correct :D.</p>
<p>but i still got the question wrong, damn 75 for being a multiple of 25, and 3 :(</p>
<p>Multiple of 3 question would be a number like 49</p>
<p>Trapezoid question was could not be determined</p>
<p>@goodatmath why 1/3?</p>
<p>@defianced LOL you’re right silly me can’t even add in my head</p>
<p>for the (0,0) (5,y) and (9,6) i got 3.33 for y because the lines equation is y=2/3x</p>
<p>Trapezoid question, I put 180-whatever the other angle was… I guess I’m wrong</p>
<p>why was the trapezoid question could not be determined?</p>
<p>so -2 so far, damnit!</p>
<p>@levinel me too! but i think we’re right because trapezoids have parallel sides so the interior angles on one side had to be 180…</p>
<p>The one that took me forever:</p>
<p>1-100, you take out multiples of 3 and n and are left with 64 integers. </p>
<p>There are 33 multiples of 3 so 100-33 = 67 So you need a number n that takes out 4 new integers.</p>
<p>I think i ended up putting 16. You need to consider that multiples overlap, but aren’t taken out ‘twice’ or whatever.</p>
<p>100-33=67 lol
so you needed 4 multiples from 1-100
there are several possible answers
I chose 19.</p>
<p>Its multiples would be 19, 38, 57, 76, 95</p>
<p>57, however, is already a multiple of 3 so that is already removed.</p>
<p>Therefore 19 removes 4 multiples leaving 63 integers left</p>
<p>17 works as well and there may be other answers.</p>
<p>Reason for could not be determined: Trapezoids only require one pair of parallel sides. we did not know the relationship between the two other sides</p>
