<p>I am fairly sure that the number of triangles created by drawing lines from point P on an octagon to the other vertices was six, not seven.</p>
<p>I got 100 for the equilaterals...since each repeating part was essentially 4 inches, but the actual EDGE was 5 inches. 3 inches + 2 inches from the triangle. 5 inches times 20 is a hundred, right?</p>
<p>for the equilateral; it was 100
since the entire length was 80 and they divided into 4 so we had 80/4= 20
the new perimeter or bolded line for each section was 5. so 5x20=100</p>
<p>do you mean 100 for the chopped wood problem?</p>
<p>aston 722 it is a equalateral triangle so the "cut" is 2 in plus the 3 in=5 in. and there are 80/4=20 sections. 20x5=100 in. =]]]</p>
<p>they have you a strip with a total STRAIGHT distance of 16 inches. therefore, there were FIVE strips, so you had to multiply the number by 5. If you counted the rubber part, you would get 18. so you multiply 18 by 5 and you should get 90.</p>
<p>Battlecruiser, it was ninety degrees.</p>
<p>****, the answer was 6
i think for some reason i thought 5+1 = 7
I hope i didnt do that and did write 6 >_<</p>
<p>wow that paper one totally went right over my head. durrrrr</p>
<p>How bout the one with with the 8 sided figure and the diagonals how many triangles did it result in?</p>
<p>I put 6</p>
<p>Also for the quesstion with 6 points, no three points on the same line I got 15 lines</p>
<p>yea 6 was the answer</p>
<p>Damn.. got 3 grid in and 1 math wrong already.... :( :(</p>
<p>wait can someone resolve the paper one, is it 90 or 100?</p>
<p>Ptang I wrote 5 as welll.... </p>
<p>Oh wel.. I guess I'd better forget the 750 I wanted :( :( :(</p>
<p>how bout the last grid in question? the one with the graph of the square, and it asked you if y=ax^2, what is the value of a? i put 1/2, i don't know if it's right...</p>
<p>no1mtsfin yup 1/2 is right..everyone already confirmed that in another thread</p>
<p>It is 100 inches. Since it was eighty originally and the notches were every four inches, you can deterimine that there were twenty nothces. Since it is an equilateral triangle [you can also draw an altitude and use 30-60-90], each side of the triangle was one. Therefore, the length was five inches for every four inches of the original. Five times twenty is 100.</p>
<p>well since half the square had an area of 32 because one side is 8, than that means 8x=32, so x is 4. so i think 1/2 is right</p>
<p>what was the 8 sided figure questions asking was it the number of diagnals or triangles that formed</p>
<p>that one stumped me, no iddea</p>
<p>the number of triangles</p>
