<p>46/54</p>

<p>wow thanks guys :smiley: nice list… ill gather some questions and post them here once done :)</p>

<p>man, your answers is exactly the same as mine except for the “diameter is 1, 6 tangent circles” question…I think I got more than 6</p>

<p>what was e qn for 46/54</p>

<p>My sister mentioned the prime number question (p+k=28), as soon as she got home.</p>

<p>Though I don’t see, as I told her, why p cannot be 23 and thus k=5, in other words, p can’t surely be just 11 and 17</p>

<p>I just listed a possible pair of numbers, so I put 11 and 17 for now.
I see that 5 and 23 are another set of answers. I perfectly see that it is fully valid. Thank you for your contribution!</p>

<p>In what concerns the miles :
what was the question ?</p>

<p>someone ran for 2 miles from Mon to Fri and 5 miles for Sat. he skipped Sun. if he followed this regimen for n weeks then what is the total number of miles run by him</p>

<p>Ok thank you :slight_smile:
By the way ? can a 53 be a 800 ?</p>

<p>rarely. if the curve permit, then yes.</p>

<p>I remeber that there was a quadratic function with a b² - 4ac = I don’t remember wich one !! is it right ?</p>

<p>b² - 4ac = 0 !! right ?</p>

<p>experimental?</p>

<p>diameter is 1, 6 tangent circles. Perimeter = 6
WASNT IT RADIUS??? fuuucccccckkkkkk i got 12</p>

<p>The question about TANYA. Why do you think option 2 was wrong?
I don’t really remember the choice, but it only included a number out of the list, just as №1 did.</p>

<p>2 sqrt x = x^(y-1.5) + sqrt x –> y=2
is this one the grid in? i got 3,58??</p>

<p>two squares inscribed in the largest square; the smallest square’s area is 200.
what is the area of the largest? 800. ---- wasnt it 400??</p>

<p>distance between the midpts? sqrt 2. wasnt it 1? bc it was square8 -square 3???</p>

<p>Debt of Americans spread out in 1970 or sth was 16*10^3 hence n = 16
whheeeereee was this one??</p>

<p>parallel lines –> either 43 or 46, i don’t know.
i think it was 45… bc i rmember that there was a 46 and 91 and the opposite side was 46 etc 91-46
equilateral triangle with midpoint bisector was 30 degrees (not sure)
-dont even remember this one!</p>

<p>2011ivy, it’s definitely not 3,58, cause sqrt(x) = x^1/2</p>

<p>squares inscribed - i remember i got 800</p>

<p>wasnt the set question 2/10 ??? i made the stupidest mistakessss!!!</p>

<p>^nahhh 2/5…</p>
