<p>I got 36 for the perimeter of the triangle</p>
<p>If I put .111 in the question where the answer is 1/9, will i get it correct or wrong?<br>
Could you also remind me the task about the area of quadrilaterial? I don’t remember what number i got there.
And how did you do the task about “student that are in both of clubs” or smth like this.
Thanks.</p>
<p>Decimals are fine, you can even round 2/3 to .667 etc</p>
<p>as for “15/2 for the hose question”, what was the question? i don’t remember what i put there… :(</p>
<p>hey can anyone explain why the three consecutive numbers questions is 1/12 ? </p>
<p>i put 1/6 for some reason… </p>
<p>thanks:)</p>
<p>@amisnow, 1+2+3/17+18+19 = 1/9.
1/12 is the answer to some other question, smth about probability.</p>
<p>Dart, it was the question that was like. A hose can fill a bucket in 4 minutes, if it fills another bucket in 30 min, how much bigger is the bucket? Answer is 30/4 or 15/2 or 7.5</p>
<p>there would be like 24 different situations(list them out or 4<em>3</em>2*1=24)
and the two possible situations that meets the requirement is (1234) and (4123)
so that’s 2/24=1/12</p>
<p>that graph with money made compared to bonus is 3250</p>
<p>i remember the pic is 0~30000->1% then the % rise 1 per 10000</p>
<p>the man made 65000 and the corresponding % to his last 5000 should be 5%</p>
<p>so i worked out 1450</p>
<p>which part did i make a mistake?</p>
<p>@PyroDave, good, i did it right! the last task i can’t remember is about the area of quadrilateral, anybody has got the data for this?</p>
<p>Do you guys remember if 7 was an answer choice for the question whose answer was “8 kids in both clubs?” thanks!</p>
<p>does any1 remember how the “8 kids in both classes” question was asked? im not sure if i put 8 or 11 and i cant remember the problem</p>
<p>15 in club A, 12 in club B, 11 in only one club.
I got this one wrong, but the method to do this was 11+12-15=8.
I think 7 was an option but I’m not sure. I know 16 was, because I did 15+12-11 instead.</p>
<p>According to a post on here:-
“11 kids are just in one club
15 kids in debate, 12 in the other one”</p>
<p>Let A and B be the sets of students in each club.</p>
<p>So, if ‘n(S)’ is the cardinality of set S,</p>
<p>n(A int. B) = n(A) + n(B) - n(A U B) — (usual rule)
=> n(A int. B) = n(A) + n(B) + (n(A - B) + n (B - A) + n(A int. B)) — (since A - B, B - A and A int. B are disjoint)
=> 2 * n(A int. B) = n(A) + n(B) - n((A int. B)‘) — (taking the A U B to be the universal set)
=> n(A int. B) = (n(A) + n(B) - n((A int. B)’))/2
= (15 + 12 - 11)/2
= 16/2
= 8</p>
<p>what was the democratic senators one?</p>
<p>Does anyone remember the question with the square with a side of 6??!</p>
<p>
</p>
<p>yes… what about it?</p>
<p>can you tell me what the question was?
i forget what it was and i wanna know if i got it right</p>
<p>For some reason I do not remember what the hose question was. Can anyone remind me?</p>
<p>hose fills bucket in 4 min, fills another in 30. how much bigger is the bucket. answer is 15/2 or 30/4 or 7.5</p>
