<p>This is signatureCC’s explanation (pg 2):
For what values does p* = (100p)<em>,
where a</em> = sum of prime factors of a
For any prime number, the only divisor is itself and one.
This implies that the sum of prime factors of a prime p is simply p.
100p = 2^2<em>5^2</em>p
Therefore, (100p)* is the sum of all prime factors of 100p, which are: 2, 5, p.
Thus, RHS(Right-hand-side) equals 2 + 5 + p.
LHS(Left-hand-side) equals p, as established above
p = 2 + 5 + p
0 = 7,
which is obviously always false, thus for no prime value, p does this equation have a solution.</p>

<p>I think it makes sense that its zero.</p>

<p>Crap /:frowning: that question was so bad</p>

543

<p>The student one was definitely 4, not 2.</p>

<p>Chem: 14 - 4 = 10
Physics: 12 - 4 = 8
Both: 4
Neither: 10</p>

<p>All of them added together would be 32, which is the total number of students.</p>

544

<p>tell me about it :/</p>

<p>For the car passage in writing, did everyone say “delete the sentence” for the question about the differences between used cars and new ones? I changed it to “buying new cars and buying old ones,” but it was the only writing question i was unsure of.</p>

545

<p>Any other thoughts about 0/3+ before I sleep restfully ?</p>

546

<p>can you refresh me on that question again? What was it saying and asking?</p>

547

<p>@theuntruth I picked the same that the sentence should be buying new cars and buying old ones. Do you remember any other questions? Such as the other improving paragraph questions</p>

548

<p>for the used car question on the passage, im pretty sure it was “buying a used car and buying a new car”</p>

549

<p>Did anyone answer something about “misrepresenting the 1970s” for one of the questions about pertaining to the “conflicting viewpoints” passages about employment?</p>

550

<p>I said to delete it</p>

551

<p>I dont think I said anything about misrepresenting the 70s for the employment passage. I might just not remember though lol. It was about the work hours and how they’ve increased, correct?</p>

552

<p>It was definitely to delete the sentence. It just sounded too out of place.</p>

553

<p>theuntruth: the question was, specifically, asking for what author 2 would say about author 1’s claim that presuming to know anything about the past would be more or less to consult myths etc. or something… I said that author 2 was accusing 1 of misconstruing understanding of the 1970s by claiming that no definitive evidence for 2’s argument existed from that time period. or something like that lol.</p>

554

<p>What were the answer to the circle question where the little circle was how many times smaller than the bigger one?</p>

<p>And what was the answer to the question that had a picture of a line and it asked how many times it hit the X axis?</p>

<p>Also, what was the answer to the picture one that had a spiral and asked for the answer in pie?(LOL)</p>

<p>AND was one of the answers 30%? The choices were like 30%-40%-50%-60% and 250%(HAHA)</p>

555

<p>5<em>= 5
500</em>= 5+5+5+2+2
It doesnt work because you have to add the other prime numbers that make up the product of 100</p>

556

<p>Didnt you have to find the length of the line, not the area?</p>

557

<p>Yeah but they make him about to be so harsh throughout the passage, I was stuck between indifferent teacher and sharp critic</p>

558

<p>@AimingForA1200 were you talking about my questions?</p>

<hr>

<p>What were the answer to the circle question where the little circle was how many times smaller than the bigger one?</p>

<p>And what was the answer to the question that had a picture of a line and it asked how many times it hit the X axis?</p>

<p>Also, what was the answer to the picture one that had a spiral and asked for the answer in pie?(LOL)</p>

<p>AND was one of the answers 30%? The choices were like 30%-40%-50%-60% and 250%(HAHA)</p>

<hr>

559

<p>guys… I was just thinking about the p* question, and I’m pretty sure (unfortunately) now that the answer was more than 3.</p>

<p>the question defined 45* as 5+3 = 8, which means that you only consider each factor once. Therefore, 10 (2+5), 100 (2+5), 1000 (2+5), etc. should all work</p>

560

<p>unless… did the problem ask “for what prime number(s) p”?</p>
