<p>for marie curie, wasn’t the error “most biologists”</p>

<p>basically it was saying her theories differ in terms of…from most biologists</p>

<p>it should be changed from “most biologists” to “the theories of most biolgists”</p>

<p>correct me if i’m wrong</p>

<p>I had lots of E’s in sentence err id’s:</p>

<p>“…adversely affected…”</p>

<p>“…turned to greek mythology for subject matter…”</p>

<p>“musuem is submitting proposals to several foundations in the hope to gain…”</p>

<p>and for the pollutants, cities, smog one, is “concentrated” wrong or no error?</p>

<p>rishtanna, you’re right.</p>

<p>always,
“museum is submitting…in the hope of gaining”
for the pollutants one, i put no error</p>

<p>I think we should compile all the answers we got for math/CR…and put them in one big post. Makes it easier to search through.</p>

<p>BREAKING NEWS: The last grid-in was in fact 19.6</p>

<p>here’s the true approach: Find the area of the square that the triangle is halving by multiplying the area of that triangle by 2:</p>

<p>7 * 2= 14</p>

<p>To get the area of the elongated rectangle, multiply by 1.4 (since it stretches out by a length of .4 from the 14 area rectangle)</p>

<p>14 * 1.4 = 19.6</p>

<p>its like a square, being a part of a rectangle that is stretched out 3 times as far the length of one side of the square. You’d multiply the area of that square by 3 and get your answer.</p>

<p>youre still wrong</p>

<p>got lotsa C’s and D’s in a row too… like 2 or 3 each time. kinda weird too.</p>

<p>that is assuming the propotion of the sides is 2:5 which woudl mean that the qutesion SHOULD have asked 2/7 but the quetsion asked 2/5 s o you woudl put a proportion 2:3 so instead you multiply 1.6666 to 14. </p>

<p>70/3 is the answer, so its not any breaking news. sorry.</p>

<p>and btw it said 2/5 of the length on the right, not the entire lower line segment I’m pretty sure</p>

<p>To solve the firetruck question:</p>

<p>4!/ (2! x 2!) = 6</p>

<p>4 Blocks on both sides and 2 on each side. </p>

<p>The last grid-in: separate 5x in to 2 and 3 (bec of ratio 2/5) and double the triangle of area 7 to get 14. You now have 14 with 3x. Use ratios to find the area w/ 2x = 9.33
Add together = 14 + 9.33 = 23.33 = 70/3</p>

<p>Cecil is NOT an experimental.</p>

<p>

</p>

<p>If you want to think of it that way, the ratio of the length of the long side of the rectangle to the length of the triangle side is 5/3 (not 1.4). 14*5/3=70/3.</p>

<p>The ratio was the length on the left is 2/5 the length on the right</p>

<p>Did anyone have a question where there was an election between two candidates and the one dude won by a ratio of 3:2 out of (x) amount of votes total.</p>

<p>What was the total amount of votes for the loser?</p>

<p>It was just 3x+2x = (the total - no, I don’t remember the EXACT #)
Then multiply x by 2</p>

<p>:D</p>

<p>Vagrant >> i read the question wrong in the beginning like you but i caught my mistake. it is of the WHOLE bottom length not the just to the right. i almost screwed it over but it is 70/3.</p>

<p>I got 4 “No Errors” on writing identifying errors. That is a lot more than usual. But i couldn’t find any errors. Did anybody find errors in the pollutants, mythology, and two others…?</p>

<p>no, it’s the length on the left is 2/5 the total side length</p>

<p>nope…it was 2/5 of the total.</p>

<p>If It was line ABC…AB was 2/5 of AC</p>

<p>programmer- it was 46000 i think</p>

<p>

</p>

<p>Right. So the ratio of AC to BC is 5/3.</p>
