<p>Yeah that math one with the corals totally stumped me. I skipped the first one and <em>attempted</em> the other two</p>
<p>^basically the same for me. I think I MIGHT have gotten parts ii and iii on letter c of that question, but part i I “attempted” as well by writing random numbers from the table adn doing fake multiplication lol.</p>
<p>The 1998 exam on the college board website was ridiculously easy, that one today, i thought was really difficult. The MC and FRQ… :(</p>
<p>Math FRQ
Corals Stuff (NOTE: ALL ANSWERS ARE PER YEAR)
- Volume = 7.5<em>10^8m^3 (.003m)</em>(2.5<em>10^11m^2)
- Mass = (7.5</em>10^8m^3)<em>(2</em>10^3kg/m^3) = 15<em>10^11 kg
- 20% of = (15</em>10^11 kg)<em>(.2) = 3</em>10^11 kg</p>
<p>Those are the right answers. I have all the other math ones memorized too if you want them.</p>
<p>^I don’t agree with your number three…but I’m gonna stay on the safe side and tell you why in two days :P</p>
<p>w/e lets compare answers, its not like we’re not getting the frqs back in 3 days nyways</p>
<p>-Freshwater problem - answer i put was “the creation/expansion of cities in area with low rainfall”. Pretty certain thats right.</p>
<p>-The EM spectrum on the Earth is mostly what?
It was asking what part of the spectrum living things use most. I put visible. </p>
<p>-What two factors determine how fast a landfill decomposes (something like that)? Aeration and moisture? <----Thats what i put</p>
<p>For these next two I was 50-50 between two choices:
-Something about what ESA entails/is. “Only applicable to federal lands”, or “based on biological data”. This one i picked the bilogical data answer. </p>
<p>-Integrated Pest Management: using “a variety of techniques” or “eliminating synthetic and inorganic pesticides.” Wikipedia gives both answers -_-
I put varriety of techniques…but its a guess</p>
<h1>3 asked by what quantity would the yearly mass decrease by 20XX. It didnt ask for what the mass would be that year.</h1>
<p>pretty sure the EM question was asking about the what form the sun’s rays took, which would be mostly ultraviolet.</p>
<p>Ehh, I’d disagree. Isn’t most of the radiation visible light? The UV rays are absorbed by the stratospheric ozone layer.</p>
<p>Also, in b4 getting screwed over by College Board for talking about the MC and FRQs?</p>
<p>"-Freshwater problem - answer i put was “the creation/expansion of cities in area with low rainfall”. Pretty certain thats right.</p>

<p>after talking it over with my friends, i think these are the two that we disagreed on most…and others seem to disagree on the EM spectrum one. opinions?</p>
<p>I’m not sure anymore. You have me questioning myself. Do you remember the exact wording of the EM one?</p>
<p>@withparanoia
Yea I got the same answers as you</p>
<p>and idg why we cant discuss for 2 days… its not like people in hawaii stillll havent taken the test!</p>
<p>it’s comforting to know that everyone else had so much trouble…also did anyone know what on earth those diseases were in the beginning of the mc? i knew dysentery, and that was it…</p>
<p>The MC was harder than I thought it would be. FR was easy as usual except for that math problem, I skipped it, but came back to it with only 10 minutes. Yeah I didn’t get the diseases either.</p>
<p>minamito was the mercury poisoning. what was dysentry…along with the rest? and which one of the diseases wasn’t used?</p>
<p>Redsox, you got the math for #3 wrong. GG.</p>
<p>I got the exact same math answers as redsoxrbest.</p>
<p>he/she got #3 right. it asked for the difference, which is equal to 20% of the total quantity, which he/she correctly calculated</p>
<p>damn it never mind sorry AHHAHAHA</p>
<p>Thanks APchemistry. I think they just threw #3 in there to be confusing because it was worded really oddly.</p>
<p>@dfire28: Aswan Dam -> schistosomiasis
Fatty Build up ->atherosclerosis
Sewage into rivers -> Dysentary</p>
<p>Mesothelioma was unused (formaldehyde causes it, just fyi)</p>
