<p>There was one on the math with two circles and a pulley can you explain that?</p>
<p>You know the 22pi/3 since thats from the “2/3rds of the bigger pulley and 1/3rd of the smaller pulley” and you know their radii. The rest of it you can make a 30 60 90 triangle. The hypotenuse is the 8, the smaller leg is 4 (thats in the bigger pulley, and don’t think of it as going straight up, think of it as going from the center of the pulley to the point where the belt hits the pulley", and that leaves the middle leg exposed, making it 4root3 by the 30 60 90 triangle rule. Double that, cuz its the top and the bottom, you get 8root3</p>
<p>The easiest ACT I’ve taken so far, so I hope it’ll be good. Okay so for the pulley problem, you have to first find the circumferences of the two circles. The band wraps around 2/3 of the big circle and it wraps around 1 third of the small circle, so you can calculate accordingly to produce a value of 22pi/3. The straight lines are the issue in this case. First, you should know that the bands become straight at points of tangency. So draw in radii in the circles to try to create a shape that will isolate the straight lines. Next, divide the big shape, which kinda looks like two trapezoids meshed together into two with a horizontal line (which is 8, according to the diagram). Thus, you are left with two trapezoids. Knowing that radii intersect tangents at 90 degree angles, divide just one of the trapezoids into one right triangle on the outside and one scalene triangle on the inside. Use law of cosines to find out the missing side of the scalene triangle, which is the hypotenuse of the right triangle. Use pythagorean theorem to find the straight line distance. Then multiply that by two because you have two straight lines. The answer becomes 22pi/3 + 8 root 3. This explanation probably makes no sense whatsoever. I heard some people used a rectangle method.</p>
<p>Was there also 8 root 2 as an answer? I guessed 8 root something not sure if I guessed correctly.</p>
<p>^ I got 22/7 plus 8 root 3.</p>
<p>Can anyone tell me how they felt the science was like? This is the first legitimate ACT I’ve ever taken, and I didn’t study or look through any practice problems at all since I already did well on the SAT. I feel like the math and writing was much easier than on the SAT because it was more straightforward (finished with more than ten minutes to spare on each section). The science threw me though, since I wasn’t prepared for it at all. How many can you miss to still do well?</p>
<p>I thought the science was very easy. I finished with 6 minutes left and had time to look over questions I was unsure of. Although, on the science section 2nd to last passage, there was a question that asked what study 1 tested and if it gave three types which were Adults with (something), Adults with no (something) , and juveniles. I can’t recall exactly the answer choices but does anyone remember which of those 3 types were included in the correct answer?</p>
<p>There were no juveniles (passage said they took 200 adults) , which eliminated all but one choice</p>
<p>I’m not too good in science, but I remember referring back to the passage and reading something about juveniles, so I put that answer choice only. In fact, “juveniles were collected” was directly stated in the passage, but I’m not sure about any of the adult choices.</p>
<p>@warren1717: That’s what confused me. It mentioned 200 adults, but I distinctly remember reading “juveniles were collected.”</p>
<p>The question stated that 200 adults that breed were tested but that alone wasn’t an answer choice. The adults that don’t breed was never mentioned in the question. Was it supposed to be implied that the other type of adults were included as well?</p>
<p>I think in reference to study 1 or trial 1, whichever it was, 200 adult fish were collected. I don’t recall anything about juveniles being taken, so I inferred they took both breeding and non breeding. Just my opinion though</p>
<p>I believe it was juveniles only. In the description that the adults were tagged, and the offspring were collected.
Also the first passage with the reading, was the line and shadow both inspire something. i think that was the question.
And the first passage for science, the last question it was about 2 cm then 7 or something anyone know that one?</p>
<p>I put all three, because the graph’s x-axis had juvenilles, adults, and a sub section for “breeding adults”. I don’t know if the graph was the right place to look to answer that question. I usually dont read the text in science passage.</p>
<p>I think you’re right Nivers. The graph had all three groups. Besides the study is based off of the offspring, not the parents, anyways.</p>
<p>Also, Student, I think the answer to that reading question was that the shadow meant that something ominous was coming and that the line was some kind of haven for the orange to grow.</p>
<p>^Yeah, that’s what I put also.</p>
<p>I put all three as well. The question was based off study 1 and study 1 included the figure that had all 3 types.</p>
<p>The answer was juveniles were collected. It clearly stated that juveniles were collected. The graph showed the percentage of fish of each percentage of genotype through adulthood. That’s why it showed only juveniles up until 2007. The reason the graphs vary is because it was implied that some of the in tagged juveniles died before reaching adulthood.</p>
<p>Essentially, the answer is juveniles only because the graph showed only juveniles collected at the beginning of the study and because the passage stated that only juveniles were collected.</p>
<p>Hope this clears things up.</p>
<p>The answer was juveniles only. Initially, a group of adults is tagged. Then the adults produce offspring (juveniles) who are examined through adulthood.</p>
<p>I actually read the passage and it specically used the word “collected” to describe the collecting of the offspring for observation. The adults were obtained and tagged, but the passage refrained from saying they were collected. For this reason, I would say A.) Juveniles Only was the answer.</p>
<p>I forgot what question this was from, but was one answer the following?</p>
<p>Electron , Proton</p>
<p>neg was electron and positive was proton.
also the question regarding the seed problem was above 7</p>
