Why am I slow at logic and math questions?
Read the question. Read it again. Think about previous, similar questions. Underline the bits you think are important. Read the question again, to make sure you understand what they want to know, and what you have to start off with.Almost every text book has examples. Do Not Read them! WORK through them, step by step, and if you don't understand a step, ASK. Maths is really simple, unlike every other subject there is a right answer, so if you can get each step correct you should get the larger problem correct! Now, once you have worked through the problem, following each step, try again, checking the steps against the book after each one. THEN do it again, only checking if you get stuck, then finally do it one last time, without the book. If you think that this is much too laborious, don't worry, because, as time passes, it will get easier. You will recognise problems as being similar to ones you met earlier, and, eventually, your confidence will increase and you will be able to work on more complicated mathematical problems without having to go through all the steps. Very few people are born mathematicians, most people have to put in some work, and the earlier you start the easier it is!Just take it one step at a time!
Java help ... I'm stuck?
Write a method named sumCalc that takes in two double parameters and returns the sum of those two numbers. For example, if you had the following call to your sumCalc method: public class Meth2 { public static void main(String [] args) { double number = sumCalc(2.5, 3.6); System.out.println("Returned value: " + number); } // Your sumCalc method goes here } then it would print out the following to the console: Returned value: 6.1
Can someone help me with this physics problem...i'm stuck..plz help.thanks?
These are plug and chug questions. You clearly need to study your assignment to understand the relationship between kinetic energy and momentum. 1) KE = Pc = 1000 GeV; so that P = KE/c = 1000 GeV/c ANS b) 2) We move one path 1/2 wavelength further and one wave reaches the screen (destination) with a crest then the other reaches that same screen 1/2 wavelength out of phase with a trough. They cancel and, so, that's destructive interference. Move 1 wavelength and crests from each path reach the same screen in phase for constructive interference. Thus, by extending the path in increments of 1/2, 3/2, 5/2, etc. ((2n + 1)/2)L we'll get destructive interference. By extending the path in increments of 1, 2, 3, etc. (nL) we'll get constructive interference. As destructive interference happens when [(2n + 1)/2]L = 2n + 1, the only answer that matches is d) 7 m. This occurs for n = 3 when the length of one path is extended 7/2 wavelengths.
HELP! Chem Test Tommorow - I'm stuck on two questions?
For your first question, you can use the periodic table as a reference. As you move from left to right, the atomic radii increases. I don't quite have an answer for #2, sorry.
9th Grade SHSAT Questions?
1) For me, I would say the verbal part was slightly more advanced and the logic was a bit trickier but they mostly remained the same. The math in the eighth grade included mostly algebra and maybe a few geometry problems, but for the ninth grade, there were tons of geometry and the algebra was way more advanced. I wouldn't say it was too hard, because from what I heard before I took the test, there was supposed to be Trig and way harder logic questions, but there weren't any Trig on the actual test. 2) LOL. SAT classes might be a bit too much, the stuff on the SAT might be too advanced for this, since SAT2 include some pre-calculus problems and bunch of trig and algebra 2. But I guess if you want to start preparing earlier, go ahead and take those classes. As for the SHSAT classes, they might help you a bit, but there are very little prep classes for 9th grade SHSATs. 3) Mhm. I guess like a 7-8. 4) The cutoffs might be around 520+ the least, but they usually depends on the scores that every has. If most people scored higher scores, the cutoff would be higher as well. 5) You'll be transferred in the 10th grade. The test is usually one day or one week either before, or after the 8th grade SHSAT. Just keep in mind that the test might turn out not be too hard for you, but they have WAY less seats for 10th graders. Some people say S.I.T offers 30 seats for 10th graders each year, some say they offer 16, but I don't think anyone is entirely sure, since they're never announced. Btw, If you're taking it next year, make sure you're fine before opening the test booklet, you can always tell them if you're not feeling well before starting the test. Because once you opened that test booklet, there's no turning back. ;D Excuse me if I have any typos and that stuff 'cause I'm rushing to leave the house. I wish you luck for next year. Kbai. c8

BIOLOGY HELP!!!!!!!!!!!?
This actually isn't as hard as you might think. Let's work backwards. Right off the bat, we can say that tube 1 contains the RNA. We know this because RNA consists of many nucleotides bound by a phosphate backbone. Lysine, insulin, and RNA would all test positive for nitrogen. We already know which tube has the RNA, so we're left with lysine and insulin. Lysine has only one carboxyl group (if you didn't already know this, wikipedia shows the structure). Therefore, we can come to the logical conclusion that tube 2 contains the insulin. This makes sense because complex proteins (like insulin) are made up of many amino acids, and every single amino acid contains a carboxyl group. Now all we have left is lysine and lactose. Which one of these can be hydrolyzed? If you have limited experience with organic chemistry, this is a pretty challenging question. But if you were to look up hydrolysis on wikipedia, you would see it loosely described as a chemical reaction in which a molecule is "broken," splitting water into H+ and -OH in the process. For this to happen, you would typically need to have a very electrophilic position within the molecule in question, since a lone pair on the water's oxygen needs to attack something. Look now at the structure of lactose. It doesn't appear to have such a position. It has many OH groups, but these are not electrophilic. In water, they'll just flip flop between HOH+ and OH. But lysine, being an amino acid, has a carbonyl carbon which is very electrophilic. Water can attack this to break lysine into an amine and carbonic acid. Knowing all this, we can say that tube 3 is lactose. Summary: Tube 1 - RNA Tube 2 - insulin Tube 3 - lactose Tube 4 - lysine
