From the trivia question Math SATs #295: I'm planting 8 trees in a circle so that they are all equally spaced. If the radius of this circle is 5 m, how far would each tree be from the tree next to it (in a direct line)?
There are two ways to do this.
The simple way is to realize that the circumference of a radius 5 circle is about 31. Since we have 8 trees, we have 7 spaces between them, so dividing the whole circumference into spaces between each tree gives a bit more than 4, which means the direct linear distance should be around 4.
The more formal way is to use cosine law- draw a triangle between two trees and the centre. The angle between the two radius-sides of length 5 will be 360/7, or about 51 degrees, so you have two sideds and the angle between them, just plug it into the cosine law and you get about 4.
From the article Arkansas Tech's Tuition and Fees
Thank you for highlighting this to us. The lesson has been updated with the appropriate values.
What makes Arkansas Tech exceptional value for international students is that fact that these totals include your living expenses, insurance, and books - it is not just the total tuition for your programs which is the number that you will see quoted most often during your research. Most students will also just take the standard 8 month academic year - which results in a total graduate cost of $13,338. I think that you will find this to be quite a bit lower than other universities in the USA.
Please let us know if you have any more questions! The staff from Arkansas Tech International Office is on LearnHub and would be eager to speak with you if you send them a message or post a query here.
There are no special SAT courses other than preparatory courses offered by institutes, but they are not mandatory. It's recommended that you study using preparation books such as the Official Guide, Princeton, or Kaplan. If you need extra practice or help a prep course may be beneficial.
There is a test center in Chisinau where you can write the SAT. You should check the CollegeBoard site for information and registration. Good luck.
From the article 8 Engineering Streams For Study US, Canada & UK Aspirants
Some current research areas in electrical engineering include micro and nano electronics (really small electric circuits and devices), the whole big semiconductors area, improving satellite telecommunications, and more. There's no lack of research areas, but most are applications of electrical engineering to either smaller frameworks or different fields, since there's only so much you can do with a regular circuit.
From the question jobs for Finance Graduate in New York
This depends a lot on his visa situation. It'll be a good idea to contact an immigration professional who can indicate whether your son's student visa allows him to work in the US and under what conditions (unless of course he has American citizenship).
Now other than that, his GPA is fairly high, but there are a lot of other factors involved, such as which school he's attending, class ranking, past experience, and personal skills and abilities. I would not say it's impossible to find jobs at the moment, but it is very tough, the financial crisis hit the New York finance industry pretty hard. However, it's important to remember to stay flexible- jobs that aren't directly related to finance can still offer a good experience that will give your son potential benefits in the future.

Check the college's website, it'll usually have a page about financial aid and scholarships for applicants. Also, when you apply you may receive some info about potential scholarships from the college. If you're looking for scholarships that aren't specific for that college, this lesson can help.

Hello Saqib. You can look for some great schools and programs in the UK and globally using our School Finder. There are lots of lessons and resources for you in our Study in the UK Community, reading through them will help you figure out all the various steps in the application process.
From the question SATs difference between Canada and the US?
I suggest study as much as you can. For students coming from India like yourself, the math sections tend to be a bit easier but the English ones are typically harder, so you may want to focus a bit more on those. You should prepare until the scores on practice tests are about the same as the scores you wish to achieve on the actual SAT, and it really depends on the individual person, so I can't really say a week or 6 months. I think usually a month or two of casual studying followed by a few days of intense review are usually quite enough for most people/
From the question how do i get in to MIT USA
Above 740 would be pretty good. I mean, if you look at this lesson the range of scores isn't terribly high, and you still stand a chance of getting into MIT with a 660 in verbal and 720 in math, and potentially even less. But again, if you're competing for the more prestigious programs and scholarships , the better your score is, the better your chance are.
From the article Albert Camus: The Myth of Sisyphus
I don't think the two are similar. Milgram's experiment was looking at obedience and concluded that people tend to follow authority's orders blindly. Camus talks about the meaninglessness of life and how people deal with it.

From the question Can you give me tips for the test day?
A few tips:
Relax. That's most important thing. Sleep well the night before (don't cram more studying last minute), eat breakfast, etc. You'll need the energy.
Make sure to leave questions you don't know blank and come back to them if you have time afterwards. It always surprises me how many people don't do this, but it's a very basic important thing. Also, don't rush through the easy questions (you can easily make silly mistakes) and don't spend too much time on the tough questions (if you know you can't solve it, leave it blank and move on).
Don't try and guess which section is the one that doesn't count. Just answer everything as best you can.
And good luck!
From the question What is the required SAT score for Ivy League admission?
Here you go. It's a lesson with average scores for top schools. If you're above 700 in each section you're doing fairly well.
From the question how do i get in to MIT USA
A 2300 will give you much better chances. If you have close to 800 in the math section and a really high score in the reading section as well, the writing section tends to count a bit less, but as an international student trying to get into MIT you're competing with the smartest people your age from all over the world, so you will need a really high SAT score to get in.
From the question is the hundrendth digit of decimal d greater than 5?
This is easy if you use the "moving the dot" technique.
Statement A says the tenth digit of 10d is 7. So say 10d = 0.7. Divide by 10 means you need to move the dot one step to the left, so d = .07, in which case the hundredth digit is 7, greater than 5. Similarly, statement B says d/10 = 0.007, and now we multiply by 10 and move the dot a step to the right, and again d=0.07. So either statement is sufficient.
You may be confused by the direction of where to dot moves, or by the wording- the "tenth" digit doesn't mean the "tens" digit (for example, in 20.5, the tenth digit is 5, not 2). That's an important wording issue. So in 70.1203, the thousandth digit is 0, the hundredth is 2, tenth is 1. Hope this helps.
