cant understand maths. If anyone willing to help, give me Q.

[Jimmylicious]

Pyramid base border length is 1dm (1dm-10cm) and the corner between side edge and the base  (<ADS) =60 degrees (i dont know, google translator told me so lol)
1) count the piramids base longest diagonal lenght (AD=BE=FC)

in a 6 corner pyramid R = a (radius of the outer circle)
therefore  2R = 2a = 20

Pyramid with a six-sided base is consisted out of six equilateral triangles (the ones with all three sides equal). Since you're given the total length of the outer border, the length of one side of one triangle is one sixth of the total length: 10/6 or 5/3 for short. Obviously, the lengths of the other two sides of one triangle will be the same. The longest diagonal will be between two points on the base which are opposite from each other (in this case AD or BE or CF). Then the length is just double the size of the length of the side of one of the triangles in the base, so (5 * 2) / 3 or 10/3.

a = 10/6

I think he meant by 'border length' the perimeter of the base.

Ok any Geography geeks here?

What do you need? Physical geography, cartography, geopolitics, ...?

I couldn't have done it myself but after reading your explanation man it's easy as fuck

A problem is that the system overall trains people these days to stick exclusively to scientific methods instead of using common sense every now and then.

An example was the last remedial math test (basic math, as we call it) we had last academic year (we have two math subjects; regular math with advanced algebra, trigonometry, and statistics, and basic math since my school's population were getting more dull in math)... the majority of my classmates failed to answer the following problem.

"Here is a number line from 0 to 1. First, plot 1/2 on the number line. Next, choose a fraction smaller than 1/2 and plot that on the number line as well. Afterwards, explain why you placed the two fractions in their respective locations."

??????

1/2 cuts the segment in two and 1/4 cuts the first half in two

did i win???

[ElMartu]

I'd place the fractions where I placed them because that's where they actually go: 1/2 goes in the exact middle of the line and and the other fraction can go whenever I want as long as it's smaller than 1/2

Correct. This was my answer as well. My classmates failed because they were too busy ignoring common sense.

The problem would be explaining why the fraction of the said value goes into the appropriate place in the number line. An example would be a classmate of mine who chose 1/6 after plotting 1/2, only he did not know how to explain it.

Ok this is something I have learnt from college.

We have a segment AB and we want to cut it in 3 equal pieces. We draw for example any line starting from A other than the perpendicular to (AB) then we take the compass (or ruler) and start making even pieces as shown:



Then we link the end of our created equal parts to the end B of our segment and we draw parallel lines to that line in each end. Well maybe my explanation sucks but you get the point when you see this:

Hi Good Men, Need to write an application for college admission, help me please? If you want I can reward you with In Game money for it.  :devroll:

Well the fact you're asking an online gaming forum to write it for you doesn't say good things about your academic achievements.
