hindi ba 2 pesos din ang sagot?

 

you give half (tag-piso kayo)

then you get it back.

 

?? baka di ko na-gets.

[ibirp]

tama, 2 Peso din. kasi, for 1 flr, kung may 2 peso ka, bigay mo sa kanya yung half (1 peso) tapos, balik nya rin sukli sa 'yo na 1 peso, so 2 peso uli money mo.

 

this case, kahit ilang milyong floors yun, pa ulit-ulit lng ang sequence.

'pag may elevator na ganito, pwedeing pagkakitaan to!

 

pasok ka dun with 1 peso. for 1st floor, bigay mo 50 cents, tapos balik nya 1 peso, so 1.50 peso na money mo. uli-ulitin mo lng ang sequence, magiging milyonaryo ka.. hehehe....

thanks for the answer for question #1... eh yung formula pano derive?

[akira]

hayyy;

 

 

maski naman cno yan problem eh math......

[www]

i hate math! i never liked it! and definitely wasn't good at it either!!! i'm soooo glad, school's over a long time ago... all i needed was a calculator and i'm set for life

[twisted minds]

thanks for the answer for question #1... eh yung formula pano derive?

 

algebraically it reminds me of a similar to the proof that is

 

1 = 2

there's no 'formula' in the real sense you just work backwards..

 

say i'm at the last stop, i have x pesos.

 

I give him half, leaving me with x/2.

 

He gives me 1 peso back, so I have:

x/2 + 1 = the desired 2 pesos.

 

solving, we get x = 2.

 

From the answer we see it doesn't matter how many floors there are.

 

Now, if the answer was not 2 ibang usapan yun, because then you would have to go through the process above 20 times before you worked out the answer.

Let X = money mo sa top floor (in this case 20th)

Let N = number of floors below the top floor (in this case if n=1, youre at the 19th floor)

Total amount of cash at floor N below the top = (2^N)*X + 2 - 2^(N+1) --> try it. Eto yung pera mo bago mo bayaran yung guard.

 

So bale kung 2pesos lang matira sa yo at the top, X = 2. Plugging that into our equation:

(2^N)*2 + 2 - 2^(N+1) = Cash

|

this will become (2^(N+1))

 

2^(N+1) + 2 - 2 ^(N+1) = Cash //yung dalawang 2^(n+1) will cancel out

2 = Cash

thus showing that if the money left at the top floor = 2 pesos, the money at any floor below the top floor is equal to 2 pesos.

A quite simple question:

 

The area of a rectangle is the product of its length and width, or;

 

A=LW

 

How is it derived?

I'm not sure if there is a derivation of this. My impression is that this formula is part of the fundamental definition of area itself, and all other formulas for areas are derived from this.

common knowledge..its the law

[poppinfresh2k5]

i wish they could make a common sense theorem in geometry... anyhoo... basically derived from a square. a square is a rectangle with all sides equal and at right angles. the area for a square is basically side squared. so start with a square with an area of one. now figure in a rectangle and any given length or width. start with an example of rectangle with one side hvaing the measure of 1 for width and a measure of 4 for length. so what we do is place those 4 squares in a line... so thats a rectangle with a width of 1 and a length of 4. simply add up the areas of those four squares with an area of 1 and you get 4. so how do you derive 4 from the measure of side with a measure of 1 and a measure of 4? well logice precludes that we can follow the basic measure used by deriving the area of the square which is side squared... or a change in linguistics... side times side. so 1w times 4l equals the area of the 4 squares forming the rectangle.

 

but honestly... this really does not need any explanation at all. seriously.

Any real number divided by 0 is undefined

 

 

kakatuwa..

 

wala ka namang papartihin sa wala, so simpleng sagot - none, zilch, zero

[marco_antonio]

sa 0/0 yun. In real numbers/0, undefined
