I mean lets assume I have 5 zoos - 4 zoos, how many zoos are left, 1 zoo .. but once the question talks about bits in computing world, then for example 20 bits - 4bits, how many bits left? I sometime get stuck three hours on that simply question .... and I think that's because I don't know what subtract means, as a result I must first understand what's the term subtract mean in order to get used by it and...

So may anyone please explain to me what's subtract means?]]>

Explanation:

What I did is I got the highest number that both numbers divide to. I got six then, I divided 6 by 3 and 18 and I got 2x=3

If I am wrong explain please to me

Thanks]]>

and using "all the tricks of the trade", create equations showing

as result 1000 + post#.

As example, this post# is 1, so the 2 equations must equal 1001.

0 + 1 + 2*(3 + 4*5 + 6*78 + 9) = 1001

987 + 6 - 5 + 4 - 3 + 2 + 10 = 1001

Btw, 0! = 1 is allowed.

I'll do the next one (further example)...then whoever is interested

can do 1003...and so on...

RULE: ALL posts require this to be done ...... OK DAN?!]]>

Question: The electrical resistance of 1 metre of a certain wire is directly proportional the square of the diameter of the wire. Wire with a diameter of 2mm has a resistance of 1.20 Ohms.

a) Write a formula for the electrical resistance of the 1m wire as a function of its diameter.

b) Determine the electrical resistance of a wire with a diameter of 5mm.]]>

Consider the following calculation. State which laws of arithmetic are used and indicate at what stage they are used.

4 x 37+ (56 + 4 x 13) = 4 x 37 + (4 x 13 + 56) ( I think this line shows Commutative law)

= (4 x 37 + 4 x 13) + 56 ( I think this line shows Associative law)...

Knowing: \(\displaystyle |a+b| \leq |a|+|b|\)

I have to demonstrate that: \(\displaystyle |a-b| \leq |a-c|+|c-b|\)

I appreciate if someone can help me how to start.

I dont know if I can do it just with \(\displaystyle | x |\) properties or if I have to use the following: if \(\displaystyle a \leq b+\epsilon\), \(\displaystyle \epsilon \gt 0\) then \(\displaystyle a \leq b\)

Thanks in advance]]>

lets assume I do 4/2 then it's equal 2 ..it's fine for me! but lets assume I do 3/4 so the answer is 3/4 but it's not making sense, because to find the answer of "3/4" is the same to say how many "4" in "3" ?.... so is the answer for that question 3/4? if so .. it's like something not making sense]]>

The Problem is as follows ;

Determine whether the sequence converges or diverges. If it Converges, give the limit.

60, -10, 5/3, -5/18, ...

I am still unsure how to start and how to find the limit (if it does converge)]]>

Eq. 1 : (bx / 40212.4) + y ( (4/3) - (b/22619.4) ) + 2z = (50/3)

Eq. 2 : (4/3)x + y ( (32/3) - (b/22619.4) ) + 4z = (6395/24)

Eq. 3 : 2x + 8y + z = 2125/8

How do u solve this system of equations in terms of b?

lets assume I have variable x which it gives me volume 5a

then what's the volume of 3x? my question here is:

I know if I multiple x by 3 then I will get 3*5a=15a but my question who said that the relation between x and 5a is linear also who said that if x=5a then must 3x give me 15a .. is that math assumptions? any help]]>
