:lol: how do you find the volume of a cilinder
Ok, I got most of that.
But, I'm still wondering why is 0.75 irrelevant? And how do you [^] a number on this page?
I need to understand why for example
[A radioactive kalashnikov gets less radioactive every year. After 60 years only 25% of the radio-activeness remains. What is the yearly reducing of radio-activeness in percent?]
I'm wondering. Since(Based on my assumption) 0.75^(1/60) should be in english: 75% of of the radioactiveness in one year. Since 75% was removed during 60 years shouldn't 0.75^(1/60) be the answer?[1 - 0.25^(1/60) = 0.75^(1/60)? ] And also. Why should it be ^(1/60) and not the percentage divided by 60?What does ^(1/60) actually mean? What happens when it calculates? I'm aware it multiples itself the times stated. For example: 3^3 = 27 ; 3^3(1/3) = 9 I must understand these things. It's good to know how to solve something, but if you don't know the meaning of it you can't solve another thing. I'm going to guess only Melody could explain this, but others are also welcome. IF you actually know the significance. Do not guess while trying to explain as it would only confuse me. And by the way, I may have confused you a little bit with what I'm trying to say. Good luck and thanks.
Little logic's puzzle for whoever is interested,
You are on a quest from Proqzanthar to Krighontyr but find a T-crossing and don't know which way to go.
At the T-crossing there are two twin brothers of which one is always true and the other is always false, but you don't know which one is which.
You can ask only 1 question to either of the two brothers.
Which question do you need to ask to know whether to go left or right?
I am not sure that I understand the question.
If I can ask 1 brother 1 question and then ask the other brother a different question then I know how to do it.
Is this what you meant?
Here are the next ones (choose the one that is best suited to your ability level)
You have to use some or all of the numbers to make the magic number. You are not allowed to use any of the numbers twice. (Unless one was written twice in the first place)
You can use brackets, +, -, x, or divide and that is it.
2,3,6,6,8,50 and the magic number is 972
EASIER ONE (not done yet)
3,5,2,4 and the magic number is 40
1 TB = 1048576 MB @ 1.5 MB/s = 1048576/1.5 = 699050.666667 seconds = 8.1 days
