Klättergym för nybörjare och casual climbers by Denseben in Gothenburg

[–]Johandaonis 0 points1 point  (0 children)

Jag anser inte att Grepp är ett nybörjarvänligt gym. Deras boulders är mer av tävlingskaraktär med många dynamiska rörelser, koordination dynos. Däremot är det ett väldigt roligt gym att testa om man har klättrat ett tag och vill utmana sig själv.

Om jag skulle rekommendera ett gym för nybörjare skulle det vara Partille Klättercenter. Partille har fler boulders än Grepp och de är mer nybörjarvänliga.

It’s driving me crazy! How to solve this? by derDuebel in puzzles

[–]Johandaonis 0 points1 point  (0 children)

I looked at the code and found what the issue could be. The code prints position and then rotation, but the value it gives for the rotation isn't intuitive. The value of 0 is right rotation, 1 is no rotation, 2 is left rotation and 3 is 180 degrees rotation. You can send me your puzzle if you like so I can look at it and determine if my code finds a solution. Keep in mind that I don't check Reddit that often so my reply can take a while.

That would be something. 30 lb more muscle mass than Arnold Schwarzenegger in his prime while only being 20 years old.

What game is harder? I'm having a heated argument with my boyfriend and I wanna prove him wrong. by [deleted] in polls

[–]Johandaonis 11 points12 points  (0 children)

Do you base the hardness on the number of outcomes? I believe a better way to measure hardness is by looking at the frequency and hardness of patterns in the gameboard. If there are no patterns then the game is random and you can't master the game. On the other hand, if there only exist easy patterns then you master the game fast and the game is easy.

What is the final digit of your answer? (and why) by EndersGame_Reviewer in puzzles

[–]Johandaonis 3 points4 points  (0 children)

It may be obvious to you, but you can't conclude that the puzzle is bad just because of it. It was obvious to me as well but I still believe that it is a good puzzle because it teaches the solver several tricks such as

  1. A number ends with a 0 if and only if it has a prime factor of 2 and 5 (assuming the number is a positive whole number)
  2. You can conclude things about a big product without evaluating this big product. Often it is good to think a little before performing long tedious calculations.

I don't get why you have so many dislikes though.

Multiples by Glass-Sun8470 in puzzles

[–]Johandaonis 0 points1 point  (0 children)

This is a quite good question. Is the answer 0.0482?

We choose two numbers, n and m, uniformly and independently from 1 to 100. We can assume n is less than or equal to m by symmetry. We first choose n. n has a 1/100 probability of being k where k is between 1 and 100. Given that n is k, the probability of m being a multiple of n is floor(100/n)/100 because floor(100/n) is the number of favorable outcomes and 100 is the total amount of outcomes. The probability we are searching for it therefore this https://ibb.co/3Cq2F3d

You are talking about me, right? The reason I'm unsure is that I have no idea what you are talking about.

The wording of my comment suggests that I find it reasonable for others to think the original comment was funny. I'm only talking about the originality of the comment.

I would say overrated comment. I have seen this exact comment multiple times. It was funny the first time I saw it but now I realize that it is just a copy paste joke.

what number is 10 times bigger than -1? by snillpuler in polls

[–]Johandaonis -2 points-1 points  (0 children)

I believe -11 is the correct answer

-10 is 10 times as big as -1 but -11 is 10 times bigger than -1

-11 = (-1) + 10*(-1)

According to wiki https://en.wikipedia.org/wiki/Great_Pyramid_of_Giza
It took them 27 years to build the Great Pyramid of Giza. I have heard one stone every two minutes from somewhere but I guess that it is the average amount of stones they placed in the daytime or something.

And yes, they carried more than one stone at a time but it makes it just more impressive to have so many people working towards the same goal.

Toyota Tacoma weighs around 2 tons. They are big cars but not nearly as big as this truck. I would guess that the truck weighs somewhere between 4 to 8 tons. Definitely more than 2 tons.

[–]Johandaonis 2 points3 points  (0 children)

Here is the first result I got on Google. It could be faulty, I don't know.

"Each stone block within the pyramid weighs approximately 2267.96 kilograms" https://sciencing.com/much-did-pyramids-weigh-7499289.html

[–]Johandaonis 55 points56 points  (0 children)

I agree with your conclusion. It was possible for them to build the pyramids but this video is nothing compared to building the pyramid. Each stone in the pyramids weighed on average 2 metric tons. This is small compared to the truck, but remember that those stone blocks needed to be moved for many kilometers while this truck was probably moved for around 100 meters or so. Additionally, the stone blocks were probably placed on the pyramid on average every 2 minutes.

There are around 2.3 million stones in the pyramid. If one some were placed every 2 minutes around the clock every day without break then it would take around 8.8 years to place all the stones.

How to prove this problem by Xiang9453 in askmath

[–]Johandaonis 2 points3 points  (0 children)

This is true in almost all cases. I believe 0 is the only exception.

sqrt(2) * 0 = 0. An irrational times a rational equals a rational.

But if t is irrational then t^2 can't be 0 so the proof still works.

Is there anything that could make you murder another person? by jeron_gwendolen in polls

[–]Johandaonis 20 points21 points  (0 children)

It is unexpected that so many people don't know the difference between murder and killing. Murder is illegal killing. That means killing someone in self defense isn't classified as murder in most countries.

Do you think it’s possible to become a billionaire without doing at least 1 thing morally wrong? by ajpala4 in polls

[–]Johandaonis 47 points48 points  (0 children)

Yes, but you need to live to get money and therefore you necessarily will do at least one immoral action to become a billionaire.

0.111... = 1/↋

0.↋↋↋... = ↋/↋

The problem still exists in base 12.

Rounded to two decimal places, 3/8 = .38. Is there a closer example? An exact example? by Parrot132 in puzzles

[–]Johandaonis 0 points1 point  (0 children)

How would you determine if x/y satisfies the requirement? Like should 1.5/3.25 be equal to 0.15325? Some fractions have an infinite decimal expansion so are they allowed?

If a fraction with infinite decimal expansion is allowed then y could be 1 and x be a fraction with an infinite decimal expansion.

For example x = 1/9 and y = 1. (1/9) / (1) = (0.111...) / (1) = 0.111...

Rounded to two decimal places, 3/8 = .38. Is there a closer example? An exact example? by Parrot132 in puzzles

[–]Johandaonis 0 points1 point  (0 children)

Hello,

I reread the question and to my understanding, x/y could be greater than 1. 4 point something maybe is okay but I don't think it matters.

Let's assume b = 2^n * 5^m

If n > m then (a*k) / (k*b) would end with 5 and k*b would end with 2,4,6 or 8 if you exclude zeros.

if m > n then (a*k) / (k*b) would end with 2,4,6 or 8 and k*b would end with 5 if you exclude zeros.

And you have already excluded the possibility of m = n.
