Euler Piruleta Vs. The 2€ Coin

Euler Piruleta was once a rascal and he didn’t manage to obtain his ESO degree. Now he has been threatened that he will be expelled of Matfor if he doesn’t pass the only exam he failed that time: Similarity and Trigonometry!  

Since this is now your area of expertise, can you help Euler to solve this problem?

How far do we have to place a 2 coin from our eye to completely cover the Moon?

The information below is everything you will need to solve it:
-         Moon’s Diameter: 3476 Km
-         Distance Moon-Earth: 384.000 Km
-         Coin’s Diameter: 28 mm

Tip: you know how this works draw the situation described and you will be able to solve the problem! :D

You will get 20 coins if you send the right answer and 20 extra coins if you explain how you got the code!

Deadline: February the 9th.

PS: Cesar Romero and TaniaPopcorn have received 40 coins and TheHeadhunter 20 for the solution of the previous challenge!

This is a song I've been particularly enjoying these days...

Euler Piruleta Vs. The Box

Euler Piruleta feels exhausted after those past two ordeals he went through (the zombies and all that stuff). Luckily enough for him, he had a great Christmas time with his family (some strange fellows though).

His grandfather knows he keeps risking his life to help the people of Maftor, so he decided to give him his invisibility cloak he once had stolen from Harry Potter.



Everything seems quite straightforward so far, but Euler’s grandfather is some sort of a joker and thus he set a lock in the magic box. Euler must get the code to open it if he wants to retrieve the invisibility cloak trapped inside!

The code is formed by the 10 numbers which should be written in the sentence below in such way that it makes sense (including the numbers written in the gaps!)

In this sentence the number of times the 0 appears is ___ , the 1 is ___ , the 2 is ___ , the 3 is ___ , the 4 is ___ , the 5 is ___ , the 6 is ___ ,
the 7 is ___ , the 8 is ___ and  the 9 is ___ .

That is, you have to complete those 10 gaps using numbers from 0 to 9 (which can be repeated) to get a coherent sentence. For example, if you use only the number 1:

In this sentence the number of times the 0 appears is 1 ,
the 1 is 9 , the 2 is 1 , the 3 is 1 , the 4 is 1 , the 5 is 1 ,
the 6 is 1 , the 7 is 1 , the 8 is 1 and  the 9 is 1 .

It would be wrong because you can find 2 numbers 9 in the sentence and not 1!!

Help poor Euler to get his invisibility cloak!!

You will get 20 coins if you send the right answer and 20 extra coins if you explain how you got the code!

Palanquilla's Song: You probably don't know who Leonard Cohen is and I guess you will not like his music (but you will in the forseeable future, trust me). Anyway, if you play this song and wait to the position 04:26 you'll hear Palanquilla's fake laughter.
