Problema da melancia

Enunciado:
Imagine-se uma melancia com 2 kg. Apenas 1% da melancia é matéria sólida, os outros 99% são água. Deixa-se a melancia ao sol e ela desidrata-se passando a ter só 98% de água. Quanto pesará então a melancia?

Resposta:
A parte líquida inicial é igual a 99% de 2 kg, ou seja, 2x0,99 kg
Seja P a perda da água após a desidratação,e como tem 98% de água,
(2x0,99 - P) / (2 - P) = 0,98
2x0,99 - P = 2x0,98 - 0,98P
P = 1 kg

O peso da água inicial era 0,99 x 2 = 1,98 kg
Como perdeu 1 kg ficou com 0,98 kg de água + 0,02 kg da parte sólida fica 0,98 + 0,02 = 1kg (final)

Lamento, mas estás errado.

Não, não sou daquelas pessoas que "só dá valor ao que tem depois de o perder". Sei bem o que tinha. Sempre soube, e sempre lhe dei valor. Mas não estava (nem nunca estarei) disposta a mudar. Há-de haver alguém que me queira exactamente como sou. Se não houver, tenho sempre a família e os amigos.

Last Kiss

Oh where, oh where, can my baby be?
The Lord took her away from me.
She's gone to heaven so I've got to be good,
So I can see my baby when I leave this world.

We were out on a date in my daddy's car,
We hadn't driven very far.
There in the road straight ahead,
A car was stalled, the engine was dead.
I couldn't stop, so I swerved to the right,
I'll never forget the sound that night.
The screaming tires, the busting glass,
The painful scream that I heard last.

Oh where, oh where, can my baby be?
The Lord took her away from me.
She's gone to heaven so I've got to be good,
So I can see my baby when I leave this world.

When I woke up, the rain was pouring down,
There were people standing all around.
Something warm flowing through my eyes,
But somehow I found my baby that night.
I lifted her head, she looked at me and said;
"Hold me darling just a little while."
I held her close I kissed her - our last kiss,
I found the love that I knew I had missed.
Well now she's gone even though I hold her tight,
I lost my love, my life that night.

Oh where, oh where, can my baby be?
The Lord took her away from me.
She's gone to heaven so I've got to be good,
So I can see my baby when I leave this world.

Five stages of grief (Kubler Ross)

1. Denial (this isn't happening to me!)
2. Anger (why is this happening to me?)
3. Bargaining (I promise I'll be a better person if...)
4. Depression (I don't care anymore)
5. Acceptance (I'm ready for whatever comes)

Doors - The End

This is the end
Beautiful friend
This is the end
My only friend, the end

Of our elaborate plans, the end
Of everything that stands, the end
No safety or surprise, the end
Ill never look into your eyes...again

Can you picture what will be
So limitless and free
Desperately in need...of some...strangers hand
In a...desperate land

Lost in a roman...wilderness of pain
And all the children are insane
All the children are insane
Waiting for the summer rain, yeah

Theres danger on the edge of town
Ride the kings highway, baby
Weird scenes inside the gold mine
Ride the highway west, baby

Ride the snake, ride the snake
To the lake, the ancient lake, baby
The snake is long, seven miles
Ride the snake...hes old, and his skin is cold

The west is the best
The west is the best
Get here, and well do the rest

The blue bus is callin us
The blue bus is callin us
Driver, where you taken us

The killer awoke before dawn, he put his boots on
He took a face from the ancient gallery
And he walked on down the hall
He went into the room where his sister lived, and...then he
Paid a visit to his brother, and then he
He walked on down the hall, and
And he came to a door...and he looked inside
Father, yes son, I want to kill you
Mother...i want to...fuck you

Cmon baby, take a chance with us
Cmon baby, take a chance with us
Cmon baby, take a chance with us
And meet me at the back of the blue bus
Doin a blue rock
On a blue bus
Doin a blue rock
Cmon, yeah

Kill, kill, kill, kill, kill, kill

This is the end
Beautiful friend
This is the end
My only friend, the end

It hurts to set you free
But youll never follow me
The end of laughter and soft lies
The end of nights we tried to die

This is the end

Tradição dos Maios

Os Maios são bonecos em tamanho natural, feitos com pano e cheios de palha, dispostos na Estrada Nacional 125, na zona entre Quartim e Bias do Sul (Olhão). Eles celebram o dia 1º de Maio, sendo uma tradição bem antiga, que remonta a ancestrais rituais pagãos de celebração da chegada da Primavera. Na sua maioria, os autores dos bonecos e das quadras que os acompanham satirizam casos sociais ou políticos, bem como figuras da terra e lendas locais. Outros recordam antigas práticas, como os casamentos à moda antiga, a escola, os funerais, as festas e os piqueniques, comendo caracóis e nêsperas, como é tradição em Maio.
