Challenge#4: Puzzles-a-Plenti

[Neo]

You know how they have those random puzzles in RE that don't make much sense? Well we've got those too! Hooray!
(just play along)

Billy is standing behind Rebecca and at the same time Rebecca is standing behind Billy. How is this possible?

A man decides to buy a zombie. He pays $60 for it, and he is very content with the flesh-eating undead. After a year, the value of the zombie has increased to $70 and he decides to sell the zombie. But already a few days later he regrets his decision to sell the blood-thirsty zombie, and he buys it again. Unfortunately he has to pay $80 to get it back, so he loses $10. After another year of owning the zombie, he finally decides to sell the zombie for $90. How much total profit does the man make?

The T-Virus is released in Raccoon City. The virus doubles in concentration every minute. After exactly 20 minutes the entire city will be covered in the virus. After how many
minutes will half of the city be covered by the virus?


Please post answers by 9pm CST Thursday.
I will post a tie-breaker if both tribes answer these questions correctly.

10$

I also know the answer to #1, but Id rather not ruin it. Too easy IMO. The third one im not so sure on though...

Oh yea, Im just a reject, I dont matter.

[Perfect Stu]

is the last one supposed to be "the virus doubles in concentration every 'MINUTE'?" instead of day, or is that the way it's supposed to be?

yes that's right, sorry I've made the correction

[Jonbo298]

The first one is too easy also. Its a mirror

[Neo]

If you guys want to submit your answers tonight instead of tomorrow, that's perfectly fine. If you miss something though you won't be able to correct it.

Neo, don't go making the next challenges this easy =¬Þ

[Neo]

Alright both tribes seem to be having no probs with these questions, so here are some additional questions. If both tribes are correct then the one which comes up with the answers first will win immunity.

What word, expression, or name is depicted below?

FAREDCE

What is the smallest integer which can be expressed as a sum of two squares three different ways? The answer is less than 500.

Using exactly two 2s and any of the standard mathematical symbols, right down an expression whose value is 5.

What word, expression, or name is depicted below?

can you explain it a bit more please?


also for the "Using exactly two 2s and any of the standard mathematical symbols, right down an expression whose value is 5." thing, how many symbols can we use?

Are "2 +4" and "4+2" different ways?

EDIT: On a similar note... Can I use "2 + 4 + 4" assuming both 2 and 4 were squares?

[Neo]

No. That is a hard one.

You will have the sum of different squares, so x^2 + y^2 = z^2 + a^2 = some number, for example.

And finally, do the numbers like X and Y have to be integers?


for example... (0.5 ^ (1/2)) ^2 would equal 0.5. Is it acceptable?

[Neo]

The answers are all integers.
