The worlds first riddle!

Mark:

OPPOSITION
Assuming circular orbits, 779.88 days.

T/687 + 1 = T/365.25



It would appear Mark is a Nutler Fizzerwhatdoyoucallit


The Earth moves at .985626283 degrees per day (360 divided by 365.25).
Mars moves at .524017467 degrees per day (360 divided by 687.0).
Therefore, Earth has a net gain on Mars of .461608816 degrees per day (obtained by subtracting Mars' rate from the Earth's).
So at .461608816 degrees per day, how many days would it take for the Earth to travel the 360 degrees in order to 'catch up' to Mars?
360/.461608816 = 779.88 days.




The mythical town of A2Know had a population of 10,000 people in 1930. Since then, the population has doubled every 23 years.

(For example in 1953, the population equalled 20,000; in 1976 it was 40,000; in 1999, it was 80,000 and so on).

What was the population in 1980

who in the world gave you the inpresion that all newbies are idiates? i happen to be a very intelligent person for my age. i usually don't care what people say about me, but when they begin to acuse me of being stupid or ant kind of dumb, that just pisses me off.

I hope to talk to you more in the future on my topic in the video games forum. You seem oddly inteligent. An intlectual that is smart enough for me to conversate with.

1. You're off the mark with your accusation.
2. You seem to have an inflated opinion of yourself (unless you're about eight years old).

i am over opinionated about myself. but at least i can admit it. thanks for calling me what i am.

yugirules14,

Nobody said anything to you, and nobody called you or any other newbies idiots. Did you have a bad dream and think you were in a conversation you weren't?

no... i just like to talk. and maybe they didn't say it here. but they did say it. have you heard of runescape? they say it all the time i was talking out loud. and i just used any name.

so, by "they" you are referring to the rest of humanity...and you chose to direct your resentment at able2know, on this particular thread, for no particular reason...and you wonder why people insult newbs?

i searched for you and nobody at a2know has ever insulted you, or other newbs while youve been around.

Oh, I see you Guys have met Yugi, she and I go way back…to last Wednesday I think it was. We met in a strip joint in Phoenix AZ. I was just asking directions, she was a 300 pound, Russian single mother of six working her way through high school.

So may I say; Привет to you Yugi.



I Also note the population question confounded the greatest minds, even that of Yugi. Perhaps this will pose a lesser challenge, or perhaps not.



Scientists define the half-life of a substance as the time in which it will lose half of its radioactivity. For example, a substance with a half-life of 10 days will have 50% of its radioactivity in 10 days, 25% in 20 days, 12.5% in 30 days and so on.

A substance being tested is found to have 90% of its radioactivity after 12 days.

What is its half-life in days

[size=8]POPULATION
Oops - got distracted.

45125 (rounded to nearest integer)

P = 10000 * 2^((Y-1930)/23)

HALF-LIFE
1.824 days

T = 12 * (-log2(0.9))[/size]

you were way off. i live in indiana, i'm 14 and weigh 125 pounds.i don't have a job yet. and when i get older, if i have kids i'll kill myself or them. the little brats. i hate everything and every one. get it right. and even if that was me. i would not even try to talk to you . i'm an online talker only.

HALF-LIFE


Due to the huge disparity between our answers, I give the first part of my answer for consideration.

The number of half-lives a substance has undergone may be indicated by the formula:
Number of Half-Lives = (Elapsed Time/Half-Life)

For example, if a substance has a half-life of 5 days, then after 20 days, it has undergone 4 half-lives.

We will let 'n' = the number of half-lives for the next formula:

Amount Remaining = (1/2n)

So from the problem, we are told that the amount remaining is .9 (or 90%). Substituting into the second formula, we have: .9 = 1/2n

To be continued on the morrow…. :wink:

that's an interesting thought.

[size=8]HALF-LIFE
Oops. I solved the wrong problem. I figured out how many days elapsed assuming the half-life is 12 days.

78.9 days
H = 12 / (-log2(0.9))[/size]

Shame on you, Try. You should have known that was a different Yugi. This Yugi is at least three years from working in a strip joint, and probably another five years from weighing 300 pounds (somewhere in between will be a career change - I'm thinking circus). However, she didn't deny being Russian.

i'm mixed between white and black. i am loosing wieght like crazy weither i want to or not. i will never work at a strip clud. the people there are digrading and the people who go there are worse. i'm to smart for that. i scored higher than any one in my school , so you have no right to say anything about me.

She's talking about you, Try. You admitted to being at a strip joint last Wednesday. That makes you worse than digrading. Wait till she finds out about your career as a porn film special effects engineer...

That doesn't sound good.

nobody in your school knows how to spell 'loosing', 'wieght', 'weither', 'clud', 'digrading', or 'to'?

Try are you picking on little girls?
