Tim can do it twice as fast as hardy- this means when both are working together the total is 3x hardy's speed.

After 1/3 of packing is done, tim comes to help.

it would take 2 hours normally to pack the remaining 2/3 but at 3x the speed it takes 2/3 HOURS instead of 2 hours, so only 40 minutes?

Alone, it would take 40x3 + 60 = 180, 3 hours for hardy alone. Let me know if anything is errorous.

Line with slope 1/3, or slope 1/5?

For slope of 1/3, you go right 3 every 1 you go up: 1x/3 = y, x = 3y

Similarly, 1/5 is 5 for every 1.

Now, you see, the greater the slope, the steeper it is.

1/3 > 1/5

Thus, 1/3 is steeper.

Sure! Give me a second to draw up an image.

Ok, it's a bd image.

Basically, your image (D) is basically rotated 180 degrees- it's a reflection, so as you can see it's now symmetrical

Then, we reflect again(now as you can see it's still symmetrical but this time across line m)

D will be reflected so that it's "flipped horizontally"

Then, you flip that again, I'd say it would be back at "D", like it appears.

NOt the most complete, since I hope you don't copy LOL, but if you want a more detailed answer just reply- I might not be active too much, but I'll check every so often.

You walk each dog 20 minutes.

For every 20 minutes you get 2 dollars.

You walked 42 dogs.

You claim you are a "smartmathman".

You should easily know it's 2 dollars per dog, since you walk a dog for 20 minutes and each 20 minutes is 2 dollars.

They're gone.

Most won't come back.

Many people have left this forum.

For what reason, there are many-

And many of which I am uncertain of.

Many do leave, but the most missed are the top people as you mentioned.

When you leave and are inactive for a bit, you are no longer on the leaderboard.

How many values do you want?

There could be many values of this.

To solve an equation with two variables you must have two equations.

Saying so and so = [does not insert value here]

is not very useful to solving.

60/10 = 6 feet per second.

25/5 = 5 feet per second.

Person 1.

It appears you would not be able to repeat the previous problem under examination conditions.

Your new question, again, suggests that.

Again:

Prime factorization.

1) You said 17 is incorrect

3.55687428E14

That is 17!.

I am quite confused as how that is a factor of...

80325.

Ok then, tell us the answer.

9! is already 360 K or so, no point of going further.

Dragon did not try to solve this problem, not even sure he gave it more than 6 seconds of thought.

I agree with your answer, guest.

Hi tacobell, I think that Violynx is correct.

Had you actually tried to solve this question instead of trying to get others to do your work, you would not assume "oh well it is probably a 2 digit number"

For your information, a "two digit number" factorial, the least being 10!, is in the millions.
