I suppose it would be 13*5*7*19.

If we add 10 to any of the other factors it will be more than adding 10 to the 3, so I think the next is 8645.

Week 1: 

3$/gallon, 60 total, so 60/3 = 20 gallons.

4/gal, 60 total, 60/4 = 15 gal.

5/ gal, 60 total, 60/5 = 12gal.

Adding 20+15+12 = 47 gal.

Divide this by 3 weeks = 15.666666666666667

So rounded is 15.67

So 530 mph for 1325 miles. How long does it take? So we have a number t for time.

530t = 1325

isolate t, t = 1325/530

You can plug this into a calculator and solve it yourself.

I'm assuming this is a typo.

He traveled up for 12 min at 15mph, then went down 30mph. So if you are travelling at 30/15 = 2 times the speed your time is decreased by 2 times, so 12/2 = 6 minutes.

60/5 = 12 minutes at 15mph = 15/5 = 3miles. Similarly 60/10 = 6 minutes at 30 mph = 30/10 = 3 miles.

He travels a total of 6 miles in 12 + 6 = 18 minutes, so that's 1 per 3 minutes. 60/3 = 20, so 20*1 = 20 mph average speed.

The concert ends at 8:40 and takes 22 minutes to get out, so 8:40 + 20min = 9:00, + 2min = 9:02.

That's 9+ 12 = 21 o clock so 21:02. Thus the answer is 21:15.

Hello x^2 it's good to see you back after you were kinda inactive for a bit :)

It's not about hearts. It's about your dedication, ability, and quality of answers. You could have 10 times more than melody or cphill but if they are incorrect you still won't be moderator.

you earn the position of mod, you don't waltz into here and ask if you can be one.

Sorry for the late reply.

We choose the two paired ranks in \(\binom{13}{2} = 78\) ways and the remaining rank in \(\binom{11}{1} = 11\) ways.

Now you know this calculate the number of ways you can pick the suit.

Good luck!

Your effort to get that 1 point is commendable though.

Me: That's just 1 point. Meh.

Oh no it's fine :)

You did a much better job than me than I would be able to do with digital art

My 2s look like z's and... *casually looks away*

They look ugly.

;)

Great explanation!
