Are you actually going to do any of these for yourself?

You are slowyly getting us to do every one for you. 

Please do not do this!

anon has given you plenty of help.  You should work out your final answer fo yourself!

Well if she filled it with an extra 4.25 gallons then before she filled it it must have has     n - 4.25    gallons in it.

Thanks Alan and Nauseated.

I now get that the radar will have to clock the oncoming car at a smaller speed then what the car is really travelling at.

Each of your pics gave me different info and they both helped a lot .

Alan I can see that your pic gives me the desired answer but  I can't quite fathom why the pic is right.  

I am still contemplating the actual maths of it.  Is it possible for you to show me mathematically, with the units, why your answer is correct?       Why is the triangle drawn like that? Why is the right angle at the police car ?

Is that to seperate the x and y components of the velocity relative to the police car?  Maybe there is a glimmer of understanding coming.

Ik Q2

I'll do a simple example to show you

A1,A2,A3,B

how many ways can these be placed in a line   4*3*2*1=4! ways.

Now lets forget about the B for a moment, how many ways can the A's be ordered. that would be 3!=6 ways

So if you treat the As like they are all the same there will be   4!/3! ways of arranging them.  That's 4 ways.

BAAA, ABAA, AABA, AAAB     THAT IS IT.

-------------------------

now marmalade is made of      m m a a a r l d and  e

9 letters so if they were all different there would be 9! ways.

But

there are 2 Ms and 3 A's

so that is      9!/(2!*3!)

Well I am sure that would be activities happening on the beach and near the shore. Plus you would be listening to the surf all the time.  No I do not think it would be boring.

However, since I am not really a beach person, I would prefer a view of a river or lake where there was lots of activities  (but no water skiing, because it is really noisy)

I would love to live on the edge of a beatiful lake or river or harbour.  :))

Yes my room would not look sterile like that one.  I would have all my things around me. :))

Thanks Alan,

I have altered my answer a little but I still do not understand what is wrong with my logic.

Can you please take a look and talk me through it?     Thank you.   

Hi Rosala,

It was not the formality that I was admiring, it was the view and the big bearuiful verandah !!

And yes it would be far more expensive than what i could afford.  :((
