're' means concerning or regarding something. You get it with emails as well so if someone clicks on 'Reply' to one of your emails, then when you receive the reply you will see it has the same title you gave it but with re: in front of it (unless the recipient edited it)

re actually comes from the Latin for 'thing'

I am afraid Reckless19 has misunderstood your question and had simply given you the definition of a black body.

Black body radiation is the distribution of wavelenths that would be expected from a black body raised to a temperature of T Kelvin degrees. You should be looking at work done by Max Planck and the appropriate Wikipedia place is actually this:

Note the difference. In my link there is a hyphen between the 'black' and 'body' instead of an underscore.

It is extremely difficult to walk in a liquid, particularly if you don't have legs and wings aren't much use either. How else will they get from A to B?

If the original price was £500 then that represents 100%

A markup of 20% will therefore take that to 120% so you need to calculate 120% of 500

ie (120/100) x 500


If a discount is being offered and the price is being marked down then the process is similar.

The original price of £500 represents 100%

A markdown of 10% will therefore take that to 90% so you need to calculate 90% of 500

ie (90/100) x 500

This does not need reporting because it is such a well known scam. I first received such an email about 10 years ago and variations still turn up from time to time. It is generally referred to as THE NIGERIAN SCAM and google will turn up hundreds of thousands of hits fot it. I once came across a site that tried to play them along and published the correspondence as the scammers were gradually duped into making fun of themselves.
