The soup is up.

Answer

1. "You're up." likely comes from old stage performances where a person had to walk "up" the stairs to get onto the stage. So, it's short for, "You're up on stage next." I can't find any clear information about that, so I'm just guessing about the origin.

In restaurants, people often say, "Order up." which means it is ready to be taken to the table. So, "The soup is up." would make sense in that situation.

2. Am I going to be fired?
Are you going to fire me? (this one is correct)
Do you want to fire me?

Be careful about the order of the sentence: Subject + Verb + Object.

3. Where can I find the information for this blank?

4. Correct

5. I don't quite understand what you're asking in this question.

Answer

I have to put together a 500 dollar packet of bills from the cash box for the next cashier to start with. There is a need for small bills because we need a lot of change.

I am going to put together the 500 dollars starting with the smallest (denomination) bills to the largest.

NOTE: The last sentence doesn't work very well because I can't quite visualize what you are saying you will do.  It would help if you could explain how you would put together the packet of 500 dollars.  If you like, you can send me a few sample packets so I can see how you put them together.  (Please laugh.  That last sentence was a joke but the rest of the note was sincere.)

Answer

Also... you need to be clear about what it means to "be up".  It is possible that saying someone is "up" means that they are happy and enthusiastic as opposed to "being down".

However, it can also mean "it's your turn".  In baseball, the person who is batting is said to be "up at the plate" but, as others have mentioned, in general usage, it just means it is your turn to do something (such as to speak).

If you say "I'm up now, I have to go.", that usually means "I can't talk to you because it is my turn to do something (e.g; speak to the group)."

To say "My time is up.  I have to go" means "The time that I have available to spend with you is over.  I have to go".

Answer

I've never heard the phrase "the soup is up" but I imagine it has the meaning that others have given (i.e. that the soup is ready to eat).  The phrase that I've heard (and it's not so commonly used anymore) is "the soup is on".  I think the origin of that phrase is "the soup is on the table".

Answer

"You're up" = it's your turn

"The soup is up" = the soup is ready now.
