This is a passive sentence because the subject (dollars) is being acted upon rather than performing the action.
This sentence is in passive voice. To change it to active voice, you could say "Five dollars were present."
Yes, the sentence "We were told to wait until five o'clock for the delivery" is in the passive voice, as the subject (We) is receiving the action (being told to wait), rather than performing the action.
Starting with a sentence in the active voice, you change the object into the subject. Then you add the verb "to be" in the appropriate tense before the root verb. You can add the former subject after the word "by" E.g. "John hits Jim" "Jim" is the object, so he is now our subject. We add the present tense of "to be", which in this case is "is" and the root verb "hit" and "by" followed by the former subject "John". The sentence reads "Jim is hit by John." In the past tense "John hit Jim" becomes "Jim was hit by John". In the future, "John will hit Jim" becomes "Jim will be hit by John." A more complicated example: "The revolutionary tribunal sentenced the poor man to five years hard labour." becomes "The poor man was sentenced to five years hard labour by the revolutionary tribunal."
The given sentence has got two clauses: First one is a main or principal clause, "Elena thinks" where the subject 'Elena' is first person singular which agrees with the verb 'thinks'. Second clause is a subordinate one: "five dollars are a lot of money". In this, 'five dollars', even though apparently a plural noun does work as singular noun, is the subject of verb 'are'. As 'a lot of money', the object of the verb 'are', is considered singular since the article 'a' makes it a singular entity, the verb 'are' does not agree with it. Actually the verb 'is' should be substituted for 'are' ("Elena thinks [that] five dollars is a lot money"). Hope this explanation clears the confusion.
You spell it like this: Forty Five dollars.....

Passive. The subject, "children," is not doing the action. Also, a sentence is passive when a form of the verb "to be" is followed by a past participle- in this sentence it is "were taken." To make the sentence active, it would have to state "Five children went to the zoo" or "Someone took five children to the zoo."
Yes this is an active sentence because it tells us who did the action(run). Passive sentences don't usually tell us who did the action(verb). Leonardo Da Vinci painted the Mona Lisa in the 16th century. In this sentence we know who did the action (painted) it was Leonardo. This is an active sentence. The Mona Lisa was painted in the 16th century. In this sentence we don't know who did the action (painted). This is a passive sentence.

You wrote it out in a sentence just fine in your question. "five million dollars"
I'll tell you when you give me five dollars.
Who is the subject of the sentence whereas whom is the object. For example: In the sentence "He gave Joe five dollars." who would replace "he" and whom would replace "Joe" to make the sentence "Who gave whom five dollars?".
If I have ten dollars and give you five dollars, then I have given you fifty percent of my ten dollars
What we have here is an incomplete sentence.
My dedication to the cause paid off, for we made five-hundred dollars!
