Hi, Its hard to help very well with out context. Your version might be correct but maybe this would be correct: "Payments for services shall be made by the client in the national currency of Ukraine, hryvnia (UAH). The cost of the services, specified in the Annexes, shall be transferred in a cashless form to the contractor's current account based on the invoice issued by the contractor within ten (10) business days after issued invoice."

It definitely means that the auditions are rigged. Whoever wins them, wins them because of who they know or some kind of sneaky strategy they used, instead of pure talent.

It could also mean that her ponytail was moving around a lot because of a bouncing/ bubbling personality.

You can use Pandora.com and just type in "rock music". NPR.org is not a radio station but a website. However they have a music section with radio streams available and music tap where you can find a rock genre to search for good bands. You should also browse their "tiny desk concerts" section, it has great videos!

These both seem like informal questions. It would usually be "Are you sure" instead of "you are sure". However, I have heard people say "You are sure we are not forgetting anything?". I think it would be considered slang or improper though. I do not think you should ever use "don't" in this sentence, because "don't" is a contraction of "do not", which is for future tense. The question (I think) you are asking would be either present or past tense. Hope that is clear and helps!

Spending time with the people I love.

It means he will be visiting Cairo on the next Monday.
