In science what does "pay back time" mean?
913047
It means getting back what was taken. It really is as simple as that because even the most complex formulas need the proper pieces for it to work.

Your main question is true.  I learned that in economics class.  The rest of the stuff really is true, but does not entirely relate to your main question, so you kind of lost me with all that.  But it is true--there is no free lunch and that is suppose to mean that even when something is told to be free, your time is not and so forth.  :)

This phrase refers to looking back at what has happened in the past and everything seems to be clear (like perfect vision or eyesight which is 20/20).  Things make sense only after they have happened.  You have the benefit of seeing what happened at the beginning, middle, and end only after time has passed.  You can't go back and change things, but at least you have knowledge now about what could happen in the future for similar events.  The phrase is usually used in reference to something bad that happened or a missed opportunity, that had you known what you now know, you would have done things differently.

The most common usage of the term is in criminal law, which is what I presume you are asking about.  Sometimes, as part of a plea bargain, the defendant will plead guilty and be sentenced to "time served".  In other words, the time that the person has already served in custody from the time of the arrest to the time of the plea bargain is sufficient punish for the crime.\n\nA sentence of "time served" means they are now eligible for release assuming they comply with any other terms of the plea bargain.

"Forever in your debt" means that you are very grateful for something that someone has done and do not think you can ever truly repay them for their kindness.  It is not literally an actual debt of infinity.\n\nIndebt is a word, albeit an old one and it means just what it looks like: in debt to someone.

Depends.\nWe get paid by the year, not by the hour or day.  So, we get paid for the work we do in the school year.  My district offers a choice: you can take your paycheck divided for 10 months (so no summer pay, but bigger schoolyear paychecks) or 12 months (paid all summer too, but smaller checks.)\n\nSo, it depends on the district.  But we're not getting paid for work we're not doing, we're just spreading out the "wealth"!

The same way you are motivated to work 8 hours a day.  You are rewarded with money.  Well an education will net you a much better salary when you start earning.  It's called delayed gratification.  It's kind of like that donkey following the carrot on a stick.  That donkey keeps following that carrot because he knows he will eventually get it if he keeps moving forward.

Salary can mean monthly or annual pay.  It also means that you are paid a set amount, for example $50,000 a year, to work regardless of how many hours you work a week.

it means that the sum is broken down in to hours and you are paid for the hours worked for example \nyou take a job that is 20k pro rata and \nyou work part time - say 3 days a week (24hours). \nthe 20K is split in to weeks (£20000/52wks = £385.62 per week),\nthen split in to working hours (£385.62/40hrs = £9.64 per hour) \nThen it is built back up again to get your true salary -\n£9.64 per hour * 24 hours = £241 per week\n£241 per week x 52 weeks = £12,532\nthe last figure is the amount you can aexpect to get paid for working 24 hours a week on a pro rata of £20k\nhope this helps

While i'm not certain, my guess would be that it means "i'm getting four hours of overtime-pay"  Overtime pay is usually what you normally get paid per hour plus half of that per hour if you work more hours than in your contract or originally decided with the employer (for example, instead of 6 dollars an hour for 40 hours a week, you work 44 hours hours per week.  You would get 40 hours at 6 dollars/hour and then 4 hours at 9 dollars an hour)\n\nHope this helps!

It depends on the type of funding you receive.  \n\n* Grants, by definition do not need to be paid back, nor do scholarships and fellowships.\n* Loans, by definition, DO need to be repaid (YES, loans are still considered Financial Aid).  \n* Federal Work-Study is basically a federally subsidized job -- you don't need to repay it but you're paid only as much FWS as you actually earn.

The way student loans work (or at least federal ones) is that you have to apply for them, through the Financial Aid office at your school.  After you apply, you will find out what kind of Aid you are eligible for - subsidized loans, unsubsidized loans, grants and workstudy.  Grants and workstudy do not have to be paid back.  After you graduate, unless you defer repayment, you are given a 6 month grace period before you must start to repay your loans.  There are 3 different categories for repayment, they each are a different monthly payment.  It all depends on what you can afford.  The longer you drag out repayment, the more you end up paying because of interest.
