Before beginning an apartment search you should know what you're looking for in terms of size, price and neighborhood. You should also know your credit score.
A score is equal to 20.
No, it is not. Grade can be a verb with distinct meanings (to score, to level) or a noun with the same general concept (a score, a level or level rise). It can be a noun adjunct in terms such as grade crossing.
An acute angle is one which in geometrical terms measures between 0 and 90 degrees.
