The | ....|    bars are absolute value bars....so if the value inside is NEGATIVE , you just ignore the - sign and make it positive.....  | 2 1/2|  is just   2 1/2....   go man, go....

Sure.....

Step 1:

Step 2:

Step 3:

Step 4:

Voila....THAT is the answer !

Not enough information given.....  an  A+ encompasses a range of values as does a "B"......and we would need to know the weighted values of the original grade and the "B".....    sorry!

How BIG of a perfect square?  How tall are the walls?  What is the HEIGHT of the bricks?    Not enough info to answer this question......  can you provide some more info?

...agree!  Haha     or    1+1    or   2+ 2     or 'What is the meaning of life'    etc    

Just ignore the silly easy questions, or the people who are just trying to get their homework done by you.......

Move on.....

Just wait until Algebra 10 !   Haha

First ,   realize 10/3 pi   is the same as 4/3 pi

4/3 pi is in the 3rd quadrant so the sine AND cosine will be negative....the tangent and cotangent will be positive

4/3 pi radians  is equivalent to 240 degrees

sine is  -sqrt(3)/2   or  -.866     Cosine is - 1/2     tangent is sin/cos.... I think you can do that math.

Good luck with your studies!

But I still do not see a common ratio of 1/3...

a geometric series may simply be written as

a + a r + a r 2 + a r 3 + ⋯

and 1/3 does not fit the bill.......how did you get 1/3??
