The meaning to life may still be unknown. But according to google, the answer to life, everything, and the universe = 42.

When put into the calculator, the square root of 0.81237 = 0.9013157049558162. Even I am a little confused, as I have not learnt much about this even though I'm already in high school.

21.60 or 21.6 divided by 1.35 equals 16.

9 + 10 = 19. If you are having trouble, try counting using crayons, your fingers and toes, toothpicks, etc. You can also try to input that into a calculator and it will solve the expression for you.

The unit rate is $9 per hour. If you are having trouble understanding, remember problems usually give hints. Two big example of hints for unit rates are the words "per" and "each." When something is taken away or added "per" hour, minute, second, week, day, etc. that is usually a unit rate.

I recommend using a compass, just like hectictar said. If you don't have own, practice drawing circles by moving the pencil around one point on a paper. If that still doesn't work, hold down the pencil on a part of a paper, preferrably the middle, at an angle. Then, turn the paper around either clockwise or counterclockwise. Just don't hold the pencil at a big angle or the circle will be too big. Good luck!

The exact same way you just said. 7/14.

 TMI.

4x + 8 = 7.2 + 5x =

x = (4/5) or 0.8.
