How to calculate value of expressions when a = 22
Round the answer to three significant figures:
77 3 a
for this one I am not sure if I do 77 3 ( 22 ) = 1.17 or 77 3 ( 22 ) = 56
Sorry if this is written in a confusing way.

77 3 a means you will just replace a in the formula with 22.
Therefore, 77 3 22 or, when rounded to 3 significant figures, 1.17

How to convert feet and inches to decimal feet?
What is the proper way of converting feet inches to decimal feet?
For example
15 ft - 4, 1/8 inch = 15.34'
I understand that the 15 get's moved but how do you take 4 1/8" and turn that into 0.34?

Where does this fraction come from in this integral?
So you have the integral:
3 v 200 4 v d v
I tried to do u-substitution at first with u = 200 4 v, but I could not get the correct answer which is:
3 4 v 150 4 l n ( 200 4 v ) + C
In the worked solution, they did not use a u-substitution. The first integral becomes:
3 4 + 150 200 4 v d v
And I cannot see what technique they used to get that. I worked out that if you actually add the 2 fractions you end up back at the first integral, but I do not see how they worked out that is the way it should be re-arranged. I also don't understand why my u-substitution didn't work. Should a u-substitution have worked? I'm still trying to get my head around this integrating of fractions.

Finding all possible pairs of positive integer values
The ratio of the sum of two positive integers to their difference is 7:5. If the the sum of the two numbers is at most 25, find all possible values for the pair of numbers.
Let m be the first positive integer.
Then m 6 is the second positive integer.
This gives m = 21.4, but now I'm stuck?

Calculate weight based on body fat percentage
This is the YMCA method for determining body fat percentage for a female based on weight and waist size:
76.76 + ( 4.5 A ) ( 0.082 B ) B = C
Where: A = Waist size in inches, B = Weight in lbs, C = Ratio of body fat.
I would like to re-arrange this formula to solve for B.
ie: determine target weight based on waist and body fat ratio.
Thanks in advance! :-)
