And animals weight change from 12 pounds to 16 pounds what was the percent increase to the nearest whole number
amm1812
That's a 33% increase.

I calculated this using the formula:

\frac{|n-o|}{o} * 100

Where n = the new value (16 in your question), o = the old value (12 in your question) and the result is outputted as a percent increase.  You can check that this is correct by finding 33% of 12, adding the result to 12, and checking that the result equals your "new" number.  

Note that 33% is only an approximation as your question requires a number rounded to the nearest whole.

The diagonals of a square measure 14 cm. Which is the length of a side of the square?
Kryger [21]
The length of the side of a square is 7√2.

To find the diagonal, you multiply one side of the square by √2. To find the side of the square, I just divided 14/√2 and got 7√2.
