An alloy is a metal made by combining two or more metallic elements. You mix an alloy that contains 14% copper with an alloy that contains 24% copper to make 100 pounds of an alloy that is 18% copper. How many pounds of the 14% alloy was used?

In a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Choose a second initial value that is 0.01 greater than the initial value from question 9. iterate it using the function, f, ten times. if necessary, you can round your results to the nearest ten-thousandth.
