A family is purchasing concrete in order to create a foundation for a rectangular outdoor patio. The rectangular patio is to be 15 feet wide and 17 feet long. To meet
specifications, the concrete must be poured to a depth of 6 inches. Large amounts of
concrete can be purchased by the cubic yard. How many cubic yards of concrete will it
take to construct the patio. Round your answer to the nearest tenth.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
