Suppose you want to buy new carpeting for your bedroom. the bedroom floor is a 9 foot by 12 foot rectangle. carpeting is sold by the square yard. how much carpeting do you need to buy?

  12 square yards

Step-by-step explanation:

The bedroom floor is a rectangle 3 yards by 4 yards, so has an area of ...

  (3 yd)(4 yd) = 12 yd²

You need to buy 12 square yards of carpet.

1 yard = 3 feet

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
