Without dividing, determine which of the following represent terminating decimals.
1)
\(\displaystyle{\frac{{{72}}}{{{81}}}}\)
2)
\(\displaystyle{\frac{{{21}}}{{{28}}}}\)
a. Is
\(\displaystyle{\frac{{{72}}}{{{81}}}}\)
a terminating decimal?
b. Is
\(\displaystyle{\frac{{{21}}}{{{28}}}}\)
A) Yes, because the only factors of the denominator, 81, are 2 and 5.
B) No, because the only factors of the denominator, 81, are 2 and 5.
C) No, the denominator of the simplified fraction contains a factor other than 2 or 5.
D) Yes, the only factors of the denominator of the simplified fraction are 2 or 5.

Lumber that is used to frame walls of houses is frequently sold in multiples of 2 ft. If the length of a board is not exactly a multiple of 2 ft, there is often no charge for the additional length. For example, if a board measures at least 8 ft, but less than 10 ft, then the consumer is charged for only 8 ft.
(a) Suppose that the cost of lumber is $0.70 every 2 ft. Find a formula for a function f(x)that computes the cost of a board x feet long for
\(\displaystyle{10}\leq{x}\leq{16}\)
.
(b) Determine the costs of boards with lengths of 8.6 ft and 15.1 ft.
