Answer 1

Answer:  6.375 feet of ribbon will be left unused.

Step-by-step explanation: Given that Ashleigh is making 9 necklaces for cody.

She has 30 feet of string to make the bows and each bow requires $2\dfrac{5}{8}$ feet of ribbon.

We are to find the length of the ribbon that will be left unused.

The length of ribbon required by one bow is $2\dfrac{5}{8}~\textup{feet}.$

So, length of ribbon required by 9 bows(necklaces) is

$2\dfrac{5}{8}\times9=\dfrac{21}{8}\times9=\dfrac{189}{8}=23.625~\textup{feet}.$

Therefore, the length of the unused ribbon is

$30-23.625=6.375~\textup{ft}.$

Thus, 6.375 feet of ribbon will be left unused.
