Question

you designed a banner to hang at the picnic. the banner is 8 feet long. if you want to put a nail in the banner every 1/2 foot, how many nails will it take to hang the banner? type your answer here. use the table to figure out how many feet of each decoration you need to buy. orange green total ribbon 5 1/4 feet 12 2/3 feet streamers 8 2/5 feet 7 1/3 feet flags 6 8/9 feet 15 1/3 feet lights 3 1/2 feet 7 3/4 feet

Explanation:

Step1: Calculate the number of intervals

The length of the banner is \(8\) feet and the interval between nails is \(\frac{1}{2}\) foot. The number of intervals \(n\) is calculated by dividing the total length by the interval length: \(n=\frac{8}{\frac{1}{2}}=8\times2 = 16\).

Step2: Calculate the number of nails

The number of nails is one more than the number of intervals (because we need a nail at the start and end). So the number of nails \(N=n + 1\). Since \(n = 16\), then \(N=16+1=17\).

Answer:

\(17\)
