straight fans is to be constructed from posts 6 inch wide and separated by lengths of chain 5 feet long.if a certain friends begins and ends with a post, which of the following to be the length of the fence in feet? 12 inches is equal to 1 feet ​

Answer 1

Answer:

The fence begins and ends with a post: {post = 0.5 feet}{chains = 5 feet}{post = 0.5 feet}...{chains = 5 feet}{post = 0.5 feet}

The minimum length is with 2 posts = 0.5 + 5 + 0.5 = 6 feet. To increase the fence, each time we should add{post = 0.5 feet}{chains = 5 feet}, so 5.5 feet. Thus, the lengths could be:

6 feet;

6 + 5.5 = 11.5 feet;

11.5 + 5.5 = 17 feet;

17 + 5.5 = 22.5 feet;

22.5 + 5.5 = 28 feet;

28 + 5.5 = 33.5 feet;

33.5 + 5.5 = 39 feet.

...

We skipped 35 feet.
