Help? I hate math but yeah

1. 45

2. 44

3. 30

4. 49.9995

5. 65

Step-by-step explanation:

1. 135 divided by 3

2. 22 times 2

3. 7.5 times 4

4. 100 over 3 would equal 33.333 miles in 2/3 of an hour, or 40 minutes. In 20 minutes you would go 16.6665 miles. 20 x 3 = 60 so 16.6665 x 3 would equal 49.9995

5. 97 1/2 divided by 3. Then multiply that number by 2

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.
