The answers are A, C, D, and E.
Step-by-step explanation:
I just multiplied 45 by how many hours and if the answer was the miles it was correct.
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
Answer:
S={1, 1, 2, 2, 3, 4}
Probability of spinning a 1 = 1 in 3 or 33%
Step-by-step explanation:
The sample space is the set of all possible outcomes in an experiment. The outcomes here are the numbers in each section of the spinner: 1, 1, 2, 2, 3, 4. The sample space is:
S={1, 1, 2, 2, 3, 4}
Two out of six possible outcomes are "1s", therefore the probability of spinnin a 1 is:
![P(1)=\frac{2}{6}=\frac{1}{3}=33.33\%](https://tex.z-dn.net/?f=P%281%29%3D%5Cfrac%7B2%7D%7B6%7D%3D%5Cfrac%7B1%7D%7B3%7D%3D33.33%5C%25)
The probability of spinning a 1 is 1 in 3 or 33%.

Answer:
c) 676 sq. ft.
Step-by-step explanation:
With the 24 ft barn, the total perimeter can be 24+80 = 104 feet. This allows the farmer to make a square pen 104/4 = 26 feet on a side, for an area of ...
(26 ft)² = 676 ft²

<em>Comment on "fence" problems</em>
These fence problems have different solutions for different ratios of "barn" length to "fence" length. When the barn length is more than 1/2 the length of the fence, the optimum shape is a rectangle in which half the fence is used parallel to the barn. (The full length of the barn is not used.)
When the barn length is between 1/2 and 1/3 the fence length, the optimum shape is a rectangle with one side equal to the barn length.
When the barn length is less than 1/3 the fence length, as here, the optimum shape is a square, with the barn side being augmented by fence as required. Here, 2 ft of fence is added to the 24 ft barn to make a square 26 ft on each side.
