Final answer:
The value of x in the ratio x:50:5 is found by simplifying the last two terms of the ratio to 10:1, indicating x should be 10 times the value associated with 5 in the ratio. Hence, x is 10 feet.
Step-by-step explanation:
To find the value of x in the ratio x:50:5, we first need to understand that the numbers in the ratio represent a relationship between quantities that can be scaled up or down while maintaining the same proportion. In this case, we need the ratio to be in the simplest form comparable to x:50:5. The given ratio of 50:5 simplifies to 10:1, meaning for every 10 units of the second term, there is 1 unit of the third term.
We can see that 50 is 10 times 5, so according to the ratio, x should also be 10 times 1 (the simplified value corresponding to 5). Therefore, x equals 10. So the correct answer would be x = 10.0 feet which matches option B.
