Answer:
The answer is 6.
Step-by-step explanation:
In order to determine the answer, we have to know about notation numbers. In any number, every digit has a notation, depending on its position.
I have attached an image that shows some notation numbers.
We can see that the nearest tenth position corresponds to the first decimal digit, to the right of the decimal point.
To round the number, first we have to see where is the position where we want to cut the number. Then we have to see the number to the right of the cut position. The rule says:
- If the number is equal or greater than 5, so the number to the left of the cut position will be increase one digit.
- If the number is lesser than 5, so the number to the left of the cut position will not change.
In this case, the number to the right of the cut position is 8, so we have to increase the number to the left of the cut position, 9, in one digit.
Finally, the number 5.9876 rounded to the nearest tenth is 6.

The standard quantity of metal per ring is 0.57 kilograms.
Step-by-step explanation:
Each ring requires 0.52 kilograms of a special metal.
The allowance for waste is 0.03 kilograms per ring, while the allowance for rejects is 0.02 kilograms per ring.
So, the standard quantity of metal per ring = 0.52 kg of metal required + 0.03 kg of allowance for waste + 0.02 kg of allowance for rejects)
= kilograms.
Hence, the standard quantity of metal per ring is 0.57 kilograms.
