8.530 rounded to the nearest tenth degree = 8.5

Yes

To round a number to the nearest tenth, you examine the digit to the right of the tenths place. If that digit is less than 5, you round down. If it's 5 or greater, you round up.

In this case, 8.530 has a digit in the thousandths place (the 0 after the tenths place). Since this digit is 0, which is less than 5, we round down.

So, 8.530 rounded to the nearest tenth is 8.5.
