Final answer:
To round 582 to the nearest ten, look at the digit in the ones place, which is 2, and round down; thus 582 becomes 580.
Step-by-step explanation:
The question asks to round 582 to the nearest ten. To round a number to the nearest ten, you look at the digit in the ones place. If that digit is 5 or greater, you round up. If it is less than 5, you round down. The ones place in 582 is 2, which is less than 5, so we round down. Therefore, when you round 582 to the nearest ten, it becomes 580.
