56,980 rounded to the nearest hundreds is 56,900.
To round the number 56,980 to the nearest hundreds, we need to look at the digit in the hundreds place, which is 9. The rule for rounding is to examine the digit to the right of the place you want to round to, in this case, the digit in the tens place. If that digit is 5 or greater, you round up; if it's less than 5, you round down.
In 56,980, the tens digit is 8, which is less than 5. Therefore, we don't need to round up. We simply drop the digits to the right of the hundreds place, which are the tens and ones digits. The hundreds digit (9) remains the same.
So, rounding 56,980 to the nearest hundreds gives us:
56,900
In this rounded number, the hundreds place (9) is unchanged, and the digits in the tens and ones places (8 and 0) have been dropped.
To understand it visually, think of 56,980 on a number line. When you round to the nearest hundreds, you're essentially finding the closest multiple of 100. In this case, 56,980 is closest to 57,000, which is why we round down to 56,900.

Answer:
Based on the data provided, Sergei can make the following predictions and set a benchmark for his performance:
Prediction 1: With consistent training and improvement over the summer, Sergei can predict that he will run the mile faster than 8:45 in his upcoming tryouts. This is based on the pattern of improvement he has shown from 9:30 (eighth grade) to 8:45 (freshman year) and his continued training.
Prediction 2: Sergei can aim to break the 8-minute mark for the mile based on the trend of his improvements. This is a reasonable goal given his past progress, and it aligns with his objective of making the varsity team where all runners need to run under 6:15.
Benchmark: The benchmark against which Sergei is measuring his performance is the time required to run a mile. He's tracking his progress in terms of how long it takes him to complete a mile, aiming to continuously improve and meet the varsity team's standard of running under 6:15 for the mile.
The required number of girls in the school assembly is 1380.
Given,
There were 1200 boys at a school assembly. The ratio of boys to girls at the assembly was 20:23. Number of girls in the assembly line is to be determined
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Representation of ratio of two values a and b, ratio = a:b.
Let the number of girls in the school assembly be x.
There were 1200 boys at a school assembly. The ratio of boys to girls at the assembly was 20:23. So the ratio can be written as,
1200 : x = 20 : 23
1200 / x = 20 / 23
x = 1200 * 23 / 20
x = 60 * 23
x = 1380
Here, the number of girls in the school assembly is 1380.
Thus the required number of girls in the school assembly is 1380.
