Answer:
79
Step-by-step explanation:
There is a cool easy way to solve this kind of problem. If a range is given, and the entire range increases in incrememnts of 1, then you can find the number intergers inclusive by taking the first number and subtracting it from the last and adding 1. Since in this problem you want it exclusive, we can rewrite the range to 21-99.
99-21 +1 = 78 + 1 = 79
The operation is known as rounding of a number.
This means basically if i measure the temperature of a city and it comes out to be 22.9 degrees. I will round it of to 30 degrees or the amount of significant figures i am designated with.
Similarly if its 22.85 and i have to round of to 3 significant figures it becomes 22.9 degrees.
ROunding off is obviously done watching to which digit we have to.
The answer is A. hope it helped you out
Hello,
A real-life situation would be:
In a classroom, there are 23 students. All those students are to be divided into 4 total groups. But, in the end, there will be 3 students left over (the remainder) because they are missing 1 more person to make a group of 4.
Hope this helps!
