110.
All the 500s start with a 5 so that is 100 numbers that start (or end) with a 5.
Of the 400s, only those which ends with a 5 will do which are 405, 451, ..., 495. ie once for each possible tens digit; the tens digit can be one of 0, 1, ..., 9, ie one of 10 values, so there are a further 10 numbers that (start or) end with a 5.
making 100 + 10 = 110 numbers in all.
To find how many numbers between 400 and 600 begin or end with the digit 5, we can break it down. The numbers that begin with 5 in this range are from 500 to 599, totaling 100 numbers. The numbers that end with 5 are 405, 415, 425, ..., 595, which gives us 20 numbers. However, the number 505 is counted in both categories, so the total is 100 + 20 - 1 = 119. Therefore, there are 119 numbers between 400 and 600 that either begin or end with the digit 5.

A 400-digit number is typically referred to as a "400-digit number." In mathematics, numbers are categorized by their number of digits, such as single-digit numbers, double-digit numbers, triple-digit numbers, and so on. Therefore, a number with 400 digits would simply be called a "400-digit number."

The three-digit numbers between 99 and 400 start from 100 and go up to 399. To find the total count, we can calculate it as follows: 399 - 100 + 1 = 300. Therefore, there are 300 three-digit numbers between 99 and 400.

400 of them.
To find the numbers between 400 and 600 that either begin or end with the digit 5, we can break it down into two parts. First, let's find the numbers that begin with 5: There are 10 numbers between 500 and 599 that start with 5. Next, let's find the numbers that end with 5: There are 10 numbers between 405 and 595 that end with 5. Adding these two sets together gives us a total of 20 numbers between 400 and 600 that either begin or end with the digit 5.

The three-digit numbers between 99 and 400 start from 100 and go up to 399. To find the total count, we can calculate it as follows: 399 - 100 + 1 = 300. Therefore, there are 300 three-digit numbers between 99 and 400.
5*5*4*4 = 400
All of the four-digit multiples of 400 end in 00.
It is the first or leftmost digit: 4.
