To find the missing number, we need to subtract 28,542 from 70,789. The difference is 42,247, which is the missing number that completes the sentence.

Based on the information given, the person slept for 6 hours last night and woke up at 5:45 am today. To determine the time they slept, we need to subtract 6 hours from the time they woke up. By doing so, we get the time of 11:45 pm as the time they went to sleep.

Billy sold 4,034 cakes on Sunday and 1,429 cakes on Monday. To find out how many more cakes he sold on Sunday than Monday, we need to subtract the number of cakes sold on Monday from the number of cakes sold on Sunday. Therefore, the difference is 4,034 - 1,429 = 2,605 cakes.

Since Douglas gave away 8,107 toys during the party, and there were 3,297 toys left, we can calculate the total number of toys at first by adding the toys given away and the toys left. Therefore, the total number of toys at first was 8,107 + 3,297 = 11,404 toys.

The pattern is a simple arithmetic sequence where each number is decreased by 2898 from the preceding number. By following this rule, the missing numbers at the beginning and end of the sequence can be found.

The perimeter is a fundamental concept in geometry that measures the total length of the boundary of a two-dimensional shape. It is calculated by adding up the lengths of all the sides of the shape. Understanding perimeter is essential for various real-world applications, such as measuring the length of fences, calculating the amount of material needed for a border, or determining the distance around a playground.

To maximize the difference, we want the largest possible number and the smallest possible number.

Largest number: Arrange the digits in descending order: 97652

Smallest number: Arrange the digits in ascending order: 25679

Now, subtract the smaller number from the larger number:

97652 - 25679 = 71973

The difference is 71973.
