Agev wants to make a 6-digit pin number, using the digits, 1, 2, 3, 4, 5, and 6, once
each. he wants a way to remember the number. he decides to make a special 6-
digit number so that the first digit is divisible by 1, the first wo digits are divisible by
2, the first three digits are divisible by 3, the first four digits are divisible by 4, the
first five digits are divisible by 5, and the entire 6-digit pin number is divisible by 6.
agev find a 6-digit pin number that meets the divisibility conditions.

123654

Step-by-step explanation:

1 is divisible by 1

12 is divisible by 2

123 is divisible by 3

1236 is divisible by 4

12365 is divisible by 5

123654 is divisible by 6

hope this helped :)

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

answer: the answer is ann
