Step-by-step explanation:
Zip codes with 5 digits (all five digits can be repeated): 10^5=100,000 if first digit is 0, its no longer 5-digit right? Zip codes with no digit being repeated: 10*9*8*7*6=30,240 if first digit is 0, its no longer 5-digit right? Zip codes with at least one digit being repeated: 90000-27216 = 62784 ?N

2. Therefore, you must multiply both fractions, as following:

3. Now, simplify the expression:

The answer is:
Answer:
d = 11 sqrt 41 / 2, or -11 + sqrt 41 / 2
9514 1404 393
Answer:
D. 1500
Step-by-step explanation:
7245 rounded to the nearest hundred is 7200. (Last two digits are less than 50.)
5680 rounded to the nearest hundred is 5700. (Last two digits are 50 or more, so we round up.)
Then the estimated difference is ...
7200 -5700 = 1500 . . . . matches choice D
I think it is A but make sure with someone else
