100 factorial is 1*2*3*......*100
Number of multiples of 2 less than 100 = 49
Number of multiples of 3 less than 100 = 33
We are double counting those that are multiples of 2 and 3 (or 6)
Number of multiples of 6 less than 100 = 16
49+33-16 =66
There are 66 factors that are multiples or 2 or 3
Answer:
x = 2.13 × 10^11
Approximately 2.13 × 10^11 mails were processed in 2006
Completed question;
There were approximately 1.6 * 10^11 pieces of mall processed by the United States Postal
Service in 2012. This is about 75% of the number of pieces of mail processed in 2006.
Approximately how many pieces of mail were processed by the United States Postal Service in
2006
Step-by-step explanation:
Let x represent the number of mails processed in year 2006
Given;
Number of mails processed in 2012 N = 1.6 × 10^11
Number of mails processed in 2012 N is about 75% of the number of pieces of mail processed in 2006.
So;
N = 75% of x
N = 0.75x
x = N/0.75
x = (1.6 × 10^11)/0.75
x = 2.13 × 10^11
Approximately 2.13 × 10^11 mails were processed in 2006
26500 + 725 = 27225
27225 x 0.06 = 1633.5
27225 + 1633.50 = 28858.50 + 50 = 28908.50 total cost
Answer:
6.7-(-2.5)=9.2 6.7+(-2.5)=4.2 Neither
2.5 + 6.7 6.7 - 2.5 2.5 - 6.7
-2.5 + 6.7 -2.5 - 6.7
-6.7 + 2.5
I think it might be A and C
