What two numbers are missing from this factor tree for the prime factorization of 189? 3*63 * 3*7 a. 2 and 5 b. 5 and 7 c. 9 and 7 d. 3 and 21

189   = 3*63

       = 3 * 7*9

       = 3 *7 * 3*3

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
