To write the numbers from 1 to 20, we need to count the digits used for each range. The numbers 1 to 9 use 1 digit each, totaling 9 digits. The numbers 10 to 20 use 2 digits each, totaling 22 digits (11 numbers). Therefore, the total number of digits required to write all the numbers from 1 to 20 is 9 + 22 = 31 digits.
1, 4, 9, 16, 25, 36
(1 + 8)*sqrt(4*9) = 9*sqrt(36) = 9*6 = 54
9,000,000,0
1 way: 96 and 2148/537

A spinner has the numbers 1 thru 9. What is the probability of P(less than 6)? Write the answer as a decimal.
1, 4, 9, 16, 25, 36
(1 + 8)*sqrt(4*9) = 9*sqrt(36) = 9*6 = 54
9 and 18

Well, as they are NUMBERS, not words, you write them the EXACT SAME WAY. So, it'd be: 1 2 3 4 5 6 7 8 9 0
