Step-by-step explanation:

Words Decimal Representation Scientific Notation

ten million 10,000,000 1 x 107

one hundred million 100,000,000 1 x 108

one billion 1,000,000,000 1 x 109

ten billion 10,000,000,000 1 x 1010

Answer 2

1,000,000,000 1 x 109
One year = (365)x(24)x(60)x(60)
Seconds = 31,536,000 seconds= 31.536 million seconds
So 1 Billion Seconds
(1000,000,000)/31,536,000= 31.536 years
So 1 billion seconds would be 31 years 8 mouths 19 days 1 hour 46 minutes and 4 seconds
