To find the total weight of all the babies born in the U.S. in a year, we need to multiply the average weight of a newborn by the number of babies born.
Average weight of a newborn = 7.5 pounds
Number of babies born = 4.1 × 10^6
Total weight = Average weight × Number of babies
Total weight = 7.5 pounds × 4.1 × 10^6 babies
To multiply these numbers, we multiply the average weight by the coefficient of the number of babies and then add the exponents:
Total weight = 7.5 × 4.1 × 10^6 pounds
Total weight = 30.75 × 10^6 pounds
In scientific notation, with the coefficient expressed to one decimal place, the approximate total weight of all the babies born in the U.S. in a year is 3.1 × 10^7 pounds.
Average weight of a newborn = 7.5 pounds
Number of babies born = 4.1 × 10^6
Total weight = Average weight × Number of babies
Total weight = 7.5 pounds × 4.1 × 10^6 babies
To multiply these numbers, we multiply the average weight by the coefficient of the number of babies and then add the exponents:
Total weight = 7.5 × 4.1 × 10^6 pounds
Total weight = 30.75 × 10^6 pounds
In scientific notation, with the coefficient expressed to one decimal place, the approximate total weight of all the babies born in the U.S. in a year is 3.1 × 10^7 pounds.
