The approximate total weight in pounds of all the babies born in the U.S. in a year can be calculated by multiplying 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 = 7.5 pounds/baby * 4.1×10^6 babies
Multiplying these numbers, we get 3.075×10^7.
The average newborn weighs 7.5 pounds. About 4.1×106 babies are born in the United States every year. What is the approximate total weight in pounds of all the babies born in the U.S. in a year? Write the answer in scientific notation, expressed to the exact decimal place.(1 point)
