To find the total weight of all the babies born in the U.S. in a year, we multiply the average weight of a newborn (7.5 pounds) by the number of babies born (4.1 x 10^6).
7.5 pounds * (4.1 x 10^6) = 3.075 x 10^7
Therefore, the approximate total weight in pounds of all the babies born in the U.S. in a year is 3.075 x 10^7 pounds.
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)
