The average newborn weighs 7.5 pounds. About 4.1 x 10^6 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
To find the approximate 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 in the U.S. per year (4.1 x 10^6 babies).
7.5 pounds/baby * 4.1 x 10^6 babies = 3.075 x 10^7 pounds
Therefore, the approximate total weight of all the babies born in the U.S in a year is 3.075 x 10^7 pounds.
