The average newborn weighs 7.5 pounds. About 4.1×10^6 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. (hint: the answer is equal to 30750000)
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 (7.5 pounds) by the number of babies born in the U.S. every year (4.1×10^6).
The calculation is as follows:
7.5 pounds/baby * 4.1×10^6 babies = 30,750,000 pounds
To express this answer in scientific notation, we can write it as:
3.075×10^7 pounds
