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 (4.1×10^6).
7.5 pounds x 4.1×10^6 babies = 30.15×10^6 pounds
Now, we need to express this in scientific notation.
30.15×10^6 pounds = 3.015×10^7 pounds
Therefore, the approximate total weight of all the babies born in the U.S. in a year is 3.015×10^7 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.
