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.(1 point)
To find the approximate total weight in pounds of all the babies born in the U.S. in a year, we can multiply the average weight of a newborn by the number of babies born in the U.S. every year.
Average weight of a newborn = 7.5 pounds
Number of babies born in the U.S. every year = 4.1×10^6
Approximate total weight = 7.5 pounds × 4.1×10^6
To multiply the numbers in scientific notation, we need to multiply the coefficients (7.5 × 4.1) and add the exponents (10^0 + 10^6).
Approximate total weight = 30.75 × 10^6 pounds
Therefore, the approximate total weight of all the babies born in the U.S. in a year is 30.75 × 10^6 pounds, expressed in scientific notation to the exact decimal place.
