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)
_ pounds
To find the approximate total weight 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.
Average weight per baby = 7.5 pounds
Number of babies born = 4.1 × 10^(6)
Approximate total weight = Average weight per baby × Number of babies born
Approximate total weight = 7.5 pounds × 4.1 × 10^(6) babies
To write this answer in scientific notation, we need to express the number 7.5 × 4.1 as a number between 1 and 10 and multiply it by 10 raised to the appropriate power.
The product of 7.5 and 4.1 is approximately 30.75.
So, the approximate total weight of all the babies born in the U.S. in a year is 30.75 × 10^(6) pounds.
Therefore, the answer in scientific notation, expressed to the exact decimal place, is:
3.075 × 10^(7) pounds
