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 total number of babies born.
Total weight = Average weight per baby * Total number of babies
Total weight = 7.5 pounds * 4.1 * 10^6 babies
To multiply these numbers in scientific notation, we multiply the average weights and add the exponents:
Total weight = 7.5 * 4.1 * 10^6 pounds
Multiplying the average weights gives us 30.75 and the exponent of 10 is 6.
Therefore, the approximate total weight of all the babies born in the U.S. in a year is 30.75 * 10^6 pounds.
Total weight = Average weight per baby * Total number of babies
Total weight = 7.5 pounds * 4.1 * 10^6 babies

Apologies for the error.
To find the total weight of all the babies born in the U.S. in a year, we multiply the average weight of a newborn by the number of babies born.
Average weight of a newborn = 7.5 pounds
Number of babies born in the U.S. every year = 4.1 * 10^6 (4.1 million)
Total weight of all babies born in the U.S. = average weight * number of babies
Total weight = 7.5 pounds * (4.1 * 10^6 babies)
Multiplying the average weight by the number of babies gives us:
Total weight = 7.5 * 4.1 * 10^6 pounds
Simplifying the multiplication:
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.

I apologize for the mistake. Let's correct the calculation.
To find the total weight, we multiply the average weight of a newborn by the number of babies born:
Average weight of a newborn = 7.5 pounds
Number of babies born in the U.S. every year = 4.1 * 10^6 (4.1 million)
Total weight of all babies born in the U.S. = average weight * number of babies
Total weight = 7.5 pounds * (4.1 * 10^6 babies)
To multiply the numbers in scientific notation, we multiply the coefficients and add the exponents:
Total weight = 7.5 * 4.1 * 10^(6+0) pounds
Calculating the numerical value:
Total weight = 30.75 * 10^6 pounds
Expressing the answer in scientific notation:
Total weight = 3.075 * 10^7 pounds
Therefore, the approximate total weight of all the babies born in the U.S. in a year is 3.075 * 10^7 pounds.

Average weight of a newborn = 7.5 pounds
Number of babies born in the U.S. every year = 4.1 * 10^6 (4.1 million)
Total weight of all babies born in the U.S. = average weight * number of babies
Total weight = 7.5 pounds * (4.1 * 10^6 babies)
To multiply the numbers in scientific notation, we multiply the coefficients and add the exponents:
