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.

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.
