Question

the average newborn weighs 7.5 pounds. about 4.1 X 10^6 babies are born in the US every year. what is the approximate total.weight in pounds of all the babies born in tbe us in a year

Answer 1

To find the approximate total weight of all the babies born in the US in a year, you can multiply the average weight of a newborn by the total number of babies born.

Given:
- Average weight of a newborn = 7.5 pounds
- Number of babies born = \( 4.1 \times 10^6 \)

Now, calculating the total weight:

\[
\text{Total weight} = \text{Average weight} \times \text{Number of babies}
\]

\[
\text{Total weight} = 7.5 \, \text{pounds} \times 4.1 \times 10^6
\]

Now we perform the multiplication:

\[
Total weight = 7.5 \times 4.1 \approx 30.75
\]
\[
Total weight \approx 30.75 \times 10^6 \text{ pounds}
\]

Therefore, the approximate total weight in pounds of all the babies born in the US in a year is:

\[
\approx 30.75 \times 10^6 \text{ pounds}
\]

Or, in a more reader-friendly form, approximately:

\[
30,750,000 \text{ pounds}
\]
