The U.S. national debt was \$ 2.9617 * 10 ^ 13 in 2021 and \$ 3.98 * 10 ^ 11 in 1971. Find how much the debt increased in the 50-year period. (1 point)
\$ 1.0183 * 10 ^ 24
\$ 3.0015 * 10 ^ 13
\$ 2.9219 * 10 ^ 11
\$ 2.9219 * 10 ^ 13
To find the increase in the national debt over 50 years, we subtract the debt in 1971 from the debt in 2021:
\$ 2.9617 * 10 ^ 13 - \$ 3.98 * 10 ^ 11 = \$ (29.617 - 0.398) * 10 ^ 12 = \$ 29.219 * 10 ^ 12 = \$ 2.9219 * 10 ^ 13
Therefore, the increase in the debt over the 50-year period is \$ 2.9219 * 10 ^ 13.
To find the increase in the U.S. national debt over the 50-year period, we need to calculate the difference between the debt in 2021 (\$ 2.9617 * 10^13) and the debt in 1971 (\$ 3.98 * 10^11).
The increase in the debt would be:
(\$ 2.9617 * 10^13) - (\$ 3.98 * 10^11) = \$ (2.9617 * 10^13 - 3.98 * 10^11)
To subtract the numbers in scientific notation, we need to make sure the exponents are the same. Since the exponents in this case are already the same (13 and 11), we can directly subtract the coefficients:
2.9617 - 3.98 = -1.0183
The resulting coefficient is -1.0183, and since we subtracted the smaller number from the larger number, the increase in debt is positive. Therefore, the correct answer is \$ 1.0183 * 10^12, or in scientific notation, \$ 1.0183 * 10^12.
To find the increase in the U.S. national debt over the 50-year period from 1971 to 2021, we need to subtract the 1971 debt from the 2021 debt.
The 2021 debt is \$ 2.9617 * 10 ^ 13, and the 1971 debt is \$ 3.98 * 10 ^ 11.
Subtracting the 1971 debt from the 2021 debt:
(\$ 2.9617 * 10 ^ 13) - (\$ 3.98 * 10 ^ 11) = \$ 2.9219 * 10 ^ 13
Therefore, the U.S. national debt increased by \$ 2.9219 * 10 ^ 13 over the 50-year period.
The correct answer is \$ 2.9219 * 10 ^ 13.
