900
You work backwards;
Since he read 3/4 of the remainder that would be 75 x 4 because 75 was left after 3/4. You would get 300. Then, you would do 300 / (1/3), this is getting the final thing, equals 900.
Hope this helps!
We can calculate the age by using the formula: final amount=initial amount*(1/2)^(time/half-life), or t=ln(final amount/initial amount)/(-0.693)*half-life. The half life of C-14 is 5730 years, and final amount=initial amount is 71% or 0.71, so t=ln(0.71)/(-0.693)*5730=2832 years approximately.
Answer:$73947.52
Step-by-step explanation:
The investment decreases in value, so the common ratio r is (1.000-0.012), or 0.988. Thus, A = $100,000* (0.988) ^25 = $73947.52 is the current value, after 25 years.
The answer is A. y ≤ 1-3x
Answer:
