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 51% or 0.51, so t=ln(0.51)/(-0.693)*5730=5567 years approximately.
Part A is incorrect because for negative numbers, the greater the magnitude the smaller the number. -2 is smaller than -1, for example, and -20 is smaller than -15.
An elevation of -15ft means 15 ft below sea level, an elevation of -20ft means 20 ft below sea level, and an elevation of (+) 7ft means 7 ft above sea level.
If John started the trail at sea level (0ft elevation), then the greatest change in elevation would be between that and the second rest stop. Take the absolute value of all the numbers and see which one is the largest.
The answer to this question is -3 + 8
Answer:
46 with a remainder of .5
Answer:
No, It is not true
Step-by-step explanation:
First of all, we should have a number in the tenths place, and we don't.
Also, in the hundredths place, we should have 9, not 4.
And finally, the answers should be 0.195, not 0.042.
