<span>The half life of carbon 14 is 5,730 years. Round your answer to the nearest thousand
Answer - 6,000 years </span>
3x+50=6x-10
subtract 3x
50=3x-10
add 10
60=3x
divide by 3
20=x
2,3 I think that’s the answer
Answer:
165 liters of 15% solution
Step-by-step explanation:
15F + 65S = 60(1650)
F + S = 1650
F = 1650-S
15(1650-S) +65S = 99000
50S = 99000-24750= 74250
S = 74250/50 = 7425/5 = 1485 liters of 65% solution
F = 1650-1485 = 165 liters of 15% solution
65 is much closer to 60 than 15 is, so you know there will be mostly 65% solution with relatively little 15%
Hope this helps, have a nice day/night! :D
