Answer: 19200 years
Step-by-step explanation:
The fossil in the above question has aged for 3.3 half lives. Since the half life of a fossil is given as 5730 years, the age of the fossil will be given as:
= 5730 years × 3.3333333
= 19200 years
Therefore, the age of the fossil is 19200 years.
Answer: 6 fishes
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere = 4/3 x π x (diameter/2)^3
Replacing with the values given:
V = 4/3 x π x (20/2)^3
v = 4/3 x π x (10)^3 = 4,188.79 in3
Finally, we have to divide the volume of the fish tank by the volume that each goldfish needs.
4,188-79 / 693 = 6.04 = 6 fishes
Feel free to ask for more if needed or if you did not understand something.
