Answer:
24,000 cm^3
Step-by-step explanation:
Volume is LxWxH
20x30x40=24,000cm^3
You use the Pythagorean theorem and square 3 and 4. You then get 9 and 16. Add both to get 25. The square root of 25 is 5 so 5 is your answer

Answer:
$27,000
Step-by-step explanation:
5.4 x 10^10 = 54,000,000,000
54,000,000,000 / 2 x 10^6 = 27,000
That is 27,000 dollars per person.
Answer:
Therefore 53.05 mg will remain of the given radioactive substance after 35 hours.
Step-by-step explanation:
Radioactive Decay:
Integrating both sides
[ ]
When t=0, = initial amount
Therefore the decay equation is
Given that, = Initial amount of the radioactive substance= 140 mg
After 25 hours, 70 mg of substance remains.
N= 70 mg, t=25 hours
[ ]
The decay equation becomes
Now putting t= 35
= 53.05 mg
Therefore 53.05 mg will remain of the given radioactive substance after 35 hours.
