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.

Answer:
9 American dollars
Step by step:
To find the amount he will receive when he exchanges the pesos for dollars, you can use a rule of three using the information provided:
1 American Dollar is 3000/270 = 300/27 = 100/9 pesos.
270 dollars → 3,000 Mexican pesos
