<span>The answer is 9,990 years. Using the exponential decay question, we can figure out how long it will take Plutonium-240 to decay from 27 grams to 9 grams. Setting the equation up looks like this, 9 = 27 e^ (-0.00011 t). From this you get, 0.333333 = e ^(-0.00011 t). Next, you simplify by dividing both sides by the natural log, -1.0986 = -0.00011 t. Finally, you solve by dividing both sides by -0.00011, giving 9,987 years for t, rounded up to 9,990 years.</span>
Answer:
n-1
Step-by-step explanation:
Consecutive means that they have a difference of one, so the expression will be n-1.

Answer:
-1.17 volts
Step-by-step explanation:
The difference between "a" and "b" generally means "a-b". Here, the difference between the potentials is ...
-0.41 V - 0.76 V = -1.17 V
_____
Sometimes, when we talk about the difference, we mean the positive difference. If that is what is intended here, it is 1.17 volts.
