Answer:
Time taken = 9987.38 years
Step-by-step explanation:
We have plutonium-240 decays according to the parent function
k is the decay constant,0.00011
k = 0.00011
We need to find how long will it take 27 grams of plutonium-240 to decay to 9 grams.
Q(t) = 9 g
Q₀ = 27 g
Substituting
Time taken = 9987.38 years
C) $2.39

Answer:
20x - 8
Step-by-step explanation:
Since we have the length and height of the rectangle we just multiply each by 2. This is because the length is the same on both sides and the height is too. The equation would look like this:
(5x-4 + 5x -4) + (5x +5x) = 10x -8 + 10 x = 20x -8
