8a-15>73

8a-15+15>73+15

Add 15 to both sides

8÷8a>88÷8

Divide both sides by 8

a>11

So you answer is B because the sign is only greater than and not and greater than equal to sign. Also remember if the sign is going > than the line goes to your right and if the sign is < than the line goes to the left of it.

Plutonium-240 decays according to the function Q(t)=Q(subscripto)e^(-kt) where Q represents the quantity remaining after t years

svetoff [14.1K]

<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>
