<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:
1/90.
Step-by-step explanation:
the pattern goes up by eight.
it would continue like so:
1/2, 1/10, 1/18, 1/26, 1/34, 1/42, 1/50, 1/58, 1/66, 1/74, 1/82, 1/90.
1/90 would be the 12th number in the sequence.
Given:
The figure shows the letter Z and four of its transformed images—A, B, C, and D.
To find:
Which of the following rules will transform the pre-image of Z in quadrant 2 into its image in quadrant 1?
Solution:
From the figure it is clear that the pre-image of Z in quadrant 2 and its image in quadrant 1 (image A) are the mirror image of each other along the y-axis.
It means the pre-image of Z in quadrant 2 reflected across the y-axis to get the image in quadrant 1.
If a figure reflected across the y-axis, then rule of transformation is
So, the rule transform the pre-image of Z in quadrant 2 into its image in quadrant 1.
Therefore, the correct option is c.
