Answer:
1. 52 degrees 2. D
Step-by-step explanation:
1. The interior angles of a triangle add up to 180, so you can do 180 - 36 - 92 to find the third angle.
180 - 36 - 92 = 52 degrees
2. the angle XYZ has to equal the sum of the angles WXY and XWY. This means that 115 = 45 + XWY
115 - 45 = 72
XWY = D. 70 degrees
<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>
