<h3>
Answer: Choice D) 281.25 mg</h3>
================================================
Work Shown:
Plug in t = 2 and we get the following
The answer is choice D. There are 281.25 mg of aspirin in the bloodstream after 2 hours.
-----------------
Side notes:
- The 500 represents the initial amount of aspirin (in mg) in the bloodstream. This is the amount when t = 0.
- The 3/4 converts to 0.75; when solving 1+r = 0.75, we get r = -0.25, and this shows a 25% reduction in aspirin each time t goes up by 1. Every hour, the amount of aspirin in the bloodstream reduces by 25%

Answer:
50
Step-by-step explanation:
since all angles add up to 180
and since this is a right triangle the square in the corner is 90 degrees
so 40+90+x=180
130+x=180
subtract 130 from both sides
130-130+x=180-130
x=50
