A weight lifter can bench press 189 kg. How many milligrams (mg) is this?
Answer: We know that:

We are given, that a weight lifter can bench press 189 kg
Therefore, a weight lifter can bench press:



Therefore,
is equal to the 
The probability of landing on a shaded sector is 2/5.
Answer:
464.1
Step-by-step explanation:
5.1 * 91 = 464.1
The bicyclist travels 90 miles in 5 hours
90÷18=5
Write i in trigonometric form. Since |i| = 1 and arg(i) = π/2, we have
i = exp(i π/2) = cos(π/2) + i sin(π/2)
By DeMoivre's theorem,
i² = exp(i π/2)² = exp(i π) = cos(π) + i sin(π)
and it follows that i² = -1 since cos(π) = -1 and sin(π) = 0.
