In a study on vaccine distribution, 80% of a town's population of 10,000 are vaccinated. If 5% of vaccinated people experience mild side effects, how many vaccinated individuals experience side effects?
Number of vaccinated individuals: \( 10000 \times 0.8 = 8000 \).
Number experiencing side effects: \( 8000 \times 0.05 = 400 \).
A science journalist reports that the Earth’s average temperature has risen by 1.2°C since pre-industrial levels. If the increase is projected to be 0.2°C per decade, how many decades until the increase reaches 2°C?
Degree increase needed: \( 2°C - 1.2°C = 0.8°C \).
Number of decades: \( \frac{0.8}{0.2} = 4 \).
A technology consultant calculates that migrating to the cloud reduces operational costs by 35%. If the current annual cost is $1,200,000, what is the new annual cost?
Savings: \( 1,200,000 \times 0.35 = 420,000 \).
New cost: \( 1,200,000 - 420,000 = 780,000 \).
