Step-by-step explanation:
To find the count of the virus after 4 hours with a 20% hourly spread rate, you can use the following formula:
Count after time = Original count * (1 + Spread rate)^Number of hours
In this case, the spread rate is 20% per hour, which is equivalent to 0.2 in decimal form. The original count is 10,000, and you want to calculate the count after 4 hours:
Count after 4 hours = 10,000 * (1 + 0.2)^4
Count after 4 hours = 10,000 * (1.2)^4
Count after 4 hours ≈ 10,000 * 2.0736
Count after 4 hours ≈ 20,736
So, the count of the virus after 4 hours would be approximately 20,736.
Answer:
10000 = 100%
1000 = 10%
2000 = 20%
Step-by-step explanation:
20% virus spread in 1 hour
20% × 4 hours = count of virus spread in 4 hours
Again (2000 = 20%)
2000 × 4 = 8000
So, 8000 count of viruses spread in 4 hours
