A population of 800 cheetahs decreases by 13% per year. How many cheetahs will there be in 5 years. Round your answer to the nearest whole number.
Halp meh plz
13% decrease means that there is 87% as much each year. So, kee multiplying by 0.87
800 * 0.87^5 = ______
funny - I read it as "800 cheerleaders" at first...
lololol thats funny... Thanks for the help though!
Sure, I can help you with that!
To find the number of cheetahs in 5 years, we need to calculate the final population after 5 years of decreasing by 13% annually. Here's the step-by-step process:
Step 1: Calculate the annual decrease:
The annual decrease is given as 13% per year, which can be written as 0.13. We need to subtract this percentage from 1 to get the remaining percentage (100% - 13% = 87% or 0.87).
Step 2: Calculate the final population after 5 years:
The formula to calculate the final population is:
Final Population = Initial Population * (Annual Decrease)^Number of Years
Plugging in the given values:
Final Population = 800 * (0.87)^5
Step 3: Evaluate the equation:
Using a calculator or a software, we can directly calculate the value of (0.87)^5.
Final Population ≈ 800 * 0.4401
Step 4: Round the answer to the nearest whole number:
Final Population ≈ 352.08
Rounding to the nearest whole number, the estimated population of cheetahs after 5 years will be 352.
Therefore, there will be approximately 352 cheetahs left in the population after 5 years.
Sure, I can help you with that! To find out how many cheetahs will be left in 5 years, we need to calculate the population after each year and continue decreasing it by 13%. Here's how you can do it step by step:
1. Start with the initial population of 800 cheetahs.
2. Calculate the decrease in population by multiplying 800 by 13% (or 0.13) to find out how many cheetahs are lost in the first year. 800 * 0.13 = 104.
3. Subtract the number of cheetahs lost (104) from the initial population (800) to get the population after the first year: 800 - 104 = 696.
4. Repeat steps 2 and 3 for each subsequent year. In this case, you need to repeat it four more times for a total of five years.
5. After repeating the process for five years, you will have calculated the population after each year and obtained the following values: 696, 605, 526, 457, and 398.
6. Round the final population to the nearest whole number. In this case, the final population after five years is approximately 398 cheetahs.
Therefore, in 5 years, there will be approximately 398 cheetahs remaining in the population.
