Step-by-step explanation:
What is 40% of 400?
- Convert the problem to an equation using the percentage formula: P% * X = Y
- P is 40%, X is 400, so the equation is 40% * 400 = Y
- Convert 40% to a decimal by removing the percent sign and dividing by 100:40/100 = 0.4
- Substitute 0.10 for 10% in the equation: 40% * 400 = Y becomes 0.4 * 400 = Y
- Do the math: 0.4 * 400 = 160
- Y = 160
- So 10% of 150 is 160
- Double check your answer with the original question: What is 40% of 400? Multiply 0.4 * 400 = 160
Answer:
680 Bacteria
Step-by-step explanation:
378 is evenly divisible by 126, which is equal to 3.
The first 126 minutes, the 85 bacteria will double to 170 bacteria.
The second 126 minutes (252 minutes total), the 170 bacteria will double to 340 bacteria.
The final 126 minutes (378 minutes total), the 340 bacteria will double to 680 bacteria total.
