The <em>correct answer</em> is:
400 + 10 + 2 + 0.6 + 0.03 + 0.008.
Explanation:
To write a number in expanded form, we use place values.
4 is in the hundreds place; this makes its value 400.
1 is in the tens place; this makes its value 10.
2 is in the ones place; this makes its value 2.
6 is in the tenths place; this makes its value 0.6.
3 is in the hundredths place; this makes its value 0.03.
8 is in the thousandths place; this makes its value 0.008.
To write this together, we find the sum:
400 + 10 + 2 + 0.6 + 0.03 + 0.008.
6*14=84
the answer is 84cm²

Answer:
182 seconds
Step-by-step explanation:
Given:
Time taken for first lap is 50 seconds and each subsequent lap takes 20% longer than previous
Solution:
Time taken for first lap = 50 sec
For second lap
Each subsequent lap takes 20% longer than previous
Previous lap time = 50 sec
second lap = 50 + 20% of 50
second lap
second lap
second lap
For third lap
Each subsequent lap takes 20% longer than previous
Previous lap time = 60 sec
Third lap = 60 + 20% of 60
Time taken for 3 laps is equal to sum of all three laps time.
Therefore, it takes 182 seconds (3 min, 2 seconds) to run three laps
