Answer
3.027 × 10^7
I'm not the best at explaining but here is my attempt
You start with 30270000 you write the first number which is 3 then put a decimal and then put the rest of the numbers until the rest of the numbers are zeros..
3.027
Then put a × 10^
3.027 × 10^
And then the original number's digit count minus 1 is the number so 0270000 is 7 digits so the answer is
3.027 × 10^7
Sorry i'm horrible at explaining
Answer:
5.11%
Step-by-step explanation:
The formula for percent increase is given as:
% increase = Increase ÷ Original Cost × 100.
Increase = Current cost - Original cost
= $52.50 - $49.95
= $2.55
Hence,
% increase = $2.55/$49.95 × 100
5.1051051051%
Approximately , Percent Increase = 5.11%
Therefore, the percent increase of the cost of the train set is 5.11%
You would do 256.5/18 to get the other side which is 14.25, then you add 18 and 14.25 getting 32.25, now multiply that by 2 because there are 2 of each length sides, and you get 64.5 meters as the perimeter
