Answer:
Option B is correct.
The estimated perimeter of an ellipse is 37.3ft
Step-by-step explanation:
<u>Given:</u>
Length of Major-axis (2a)=15ft
Length of minor-axis (2b)=7.5ft
For an ellipse, the perimeter (P) approximately given by:
, where a and b are semi major axis and semi minor axis respectively.(Use approx. value of
)
Here, a=7.5ft and b=3.75ft, putting in above equation, we get




After solving the square-root we get,

.
Therefore, the estimated perimeter of an ellipse is 37.3ft.

Answer:
The wife gets £468 over the son
Step-by-step explanation:
Firstly, we shall calculate the total amount Brian made from from what he and Paul won.
The ratio is 1:4, meaning for every 2 part Brain takes, Paul takes 4
Paul’s share is thus 1/5 * 7800 = 7800/5 = £1560
Now we have another ratio for sharing the amount Brain has at home.
The total ratio here is 1+6+3 = 10
The share of the wife will be 6/10 * 1560 = 6 * 156 = 936
The son share is half of this which is 936/2 = 468
The difference between their shares is £936-£468 = £468
