Well... Can you tell me how many planes he has?
Also... Can you multiply the number of planes by 3?
U can refer to the picture that I’ve attach below
A yard is equal to 3 feet. So knowing this we multiply 5280 which is how many feet are in a mile by 2.5 that is the miles we will take into consideration.
5280 x 2.5= 13,200
Now this value we divide it by 3 which is how long a yard is in terms of ft measurement.
Given:
Number of boys = 5
Number of girls = 4
To find:
The number of ways in which 5 boys and 4 girls be arranged on a bench if there are no restrictions.
Solution:
We have, 5 boys and 4 girls.
Total number of boys and girls:
![5+4=9](https://tex.z-dn.net/?f=5%2B4%3D9)
If there are no restrictions, then the total number of ways to arrange 9 persons is:
![^9P_9=\dfrac{9!}{(9-9)!}](https://tex.z-dn.net/?f=%5E9P_9%3D%5Cdfrac%7B9%21%7D%7B%289-9%29%21%7D)
![^9P_9=\dfrac{9!}{0!}](https://tex.z-dn.net/?f=%5E9P_9%3D%5Cdfrac%7B9%21%7D%7B0%21%7D)
![^9P_9=\dfrac{9\times 8\times 7\times 6\times 5\times 4\times 3\times 2\times 1}{1}](https://tex.z-dn.net/?f=%5E9P_9%3D%5Cdfrac%7B9%5Ctimes%208%5Ctimes%207%5Ctimes%206%5Ctimes%205%5Ctimes%204%5Ctimes%203%5Ctimes%202%5Ctimes%201%7D%7B1%7D)
![^9P_9=362880](https://tex.z-dn.net/?f=%5E9P_9%3D362880)
Therefore, the total number of ways to arrange 5 boys and 4 girls is 9! or 362880.
Answer:
A=6143.54( to the nearest dollar A=6144)
Step-by-step explanation:
A=Pe^(r(t))
P=3100 r=0.036 t=19
A=3100e^0.036(19)
A=3100e^(0.684)
