Answer:
Colin will have 421824 pennies after 2 years
Step-by-step explanation:
Given:
Amount invested in bank by Colin (P) = £3900
Rate of interest (r) = 4%
Time period (n) = 2 years
To find: Amount after 2 years (A)
Solution:
Formula for amount (A) is ![A=P\left ( 1+\frac{r}{100} \right )^n](https://tex.z-dn.net/?f=A%3DP%5Cleft%20%28%201%2B%5Cfrac%7Br%7D%7B100%7D%20%5Cright%20%29%5En)
![A=3900\left ( 1+\frac{4}{100} \right )^2\\=3900\left ( 1+\frac{1}{25} \right )^2\\=3900\times \frac{26}{25}\times \frac{26}{25}\\=4218.24](https://tex.z-dn.net/?f=A%3D3900%5Cleft%20%28%201%2B%5Cfrac%7B4%7D%7B100%7D%20%5Cright%20%29%5E2%5C%5C%3D3900%5Cleft%20%28%201%2B%5Cfrac%7B1%7D%7B25%7D%20%5Cright%20%29%5E2%5C%5C%3D3900%5Ctimes%20%5Cfrac%7B26%7D%7B25%7D%5Ctimes%20%5Cfrac%7B26%7D%7B25%7D%5C%5C%3D4218.24)
As 1 pound = 100 pennies,
4218.24 pounds = 4218.24 × 100 = 421824 pennies
So,
Colin will have 421824 pennies after 2 years.
It would be: 2 / 5/8
We can re-write it as: 2 * 8/5 = 16/5
So, your final is 16/5 or 3.2

Step-by-step explanation:
The surface area is the lateral area plus the base area. The base area is 9*5=45. Since there are two bases, its 90. Subtract that from 286 to get the lateral surface area, which is 196. The lateral surface area is the base perimeter*height. The base perimeter is 9+9+5+5= 28. 196/28=height. The height is 7
