Answer:
C
1/2 of the circle which means half is blue!
please give brainliest!
First add 15 to both sides:
2n = 68
Then divide each side by two.
n = 34
Answer:
N1,052,800.
Step-by-step explanation:
The starting salary of the officer = N57,000
Increase per annum =N2,800
The given pattern forms an arithmetic sequence since the annual salary increases by a fixed amount.
We are to determine the total amount of money that the officer will earn in 14 years.
Sum of an arithmetic sequence, ![S_n=\frac{n}{2}[2a+(n-1)d]$ ,where: \left\{\begin{array}{lll}$First term, a=57,000\\$Common difference, d=2,800\\$Number of terms, n=14\end{array}\right](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D%24%20%2Cwhere%3A%20%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Blll%7D%24First%20term%2C%20a%3D57%2C000%5C%5C%24Common%20difference%2C%20d%3D2%2C800%5C%5C%24Number%20of%20terms%2C%20n%3D14%5Cend%7Barray%7D%5Cright)
![S_{14}=\frac{14}{2}[2(57,000)+(14-1)(2,800)]\\=7[114,000+13*2800]\\=7[150,400]\\=1,052,800](https://tex.z-dn.net/?f=S_%7B14%7D%3D%5Cfrac%7B14%7D%7B2%7D%5B2%2857%2C000%29%2B%2814-1%29%282%2C800%29%5D%5C%5C%3D7%5B114%2C000%2B13%2A2800%5D%5C%5C%3D7%5B150%2C400%5D%5C%5C%3D1%2C052%2C800)
At the end of 14 years, the total amount earned by the officer will be N1,052,800.
I’m not sure this is right or not but, I think the answer is A
We can find the area of each shape separately
The area of the triangle can be found by A = 1/2bh
So the area will be 1/2 times (6+14+6= 26) 26 times 21
The area of the triangle will be 273 ft^2
The area of the square will be A=lxh
So the area will be 14 times 14
So the area of the square will be 196 ft ^2
We then add the area of both shapes together to get the total area
273 + 196 = 469 ft^2
