Answer:
22
Step-by-step explanation:
(4 x 4) + (2 x 3) = 16 + 6 = 22
The initial term of this geometric series is 4, and the common ratio is -1/2. The sum is given by
![S_{n}=a_{1}\dfrac{r^{n}-1}{r-1}\\\\S_{10}=4\cdot \dfrac{(-\frac{1}{2})^{10}-1}{-\frac{1}{2}-1}=4\cdot \dfrac{(\frac{1}{1024}-1)}{(-\frac{3}{2})}\\\\=\dfrac{8}{3}\cdot \dfrac{1023}{1024}=\dfrac{341}{128}](https://tex.z-dn.net/?f=S_%7Bn%7D%3Da_%7B1%7D%5Cdfrac%7Br%5E%7Bn%7D-1%7D%7Br-1%7D%5C%5C%5C%5CS_%7B10%7D%3D4%5Ccdot%20%5Cdfrac%7B%28-%5Cfrac%7B1%7D%7B2%7D%29%5E%7B10%7D-1%7D%7B-%5Cfrac%7B1%7D%7B2%7D-1%7D%3D4%5Ccdot%20%5Cdfrac%7B%28%5Cfrac%7B1%7D%7B1024%7D-1%29%7D%7B%28-%5Cfrac%7B3%7D%7B2%7D%29%7D%5C%5C%5C%5C%3D%5Cdfrac%7B8%7D%7B3%7D%5Ccdot%20%5Cdfrac%7B1023%7D%7B1024%7D%3D%5Cdfrac%7B341%7D%7B128%7D)
The sum is
approximately 2.66.
The numbers would be -1, 0, 1, 2.
Hope this helps
Answer:
Would it be 70/100 as a fraction and 0.7 as a decimal and 70% as a percentage?
Step-by-step explanation:
If you have 100 squares and 70 of those squares are shaded, your answer would 70/100.
