Answer:
160%
Step-by-step explanation:
percents are out of 100
for example, 60% is 60/100
to get 8/5 as a percent, create an equivalent fraction with 100 as the denominator
8/5 is equivalent to 160/100 (both 8 and 5 were multiplied by 20)
so 8/5 is 160%
or
you could divide 5 into 8 and get 1.6 which is 160%
Answer:
8, 15, 17
Step-by-step explanation:
The 2nd option. You know this by using this math formula: a^2 + b^2 = c^2. That is the formula to find a right triangle. So if you square 8 and 15 you get 64 and 225, and if you add them together you get 289, which is 17^2. Hope this helps! :)
$2550 because 15% of 3000 is 450, so 3000 - 450 = 2550
Step-by-step explanation:
1. the number of parts that the dividend is being divided into
2. opposite operations that undo one another
3. the result of dividing two numbers
4. the number being divided
5. the quotient of any number and zero

Given:
The recursive formula of a geometric sequence is
![a_n=a_{n-1}\cdot (\dfrac{1}{8})](https://tex.z-dn.net/?f=a_n%3Da_%7Bn-1%7D%5Ccdot%20%28%5Cdfrac%7B1%7D%7B8%7D%29)
![a_1=-3](https://tex.z-dn.net/?f=a_1%3D-3)
To find:
The explicit formula of the given geometric sequence.
Solution:
We know that, first term of geometric sequence is
.
Recursive formula of a geometric sequence is
...(i)
where, r is common ratio.
We have,
...(ii)
On comparing (i) and (ii), we get
![r=\dfrac{1}{8}](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7B1%7D%7B8%7D)
The explicit formula of a geometric sequence is
![a_n=a_1r^{n-1}](https://tex.z-dn.net/?f=a_n%3Da_1r%5E%7Bn-1%7D)
Putting
and
, we get
![a_n=-3\left(\dfrac{1}{8}\right)^{n-1}](https://tex.z-dn.net/?f=a_n%3D-3%5Cleft%28%5Cdfrac%7B1%7D%7B8%7D%5Cright%29%5E%7Bn-1%7D)
Therefore, the correct option is D.
