If you divide each number by the previous one, you get:
-86 / -172 = 1/2
-43 / -86 = 1/2
-21.5 / -43 = 1/2
The common ratio is 1/2 = 0.5
Answer: the last one!! 
Step-by-step explanation:
When there is a line under it means no more than!
Hi Sebastian0113,
Your Question:
5.708 x 10^-8 in standard form
Solution:
Decimal Form:
To solve this equation just divide 5.708 by 10 8 times.
= 5.708 / 10 / 10 / 10 / 10 / 10 / 10 / 10 / 10
= 0.000000005708
5.708 x 10^-8 = 0.000000005708
Standard Form:
5.708 x 10^8
5.708 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10
= 570,800,000
Answer:
Standard Form - 570,800,000
Decimal Form - 0.0000005708
Answer: 3
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. Find the prime factorization of 27:
or 
2. The index of the radical is 3, therefore, you have rewrite it as following:
![\sqrt[3]{27}=\sqrt[3]{3^{3}}=3^{\frac{3}{3}}=3^{1}=3](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27%7D%3D%5Csqrt%5B3%5D%7B3%5E%7B3%7D%7D%3D3%5E%7B%5Cfrac%7B3%7D%7B3%7D%7D%3D3%5E%7B1%7D%3D3)
3. Therefore, as you can see, the answer is 3.
Answer:
Area=11,309.73
Step-by-step explanation:
area of a circle is πr^2 so half of the diameter is the radius so it's 60.
pi x 60^2= 11,309.73
