What is the common ratio of the geometric sequence below?

Vadim26 [7]

Answer:

$\textbf{Option C - $0.1$}\\$

Step-by-step explanation:

$\textup{A geometric series is given by}\\$ a, ar, ar^2, ar^3,. . . , ar^{n-1}, ar^n $ \\\textup{\textbf{Geometric progression or GP is a sequence of numbers in which the next number in the sequence is obtained by multiplying a number to the previous number in the sequence.}}\\$

$\textup{This number is constant through out the sequence and is denoted by $r$. it is given by $r = \frac{ar^n}{ar^{n-1}}$} \\$

$\textup{Here, the given sequence is: $70, 7, 0.7,...$}\\$

$$i.e., a = 70, ar = 7$\\$

$\textup{Hence, $r = \frac{ar}{a} = \frac{7}{70}$ }\\$

$= \frac{1}{10} = 0.1$

Each side of a hexagon is 10 inches longer than the previous side. what is the length of the shortest side of this hexagon if it

MrRa [10]

The length of the shortest side of the hexagon is; 41.833 inches

<h3>How to find the perimeter of a Polygon?</h3>

Let the length of the shortest side of the hexagon be x. Now, a hexagon has six sides and if the next side is 10 inches longer than the previous side, then the length of the six sides are;

x, x + 10, x + 20, x + 30, x + 40, x + 50

Perimeter is given as 401 inches. Thus;

x + x + 10 + x + 20 + x + 30 + x + 40 + x + 50 = 401

6x + 150 = 401

6x = 401 - 150

6x = 251

x = 251/6

x = 41.833 inches
