Answer:
K is 3.4 feet
Step-by-step explanation:
To find the perimeter of the octagon, we add up the lengths of all the sides
For this particular octagon;
7 * k + 3.9 = 27.7
7k + 3.9 = 27.7
7k = 27.7-3.9
7k = 23.8
k = 23.8/7
k = 3.4 feet
The distance between the points is 
Step-by-step explanation:
The formula of the distance between two points
and
is 
To find the distance between two point:
- Put one of the two point as
- Put the other point as
- Substitute then in the rule of the distance and calculate the distance
∵ The two points are (18 , -2) and (6 , -10)
- Put (18 , -2) as
and (6 , -10) as
∴
= 18 and
= 6
∴
= -2 and
= -10
- Substitute them in the rule below
∵ 
∴ 
∴ 
∴ 
∵ (-12)² = 144 and (-8)² = 64
∴ 
∴ 
∵ 
∴ 
The distance between the points is

Answer:<u><em> From least to greatest, we get: 0.6010, 6.010, 6.100. Ordering these decimals from least to greatest we get: 0.601, 6.01, 6.1. Sometimes it is helpful to place a number in a circle to the right of each decimal you are trying to order.</em></u>
<u><em>Step-by-step explanation:</em></u>
We have an even list of numbers.
List from small to large.
19, 22, 22, 22, 24, 24, 26, 27, 28, 30
Add the two center numbers and divide by 2.
Let m = mean
m = (24 + 24)/2
m = 48/2
m = 24
The answer is 24.
<em>5</em>
- Step-by-step explanation:
<em>(6 + 1)² - 4 / 1 + (4² : 2) = </em>
<em>= (7² - 4) / (1 + 16 : 2)</em>
<em>= (49 - 4) / (1 + 8)</em>
<em>= 45 / 9</em>
<em>= 5</em>
