Answer:
use the pythagoras theorem ok for 3rd side
i.e. (5.6)²+(3.9)²=c²
To determine the perimeter of the pentagon, you must first calculate a side length of it. Let's name the coordinates A(-1,4) and B(2,3).
To figure out how far the points are from each other, you have to use the distance formula:



D_{AB}= \sqrt{(2--1)^2+{(3-4)^2}




Now, the formula for the perimeter of a pentagon is
P = 5×side length
So...
Perimeter = 5×

The answer is (2)
Answer:
Lower (or First) Quartile = 15
Step-by-step explanation:
Answer:
The value of c from the equation is 5.
Step-by-step explanation:
c/5 - 4 = -3
Add 4 to both sides of the equation.
c/5 = 1
Multiply both sides by 5 to get c by itself.
c = 5
Answer:
14%
Step-by-step explanation:
First find the total for all the dresses.
Total = 14 + 37 + 22 + 56 + 33
Total = 162
Now you are concerned about the blue dresses.
% = (22 / 162) * 100 = 13.58 %
Rounded to the nearest % it would be 14%
The number of degrees it would occupy in the pie chart would be 360 * 14/100 = 49 degrees.
