Describe the steps you can use to find an average of fractional amounts.

oksano4ka [1.4K]

Add up the fractional amounts and divide them by however many amounts there are..........

eg.

Step 1:Add the fractions
1/6 + 5/8 +3/4
(find the LCD)
1/6 + 5/8 + 3/4 = 4/24 + 15/24 + 18/24 = 37/24

Step 2: Divide the sum by the number of numbers in the set
37/24 ÷ 3= 37/24 ÷ 3/1= 37/24 X 1/3= 37/72

<span>So the mean (average) is 37/72</span>

Find the center and radius of the circle.<br> (x + 3)2 + (y + 4)2 =9

Tpy6a [65]

The general equation for any circle with its center at point (a, b) is

(x - a)² + (y - b)² = (radius)²

So the circle in the question is centered at (-3, -4), and its radius is 3 .

Identity the construction that the figure represents

nordsb [41]

The construction is the construction of the Perpendicular bisector.

<h3>How to illustrate the information?</h3>

The steps for the construction of perpendicular bisectors are as follows:

Open the compass more than half of the distance between A and B, and scribe arcs of the same radius centered at A and B.

Call the two points where these two arcs meet X and Y. Draw the line between X and Y.

So, the point where this line meets the line segment; M is called the mid point and the line XY is the perpendicular bisector of the line AB.

The figure is a construction of perpendicular bisector.
