Answer:

Step-by-step explanation:

a).

2.2 × 10^{-3} + 9 × 10^{-4} =

2.2 × 10^{-3} + 0.9 × 10^{-3} =

( 2.2 + 0.9 ) × 10^{-3} = <em>3.1 × </em>10^{-3}

b).

2.2 × 10^{-3} - 9 × 10^{-4} =

2.2 × 10^{-3} - 0.9 × 10^{-3} =

( 2.2 - 0.9 ) × 10^{-3} = <em>1.3 × </em>10^{-3}

Anton will be constructing a segment bisector with a compass and straightedge, while Maxim will be constructing an angle bisecto
elena-14-01-66 [18.8K]

A bisector is a line that divides either a line or an angle into <em>two</em><em> proportionate</em> parts or angles. Thus, Anton's <em>bisector</em> would divide the segment into two <u>equal parts</u>, while Maxim's <em>bisector</em> would divide the angle into two <u>equal angles</u>.

The <u>similarities</u> between their construction are:

  • <em>Intersecting</em> arcs through which the bisector would pass are required.
  • The arcs are dawn using <em>the same</em> radius of any measure.
  • The <em>edges</em> of the arc of the given angle, and the ends of the segment are used as <em>centers</em>.

The <u>differences</u> between their construction are:

  • Anton has to draw two intersecting arcs <u>above</u> and <u>below</u> the segment. While Maxim would draw two intersecting arcs <u>within</u> the lines forming the angles.
  • Anton's bisector would be <em>perpendicular</em> to the segment, while Maxim's bisector would be at <em>an angle</em> which is half of the initial angle.

A regular hexagon (6-sided figure) has sides that are all the same length. Each side length is represented by the expression x +
Mandarinka [93]
Perimiter=6 times legnth of one side
P=6(x+1/3y)
P=6x+6/3y
P=6x+2y

if x=5 and y=6
P=6(5)+2(6)
P=30+12
P=42


A. P=6x+2y
B. 42 units is the perimiter
