A<em> perpendicular bisector</em> is a straight <u>line</u> drawn at an angle 90^{o} to a given line segment and <em>divides</em> the segment into two equal parts. Thus the appropriate answer to the question is option B. Definition of the <em>perpendicular</em> bisector.

A <u>bisector</u> is a line that divides a given line segment into two equal parts. It is always drawn at a <em>right angle</em> to the given line segment, thus sometimes referred to as a <em>perpendicular bisector</em>.

So in the given question, line CD divides AB into <u>two</u> equal halves and it is drawn at an angle of  90^{o}.

Such that;

<AED = <BED (<u>right </u>angle property)

Therefore, segment CD is a <em>perpendicular bisector</em> of segment AB.

Thus the required answer is option B. Definition of the <em>perpendicular bisector</em>.

Holly made 12 pair of earrings for each of her girlfriends. To wrap the pairs individually, she creates a simple cardboard gift
Mekhanik [1.2K]

Answer:

3280cm²

Step-by-step explanation:

We are told the gift box is folded into a Pyramid with a square base.

Hence, we are to find the Surface Area of a square pyramid

From the question, we are given:

Length of the base of the square = 10cm

Triangle

Side length = 10cm

Height = 8 2/3 cm

A square Pyramid has 5 faces: 4 triangles and 1 square.

Step 1

Find the Area of the square

Formula = Side length² this is because all the side of a square is equal.

Length of the base = 10cm

Area of the square = (10cm)²

= 100cm²

Step 2

Find the Area of the triangle. We are told the 4 triangles are equilateral, which means their side are equal.

Hence, for one triangle.

Area of a triangle = 1/2 × base × height

Base = side length = 10cm

Height = 8 2/3 = 8.6666666667cm

Area of a triangle = 1/2 × 10 × 8.6666666667

Area of a triangle = 43.333333333cm²

Since we have 4 triangles

We would have : 4 × 43.333333333cm²

= 173.33333333cm²

The Area of the 4 equilateral triangles =

173.33333333cm²

Step 3

The Surface area of the Square Pyramid

= Sum of the areas of all the faces.

= 100cm² + 173.33333333cm²

= 273.33333333cm²

Therefore, the minimum amount of cardboard needed to make one gift box = 273.33333333cm²

Step 4

The minimum amount of cardboard Holly needs to create 12 gift boxes to wrap each pair of earrings individually is calculated as: 12 × 273.33333333cm²

= 3280cm²
