Answer:

1)  The correct options are;

2) Yes, the quadrilateral meets the condition for the definition of a kite

Step-by-step explanation:

1) A kite has two pairs of adjacent equal sides, therefore a kite consists of two isosceles triangles adjacent to each other sharing the same base

Which shows that the diagonals which consists of the base of the two isosceles triangles and the bisector of the angles on the opposite sides of the common base of the isosceles triangles are perpendicular to each other

Therefore, the correct options are;

2) The coordinates of the given quadrilateral are;

D = (-3, 4), A = (3, 6), B = (5, 0), C = (-2, -4)

Therefore, the length of DA = √((-3 - 3)² + (4 - 6)²) = 2·√10

the length of AB = √((5 - 3)² + (0 - 6)²) = 2·√10

The length of DC = √((-3 - (-2))² + (4 - (-4))²) = √(65)

The length of CB = √((-2 - 5)² + (-4 - 0)²) = √(65)

Therefore, the figure has two pairs of congruent consecutive sides but not all four sides

The slope of the bisector CA = (6 -(-4))/(3 - (-2)) = 2

The slope of the bisector DB = (0 - 4)/(5 - (-3)) = -0.5 = -1/2

Therefore, the diagonals are perpendicular which shows that the quadrilateral meets the condition for the definition of a kite.

The answer is B i.e. one

Answer:

[tex]x = \dfrac{147}{13}[/tex]

Step-by-step explanation:

Please refer to attached for labeling of the diagram:

We have 2 triangles here in the figure:

[tex]\triangle ABC \text{ and }\triangle BDE[/tex].

1. [tex]\angle B[/tex] is common to both the triangles.

Sides AC || DE (parallel sides):

So, Corresponding angles will be equal

2. [tex]\angle A = \angle D[/tex]

3. [tex]\angle E = \angle C[/tex]

So, [tex]\triangle ABC \text{ and }\triangle BDE[/tex] are similar to each other.

Similar triangles have ratio of their sides as equal.

So, [tex]AB : BD = BC : BE[/tex]

[tex]\Rightarrow \dfrac{6+7}{6} = \dfrac{21}{21-x}\\\Rightarrow \dfrac{13}{6} = \dfrac{21}{21-x}\\\Rightarrow 13 \times (21-x) = 21 \times 6\\\Rightarrow 13x = 7 \times 21\\\Rightarrow x = \dfrac{147}{13}[/tex]

Hence, [tex]x = \dfrac{147}{13}[/tex]

Answer:

x>3

Step-by-step explanation:

2x + 10 < 5x + 1

Add -5x and -10 on both sides of the inequality.

2x + 10 -10 -5x < 5x + 1 -5x -10

2x -5x < 1 -10

Subtract like terms.

-3x < -9

Multiply -1 and reverse the inequality.

3x>9

Divide 3 into both sides of the inequality.

3x/3>9/3

x>3

Answer: x > 3

Step-by-step explanation: Put your x's together on the left side of the inequality by subtracting 5x from both sides to give you -3x + 10 < 1.

Next, put your numbers together on the right by

subtracting 10 from both sides and we have -3x < -9.

To get x by itself, divide both sides by -3, but watch out.

If you multiply or divide both sides of an inequality by a negative,

you must switch the direction of the inequality sign.

Please give this idea your full attention.

Even the most advanced algebra students will sometimes forget to

switch the direction of the inequality sign when multiplying or

dividing both sides of an inequality by a negative.

So we have x > 3 as our answer.

I have graphed the solution below.

Answer:

k = - 3

Step-by-step explanation:

Given

9kx + 12ky = 63

Since x = - 1 and y = - 1 are solutions of the equation

Substitute x = - 1 and y = - 1 into the equation and solve for k

9k(- 1) + 12k(- 1) = 63, that is

- 9k - 12k = 63

- 21k = 63 ( divide both sides by - 21 )

k = - 3

Answer:

Surface area of the given prism = 63 square feet

Step-by-step explanation:

Surface area of the given triangular prism = Area of two triangular bases + Area of three vertical rectangles

Area of triangular bases = 2[[tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]] (Since the bases of this prism are right triangles)

                                        = 3 × 3

                                        = 9 square ft

Area of one vertical rectangular face = (Length × Width)

                                                             = (3 × 6)

                                                             = 18 square feet

Area of all vertical sides = 3 × 18 = 54 square feet

Total surface area = 9 + 54 = 63 square feet

Answer:

The graph moves 4 right and 12 down.

Step-by-step explanation:

So let me rewrite the function into all variables:

y = |x + z| + a

If z goes up, the graph moves right.

If z goes down, the graph moves left.

If a goes up, the graph moves up

If a goes down, the graph moves down.

The graph moves 4 right and 12 down.

Answer:

d)25 percent

Step-by-step explanation:

5/20×100

0.25×100

25 percent

Mark brianliest if my answer suit your question.

The percentage of fruits that are apple are 25%.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Total fruits= 20

Number of apples= 5

let the percent of fruits that are apple be x.

So, x% of 20= 5

x/100 (20) = 5

x/5 = 5

x = 25%

Hence, the percentage is 25%.

Answer:

cost of journey of 25 miles =  £ 17.5

Step-by-step explanation:

Base on the equation the cost of the journey can be represented as

C = 0.5n + 5

where

C = cost in £

n = number miles covered

To calculate the cost of a journey that is 25 miles we have to insert the value of n as 25  in the equation. Therefore,

C = 0.5n + 5

n = 25

C = 0.5(25) + 5

C = 12.5 + 5

C = £ 17.5  

cost of journey of 25 miles =  £ 17.5

Answer:

95 degrees

Step-by-step explanation:

a triangle's interior angles add up to 180 add the two known angles subtract by 180 and you get the answer.

55 + 30 = 85

180 - 85 = 95

95 degrees

Answer:

C =95

Step-by-step explanation:

The sum of the angles of a triangle is equal to 180 degrees

A + B + C = 180

55 + 30 + C = 180

Combine like terms

85 + C = 180

Subtract 85 from each side

85+C - 85 = 180-85

C =95

Answer:

g = 12

Step-by-step explanation:

–19g = –20g + 12

Add 20 g to each side

–19g+20 g = –20g+ 20g + 12

g = 12

Answer:

g = 12

Step-by-step explanation:

→The first step is to add 19g to both sides:

-19g = -20g + 12

+19g   +19g

____________

0 = -g + 12

→Subtract 12 from both sides:

0 = -g + 12

-12       -12

_________

-12 = -g

→Divide both sides by -1:

12 = g

Answer:

[tex]SU = 20[/tex]

Step-by-step explanation:

Given

Triangle TSU

Bisector TX

Required

Length of SU

A line is said to be a perpendicular bisector if and only if it divides a line segment into two equal lengths;

This means that line TX divides line SU into two equal part.

This implies that

[tex]SU = SX + UX[/tex]

and

[tex]SX = UX[/tex]

Substitute [tex]SX = UX[/tex]; The expression becomes

[tex]SU = UX + UX[/tex]

Recall that [tex]UX = 10[/tex];

So, the above expression becomes

[tex]SU = 10 + 10[/tex]

[tex]SU = 20[/tex]

Hence, the length of is 20
