Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

A parallelogram is a quadrilateral (has 4 sides and 4 angle) with two pair of parallel and opposite sides. Opposite sides of a parallelogram are parallel and equal.

Given parallelogram ABCD:

AB = CD = 18 cm; BC = AD = 8 cm

∠P = ∠P, ∠PDA = ∠PCQ (corresponding angles are equal).

Hence ΔPCQ and ΔPDA are similar by angle-angle similarity theorem. For similar triangles, the ratio of their corresponding sides equal. Therefore:

[tex]\frac{CD}{PC}= \frac{AD}{CQ}\\\\\frac{18}{6}=\frac{8}{x} \\\\x=\frac{6*8}{18}=\frac{8}{3}\ cm[/tex]

Perimeter of CPQ = CP + CQ + PQ

15 = 6 + 8/3 + PQ

PQ = 15 - (6 + 8/3)

PQ = 6.33

∠CQP = ∠AQB (vertical angles), ∠QCP = ∠QBA (alternate angles are equal).

Hence ΔCPQ and ΔABQ are similar by angle-angle similarity theorem

[tex]\frac{AQ}{QP}=\frac{AB}{CP} \\\\\frac{AQ}{6.33} =\frac{18}{6} \\\\AQ=\frac{18}{6}*6.33\\\\AQ = 19[/tex]

[tex]\frac{BQ}{CQ}=\frac{AB}{CP} \\\\\frac{BQ}{8/3} =\frac{18}{6} \\\\BQ=\frac{18}{6}*\frac{8}{3} \\\\BQ =8[/tex]

Perimeter of BAQ = AB + BQ + AQ = 18 + 8 + 19 = 45cm

PA = AQ + PQ = 19 + 6.33 = 25.33

PD = CD + DP = 18 + 6 = 24

Perimeter of PDA = PA + PD + AD = 24 + 25.33 + 8 = 57.33 cm

Answer:

Step-by-step explanation:

sum of all the angles in a triangle=180

let the angles be 2x, 4x and 3x

so, 2x+4x+3x=180

9x=180

x=20

so smallest angle 2x= 2(20)= 40 degrees

Answer:

40° is the smallest angle of the triangle.

Answer:

  a. (5x+2)(5x+2)

Step-by-step explanation:

You will recognize that the first (25x^2) and last (4) terms are perfect squares. The middle term is double the product of the roots of those squares:

  2(5x)(2) = 20x

This means the given expression is a perfect square trinomial, and that it is the square of (5x+2). This matches the first choice.

  25x^2 +20x +4 = (5x +2)^2 = (5x +2)(5x +2)

_____

Generically, ...

  (a +b)^2 = a^2 +2ab +b^2

Here, we have a=5x, b=2.

Draw a picture. You have a 30-60-90 triangle, so the sides are in the ratio 1:√3:2.

The string of the kite is the side opposite the 90° angle. The side opposite the 30° angle is 25 ft.

The vertical leg of the triangle is 25√3 ≈ 43.3 ft

Answer:

0.33

Step-by-step explanation:

5.11-3.79=1.32

1.32÷4=0.33

After solving the equation, the price of each postcard will be equal to $0.33.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per information in the question,

Price of greeting card = $3.79

Total cost of greeting card as well as greeting card is $5.11

Let the price of each postcard is x.

Then, the equation will be,

$3.79 + 4x = $5.11

4x = $5.11 - $3.79

x = 1.32/4

x = $0.33

i know this becuase i did the equation in reverse, then used my calculator to make sure all the numbers added up.

Answer: B)

Step-by-step explanation:

First we need to find the value of the black sqaure. The value of the black square is 6 because 60 / 10 = 6. A) cannot be the answer because 6 does not equal 60. C) cannot be the answer because 10 does not equal 360. The only answer can be B) because 6 x 10 does equal 60.

Step-by-step explanation:

17 - 4 + 1 = 13 + 1 = 14

Answer:

Step-by-step explanation:

D = distance

[tex]x_{1}[/tex] = 4

[tex]x_{2}[/tex] = 17

No "y" values were given.

The distance formula:

[tex]D=\sqrt{(x_{1} - x_{2} )^{2} +(y_{1} - y_{2} )^{2}}[/tex]

If we insert in the values:

[tex]D = \sqrt{ (4 - 17)^{2} + (0 - 0)^{2}}[/tex]

(0-0)^2 = 0 so we can just remove the last part since it's +0:

[tex]D = \sqrt{(4 - 17)^{2}}[/tex]

4 - 17 is equal to -13:

[tex]D = \sqrt{(-13)^{2}}[/tex]

Since [tex](-a)^{2} = (a)^{2}[/tex], that means that the negative 13 becomes positive

[tex]D = \sqrt{(13)^{2}}[/tex]

Now the square root and the square cancels each other out:

[tex]D = 13[/tex]

803.84 ft ²

:)

The area of the circle is given by the equation A = 803.84 feet²

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle

Given data ,

Let the area of the circle be represented as A

Now , the equation will be

The radius of the circle r = 16 feet

So , area of the circle = πr²

Substituting the values in the equation , we get

Area of the circle A = π x ( 16 )²

Area of the circle A = π x 256

Area of the circle A = 3.14 x 256

Area of the circle A = 803.84 feet²

Therefore , the value of A is 803.84 feet²

Hence , the area of circle is 803.84 feet²

Answer:  rice a

Step-by-step explanation:

convert 1/5 to a decimal .20 <.25

Bag of rice B gives more rice than bag A as per the percentage.

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.

Given, A shop sells two different bags of rice. Rice A has 500g plus 25% extra free and Rice B has750g plus 1/5 extra free.

For calculating the free amount of rice,

For Bag A

Frre amount of rice  = 500* 25%  = 500 *25/ 100 = 125g

For Bag B

Frre amount of rice  = 750 * 1/5 = 150g

Therefore, According to the percentage, bag B of rice contains more rice than bag A.

Answer:

y=10x+9

after 4 years the gator will be 49 in long

Step-by-step explanation:

Answer:

y = 5/6x + 3/4.

At 4 years old,  the length y = 49/12 feet = 4 feet 1 inch.

Step-by-step explanation:

9 inches = 3/4 feet.

10 inches =  5/6 feet

So our equations is

y = 5/6x + 3/4.

When it is 4 years old:

y  = 5/6(4) + 3/4

= 20/6 + 3/4

= 49/12 feet
