Answer:

36 square feet outdoor carpet will be required for this hole.

Step-by-step explanation:

A triangle colored in green with a rectangular hole has been given in the figure.

Area of the outdoor carpet will be calculated by the expression,

Area of the carpet = Area of the right triangle - Area of the rectangle removed from the triangle

Area of the right triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                         = [tex]\frac{1}{2}\times (12)\times (7)[/tex]

                                         = 42 square ft

Area of the rectangle = Length × Width

                                   = 3×2

                                   = 6 square ft

Area of the remaining area to be covered with the carpet = 42 - 6

= 36 square feet

Therefore, area of the outdoor carpet required for the hole = 36 feet²

Answer:

x = 7

Step-by-step explanation:

The triangles are similar, and they have a scale factor of 1/7 because 14 / 7 = 2.

Following the scale factor, you divide 49 by 7 to get 7.

The value of x in the second triangle is 7.

To determine the value of x in the diagram, we need to use the concept of similar triangles.

Two triangles are similar if their corresponding angles are equal and their sides are in proportion.

In this case, we have two triangles:

Triangle with sides 14 and 49.

Triangle with sides 2 and x.

Since both triangles are similar, we can set up a proportion using their corresponding sides:

(14 / 2) = (49 / x)

Now, we can solve for x:

(14 / 2) = (49 / x)

7 = 49 / x

To solve for x, we can multiply both sides of the equation by x:

7x = 49

Now, divide both sides by 7 to isolate x:

x = 49 / 7

x = 7

So, the value of x in the second triangle is 7.

The average number of items in all the gift bags is [tex]7.4[/tex].

To find the average number of items in all the gift bags, we need to consider the distribution of the bags and their respective average items.

Given:

50% of the bags are green with an average of 8 items per bag.

20% of the bags are yellow with an average of 5 items per bag.

30% of the bags are blue with an average of 8 items per bag.

Let's calculate the average number of items across all gift bags:

1. Calculate the total number of bags:

Total bags = 50% (green) + 20% (yellow) + 30% (blue) = 100%

2. Calculate the weighted average of items:

[tex]\[ \text{Average items per bag} = \left(0.50 \times 8\right) + \left(0.20 \times 5\right) + \left(0.30 \times 8\right) \][/tex]

Answer:  The correct option is (C) $342.

Step-by-step explanation:  Given that Mr. Williams is building a sand box for his children and is costs $228 for the sand if he builds a rectangular-sand box with dimensions 9 ft by 6 ft.

We are to find the cost of the sand if he decides to increase the size to [tex]13\frac{1}{2}~\textup{ft by }9~\textup{ft}.[/tex]

Since the box is empty from inside, so we will be considering the perimeter of the box, not area.

The perimeter of the rectangular-sand box with dimensions 9 ft by 6 ft is

[tex]P_1=2(9+6)=30~\textup{ft},[/tex]

and the perimeter of the rectangular-sand box with dimensions [tex]13\frac{1}{2}~\textup{ft by }9~\textup{ft}.[/tex] is

[tex]P_2=2\left(13\dfrac{1}{2}\times9\right)=2(13.5\times9)=45~\textup{ft}.[/tex]

Now, we will be using the UNITARY method.

Cost of sand for building rectangular-sand box with perimeter 30ft = $228.

So, cost of  sand for building rectangular-sand box with perimeter 1 ft will be

[tex]\$\dfrac{228}{30}.[/tex]

Therefore, the cost of sand for building rectangular-sand box with perimeter 45 ft is given by

[tex]\$\dfrac{228}{30}\times45=\$342.[/tex]

Thus, the required cost of the sand is $342.

Option (C) is CORRECT.

Answer:

a = 15

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

a +25+140 = 180

Combine like terms

a +165 = 180

Subtract 165 from each side

a+165-165 = 180-165

a = 15

Answer:

15 degrees

Step-by-step explanation:

In order to have a triangle, all the angles must add up to 180. Since we already have 2 or the three angles, we just add the two angles we have and subtract by 180 (working backwards!). 140 + 25 is equal to 165, and 180 - 165 is 15. Thus, 15 must be your answer.

The area of a sector can be calculated using a given formula. After adjusting for the given radius and angle, the approximate area of the sector is 31.1 cm^2.

Without specifications about the figure, let's consider it as a sector of a circle.

The area of a sector can be calculated using the formula Area = (angle / 360) * π * (radius)^2.

But here we are given the base length, which is actually the diameter for the whole circle.

Hence, the radius would be base/2 which is 9/2 = 4.5 cm.

So, by substituting the given values in the formula, the area will be Area = (140 / 360) * π * (4.5)^2 = 31.07 cm^2 approx. So, the area of the figure to the nearest tenth is 31.1 cm^2.

Answer:

B: 192pi - 144

Step-by-step explanation:

Area of the sector = (120/360) * pi * r^2

Area of the sector = 1/3 * pi * 24 * 24

Area of the sector = 192 * pi

Now to find the area of the triangle.

The triangle is an isosceles triangle That means two of its sides are equal. They are equal to the radius of the circle, which is 24.

the small angles are equal to

2x + 120 = 180    Subtract 120 from both sides

2x = 60               Divide by 2

x = 60/2

x = 30

The height of the triangle is derived from sin(30) = opposite / hypotenuse

sin(30) = 1/2

hypotenuse = 24

1/2 = opposite / hypotenuse

1/2 = opposite / 24                      Multiply both sides by 24

1/2 * 24 = opposite

opposite = 12

The height = 12

r = 24

Area of the triangle = 1/2 * 12 * 24

Area of the triangle = 144

So the area of the shaded area = 192*pi - 144 which looks like B

The area of the shaded region of the circle in terms of pi is 192π - 144√3 m².

The correct option is B) 192π - 144√3 m².

The shaded area of the circle is a segment, to determine the area of the segment, we simply subtract the area of the triangle from the area of the sector.

Note that; the area of a sector is expressed as:

Area = (θ/360) × πr²

Area of a triangle can be expressed as:

Area = ab × (sinθ)/2

Hence, the area of the shaded region will be:

Area = ( (θ/360) × πr² ) - ( ab × (sinθ)/2 )

Plug in the values and simplify:

Area = ( (120/360) × π × 24² ) - ( 24 × 24 × (sin120)/2 )

Area = ( 192π ) - ( 144√3 )

Area = 192π - 144√3

Therefore, the shaded area measures 192π - 144√3 square meters.

Option B) 192π - 144√3 m² is the correct answer.

B. the answer would be hyperbola

Answer:

Option 2 - Hyperbola

Step-by-step explanation:

Given : The polar equation [tex]r=\frac{1}{4-6\cos\theta}[/tex]

To find : What conic section is represented by the polar equation?

Solution :

To find the conic section first we convert the polar into Cartesian equation    

We know,  [tex]r=\sqrt{x^2+y^2}[/tex] and [tex]x=r\cos\theta[/tex]              

[tex]r=\frac{1}{4-6\cos\theta}[/tex]

[tex]4r-6r\cos\theta=1[/tex]      

Substitute the value of r,

[tex]4(\sqrt{x^2+y^2})-6x=1[/tex]      

[tex]4\sqrt{x^2+y^2}=1+6x[/tex]        

Squaring both side,

[tex]16(x^2+y^2)=(1+6x)^2[/tex]      

[tex]16x^2+16y^2=1+36x^2+12x[/tex]      

[tex]16y^2=20x^2+12x+1[/tex]      

Applying completing the square we get,

[tex]16y^2=20(x+\frac{3}{10})^2-\frac{4}{5}[/tex]

[tex]16y^2-20(x+\frac{3}{10})^2=-\frac{4}{5}[/tex]

[tex]\frac{16y^2}{-\frac{4}{5}}-{20(x+\frac{3}{10})^2}{-\frac{4}{5}}=1[/tex]

[tex]-\frac{y^2}{\frac{1}{4}}+{(x+\frac{3}{10})^2}{\frac{1}{25}}=1[/tex]

[tex]{(x+\frac{3}{10})^2}{\frac{1}{25}}-\frac{y^2}{\frac{1}{4}}=1[/tex]

This is in the form of hyperbola equation i.e. [tex]\frac{x^2}{a^2}-\frac{y^2}{b^2} =1[/tex]

Therefore, The given conic section is a hyperbola.

Hence, Option 2 is correct.

[tex]5(2x + 7) = 10x + 35[/tex]

We have a polynomial expression:

= 5(2x+7)

By using the distributive property we get

(x +4)^2 = 49

x = -11

x = 3

The values of x in the given quadratic equation by completing the square are -11 and 3.

Hence, option A)-11,3 is the correct answer.

Quadratic equation is simply an algebraic expression of the second degree in x. Quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown

Given th equation in the question;

x² + 8x = 33

Using completing the square method

First we take the half of the x term and square it

( 8/2 )² = 16

Now we add 16 to both sides

x² + 8x + 16 = 33 + 16

Next, we rewrite the perfect square on the left

( x + 4 )² = 33 + 16

( x + 4 )² = 49

We take square root of both sides

x + 4 = √49

x = -4 ± √49

x = -4 ± 7

x = -4 - 7 or -4 + 7

x = -11 or 3

x = -11, 3

The values of x in the given quadratic equation by completing the square are -11 and 3.

Hence, option A)-11,3 is the correct answer.

Step-by-step explanation:

The straight line distance between two points can be considered to be the hypotenuse of a right triangle. In this case, the legs of the triangle are the distance east and the distance north. The Pythagorean theorem describes the relation between the legs (a, b) and the hypotenuse (c).

  c² = a² +b²

  c² = 60² +25² = 3600 +625 = 4225

  c = √4225 = 65

The two airports are 65 miles apart.

Additional comment

You may recognize that the greatest common factor of 25 and 60 is 5, which means these numbers have the ratio 5 : 12. You may also recognize these as being the two smaller numbers in the Pythagorean triple {5, 12, 13}. That is, you expect the airports to be 5×13 = 65 miles apart.

The distance between the two airports is 65 miles.

Let's denote the distance east as [tex]$d_e = 60$[/tex] miles and the distance north as [tex]$d_n = 25$[/tex] miles. The distance between the two airports, which is the hypotenuse of the right-angled triangle formed by the two distances, can be calculated as follows:

[tex]\[ d = \sqrt{d_e^2 + d_n^2} \][/tex]

Substituting the given values:

[tex]\[ d = \sqrt{60^2 + 25^2} \] \[ d = \sqrt{3600 + 625} \] \[ d = \sqrt{4225} \] \[ d = 65 \][/tex]

Therefore, the distance between the two airports is 65 miles.
