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.

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.

Answer:

2 1/3 - -3 1/4 = 2 1/3 + 3 1/4 = 5 7/12

-1.25*-3 1/4 = 4.0625

Step-by-step explanation:

The greatest difference will be two numbers which subtracted give the largest value.

2 1/3 - -3 1/4 = 2 1/3 + 3 1/4 = 5 7/12

This is the greatest value because it is the greatest number and the least number.

The greatest product will be -1.25 and -3 1/4 since both numbers are negative they give a positive solution.

-1.25*-3 1/4 = 4.0625

Yes! This is true. line segment LM is dilated to create L'M' using point Q as the center of dilation and a scale factor of 2

This can be confirmed by the concept of similar triangles. The proportions of the sides are used to confirm this

The proportion used is: LQ / L'Q = 4 / (4 + 4 ) = 1/2

The scale factor is 2.

Remark

This is one of those questions that can throw you. The problem is that do you include the original rectangle or not. The way it is written it sounds like you shouldn't

However if you don't the question gives you 2 complex answers. (answers with the sqrt( - 1) in them.

Solution

Let the width = x

Let the length = x + 5

Area of the rectangle: L * w = x * (x + 5)

Area of the smaller squares (there are 2)

Area = 2*s^2

x = s

Area = 2 * x^2

Area of the larger squares = 2 * (x+5)^2

Total Area

x*(x + 5) + 2x^2 + 2(x + 5)^2 = 120                 Expand

x^2 + 5x + 2x^2 + 2(x^2 + 10x + 25) = 120     Remove the brackets

x^2 + 5x + 2x^2 + 2x^2 + 20x + 50 = 120      collect the like terms on the left

5x^2 + 25x +  50 = 120                                   Subtract 120 from both sides.

5x^2 + 25x - 70 = 0                                         Divide through by 5

x^2 + 5x - 14 = 0                                               Factor

(x + 7)(x - 2) = 0                                                 x + 7 has no meaning  

x - 2 =  0

x = 2                                                              

Perimeter

P = 2*w + 2*L

w = 2

L = 2 + 5

L = 7

P = 2*2 + 2 * 7

P = 4 + 14

P = 18

The answer to your question is 82%

The stadium is 87% filled with 13,920 people attending out of a maximum capacity of 16,000 seats.

To find out what percentage of the stadium's capacity is filled, we can use the formula: (Number of people in the stadium / Capacity of the stadium) × 100%. In this case, the stadium currently has 13,920 people and its capacity is 16,000 seats. We calculate the percentage like this:

(13,920 / 16,000) × 100% = 0.87 × 100% = 87%

Therefore, 87% of the stadium's capacity is filled.

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. $513

Step-by-step explanation:

Find the area of the boxes by multiplying the sides.

The first box is 54 ft sq.

The second box is 121.5 ft sq.

So

[tex]\\\frac{54}{121.5} =\frac{228}{x}[/tex]

Final answer:

The scale of the new blueprint is 1.5625, and the width of the new blueprint is 9.375 inches.

Explanation:

The original blueprint of the Moreno’s’ living room has a scale of 2 inches= 5 feet.

The family wants to use a new blueprint that shows the length of the living room to be 15 inches. If the width of the living room on the original blueprint is 6 inches and the length is 9.6 inches, what are the scale and the width of the new blueprint.

Calculate the scale using the original blueprint scale and the new length provided:

Scale = (New Length)/(Original Length) = 15/9.6 = 1.5625.

Calculate the width of the new blueprint using the original width and the scale:

Width of new blueprint = (Original Width) * (Scale) = 6 * 1.5625 = 9.375 inches.

Simplify it to 14x6

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.

Answer:

We can say that the graph g(x) is obtained by shifting the grapf f(x) by 2 units up.

Step-by-step explanation:

[tex]f(x) = 2^x[/tex]

[tex]g(x) = f(x) + k[/tex]

Rule : f(x)→f(x)+k

graph f(x) shifts upward by k units

Since we are given that [tex]g(x) = f(x) + k[/tex]

So, this means when graph f(x) shifts upward by k units then g(x) is obtained

We are given that k = 2

So, when graph f(x) shifts upward by 2 units then g(x) is obtained .

Thus we can say that the graph g(x) is obtained by shifting the grapf f(x) by 2 units up.

Answer:

The inverse function is f(x) = (x + 7)/2

Step-by-step explanation:

To find the inverse of any function, start by switching the x and f(x) values.

f(x) = 2x -7

x = 2f(x) - 7

Now solve for the new f(x). The result will be your inverse function.

x = 2f(x) - 7

x + 7 = 2f(x)

(x + 7)/2 = f(x)

The inverse of Y = 2x - 7 can be found by swapping the x and y variables and then solving for y, which gives the inverse function y = (x + 7) / 2.

To find the inverse of the function Y = 2x - 7, you can follow these steps:

So, the inverse of Y = 2x - 7 is y = (x + 7) / 2.

Answer:

your answer would be A. Brown v. Board of Education

Step-by-step explanation:

Answer:

The correct answer is the option A: Brown v. Board of Education.

Step-by-step explanation:

Brown v. Board of Education was a landmark decision by the Supreme Court of the United States in the year 1954, whose main purpose was to prohibited state laws, that were in favor of the racial segregation of schools, declaring them unconstitutional, due to the fact that these segregated schools violated the ''Equal Protection Clause'' of the Fourteenth Amendment of the United States' Constitution.

It all began in 1951 when the Brown family wanted to take her daughter to a school near their home, but the board education of the school refused and said that they must take her to a segregated black elementary school further away. Then, the family and other twelve families in similar situations initiated a class action lawsuit in U. S. federal court against the school's board of education located in Topeka, Kansas.
