Answer:

x>-20/7

Step-by-step explanation:

Answer:

x > 2.8671

Step-by-step explanation:

Answer:

180 - (52 + 28) = x and then x = 100.

Step-by-step explanation:

A triangle's angles must ALWAYS add up to 180. No matter what. So, the problem gives us 2 of the three angles already, 52 and 28. 52 + 28 is 80. As I mentioned before, a triangle's angles must always add up to 180, so to find x, you must subtract 80 from 180, getting 100. Therefore, x is 100 degrees.

The equation we used to find that is: 180 - (52 + 28) = x.

52 and 28 are the two angles we know, and subtracting their sum from 180 gives us the missing angle.

Step-by-step explanation:

Given:

Width of the canvas = 49 inches

The height of the canvas is 3 inches less than the width.

To find:

The area of the canvas.

Solution:

It is given that,

Width of the canvas = 49 inches

The height of the canvas is 3 inches less than the width

So, the height of the canvas is:

[tex]h=49-3[/tex]

[tex]h=46[/tex]

We know that the shape of the canvas is a rectangle and the area of the rectangle is:

[tex]A=length\times width[/tex]

The two dimensions of the canvas are  46 inches and 49 inches. So, the area of the canvas is:

[tex]A=46\times 49[/tex]

[tex]A=2254[/tex]

Therefore, the area of the canvas is 2254 square inches.

Answer:

A.

Step-by-step explanation:

The lines touch along every point so they are on top of each other.

The given system of equations represent two coinciding lines.

A system of linear equations is a group of  equations having same number of variables and degree.

For the n number of variables n number of equations are required.

On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.

A linear equation in two variables represent a straight line.

As system of equations in two variables can be represented as

a₁x + b₊y + c₁ = 0

a₂x + b₂y + c₂ = 0

When there are two such equations having infinite solutions the relation between the coefficients is given as,

a₁/a₂ = b₁/b₂ = c₁/c₂

It implies that there are infinite points common between them which is possible only when these two lines are coinciding.

Hence, the graph of corresponding two lines in the x- y plane represents coinciding lines.

Answer:

Step-by-step explanation:

Answer:

[tex]Pr = \frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]n = 4[/tex]

Required

Probability that you seat on the far left

First, we calculate the total possible seat arrangements.

This is calculated using:

[tex]Total =n![/tex]

[tex]Total =4![/tex]

[tex]Total =4*3*2*1[/tex]

[tex]Total =24[/tex]

Next, the possible seat arrangements if you seat at the far left.

This implies that you can only seat 1 spot while your friends (3) can seat on any of the remaining 3 seats.

i.e.

[tex]You \to 1[/tex]

[tex]Friend\ 1,2,3 \to 3,2,1[/tex]

The number of arrangement is:

[tex]Arrangement = 1 * 3 *2 *1[/tex]

[tex]Arrangement = 6[/tex]

The required probability is:

[tex]Pr = \frac{Arrangement}{Total}[/tex]

[tex]Pr = \frac{6}{24}[/tex]

Simplify

[tex]Pr = \frac{1}{4}[/tex]

Answer:

[tex]g(x) = 4(x - 2)^2 -9[/tex]

Step-by-step explanation:

Given

[tex]g(x) = 4x^2 - 16x + 7[/tex]

Required

Complete the square

Rewrite so that [tex]x^2[/tex] has 1 coefficient

[tex]g(x) = 4(x^2 - 4x) + 7[/tex]

Take half of the coefficient of x

[tex]\frac{4}{2} = 2[/tex]

Square the result

[tex](\frac{4}{2})^2 = 2^2[/tex]

[tex](\frac{4}{2})^2 = 4[/tex]

Add and subtract the result in the bracket

[tex]g(x) = 4(x^2 - 4x + 4 - 4) + 7[/tex]

Expand the bracket to remove -4

[tex]g(x) = 4(x^2 - 4x + 4) - 16 + 7[/tex]

[tex]g(x) = 4(x^2 - 4x + 4) -9[/tex]

Expand the bracket

[tex]g(x) = 4(x^2 - 2x -2x+ 4) -9[/tex]

Factorize

[tex]g(x) = 4(x(x - 2) -2(x-2)) -9[/tex]

Factor out x - 2

[tex]g(x) = 4((x - 2)(x-2)) -9[/tex]

Express as square

[tex]g(x) = 4(x - 2)^2 -9[/tex]

The probability of getting a number less than or equal to 5 is 5/6.

"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one".

For the given situation,

Stella rolls a standard six-sided die, numbered from 1 to 6.

The sample space for rolling a single die = {1, 2, 3, 4, 5, 6}

⇒[tex]n(s)=6[/tex]

The event is getting a number less than or equal to 5.

E = { [tex]{1, 2, 3, 4, 5}[/tex] }

⇒[tex]n(e)=5[/tex]

Thus the probability of getting a number less than or equal to 5,

[tex]P(e) =\frac{n(e)}{n(s)}[/tex]

⇒[tex]P(e)=\frac{5}{6}[/tex]

Hence we can conclude that the probability of getting a number less than or equal to 5 is 5/6.
