what is the answer

Answer:

544

Step-by-step explanation:

   136 * ( 8 + (-4 ) = 136 * 8 + [ 136 * (-4) ]

                           = 1088 - 544

                           = 544

Answer: The sum of a number and its square is 6. Find the number

Step-by-step explanation:

n + n^2 = 6 n^2 + n - 6 = 0 factoring ___ (n + 3)(n - 2) = 0 n + 3 = 0 ___ n = -3 n - 2 = 0 ___ n = 2 two solutions 

Answer:

n = -3, 2

Step-by-step explanation:

We're given:

Let the number be n.

[tex]n+n^2=6[/tex]

⇒ Move everything to one side of the equation:

[tex]n+n^2-6=0[/tex]

⇒ Organize in [tex]ax^2+bx+c=0[/tex] form:

[tex]n^2+n-6=0[/tex]

⇒ Factor:

[tex]n^2-2n+3n-6=0\\n(n-2)+3(n-2)=0\\(n+3)(n-2)=0[/tex]

⇒ Use the zero-product property to find n:

[tex]n+3=0\\n=-3[/tex]       or       [tex]n-2=0\\n=2[/tex]

Answer:

x = 30º

Step-by-step explanation:

Let's call the midpoint of OP, R.

The triangle of OQR would be an equilateral triangle since OQ = OR as they are both radii and is OQR and ORQ are 60º, ROQ is also 60º, making the triangle equilateral. Because tangents meet a circle at 90º, the angle RQP would be 30º and since angles on a straight line add to 180º, the angle QRP would be 180-ORQ which is 120º. Now we know the 2 angles in triangle of QRP so we can work out the final angle since angles in a triangle add to 180º. So:

180 - 120 - 30 = 30º.

x = 30º

This would also prove that QR and RP are the same since base angles in an isosceles triangle are equal.

Step-by-step explanation:

1/5x -2/3y =30

Plug in 15 for y.

x-(15)= 30

2/3x of 2/3(15) is 10.

1/5x -10-30

Add 10 to each side.

1/5x = 40

Divide each side by 1/5.

(dividing by a fraction is the same as multiplying by its reciprocal...flip 1/5...*5)

x=200

Step-by-step explanation:

What is a dilation?

A dilation is a type of transformation that resizes an object.

To apply a dilation ( find the coordinates of a point after a dilation ) you must multiply the x and y values of the coordinates by the scale factor

Applying the dilation rule

We want to find the coordinate of vertex B after a dilation with a scale factor of 2. To do so we multiply the x and y value of vertex b by the scale factor or 2

Current coordinates of the triangle :

Coordinates after dilation

A' = (1,1) ===> (1×2,1×2) ===> (2,2)

B' = (1,3) ===> (1×2,3×2) ===> (2,6)

C' = (3,1) ===> (3×2,1×2) ===> (6,2)

The coordinate of the vertex B after the dilation is (2,6)

The rectangular pool where Asha swims would need 4.6875 * 10⁸ cm³ of water to make it full.

An equation is an expression that shows the relationship between two or more numbers and variables.

The pool where Asha swims is rectangular. It is 2500 cm long, 1250 cm wide and 150 cm deep.

Hence:

Volume of the pool = 2500 * 1250 * 150 = 4.6875 * 10⁸ cm³

The probability when x is greater than 120 is 0.0367. Then the correct option is D.

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The mean is 95 and the standard deviation is 14. Then the probability when x > 120 will be

The z-score will be

z = (120 - 95)/ 14

z = 1.7857

Then the probability will be

P(x > 120) = P(z > 1.7857)

P(x > 120) = 1 - P(x<120)

P(x > 120) = 1 - 0.96293

P(x > 120) = 0.0367

The similarities and differences in a non-fiction text look at how the subject or events are portrayed.

Comparing non-fiction texts can focus on the similarities between the texts - things they have in common. You can also contrast texts and focus on their differences - things that set the texts apart from each other. You could compare and contrast the following:

Form – What types of text (letter, news report, etc) are they?

Purpose – What job (persuading, informing, advertising) is each text doing?

Audience – Who is the intended reader of the text?

Subject matter – What are the texts about?

Language choices – What kinds of words, images or rhetorical devices are being used?

Structure – How is the text ordered?

Tone – What is the overall tone or mood of the writing?

Non-fiction texts are all around us, and comparing them can help you become more aware of how language is being used in society. Comparing non-fiction texts can often prompt you to notice things that you might not have considered about a text in isolation.

Hence the similarities and differences in a non-fiction text look at how the subject or events are portrayed.
