Georgia  takes 24 minutes to clean the espresso machine by herself.

The correct answer is an option D.

The equation for the situation is:

[tex]\frac{1}{x} +\frac{1}{x-12} =\frac{1}{8}[/tex]

here, x is the number of minutes it takes Georgia to clean the machine by herself.

We need to find the value of x.

Consider the equation,

[tex]\frac{1}{x} +\frac{1}{x-12} =\frac{1}{8} \\\\\frac{(x -12)+x}{x(x-12)}=\frac{1}{8}\\\\\frac{x -12+x}{x^2-12x}=\frac{1}{8}[/tex]

(2x - 12) × 8 = x² - 12x

16x - 96 =  x² - 12x

x² - 12x -16x + 96 = 0

x² - 28x + 96 = 0

x²-24x-4x+96 = 0

(x - 24)(x - 4) = 0

x = 24 or x = 4

If x = 4, then x - 12 would be negative which is not possible.

Thus, it takes 24 minutes for Georgia.

Find the complete question below.

The lines, y = -1 and x = 1 are perpendicular lines.

If two lines are perpendicular to each other, it means they form right angle at the point of intersection, and also, they have slopes that are negative reciprocals to each other.

Also, vertical and horizontal lines are perpendicular to each other because horizontal line has a slope that is zero while vertical line has an undefined slope.

y = -1 is a horizontal line, while x = 1 is a vertical line. Therefore, we can concluded that, they are perpendicular to each other.

Answer:

y =  [tex]\frac{1}{3}[/tex]x + 6

Step-by-step explanation:

The equation we currently have right now is y = -3x+2. Since we know that the line equation is y = mx + b, let's take out m to find the slope of a perpendicular line. M will be -3.

To convert a regular slope to a perpendicular one, we have to:

- reciprocal/flip it (this means that if m = 3, the perpendicular will be [tex]\frac{1}{3}[/tex])

- swap the signs (this will mean that if a number is positive, then it will become negative)

Therefore, if m = -3, the perpendicular slope will be [tex]\frac{1}{3}[/tex] (we flipped and changed signs)

Now, we are also given that this line passes through the point (6,8), so we can use this formula: [tex]y - y1 = m(x-x1)[/tex]

What do we know right now?

- y1 = 8 (from (6,8))

- x1 = 6 (from (6,8))

- m =  [tex]\frac{1}{3}[/tex]

Let's plug in what we know:

y - 8 =  [tex]\frac{1}{3}[/tex](x - 6)

y =  [tex]\frac{1}{3}[/tex](x-6) + 8

y =  [tex]\frac{1}{3}[/tex]x - 2 + 8

y =  [tex]\frac{1}{3}[/tex]x + 6

The estimated weight of three containers weighing 1. 656 kg each =  5 kg

Let w represents the weight of each contaoner.

Here, each container weighs 1.656 kg

Here, the weight of all containers are the same.

To determine the estimated weight of three containers we us the Unitary method.

We simply multiply the given weight by the number of containers.

Let W be the estimated weight of three containers.

A quadrilateral in geometry is a four-sided polygon with four edges and four corners.

Given:

ABCD is a quadrilateral.

m∠A =80°, m∠B = 100° and m∠D = 110°.

The sum of all the interior angles is 360°.

m∠A + m∠B + m∠C + m∠D = 360°.

https://brainly.com/question/6321910

#SPJ1

Step-by-step explanation:

In a quadrilateral, the sum of the measures of the angles is 360 degrees. Therefore, if we know the measures of three of the angles in a quadrilateral, we can use this information to find the measure of the fourth angle.

In this case, we know that:

m(<A) = 80 degrees

m(<B) = 100 degrees

m(<D) = 110 degrees

So, to find m(<C), we can use the equation:

m(<A) + m(<B) + m(<C) + m(<D) = 360

Substituting in the known values, we get:

80 + 100 + m(<C) + 110 = 360

Solving for m(<C), we get:

m(<C) = 360 - (80 + 100 + 110) = 360 - 290 = 70 degrees

So the measure of angle C is 70 degrees.

The required average speed of the train is calculated to be 60 mph, when the train travels certain distance and stops.  

Distance between station A and station B is given as 120 miles.

A train traveling from station A to station B travels exactly 1/3rd of the distance when it is held up and stops for 16 minutes.

Let, its average speed was x mph.

Then, total time taken if it didn't stop = 120/x h

Now, before stop it took time = ( 1/3 × 120)/x h = (40/x) h

After stop the time it took = 80/(x + 15) h

i.e, 40/x + 16/60 + 80/(x+15) = 120/x  

⇒ 80/(x + 15) + 8/30 = 80/x

⇒ 80(1/x - 1/(x + 15)) = 8/30

⇒ 10 × (15/x² + 15x) = 1/30

⇒ x² + 15x = 10 × 15 × 30

⇒ x² +15x - 450 = 0

⇒ x² +75x -60x - 450 = 0

⇒ (x+75)(x-60) = 0

⇒ x = 60 or, x = -75

As speed cannot be negative, the average speed is 60 mph.

What is Quadratic Equation?

The polynomial equations of degree two in one variable of type f(x) = ax2 + bx + c = 0 and with a, b, c, and R R and a 0 are known as quadratic equations. It is a quadratic equation in its general form, where "a" stands for the leading coefficient and "c" is for the absolute term of f. (x).

A = l x w

l = 2w-4

A = w (2w-4)

A = 2w² -4w

96m² = 2w² - 4w

0 = 2w² - 4w - 96 divide both sides by 2

0 = w² - 2w -48

(w-8) ( w +6) = 0

Let A be the event that a leaf completes the color transformation and B be the event that a leaf completes the textural transformation.

n(B) = 243 +  13  = 256

Finding the Probability of the event that the leaf completes the color transformation by using the Probability of an event formula

P(A)= 269 / 300

A square is a special type of rectangle. All squares are rectangles, but not all rectangles are squares.

In contrast, a rectangle can have sides of different lengths.

Answer:

X = C - B

--------

A

Step-by-step explanation:

Solving for X is pretty much getting X alone on one side of the equal sign. That's when we would do the "opposite" of what the original equation is showing. And we do that to both sides.

For example, we see +b. The opposite of addition is subtraction, so we do just that. We do -b on BOTH sides of the equal sign. b -b = 0. It cancels it out. c-b is just as it says. So now we have ax = c-b.

Now we see ax are right next to each other with no symbol, which means they are being multiplied. The opposite of multiplication is division. So we'll do that exactly. We will divide A on both sides. ax/a gets rid of that a and leaves the x alone. Dividing c-b/a gives you just that, making the answer X = C-B/A

At the margins of the coordinate plane, the curve approaches lines known as asymptotes. When the denominator of such a rational function gets close to zero, vertical asymptotes happen. Since it would divide by zero, a rational function never traverse a vertical asymptote.
