Given:

The equation is:

[tex]\dfrac{y}{p-q}=\dfrac{y}{p+q}[/tex]

To find:

The value of y.

Solution:

We have,

[tex]\dfrac{y}{p-q}=\dfrac{y}{p+q}[/tex]

On cross multiplication, we get

[tex]y(p+q)=y(p-q)[/tex]

[tex]yp+yq=yp-yq[/tex]

[tex]yp+yq-yp+yq=0[/tex]

[tex]2yq=0[/tex]

Dividing both sides by 2q, we get

[tex]\dfrac{2yq}{2q}=\dfrac{0}{2q}[/tex]

[tex]y=0[/tex]

Therefore, the correct option is A.

Steven and James emerged from the trees and walked along a sloping open area to the river. The rippling river sparkled like diamonds in the sun, and the boys couldn't resist the urge to stop and soak up the scenery. They watched as tiny Insects danced a ballet across the water. As they rested their feet, both boys gazed north toward the unpredictable volcano il cd become so familiar with. It was magnificent, even with the usual cloud of steam rising above it. As they watched, though, they notice ething around them was changing. The cloud on the volcano's peak suddenly grew larger, and the ground began to shake beneath .. James said, "I wonder-" He didn't have time to finish the rest of his sentence. As they looked on in stunned silence, the top of Big White Peak suddenly exploded and erupted. For a split second, everything was soundless. Steven and James stared, mesmerized by a huge, dark cloud streaked with blue and orange flashes. Then, as the roar of the sound reached them, both boys jumped up and began to sprint back to their car. They scrambled up the rugged hillside, tripping over rocks and branches without stopping. "Look!" shouted James, looking over his shoulder as he ran. The cloud was growing larger, and it seemed to be coming toward them with a tremendous amount of speed. Steven didn't think they needed to be concerned about the cloud itself because the wind was blowing in the opposite direction and they were quite far from the crater. What he was worried ībout most , however, was that they might be caught in a flood. He hoped they could get away before the snow and ice from the Big White Peak melted in the heat of the eruption. The boys ran over the rugged terrain, glancing back nervously on the way to the car. As they drove away, heading for safety, they watched in amazement as a great wall of water carrying mud, rocks, and trees crashed down the mountain. In a matter of minutes, the grass and flowers were gone and the sparkling river had turned gray. Still numb with shock, they turned out of the park and onto the highway toward home.​

N 3 rows of 5. Colleen used tiles that measured 1 2 3 cm in length. Caroline used tiles that measured 3 1 3

Answers

Complete question :

Colleen and Caroline each built a rectangle out of square tiles placed in 3 rows of 5. Colleen used tiles that measured 1 2/3 cm in length. Caroline used tiles that measured 3 1/3 cm in length.

a. Draw the girls’ rectangles, and label the lengths and widths of each.

b. What are the areas of the rectangles in square centimeters?

c. Compare the areas of the rectangles.

Answer:

Colleen = 41.667 cm²

Carolina = 166.667 cm²

Carolina's rectangle is larger Than Collen's

Step-by-step explanation:

To start with, we determine the total number of tiles used

3 Rows of 5 ; 3 in 5 places = 15

Length of collen's square tiles : 1 2/3 = 5/3

Area of collen's square tiles = square of side length, = (5/3)² = 25/9

Area of rectangle formed = area of square * number of tiles

(25 /9) * 15 = 41.667 cm²

Length of carolina's square tiles : 3 1/3 = 10/3

Area of collen's square tiles = square of side length, = (10/3)² = 100/9

Area of rectangle formed = Area of square * number of tiles

(100/9) * 15 = 166.667 cm²

Carolina's rectangle is larger Than Collen's

What is a linear equation?

When an equation contains one or more variables with exponents as 1 then such equations are linear equations.

For example, 3x+2y=9 and 4y=6. The first equation is a linear equation with two variables and the second equation is with the linear equation in one variable.

Let the cost of a t-shirt is £m and the cost of a hat is £n.

Formulate two linear equations using the given statements in the question.

[tex]2m+3n=12\,\,\, ...(1)\\5m+4n=23\,\,\, ...(2)[/tex]

Obtain the value of m from equation (1).

[tex]2m=12-3n\\m=\frac{12-3n}{2}[/tex]

Substitute the obtained value of m into equation (1) and find n.

[tex]5 \times(\frac{12-3n}{2})+4n=23\\ 60-15n+8n=46\\14=7n\\n=2[/tex]

Substitute the value of n into [tex]m=\frac{12-3n}{2}[/tex]and obtain the value of m.

[tex]m=\frac{12-3(2)}{2}\\=\frac{12-6}{2}\\ =\frac{6}{2}\\ =3[/tex]

Thus, the cost of a t-shirt is £3 and the cost of a hat is £2.

If Sarah walks to the Springdale Town Center from the Ferguson

Corporation and then to the Subway Station, how much farther will she

walk than if she walks directly to the Subway Station from the Ferguson

Corporation? Show all of your work.

Answers

Answer:

1263.7032 feets

Step-by-step explanation:

Distance from Ferguson corporation to Springdale Town center ; let the distance = x

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 27 = x / 2000

0.5095254 * 2000 = x

1019.0508 feets

Distance from Springdale to Subway station, this is the hypotenuse :

Hypotenuse = √(1019.0508² + 2000²)

Hypotenuse = √5038464.7

Hypotenuse = 2244.6524 feets

Total distance walked from Ferguson to Springdale, then to Subway ;

(1019.0508 + 2244.6524) feets = 3263.7032 feets

Additional distance walked :

(3263.7032 feets - 2000 feets) = 1263.7032

In this exercise we have to calculate the distance knowing about the laws of a triangle, so we have to:

[tex]H=1263.7032 feets[/tex]

We can use the definition of tangent to calculate:

[tex]Tan\theta = opposite / Adjacent\\Tan 27 = X / 2000\\0.5095254 * 2000 = X\\=1019.0508 feets[/tex]

Now using the Pythagorean theorem we have:

[tex]H = \sqrt{(1019.0508^2 + 2000^2)}\\H = \sqrt{5038464.7}\\H = 2244.6524 feets\\(1019.0508 + 2244.6524) = 3263.7032 feets\\(3263.7032 feets - 2000 feets) = 1263.7032[/tex]

here we have this:

Considering the provided mathematical operation, we are going to identify wich is the correct statement, so we obtain the following:

Since the remainder is zero, it means that setting the divisor and quotient equal to zero gives us the roots, then we have:

2x-1=0

2x=1

x=1/2

and, we have,

x+5=0

x=-5

Finally we obtain that the roots are 1/2 and -5, then the correct answer is the option C.
