What scale factor was applied to the first rectangle to get the result image?

The perimeter of given square is 4(s + 3)

Given that:

One side of square has length  = (s+3)

A square is a geometric figure having 4 equal straight sides and all internal angles are of 90 degrees.

Perimeter of a closed figure is a measure  of length of all the lines needed to construct that figure.

Perimeter of square of side a is thus a + a + a + a = 4a.

Here given is a = (s+3)

Thus perimeter of given square with side (s+3) is 4(s+3).

Answer:

Concentration.

Step-by-step explanation:

Concentration: It is define as the amount of substance  per unit volume.

Or

Concentration is defined as the ratio of solute in a solution to either solvent or total solution.

Concentration usually is expressed in terms of mass per unit volume.

When the amount of a substance in a given volume is increased then it alter the concentration of reactant.When the concentration of reactant is increase then the rate of reaction  increases.Because when the concentration is increases then more ions or molecules interact to form new compounds therefore, the rate of reaction  increases.When the concentration of reactant decrease then less number of ions or molecules interact to form new compounds therefore, the rate of reaction decreases.

Answer:

Area of the border is 142.80 ft²

Step-by-step explanation:

The given figure consist of three figures = 2× semicircles + 1 square.

We will calculate area of the figure including border

Area of one semicircle = (1/2)π×r²= (1/2)×π×(12/2)² = (1/2)π×(6)² = 18π ft²

Area of square = side² = 12² = 144 ft²

Total area = 144 + 18π + 18π = (144 + 36π) ft²

Now we will calculate area without border.

Area of the semicircle = (1/2)π×r² =(1/2)π×[(12-4)/2]²=(1/2)π×(4)² = 8π ft²

area of square = side²= (12-4)²= 8² = 64 ft²

Total area = 64 + 8π + 8π = (64 + 16π) ft²

Now the area of the border = Area with border - Area without border

= (144 + 36π) - (64 + 16π) = 20π + (144 - 64) = 20π + 80

= 20×3.14 + 80 = 142.80 ft²

Area of the border = 142.80 ft²

The area of the flower border surrounding the heart-shaped pond is approximately 142.80 square feet.

The given figure consists of three parts: two semicircles and one square. Let's calculate the area of the border step by step:

1. Area of the Semicircles:

  - The semicircles form the rounded top of the heart shape.

  - Each semicircle has a radius of half the width of the pond, which is [tex]\(12 \, \text{ft}\)[/tex].

  - Area of one semicircle = [tex]\(\frac{1}{2} \pi r^2\)[/tex]

[tex]\[ = \frac{1}{2} \pi (6)^2 = 18\pi \, \text{ft}^2\][/tex]

  - Total area contributed by both semicircles = [tex]\(2 \times 18\pi = 36\pi \, \text{ft}^2\)[/tex]

2. Area of the Square:

  - The square section of the pond has sides of [tex]\(10 \, \text{ft}\)[/tex] each.

  - Area of the square = side squared

[tex]\[ = 10^2 = 100 \, \text{ft}^2\][/tex]

3. Total Area Including Border:

  - Total area = Area of semicircles + Area of square

[tex]\[ = 144 + 36\pi \, \text{ft}^2\][/tex]

4. Area Without Border:

  - To find the area without the border, we subtract the area of the pond from the total area:

  [tex]\[ = 100 + 16\pi \, \text{ft}^2\][/tex]

5. Area of the Border:

  - The area of the border is the difference between the total area and the area without the border:

[tex]\[ = (144 + 36\pi) - (100 + 16\pi) = 20\pi + 80 = 20 \times 3.14 + 80 = 142.80 \, \text{ft}^2\][/tex]

Therefore, the area of the flower border surrounding the heart-shaped pond is approximately 142.80 square feet.

The two equations a+b=-7, a-b=14 can be solved to get these results. It is genrally convenient to solve them by adding one to the other, or subtracting one from the other.

The equation of line is slope intercept form is y = 2x + 3

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

2x - y = -3   be equation (1)

Adding 3 on both sides of the equation , we get

2x - y + 3 = 0

Adding y on both sides of the equation , we get

y = 2x - 3

Now , equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

Therefore , the value of A is 2x - 3  , where the slope is m = 2

Hence , the equation of line is y = 2x - 3

Final answer:

To convert the equation 2x-y=-3 into slope-intercept form, y must be isolated. The steps involve rearranging the equation to solve for y, resulting in the slope-intercept form y = 2x + 3, where the slope (m) is 2 and the y-intercept (b) is 3.

Explanation:

To convert the equation 2x-y=-3 into slope-intercept form, we need to solve for y. The slope-intercept form of a linear equation is y = mx + b, where m represents the slope, and b represents the y-intercept.

Let's solve for y:

Therefore, the equation 2x - y = -3 in slope-intercept form is y = 2x + 3.

After walking for 2 days she raised a total of $12.5.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given, Ana participated in a charity walk. She raised $0.25 for each 1/2 mile that she walked.

Since, for 1/2 miles she earns money = 0.25

Thus,

For 1 mile she will earn a total of money = 0.25* 2

For 1 mile she will earn a total of money = 0.5

Since Ana ran for 2 days, The first day Ana walked 11 miles. On the second day, she walked 14 miles.

So,

Total of miles she walked = 11 + 14

The total of miles she walked = 25

Thus,

She raised a total amount of money = 25 *0.5

She raised a total amount of money = 12.5$

Therefore, after walking for 2 days she raised a total of $12.5.

so the area of square will be :

A = a²

  = 14 x 14

  = 196 square inches

The square that has twice the area of this square means double the area :

196 x 2 = 392 square inches

To find one side of the square:
