The equivalent fraction for 1, using the number line and dividing it into four equal parts, is 1/4.

To find an equivalent fraction using a number line, we need to determine a fraction that represents the same value as the given fraction.

Let's assume the given fraction is 1. On a number line, the fraction 1 can be represented as the distance between 0 and 1. Now, we want to find an equivalent fraction, so let's choose a different representation on the number line.

To find an equivalent fraction that represents the same value, we can divide the number line segment between 0 and 1 into equal parts. Let's say we divide it into 4 equal parts.

Now, we need to determine which of the four equal parts represents the fraction 1. Since we divided the segment into four equal parts, each part represents 1/4 (one-fourth) of the whole segment.

Therefore, the equivalent fraction for 1, using the number line and dividing it into four equal parts, is 1/4.

The total surface area required to wrap the 15 cubed-shaped gift boxes is 3.6 square meters.

To calculate the total surface area of 15 cubed-shaped gift boxes, we need to find the surface area of one gift box and then multiply it by the total number of boxes.

The surface area of a cube can be calculated using the formula:

Surface Area = 6 * [tex](side length)^2[/tex]

Given that the length of each side of the cube-shaped gift box is 20 cm, we can substitute this value into the formula:

Surface Area of one gift box = 6 * (20 cm)^2

= 6 * [tex](400 cm^2)[/tex]

= 2400 [tex]cm^2[/tex]

Since we have 15 gift boxes, we multiply the surface area of one gift box by 15:

Total Surface Area = Surface Area of one gift box * Number of gift boxes

= 2400 [tex]cm^2 * 15[/tex]

= 36000 [tex]cm^2[/tex]

Now, we need to convert the area from square centimeters [tex](cm^2[/tex]) to square meters [tex](m^2).[/tex] There are 10000 square centimeters in a square meter:

Total Surface Area in square meters = Total Surface Area in square centimeters / 10000

The gravitational force between two planets of equal mass that were abruptly moved from a distance of 1 million miles to a distance of 2 million miles would be only one-fourth as strong as it had been before.

True. The gravitational force between two masses is inversely proportional to the square of their separation, as stated by Newton's law of universal gravitation.

The gravitational attraction between two planets of the same mass would drop by a factor of 1/22 or 1/4 if the distance between them increased from 1 million miles to 2 million miles.

As a result, the gravitational force would be reduced to 1/4 of what it was before.

Now, we can calculate how many pounds of coffee she bought by dividing the amount she spent by the price rate of coffee by pound.

[tex]\$32.12 \div \dfrac{\$8.03}{1 \text{ lb}}[/tex]

[tex]= \$32.12 \times \dfrac{1 \text{ lb}}{\$8.03}[/tex]

[tex]= \dfrac{32.12}{8.03} \text{ lb}[/tex]

[tex]= \boxed{4 \text{ lb}}[/tex]

So, Ivanna bought 4 pounds of coffee.

Answer:  Ivanna bought 4 pounds of coffee for an amount of$32.12.

Step-by-step explanation:

According to the question,

The reasoning for the third step of the proof would be "Corresponding parts of congruent triangles are congruent." Let's go through the explanation:

1. Given: Quadrilateral ABCD is a rectangle.

2. Given: AB & CD (Opposite sides of a rectangle are equal).

3. To prove: AC & BD.

To prove that AC is equal to BD, we can utilize the property that opposite sides of a rectangle are equal (step 2). In a rectangle, opposite sides are parallel and congruent. Therefore, we have AB || CD and AB = CD.

Now, we need to show that the triangles ABAD and ACDA are congruent, specifically using the SAS (Side-Angle-Side) congruence theorem. The congruence of these triangles will allow us to establish the equality of their corresponding parts, including AC and BD.

4. Given: AD = AD (Reflexive Property of Equality).

5. By step 2, we know AB = CD. Additionally, AD = AD is given (Reflexive Property of Equality).

6. By step 3, ZBAD = ZCDA.

7. Using SAS triangle congruence theorem, we can conclude that triangles ABAD and ACDA are congruent.

Finally, according to the "Corresponding parts of congruent triangles are congruent" property, we can state that AC = BD. This establishes the equality of the diagonals of the rectangle.

The Shares for the other teams are indeed 12, 9, and 6, respectively,  confirms that the solution is correct,there were 8 red balls.

The problem step by step. We are given the following information:

1. The total number of balls is 35.

2. One team takes all the red balls.

3. The remainder (non-red balls) is shared among the other teams in the ratio 4:3:2.

4. The smallest share is 6 balls.

Let's assume the number of red balls is "r". Therefore, the number of non-red balls is 35 - r.

According to the ratio, the shares for the other teams are:

Team 1: (4/9) * (35 - r)

Team 2: (3/9) * (35 - r)

Team 3: (2/9) * (35 - r)

Given that the smallest share is 6 balls, we can set up the equation:

(2/9) * (35 - r) = 6

To solve this equation, we can simplify and solve for "r":

(35 - r) = (9/2) * 6

35 - r = 27

r = 35 - 27

r = 8

Therefore, there were 8 red balls.

To verify the solution, we can calculate the shares for the other teams:

Team 1: (4/9) * (35 - 8) = 4 * 27/9 = 12

Team 2: (3/9) * (35 - 8) = 3 * 27/9 = 9

Team 3: (2/9) * (35 - 8) = 2 * 27/9 = 6

================================================

Explanation:

The standard form for linear equations is Ax+By = C. Anything perpendicular to this would be of the form Bx-Ay = D.

The equation 2x+3y = 9 gives

The perpendicular template goes from Bx-Ay = D to 3x-2y = D.

Plug in the coordinates of (1,-2) to compute D.

3x-2y = D

D = 3x-2y

D = 3*1 - 2*(-2)

D = 7

Therefore, the perpendicular equation is 3x-2y = 7

-----------------------

We need to solve this system

[tex]\begin{cases}2x+3y = 9\\3x - 2y = 7\end{cases}[/tex]

to locate point M.

There are a few methods. I'll use substitution.

Solve the 1st equation for x.

2x+3y = 9

2x = -3y+9

x = (-3y+9)/2

x = -1.5y + 4.5

Then substitute this into the other equation to solve for y.

3x - 2y = 7

3( x ) - 2y = 7

3( -1.5y+4.5 ) - 2y = 7

-4.5y + 13.5 - 2y = 7

-6.5y + 13.5 = 7

-6.5y = 7-13.5

-6.5y = -6.5

y = -6.5/(-6.5)

y = 1

Use that to determine x.

x = -1.5y + 4.5

x = -1.5*1 + 4.5

x = 3

Point M is located at (x,y) = (3, 1)

------------------------

Use the distance formula to find the distance from A(1,-2) to M(3,1)

[tex]A = (x_1,y_1) = (1,-2) \text{ and } M = (x_2, y_2) = (3,1)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-3)^2 + (-2-1)^2}\\\\d = \sqrt{(-2)^2 + (-3)^2}\\\\d = \sqrt{4 + 9}\\\\d = \sqrt{13}\\\\d \approx 3.605551\\\\[/tex]

Answer: B. t= 15; s=5

Step-by-step explanation:

We will create a system of equations.

    t = 3s

Next, we will substitute this value of t into the first equation and solve for s.

    8t + 12s = 180

    8(3s) + 12s = 180

    24s + 12s = 180

    36s = 180

    s = 5 shirts

Lastly, we will substitute this value of s back into t = 3s and solve for t.
