The answer based on debt to assets ratio for east and west company are,

East company debt to assets ratio is equal to 0.44.

West company debt to assets ratio is equal to 0.28.

After comparing both the company debt to assets ratio East company is at higher level of financial risk.

Assets = Liabilities + Equity

For East company,

206,000 =  91,000 + 115,000

Assets = 206,000

liabilities = 91,000

Equity = 115,000

For West company,

603,000 =  169,000 + 434,000

Assets = 603,000

liabilities = 169,000

Equity = 434,000

Debt-to-assets ratio = Total liabilities divided by the total assets.

Debt-to-assets ratio for East

= 91,000 / 206,000

= 0.44

Debt-to-assets ratio for West

= 169,000 / 603,000

There are 120 different ways to form the dance delegation from five pairs of dance partners if two dance partners can never be together on the delegation.

The total number of ways to form the delegation from five pairs of dance partners can be calculated using the combination formula. The combination formula is used to calculate the number of different combinations of n objects taken r at a time without repetition.

In this question, n is the total number of dance partners (5) and r is the number of people on the delegation (4).

Therefore, the calculation is as follows:

total number of ways = nCr

                    = 5C4

                    = 5! / 4!(5-4)!

                    = 5! / 4!1!

                    = 5 x 4 x 3 x 2 x 1 / 4 x 1 x 1

                    = 5 x 4 x 3 x 2

                    = 120

Hence, there are 120 different ways to form the dance delegation from five pairs of dance partners if two dance partners can never be together on the delegation.

The cost to ship a box containing 5 laptops, weighing a total of 11 kg (including the empty box), is $58.90, with a cost of $40.00 for the first 5 kg and $3.15 for each additional kilogram.

The total mass of the packed shipping box can be found by adding the mass of the laptops (5 * 1.65 kg = 8.25 kg) to the mass of the empty box (2.75 kg) for a total mass of 11 kg.

Since the cost to ship the box is $40.00 for the first 5 kg and $3.15 for each additional kilogram over 5 kg, we can split the total mass into two parts: the first 5 kg and the additional weight above 5 kg.

The cost to ship the first 5 kg is $40.00, and the remaining weight is 11 kg - 5 kg = 6 kg.

The cost to ship the additional 6 kg is $3.15 per kilogram, so the total cost to ship the packed box is:

$40.00 + $3.15 * 6 kg = $58.90

Therefore, the cost to ship the packed box is $58.90.

Answer:

31cm

Step-by-step explanation:

14 + 8 + 9 = 31

Make sure to add the cm on the end!

The perimeter of the triangle is 31cm.

The perimeter of the triangle with sides of length 14 cm, 8 cm and 9 cm is 31 cm. This can be calculated by simply adding up the length of each side. To explain, the perimeter of a triangle is the sum of the lengths of all three sides.

In this particular triangle, the length of side 1 is 14 cm, the length of side 2 is 8 cm and the length of side 3 is 9 cm. When we add these three lengths, we get the perimeter of the triangle: 14 cm + 8 cm + 9 cm = 31 cm.

In general, to calculate the perimeter of any triangle, we first have to identify the lengths of all three sides. Then, we simply add these lengths together to get the perimeter.

For example, if the triangle had sides of lengths 4 cm, 5 cm and 6 cm, then the perimeter would be 4 cm + 5 cm + 6 cm = 15 cm.

In conclusion, the perimeter of any triangle can be calculated by adding together the length of each side. In the case of the particular triangle in question, the perimeter is 31 cm.

The correct order of the steps of eukaryotic DNA replication from when a germ cell enters gap 1 (G1) phase to the cell cycle termination is : G1-> S Phase ->G2 ->Mitosis ->Cytokinesis ->Cell cycle termination

Step-by-step explanation:

The correct order of the steps of eukaryotic DNA replication from when a germ cell enters gap 1 (G1) phase to the cell cycle termination is as follows:

Step 1: G1 phase - During this phase, the germ cell is growing and preparing for DNA synthesis.

Step 2: S phase - DNA replication occurs during this phase. The chromosomes duplicate to form two identical chromatids, which remain attached at the centromere.

Step 3: G2 phase - During this phase, the cell checks for any errors in DNA replication and prepares for cell division.

Step 4: Mitosis - The cell divides its replicated DNA and organelles into two identical daughter cells. This process ensures that each daughter cell has the same amount of genetic material as the parent cell.

Step 5: Cytokinesis - The cytoplasm divides, creating two identical daughter cells.

Step 6: Cell cycle termination: After successful completion of mitosis and cytokinesis, the cell cycle is terminated, and the daughter cells may enter a new cycle or enter a non-dividing state (G0 phase).

Esther missed including the surface area of the square sides of the pyramid. The correct surface area is found by adding the surface area of the four triangular faces, base, and sides. The total surface area is 104cm².

Esther's error was that she only considered the surface area of the triangular faces and the base of the pyramid. She failed to include the surface area of the pyramid's square sides.

To find the correct surface area of the pyramid, we need to add the surface area of the four triangular faces and the surface area of the square base and sides. The surface area of the square base is 4² = 16cm², and the surface area of each triangular face is (1/2)bh = (1/2)(4)(7) = 14cm². The surface area of each square side is 4 x 4 = 16cm².

Therefore, the correct surface area of the square pyramid is:

4 x 14cm² (for the four triangular faces) + 16cm² (for the base) + 4 x 16cm² (for the four square sides) = 104cm².

Step-by-step explanation:

The circle is open so seven is not included which eliminates the second and fourth choice.

x<7 means x is less than seven which is wrong.

x> means x is greater than seven.

Answer:

x > 7

Step-by-step explanation:

We see that the arrow is going to the right, signaling greater than.

We know that it is not greater than or equal to, since the dot is not shaded.

So, the answer is x > 7.

a) General solution of the system is (x, y, z) = (2, 0, 1).

b) There are no multiple solutions, and we cannot find two specific solutions.

The given system of linear equations is:
1) x - y + z = 3
2) 3x + 2z = 7
3) x - 4y + 2z = 5

The reduced matrix for this system is:
1 0 1
0 1 0
0 0 1

Using the reduced matrix, we can rewrite the system of linear equations as:
1) x + z = 3
2) y = 0
3) z = 1

Now we can solve the system step by step:

From equation (3), we know that z = 1.

Next, we can use the value of z in equation (1) to find x:
x + 1 = 3
x = 3 - 1
x = 2

Finally, from equation (2), we know that y = 0.

So, the general solution of the system is (x, y, z) = (2, 0, 1).

(b) Since there is only one solution to this system, there are no multiple solutions, and we cannot find two specific solutions.

We are given two equations as f(x) = [tex]\frac{-1}{2}[/tex]x + 6 and f(x) = √x - 4.

Now, on equating both the equations, we get

⇒ [tex]\frac{-1}{2}[/tex]x + 6 = √x - 4

On squaring both sides, we get,

⇒ [tex](\frac{-1}{2}x + 6)^{2}[/tex]= x - 4

⇒ [tex]\frac{1}{4}x^{2}[/tex] + 36 - 6x = x - 4

⇒ [tex]\frac{1}{4}x^{2}[/tex] + 40 = 7x

⇒ [tex]\frac{1}{4}x^{2}[/tex] -7x + 40 = 0

⇒ [tex]x^{2}[/tex] -28x + 160 = 0

⇒ x = 20 , 8

For point of intersection, we will substitute x = 20 in both the equations.

So, we get

⇒ f(x) = [tex]\frac{-1}{2}[/tex] (20) + 6

⇒ f(x) = -10 + 6

⇒ f(x) = -4

Similarly,

⇒ f(x) = √20 - 4

The high school dropout rate in the United States is greater than 25 percent. C. Wright Mills would classify this situation as a societal issue.

This is because societal issues are matters of public concern that affect large numbers of people and require collective action to resolve. The high school dropout rate in the United States is an example of a societal issue because it has widespread implications for both individuals and society as a whole.

According to Mills, a societal issue is one that cannot be attributed solely to the actions of individuals. Instead, it is the result of social structures and processes that operate at a broader level.

For example, the high school dropout rate in the United States is influenced by a variety of factors such as poverty, race, and family background. These factors are not solely determined by the actions of individual students but are instead shaped by broader social forces such as economic inequality and institutional racism.

To address the high school dropout rate, therefore, requires collective action at the societal level. This may involve policy changes, community-based initiatives, or other forms of collective action aimed at addressing the underlying social factors that contribute to the problem.

The ratio of the heights is 5, the ratio of the surface areas is 25, and the ratio of the volumes is 125

Step-by-step explanation:

We can use the fact that similar pyramids have the same shape, but possibly different sizes. Let's denote the height of pyramid a by h_a, the height of pyramid b by h_b, and the scale factor between the two pyramids by k. Then, we have:

The ratio of the heights is k, since the height is scaled up by the same factor as the base length. That is, k = h_b / h_a.

The ratio of the surface areas is k^2, since the surface area is proportional to the square of the base length and the height. That is, k^2 = (side length of b / side length of a)^2 = (25 / 5)^2 = 5^2 = 25.

The ratio of the volumes is k^3, since the volume is proportional to the cube of the base length and the height. That is, k^3 = (side length of b / side length of a)^3 = (25 / 5)^3 = 5^3 = 125.

The exact dimensions (in inches) of the cylindrical mailing tube that may be mailed using the postal service is 7 inches radius and a length of 14 inches.

To find the maximum volume of the mailing tube, maximize the function:

V = πr²L

subject to the constraint:

C = 2πr + L = 84

where C is the girth.

Using Lagrange multipliers, we need to solve the system of equations:

∇V = λ∇C

2πrL = λ(2π)

πr² = λ

2πr + L = 84

Taking the ratio of the first two equations:

L = 2r

Substituting this into the third equation:

4πr + 2r = 84

Simplifying:

r = 7

Substituting this into the equation L = 2r:

L = 14

From the same starting point, two cyclists ride in different directions. The speed of one cyclist is twice that of the other. They will be 72 miles apart in 2 hours. The rate of each cyclist is 12 miles per hour and 24 miles per hour

Let’s call the rate of the slower cyclist “r”. Then, according to the problem, the rate of the faster cyclist is “2r”.

We can use the formula distance = rate x time to set up two equations, one for the distance traveled by the slower cyclist and one for the distance traveled by the faster cyclist. The sum of these distances is the total distance they are apart after 2 hours, which we know is 72 miles:

2r x 2+r x 2=72

Simplifying this equation, we get:

4r+2r=72

Combining like terms, we get:

6r=72

Dividing both sides by 6, we get:

R=12

So the rate of the slower cyclist is 12 miles per hour. Using the fact that the faster cyclist rides at twice the rate of the slower cyclist, we can find the rate of the faster cyclist:

2r=2 x 12=24

So the rate of the faster cyclist is 24 miles per hour.

Therefore, the two cyclists ride at rates of 12 miles per hour and 24 miles per hour, respectively.
