The equation to get m for a given value of g is:

(1800 - 10g)/45 = m

Ok, here we have the equation:

1,800 = 10g + 45m

We want to find an equation so we can find the value of m for a given value of g, then, we need to isolate m in the above equation:

First, we can subtract 10g in both sides, so we get:

1,800 - 10g = 45m

Now we can divide both sides by 45, so we get:

(1800 - 10g)/45 = m

That is the equation that we can use to find the value of m, we just need to evaluate it in the given value of g.

The required cycle-time is approximately 57.6 seconds.

To find the required cycle time, we need to divide the total available time by the number of units to be produced.

Total available time: 16 hours = 16 * 60 minutes = 960 minutes = 960 * 60 seconds = 57,600 seconds

Number of units to be produced: 1,000 units

Required cycle time: Total available time / Number of units

Cycle time = 57,600 seconds / 1,000 units

Cycle time ≈ 57.6 seconds

Therefore, the required cycle time is approximately 57.6 seconds.

Answer:

It will take 1.19 seconds for the ball to hit the ground if no other players touch it

Step-by-step explanation:

The height of the ball after t seconds is given by the following equation:

\(h(t) = -4.9t^{2} + 5t + 1\)

How long will it take the ball to hit the ground if no other players touch it?

This is t when h(t) = 0. So

\(-4.9t^{2} + 5t + 1 = 0\)

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

\(ax^{2} + bx + c, a\neq0\).

This polynomial has roots \(x_{1}, x_{2}\) such that \(ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})\), given by the following formulas:

\(x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}\)

\(x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}\)

\(\bigtriangleup = b^{2} - 4ac\)

In this question:

\(-4.9t^{2} + 5t + 1 = 0\)

So \(a = -4.9, b = 5, c = 1\)

So

\(\bigtriangleup = 5^{2} - 4*4.9*1 = 44.6\)

\(t_{1} = \frac{-5 + \sqrt{44.6}}{2*(-4.9)} = -0.17\)

\(t_{2} = \frac{-5 - \sqrt{44.6}{2*(-4.9)}  = 1.19\)

Since we want a time measure, the answer cannot be negative.

It will take 1.19 seconds for the ball to hit the ground if no other players touch it

After considering the given data we conclude that project should be rejected under the condition that appropriate cost of capital is 12 percent.

To place the Modified Internal Rate of Return (MIRR) statistic for Project I with a cost of capital of 12 percent, we can use the following steps:
Evaluate the present value of the negative cash flow at time 0, which is -$12,500.
Evaluate the future value of the positive cash flows at the end of the project, which is $2,270 + $2,750 = $5,020.
Evaluate the present value of the future value of the positive cash flows using the reinvestment rate, which is the cost of capital of 12 percent. This is evaluated as \($5,020 / (1 + 0.12)^4 = 3,052.56\).
Evaluate the MIRR using the formula: \(MIRR = (FVCF / PVCF)^{(1/n)} - 1\),
Here, FVCF is the future value of the positive cash flows discounted at the reinvestment rate, PVCF is the present value of the negative cash flow discounted at the financing rate, and n is the number of periods.
Staging in the values, we get \(MIRR = ($3,052.56 / -$12,500)^{(1/4)} - 1 = -0.0903\), or -9.03%.
Therefore the MIRR is negative, the project should be rejected as it is not expected to generate a positive return at the cost of capital of 12 percent.
Hence , the answer is to reject the project

This equation shows that the cost of downloading songs is proportional to the number of songs that are downloaded.

The cost of something typically depends on the type of item, its quality, and the quantity desired. Prices can vary greatly depending on these factors. It is best to contact the seller for an accurate cost.

The cost for each song is 0.41 dollars, plus an additional 0.32 dollars for the transaction fee. As the number of songs increases, the total cost of the downloads increases. This is because the cost of each song is multiplied by the number of songs being downloaded, plus the additional transaction fee.

The cost of downloading songs is based on a variety of factors, including the format of the song, the artist, and the country it is being downloaded from. The cost of each song is also determined by the terms and conditions of the service provider. Additionally, taxes and other applicable fees may be applied to the total cost of the download.

This proportional equation illustrates how the cost of downloading songs is determined. By understanding the equation and the factors that influence the cost of the songs, consumers can make informed decisions when choosing which music to download.

Answer:

Kailey flipping heads: 3/4 as a fraction, 0.75 as a decimal, and 75% as a percent.

Olivia flipping tails: 9/20 as a fraction, 0.45 as a decimal, and 45% as a percent.

Step-by-step explanation:

Kailey flipped heads 15 times and tails 5 times.

First, find the total amount of times that Kailey flipped the coin.

15+5=20

Kailey flipped the coin 20 times.

Out of those 20 times, she flipped heads 15 times. We can rewrite this as:

\(\frac{15}{20}\)

and simplify it:

\(\frac{3}{4}\)

3/4 as a decimal is 0.75, and to find the percentage, simply multiply the decimal form by 100.

We can find that 3/4 as a percentage is 75%.

So, the probability of Kailey flipping heads is:

3/4 as a fraction, 0.75 as a decimal, and 75% as a percent.

Olivia flipped heads 11 times and tails 9 times.

Let's find how many times she flipped the coin.

11+9=20

Olivia flipped the coin 20 times.

Out of 20 times, Olivia flipped tails 9 times.

This can be rewritten as:

\(\frac{9}{20}\)

This fraction is already in simplest form.

To find what 9/20 is as a decimal, divide 9 by 20. You'll get 0.45.

Now, multiply 0.45 by 100 to find the percent. You'll get 45%.

So, the probability of Olivia flipping tails is:

9/20 as a fraction, 0.45 as a decimal, and 45% as a percent.

Step-by-step explanation:

There are 43,200 number of ways to arrange the letters in UNIVERSALLY so that no two vowels occur consecutively and the consonants appear in alphabetical order.

To find the number of ways to arrange the letters in UNIVERSALLY so that no two vowels occur consecutively and the consonants appear in alphabetical order, follow these steps:

1. Identify the vowels and consonants: Vowels are U, I, E, A, and Y; consonants are N, R, S, S, L, and L.

2. Arrange the consonants in alphabetical order: L, L, N, R, S, S.

3. Count the number of positions available for placing the vowels: There are 7 positions available for the vowels (between the consonants and at the beginning and the end of the word), which are _ L _ L _ N _ R _ S _ S _.

4. Count the permutations of the vowels: There are 5 vowels with the letters U, I, E, A, and Y occurring once. So there are 5! = 120 permutations.

5. Consider the consonants with repeating letters: Since there are two Ls and two Ss, we must divide the total permutations by the product of the repetitions (2! for L and 2! for S). Therefore, there are 6!/(2!*2!) = 360 arrangements for consonants.

6. Combine the permutations of vowels and consonants: To find the total number of ways to arrange the letters, multiply the permutations of vowels (120) by the arrangements for consonants (360).

120 * 360 = 43,200

So, there are 43,200 ways to arrange the letters in UNIVERSALLY so that no two vowels occur consecutively and the consonants appear in alphabetical order.

If you are asked to evaluate the expression 3(z + 9), you can simplify it using the distributive property to get the answer of 3z + 27.

What is algebra?

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas. It involves the study of variables, expressions, equations, and functions.

The distributive property is a fundamental rule in algebra that allows you to simplify expressions that contain parentheses. It says that when you multiply a number by a sum (in this case, z + 9), you can distribute the multiplication to each term inside the parentheses. This means you multiply the first term in the parentheses (z) by the number outside the parentheses (3), and then you multiply the second term (9) by the same number (3).

So, when we apply the distributive property to the expression 3(z + 9), we get:

3(z + 9) = 3z + 3(9)

We can then simplify 3(9) by multiplying 3 and 9 together to get:

3(z + 9) = 3z + 27

Therefore, this means that 3(z + 9) is equivalent to 3z + 27.

Therefore, if you are asked to evaluate the expression 3(z + 9), you can simplify it using the distributive property to get the answer of 3z + 27.
