We are asked to convert 2.5 years into hours.

Step 1:

There are 365 days in a year so 2.5 years will have

Step 2:

There are 24 hours in a day so 912.5 days will have

Therefore, 2.5 years will have 21900 hours.

The value of x and y for the first set of equations is -2 and 2 respectively, while the value of x and y for the next set of equations is 4 and 5 respectively.

We have equations

-x + y = 4                               [1]

x + 3y = 4                             [2]

Here we see that we can eliminate x by simply adding [1] and [2] up
we get

4y = 8

or, y = 2

Putting this equation [1] we get

-x + 2 = 4

or, -x = 2

or, x = -2

The next set of equations is

5x+6y=50                             [3]

x−6y=−26                             [4]

here we can eliminate y. hence we get

6x = 24

or, x = 4

putting this value in equation [3] we get

4 - 6y = -26

or, 6y = 4 + 26

or, y = 30/6

or, y = 5

No, Savannah is incorrect. Doubling the length, width, and height of a right rectangular prism will not double its surface area.

Surface area is the total area of an object's exposed faces, including any external surface area. It is a measure of the size of a surface and is usually expressed in square units such as square meters or square centimeters. Surface area is a two-dimensional measurement, since it only takes into account the area of a surface, and not its thickness or volume.

The surface area of a right rectangular prism is calculated by multiplying the length by the width and then multiplying that number by two and adding the two products together.

For example, the surface area of a right rectangular prism with a length of 15 cm, a width of 10 cm, and a height of 5 cm is calculated as follows:

Surface area = (15 cm * 10 cm) + (15 cm * 5 cm) = 150 cm2 + 75 cm2 = 225 cm2

Doubling the length, width, and height of this right rectangular prism would give us a prism with a length of 30 cm, a width of 20 cm, and a height of 10 cm. The surface area of this new prism would be calculated as follows:

Surface area = (30 cm * 20 cm) + (30 cm * 10 cm) = 600 cm2 + 300 cm2 = 900 cm2

As you can see, doubling the length, width, and height of the right rectangular prism does not double its surface area - the surface area has increased by four times (900 cm2/225 cm2 = 4).

In conclusion, doubling the length, width, and height of a right rectangular prism does not double its surface area; rather, it increases the surface area by a factor of four.

Airplane 1 had the fastest rate of descent during its landing.

To compare the rates of descent of the two airplanes, we need to convert both rates to a common unit of measurement. Let's convert both rates to feet per minute (ft/min) to make the comparison easier.

Airplane 1 had a rate of descent of -130 ft/s, which is equivalent to:

-130 ft/s × 60 s/min = -7800 ft/min

Airplane 2 had a rate of descent of -97/8 ft/s, which is equivalent to:

(-97/8) ft/s × 60 s/min = -729.375 ft/min

Comparing these two rates, we can see that Airplane 1 had the faster rate of descent during its landing:

-7800 ft/min (Airplane 1) > -729.375 ft/min (Airplane 2)

Therefore, Airplane 1 had the fastest rate of descent during its landing.

Answer:

y=-3

Step-by-step explanation:

just tryt if it is correct.

The rational function can be written as: f(x) = -3(x - 4)(x + 2) / ((x - 1)(x + 4))

To write an equation for a rational function with the given characteristics.

1. Vertical Asymptotes: We have vertical asymptotes at x = -1 and x = 4. This means that the function cannot take these values as inputs.

We can represent this by having factors of (x - 1) and (x + 4) in the denominator of our rational function.

2. x-intercepts: We know that the function passes through the points (-4, 0) and (2, 0). This means that the function has factors of (x - 4) and (x + 1) in the numerator.

3. Horizontal Asymptote: We are given that the horizontal asymptote is y = 4.

This means that as x approaches positive or negative infinity, the function approaches y = -3.

We can represent this by having a constant term of 4 in the numerator.

Combining all these pieces, the equation for the rational function can be written as: f(x) = -3(x - 4)(x + 2) / ((x - 1)(x + 4))

This equation satisfies the given characteristics: vertical asymptotes at x = 1 and x = 4, x-intercepts at (4, 0) and (-1, 0), and a horizontal asymptote at y = 4.

Step-by-step explanation:

The graph of the system of the inequalities is attached.

To graph the inequalities y < -x - 4 and y ≥ (3/5)x + 4, we can start by graphing the corresponding equations and then shade the appropriate regions based on the inequality signs.

Let's begin with the equation y = -x - 4:

Choose a range of x-values to plot.

For simplicity, let's use x-values from -10 to 10.

Substitute different x-values into the equation to find corresponding y-values.

For example:

When x = -10, y = -(-10) - 4 = 10 - 4 = 6.

When x = 0, y = -(0) - 4 = -4.

When x = 10, y = -(10) - 4 = -10 - 4 = -14.

Plot these points on the coordinate plane and draw a straight line passing through them.

This line represents the equation y = -x - 4.

Next, let's graph the equation y = (3/5)x + 4:

Again, choose a range of x-values to plot. Let's use the same range of -10 to 10.

Substitute different x-values into the equation to find corresponding y-values. For example:

When x = -10, y = (3/5)(-10) + 4 = -6 + 4 = -2.

When x = 0, y = (3/5)(0) + 4 = 0 + 4 = 4.

When x = 10, y = (3/5)(10) + 4 = 6 + 4 = 10.

Plot these points on the coordinate plane and draw a straight line passing through them.

This line represents the equation y = (3/5)x + 4.

Now, let's shade the regions based on the inequalities:

For y < -x - 4, we need to shade the region below the line y = -x - 4.

For y ≥ (3/5)x + 4, we need to shade the region above or on the line y = (3/5)x + 4.

Hence, the region where the shaded regions overlap represents the solution to both inequalities.

Answer:

$1300

Step-by-step explanation:

λ = average = 2 per day, Y denotes the number of breakdowns per day,

But E(Y) = λ, E[Y(Y - 1)] = λ²

E(Y²) = E[Y(Y - 1)] + E(Y), hence:

E(Y²) = λ² + λ

The daily revenue is R=1600−50Y². The expected daily revenue for the extruder E(R) is:

E(R) = E(1600−50Y²) = 1600 - 50E(Y²)

E(R) = 1600 - 50(λ² + λ)

Substituting:

E(R) = 1600 - 50(2² + 2)

E(R) = 1600 - 300 = 1300

E(R) = $1300

What is Percentage?

To compute a percentage, divide the value by the entire amount and multiply the result by 100. A percentage is a quantity or ratio that is stated as a fraction of one hundred. The percent sign, "%," is frequently used to represent it.

First, we need to calculate the average of Maureen's three highest salaries:

Average = (107,000 + 107,800 + 108,198) / 3

Average = 322,998 / 3

Average = 107,666

Next, we need to calculate 1.56% of this average:

Percentage = 1.56% * 107,666

Percentage = 1,667.84

Finally, we multiply this percentage by the number of years worked to find the pension:

Pension = 30 * 1,667.84

Pension = 50,035.20

So, Maureen's pension would be $50,035.20.

The average daily balance of the credit card for the October 1 - October 31 billing period is $9,645.16.

To calculate the average daily balance of the credit card for the October 1 - October 31 billing period, we need to find the sum of the daily balances for each day in the billing period, and then divide that sum by the number of days in the billing period.

We can calculate the daily balance for each day by taking the closing balance from the previous day, and then adding or subtracting any transactions that occurred on that day.

Using this method, we can calculate the daily balances for each day in the billing period as follows:

Day 2-10: Daily balance = $10,000

Day 11-20: Daily balance = $8,000

Day 21-30: Daily balance = $9,500

Day 31: Daily balance = $10,500

To calculate the average daily balance, we need to find the sum of the daily balances for each day in the billing period, and then divide by the number of days in the billing period:

Average daily balance = (10,000 x 9) + (8,000 x 10) + (9,500 x 10) + (10,500 x 1) / 31

= 298,500 / 31

The Volume of each bead is approximately 1.767 mm^3 when rounded to the nearest tenth.

The volume of each bead, the volume of a sphere using its diameter. The formula for the volume of a sphere is given by:

V = (4/3) * π * r^3

where V is the volume and r is the radius of the sphere.

Given that the diameter of each bead is 1.5 millimeters, we can calculate the radius as half of the diameter:

r = 1.5 mm / 2 = 0.75 mm

Now, we can substitute the value of the radius into the volume formula:

V = (4/3) * π * (0.75 mm)^3

Using the value of π ≈ 3.14 and performing the calculations:

V ≈ (4/3) * 3.14 * (0.75 mm)^3

V ≈ (4/3) * 3.14 * 0.421875 mm^3

V ≈ 1.767 mm^3 (rounded to the nearest tenth)

the volume of each bead is approximately 1.767 mm^3 when rounded to the nearest tenth.
