Step-by-step explanation:
Mia's food delivery service is $0.65 per mile. She also charges an $8 fee for gas needed to get there. Write an expression to show the cost of her services per mile, m.
The cost of Mia's food delivery service per mile is $8.65.
To calculate the cost of Mia's food delivery service per mile, we need to consider two components: the cost per mile and the fixed gas fee.
Let's define the cost per mile as 'C' and the fixed gas fee as 'F'. Given that Mia's food delivery service is $0.65 per mile and she charges an $8 fee for gas, the expression for the cost of her services per mile, 'm', can be written as follows:
m = C + F
Substituting the given values into the expression:
m = $0.65 per mile + $8
Simplifying, we have:
m = $0.65 + $8
Combining the terms, the expression for the cost of Mia's services per mile is:
m = $8.65
Therefore, the cost of Mia's food delivery service per mile is $8.65.

The volume of a box, a rectangular prism, is represented by the function f(x) = x3 5x2 – 8x – 12. the length of the box is (x 6), and the width is (x – 2). find the expression representing the height of the box. x – 1 x – 5 x 1 x – 12
The expression representing the height of the box is the difference between the length and width of the box, which is equal to x subtracting two, or x – 1.
The expression representing the height of the box can be determined by subtracting the width of the box from the length. The length of the box is x 6, and the width is x – 2. To calculate the height, we subtract the width from the length: x – (x – 2) = x – x + 2 = 2. Therefore, the expression representing the height of the box is x – 1. This indicates that the height of the box is equal to the length of the box minus one. This calculation can be applied to any rectangular prism to calculate the height.The volume of the box is represented by the function f(x) = x3 5x2 – 8x – 12. To calculate the volume, we can substitute the length and width into the function:
f(x) = (x – 6)(x – 2)(x – 1) = x3 – 8x2 + 11x – 12.
Therefore, the volume of the box is x3 – 8x2 + 11x – 12.

Calculate the average number of cars in the system. (Select the appropriate range in which your answer falls.]
11. The appropriate range for the partial labor productivity is more than 1.0 but less than or equal to 2.0.
12. The appropriate range for the average number of cars in the system is more than 0.5 but less than or equal to 1.0.
Question 11: To calculate the partial labor productivity (units/$), we need to divide the total output (500 units) by the labor cost ($350).
Partial labor productivity = Total output / Labor cost
= 500 units / $350
≈ 1.43 units/$
Based on the given options, the answer falls in the range of more than 1.0 but less than or equal to 2.0.
Therefore, the appropriate range for the partial labor productivity is more than 1.0 but less than or equal to 2.0.
Question 12: To calculate the average number of cars in the system, we can use Little's Law, which states that the average number of cars in the system (L) is equal to the arrival rate (λ) divided by the service rate (μ).
Average number of cars in the system (L) = Arrival rate (λ) / Service rate (μ)
Arrival rate (λ) = 21 cars per hour
Service rate (μ) = 27 cars per hour
Average number of cars in the system (L) = 21 cars per hour / 27 cars per hour
≈ 0.78 cars
Based on the given options, the answer falls in the range of 0.5 to 1.0.
Therefore, the appropriate range for the average number of cars in the system is more than 0.5 but less than or equal to 1.0.

Therefore, the function f(x) that satisfies the initial value problem is: f(x) = 3x.
To find the function f(x) described by the given initial value problem, we integrate the second derivative of f(x) twice and apply the initial conditions.
Given: f′′(x) = 0, f′(1) = 3, f(1) = 3
Integrating the second derivative of f(x) gives us the first derivative:
f′(x) = C₁
Integrating the first derivative gives us the function f(x):
f(x) = C₁x + C₂
Applying the initial condition f′(1) = 3:
f′(1) = C₁ = 3
Substituting C₁ = 3 into the equation for f(x):
f(x) = 3x + C₂
Applying the initial condition f(1) = 3:
f(1) = 3(1) + C₂ = 3

If person A and person B have equal positive amounts of goods X and Y and person A values good X more than good Y and person B values good Y more than good X, there are mutually beneficial trades available.
Mutually beneficial trades are the kind of trades that benefit both parties in a trade agreement. A mutually beneficial trade occurs when two countries or individuals trade and both benefit from the transaction. In the case where person A and person B have equal positive amounts of goods X and Y and person A values good X more than good Y and person B values good Y more than good X, there are mutually beneficial trades available. This is because person A would be more willing to trade his good Y for Person B’s good X since person A values good X more than good Y and person B would be more willing to trade his good X for person A’s good Y since person B values good Y more than good X. In this way, both parties would benefit from the transaction because they would be trading the goods they value less for the ones they value more.

Find the surface area of the figure. Hint: the surface area from the missing prism inside the prism must be ADDED!
To find the surface area of the figure, we need to consider the individual surfaces and add them together.
First, let's identify the surfaces of the figure:
The lateral surface area of the larger prism (excluding the base)
The two bases of the larger prism
The lateral surface area of the smaller prism (excluding the base)
The two bases of the smaller prism
The lateral surface area of a prism is given by the formula: perimeter of the base multiplied by the height.
The bases of the prisms are rectangles, so their areas can be calculated by multiplying the length by the width.
To find the missing prism's surface area, we need to consider that it is a smaller prism nested inside the larger prism. The lateral surface area and bases of the missing prism should also be included.
Once we have calculated the individual surface areas, we add them together to find the total surface area of the figure.
Without specific measurements or dimensions of the figure, it is not possible to provide a numerical answer. Please provide the necessary measurements or dimensions to calculate the surface area.

If A is a closed subset of a metric space X, show that any map f:A → E" can be extended over X.
The answer to your question is that any map f:A → E can be extended over X if A is a closed subset of a metric space X.
the reason for this is because a closed subset of a metric space is complete, meaning that any Cauchy sequence in A converges to a point in A. Additionally, any point in X not in A is at a positive distance from A, allowing us to construct a continuous function that extends f to X.
However, this may require a long answer to fully prove and understand, including concepts such as uniform continuity and the Stone-Weierstrass theorem.

A city planner wants to build a road perpendicular to D Street. What should be the slope of the new road?
The slope of the new road is zero.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Take points from the Graph (5, 0) and (5, 4).
Slope of a line = m = tanθ
where θ is the angle made by the line with the x−axis.
For a line parallel to y−axis ,θ= π/2.
∴m = tan π/2 = undefined
The new road will therefore have 0° of inclination if it is perpendicular to D street because if they are perpendicular and D street is vertical, the new road is level and has 0° of inclination.
An horizontal line now has zero slope.
The new road has a zero slope as a result.

a teacher conducted a random survey of his students and found that 33% did not have a pet. to the nearest whole number, how many students would have a pet out of a population of 134? gaumath
The number of students who would have a pet out of a population of 134 is equal to 90.
Percent of students did not have pet = 33%
Total number of students = 134
Number of students who do not have a pet
= 33% × 134
= 0.33 × 134
= 44.22
Since we cannot have a fraction of a student.
Round 44.22 to the nearest whole number which is 44.
This means that 44 out of the 134 students surveyed did not have a pet.
The number of students who have a pet
= subtract the number of students who do not have a pet from the total number of students.
⇒ Number of students who have a pet = 134 - 44
⇒ Number of students who have a pet = 90
Therefore, approximately 90 students out of a population of 134 have a pet.

The value of R expressed in standard form to an appropriate degree of accuracy as required in the task content is; 2.447 × 10⁶.
What is the value of R expressed in standard form to an appropriate degree of accuracy as required in the task content?It follows from the task content that the equation given in the task content for R is;
R = x²/y.
Additionally, the values of x and y are given as; 3.8 × 10⁵ and 5.9 × 10⁴ respectively.
On this note, it follows from substitution that the value of R can be determined as follows;
R = (3.8 × 10⁵)²/(5.9 × 10⁴)
R = (3.8)² × (10⁵)²/5.9 × 10⁴
R = 14.44 × 10¹⁰/5.9 × 10⁴
It therefore follows from the quotient of powers law that we have;
R = (14.44/5.9) × 10⁶
R = 2.447 × 10⁶.

The probability of drawing a 7 followed by a 10 is (4/52) x (4/51) = 0.006 or 0.6%.
To calculate the probability of drawing a 7 first and then a 10 from a standard 52-card deck, you need to consider the number of 7s and 10s in the deck and the total number of cards.
There are 4 sevens and 4 tens in the deck. The probability of drawing a 7 first is 4/52 (since there are 4 sevens and 52 cards in total). After drawing a 7, there are now 51 cards left in the deck. The probability of drawing a 10 next is 4/51 (since there are still 4 tens but now only 51 cards).
