A rental truck company charges a flat fee of $30 to rent a truck in addition to $0.25 per miles how much would it cost to rent a van for 80 miles

Answer:

3600

Step-by-step explanation:so it is easiest to do one persons costs then just multiply it by 4 to get the cost of 4 people. so first for one person..... (their travel is) 130 + (hotel x 7 days) 60 x 7 + (spending money) 350 =900 . now multiply this by 4 = 3600

Let's start off by working out the cost for one person. This person has to spend 130 pounds on travel and have 350 pounds of spending money. So far that is 130+350 = 480 pounds. Then it says the hotel costs 60 pounds per day. At 7 days, it will cost one person 7*60 = 420 pounds. This adds onto the 480 to get 420+480 = 900.

Therefore, each person will need 900 pounds to go on a 7 day trip. If we had 4 people going, then 4*900 = 3600 pounds is needed total.

2^6 x 3^3 and 12^3

Step-by-step explanation:

First, solve

6^3 x 2^6/2^3

216 x 64/8

13824/8 = 1728

lets solve for the answers

6^3 = 216

Therefore, 6^3 is not an answer

2^6 x 3^3= 64 x 27 = 1728

because both expressions are equal to 1728, this is an answer. this answer can also eliminate 2^3 x 3^3 because it has a lower exponent than the answer that is equal to 1728. therefore, the value of it must be smaller than 1728

12^3 = 1728

This answer is correct, because both values are equal to each other, meaning that 12^6 is larger than 1728  

Therefore, your answers will be 2^6 x 3^3 and 12^3

The equation of the parabola with vertex at the origin and the given directrix y = -1/3 is:
\(x^2 = 4/3y\).

To write the equation of a parabola with vertex at the origin and the given directrix, we can use the standard form of the equation for a parabola with vertical axis of symmetry:

\((x - h)^2 = 4p(y - k)\)

where (h, k) represents the vertex coordinates and p represents the distance from the vertex to the directrix.
In this case, the vertex is at the origin (0, 0), and the directrix is y = -1/3.
1: Determine the value of p.
Since the directrix is below the vertex, the value of p is positive and represents the distance from the vertex to the directrix. In this case, p = 1/3.
2: Substitute the vertex and the value of p into the equation.
\((x - 0)^2 = 4(1/3)(y - 0)\)
Simplifying this equation, we get:

The percent yield is calculated as the ratio of the actual yield to the theoretical yield, multiplied by 100.

Percent yield is a measure of how efficient a chemical reaction or process is in producing the desired product.

The formula for percent yield is:

Percent Yield = (Actual Yield / Theoretical Yield) * 100

The actual yield is the amount of product obtained from the reaction or process, typically measured in grams or moles. It represents the actual amount of product obtained in the laboratory.

The theoretical yield, on the other hand, is the maximum amount of product that can be obtained based on stoichiometry and other factors. It is calculated using balanced chemical equations and the starting amounts of reactants.

By dividing the actual yield by the theoretical yield and multiplying by 100, we get the percent yield, which is expressed as a percentage.

This value provides insight into the efficiency of the reaction or process, with a higher percent yield indicating a more efficient conversion of reactants into products.

The values of x and y in the given system of equations are x = 4.00 and y = 5.00. These values are obtained by solving the system using the method of substitution.

The given system of linear equations is:

0.50x + 0.20y = 3.00 ...(Equation 1)

x + y = 9.00 ...(Equation 2)

To solve this system of equations, we can use the method of substitution or elimination. Let's solve it using the method of substitution:

From Equation 2, we can express x in terms of y:

x = 9.00 - y

Substituting this expression for x in Equation 1, we have:

0.50(9.00 - y) + 0.20y = 3.00

Expanding and simplifying:

4.50 - 0.50y + 0.20y = 3.00

-0.30y = -1.50

Dividing both sides by -0.30:

y = -1.50 / -0.30

y = 5.00

Now, substitute this value of y back into Equation 2 to find x:

x + 5.00 = 9.00

x = 9.00 - 5.00

x = 4.00

Therefore, the values of x and y in the given system of equations are x = 4.00 and y = 5.00.

Answer:

Step-by-step explanation:

Given that the total sales of a company in millions of dollars t months from now is given by S(t) = 41.04785t. We need to find the values of S(6), S(12), and S(42) and interpret the values of S(11) and S(11) - S(0).

a) To find S(6), we substitute t = 6 in the given formula, S(t) = 41.04785t.

Therefore, we have S(6) = 41.04785(6) = 246.2871 million dollars.

Hence, S(6) = 246.2871 million dollars.

b) To find S(12), we substitute t = 12 in the given formula, S(t) = 41.04785t.

Therefore, we have S(12) = 41.04785(12) = 492.5742 million dollars.

Hence, S(12) = 492.5742 million dollars.

c) To find S(42), we substitute t = 42 in the given formula, S(t) = 41.04785t.

Therefore, we have S(42) = 41.04785(42) = 1724.0807 million dollars. Rounded off to two decimal places, S(42) = 1724.08 million dollars.

d) S(11) represents the total sales of the company in 11 months from now and S(11) - S(0) represents the total increase in sales of the company between now and 11 months from now.

Substituting t = 11 in the given formula, S(t) = 41.04785t, we have S(11) = 41.04785(11) = 451.52635 million dollars.

Hence, S(11) = 451.52635 million dollars.

Substituting t = 11 and t = 0 in the given formula, S(t) = 41.04785t, we haveS(11) - S(0) = 41.04785(11) - 41.04785(0) = 451.52635 - 0 = 451.52635 million dollars.

Hence, S(11) - S(0) = 451.52635 million dollars.

The true statements about the dilation of segment AB are:

The dilation is an enlargement.

Point O is the center of dilation.

The scale factor is 3.

The scale factor is 9.

Dilation is a geometric transformation that alters the size of a figure while maintaining its shape. It is accomplished by either enlarging or reducing the figure with respect to a fixed point called the center of dilation. The scale factor determines the ratio by which the figure is resized. In the given diagram depicting the dilation of segment AB, let's analyze the statements to understand the properties of the dilation.

The dilation is an enlargement: An enlargement occurs when the scale factor is greater than 1, meaning the figure is proportionally expanded. In the diagram, if the scale factor is greater than 1, then the dilation is indeed an enlargement.

The dilation is a reduction: A reduction happens when the scale factor is between 0 and 1, implying that the figure is proportionally reduced. If the scale factor in the diagram falls within this range, then the dilation is also a reduction.

Point O is the center of dilation: The center of dilation is the fixed point about which the figure is resized. In the diagram, if point O is identified as the fixed point with respect to which segment AB is dilated, then this statement is true.

The scale factor is 3: If the scale factor mentioned in the diagram is 3, it indicates that the figure is enlarged by a factor of 3, making this statement true.

The scale factor is 9: If the scale factor is 9, then the figure is enlarged by a factor of 9, and this statement is also true.

The correct answer is: B. The function has no local maximums and has local minimums at approximately x = 5.8 and x = 28.8 (rounded to the nearest tenth).

To determine the location of the local extrema (maxima and minima) of the function f(x) = -0.697x^3 + 16642x^2 - 102407x + 650015, we need to find the critical points where the derivative of the function is equal to zero or does not exist. First, let's find the derivative of f(x) with respect to x: f'(x) = -2.091x^2 + 33284x - 102407. To find the critical points, we set f'(x) = 0 and solve for x: -2.091x^2 + 33284x - 102407 = 0. Using the quadratic formula, we can solve for x: x = (-b ± √(b^2 - 4ac)) / (2a). Plugging in the values a = -2.091, b = 33284, and c = -102407, we can calculate the values of x: x ≈ 5.779 or x ≈ 28.755. These are the potential locations of the local extrema.

To determine whether these points are maxima or minima, we can analyze the concavity of the function. Taking the second derivative, we have: f''(x) = -4.182x + 33284. Setting f''(x) = 0 and solving for x: -4.182x + 33284 = 0; x ≈ 7963.28. Since the second derivative is negative for x < 7963.28, we can conclude that x ≈ 5.779 corresponds to a local maximum, and x ≈ 28.755 corresponds to a local minimum. Therefore, the correct answer is: B. The function has no local maximums and has local minimums at approximately x = 5.8 and x = 28.8 (rounded to the nearest tenth).

The situation of popcorn scooping at Pineville County Fair can be modeled as a linear relationship.

A linear relationship is a type of relationship between two variables that can be represented by a straight line. In this case, the two variables are the amount of popcorn in the container and the number of bags filled. As Vivian scoops popcorn from the container, the amount of popcorn decreases, and the number of bags filled increases. This creates a linear relationship between the two variables.

To model this relationship, we can use the equation of a straight line, which is y = mx + b, where y represents the dependent variable (in this case, the number of bags filled), x represents the independent variable (the amount of popcorn in the container), m represents the slope of the line, and b represents the y-intercept.

In this situation, the slope represents the rate at which Vivian is filling bags with popcorn, and the y-intercept represents the initial number of bags filled when the container is full. By analyzing the data, we can estimate the slope and y-intercept and use the linear model to make predictions about the amount of popcorn remaining in the container and the number of bags that can still be filled.

Overall, the linear relationship provides a useful tool for understanding and managing the popcorn scooping process at the Pineville County Fair.
