The bus is approximately 373.8 feet away from the base of the l'Arc de Triomphe

To solve this problem, we can use trigonometry. Let's assume that the bus is at point A on the street, and the top of the l'Arc de Triomphe is at point B. The height of the arc is 162 feet.

We want to find the distance AB, which is the horizontal distance from the bus to the base of the arc. We know that the angle of elevation from the bus to the top of the arc is 34 degrees. Let's call the height of the bus H, and the distance AB D.

From the perspective of the bus, we can see that the height of the arc and the height of the bus together form a right triangle with angle of elevation 34 degrees. Therefore, we have:

tan(34) = (162 + H)/D

We can solve this equation for D:

D = (162 + H)/tan(34)

We need to find H to solve for D. To do this, we can use similar triangles. The triangle formed by the bus, the base of the arc, and the top of the arc is similar to the triangle formed by the bus, the ground, and the point directly beneath the top of the arc. Let's call the distance from the base of the arc to the point directly beneath the top of the arc x.

From the perspective of the bus, we can see that the height of the arc and the distance from the base of the arc to the point directly beneath the top of the arc together form a right triangle with angle of elevation 34 degrees. Therefore, we have:

tan(34) = 162/x

Solving for x, we get:

x = 162/tan(34)

Now, the height of the bus is simply H = x*tan(34). Substituting this into the equation for D, we get:

D = (162 + x*tan(34))/tan(34)

Substituting the value of x, we get:

D = (162 + (162/tan(34))*tan(34))/tan(34) = 373.8 feet (rounded to the nearest tenth)

Therefore, the bus is approximately 373.8 feet away from the base of the l'Arc de Triomphe.

The longest side of a triangle with angles of 50°, 60°, and 70° and a length of 9 furlongs on the shortest side is approximately 12.2 furlongs.

             The Law of Cosines is used to find the remaining parts of an oblique (non-right) triangle when either the lengths of two sides and the measure of the included angle are known (SAS) or the lengths of the three sides (SSS) are known.

         To calculate this, using the Law of Cosines formula,

  which is:

                [tex]c^2 = a^2 + b^2 - 2abcosC[/tex]

where c is the longest side, a is the shortest side, b is the other side of the triangle, and C is the angle

between a and b.

In this case, c = 12.2 furlongs,

                    a = 9 furlongs,

                    b is the side opposite the angle 70°, and C = 70°.

So the formula becomes:

        [tex]c^2 = 92 + b^2 - 2(9)(b)cos70^{o}[/tex]

Solving for b gives us b = 12.2 furlongs, which is the length of the longest side.

The solution to the system of equations is x = 5 and y = -3.

We can use the elimination method by multiplying the second equation by 2 and adding it to the first equation to eliminate y:

= -4y + 11x - 67 + 2(2y + 5x - 19) = 0

-4y + 11x - 67 + 4y + 10x - 38 = 0

21x - 105 = 0

Dividing both sides by 21, we get:

x - 5 = 0

So x = 5.

Now we can substitute x = 5 into either of the original equations:

2y + 5x - 19 = 0

2y + 5(5) - 19 = 0

y = -3

Thus, the solution to the system of equations is:

x = 5, and y = -3.

If the objective function coefficient for variable 1 decreases by 20, the solution will shift in the direction of the decrease in the objective function coefficient. It means that the optimal solution that was obtained previously will no longer remain optimal, and the new optimal solution will be found with the new objective function coefficient.

In linear programming, the objective function determines the maximum or minimum value that can be attained in the solution, subject to the constraints. The constraints in the problem can be either equalities or inequalities, which limit the range of values that the decision variables can take on.

The change in the objective function coefficient will change the direction of the optimal solution, and it may affect the feasibility of the solution. It means that some constraints may no longer be satisfied, or some variables may become infeasible.

In such cases, it will be necessary to revise the constraints or the variables to ensure the feasibility of the solution.

The solution can also be affected if the constraints of the problem change. The new constraints may limit the range of values that the variables can take on, or they may add new variables to the problem. These changes can affect the feasibility of the solution, and it may require the problem to be solved again to obtain the new optimal solution.

The statements when converted to unit rates are $1.20 per lap and $37.50 per hour

To compare the pricing options, we can convert each to a unit rate, which is a rate with a denominator of 1.

This allows us to compare the cost of each option per lap or per hour.

i. $30 for 25 laps:

To find the unit rate, we can divide the total cost by the number of laps:

Unit rate = $30 ÷ 25 laps = $1.20 per lap.

ii. $75 for 2 hours:

To find the unit rate, we can divide the total cost by the number of hours:

Unit rate = $75 ÷ 2 hours = $37.50 per hour.

So, the unit rate for option i is $1.20 per lap and the unit rate for option ii is $37.50 per hour.

By comparing the unit rates, we can determine which pricing option is more cost-effective based on the number of laps or hours Alex wants to ride.

The surface area of the triangular prism Milo paints red is equal to 186 square centimeters.

The triangular prism have two triangle and three rectangle faces, so we shall calculate for each area of the faces and add them to get the surface area of the triangular prism as follows:

area of triangle = 1/2(base × height)

area of one triangle face = 1/2(6 cm × 4 cm)

area of one triangle face = 12 cm²

area of two triangle faces = 2 × 12 cm² =24 cm²

area of one rectangle face = 10.8 cm × 5 cm

area of one rectangle face = 54 cm²

area of three rectangle faces = 162 cm²

area of the triangular prism = 24 cm² + 162 cm³

area of the triangular prism = 186 cm²

Therefore, the surface area of the triangular prism Milo paints red is equal to 186 square centimeters.

Answer:

Since the decoration is in the shape of a triangle, we can use the formula for the area of a triangle to solve for its height. The area of a triangle is given by:

Area = (1/2) x base x height

Let's call the height of the decoration h. We know that the base after firing is 9 inches, so we can plug in the given values and solve for h:

Area = (1/2) x 9 x h

Area = 4.5h

We don't know the exact area of the decoration, but we do know that the decoration maintains its shape after firing. This means that the ratio of the areas before and after firing is the same, and so is the ratio of the heights and bases. Since the height and base are proportional, we can write:

h / 15 = 9 / 10

Simplifying the equation, we get:

h = (9/10) x 15

h = 13.5

Therefore, the height of the finished decoration is 13.5 inches.

The decision that most clearly reflects a lack of understanding of the concept of sunk costs is "You study eight hours for a final exam even though there is no way now that you can pass the course".

Sunk costs refer to any costs that have already been incurred and cannot be recovered. Sunk costs are irrelevant in decision-making because they are already gone and cannot be recovered. Decision-makers must only consider future costs and benefits when making decisions.

A lack of understanding of sunk costs may result in individuals making decisions based on past costs rather than future costs and benefits. Decision-making that is influenced by sunk costs may result in inefficient resource allocation and lost opportunities.

Individuals must ignore sunk costs and instead focus on future costs and benefits to make effective decisions.

In the given options, "You study eight hours for a final exam even though there is no way now that you can pass the course" is the decision that most clearly reflects a lack of understanding of the concept of sunk costs.
