While on vacation in Dallas, Texas, the cab ride for the DFW airport to the hotel is 15 miles. The total cost of the cab ride was $25.50. The cab driver charges $1.50 permile for the entire trip. Write an equation that can be used to determine how much a cab ride would cost anywhere in Dallas.

Answers

Answer:

c=1.50x+3, where:

c=total cost of a cab ride anywhere in Dallas.

x=number of miles

Step-by-step explanation:

From the information given, you can multiply the price per mile for the number of miles:

1.5*15=22.5

You know that the total cost of the cab ride for the DFW airport to the hotel was 25.50:

25.50-22.50=3

This indicates that there is an additional charge for $3.

From this, you can say that the total cost of a cab ride anywhere in Dallas would be equal to the price per mile for the number of miles plus 3. According to this, the equation to calculate the total cost of a cab ride would be:

c=1.50x+3, where:

c=total cost of a cab ride anywhere in Dallas.

x=number of miles

The revenue for a company producing widgets is given by y = -10x2 - 25x + 125, where x is the price in dollars for each widget. The cost of the production is given by y = 60x - 10. Determine the price that will allow the production of the widget to break even.

Answers

When they create 3.44 products and make a revenue of $76.027, they will break even.

Step-by-step explanation:

To do this, simply graph the 2 equation in a graphing calculator and analyze the graph for where the 2 graphs intersect. Discard the negative intersection because we cannot have a negative production. You should see that your intersection point is (3.441, 76.027).

Which is a correct first step in solving the inequality -4(2x - 1) > 5 - 3x?

Answers

Step-by-step explanation:

opening the bracket,the equation therefore is

-8x + 1 > 5 - 3x

add 8x to both sides

- 8x + 8x +1 > 5 - 3x + 8x

1 > 5 + 5x

subtract 5 from both sides

1 - 5 > 5 - 5 + 5x

-4 > 5x

Divide through by 5

-4/5 > x

which is therefore written is

x < -4/5

7. Use the base angles of triangle ABC to find the measure of angle CBD.

Answers

Answer:

96

Step-by-step explanation:

For those of you who have an 84 angle for angle D and E isosceles trapezoid the base legs will be equal due to the congruent legs, all of the interior angles of a trapezoid will add up to 360, D and E equal 84, 360-84-84 would be 192, now since the base angles are equal due to the congruent legs 192/2 would be 96. Angles B and C are 96.

The external angles of a triangle are those created outside of it. The measure of ∠CBD is 132°.

What is an exterior angle?

The external angles of a triangle are those created outside of it. In other terms, a triangle's external angle is the angle produced between one of its sides and its neighbouring extended side.

The diagram for the given condition can be made as shown below.

In a triangle, the sum of two interior angles is equal to the exterior angle for the angle which is left. Therefore, the measure of ∠CBD can be written as,

∠CBD = ∠BAC + ∠BCA

∠CBD = 43° + 89°

∠CBD = 132°

Hence, the measure of ∠CBD is 132°.

The complete question is:

Triangle ABC with the measure of ∠A equal to 43° and the measure of ∠C equal to 89°. Ray AD passes through point B, creating external angle CBD.

Based on the information provided, what is the measure of ∠CBD?

[tex]17.51[/tex] = [tex]\frac{1751}{100}[/tex]

[tex]3.4[/tex] = [tex]\frac{17}{5}[/tex] = [tex]3\ \frac{2}{5}[/tex]
