Answer:

2.94

Step-by-step explanation:

3.29 - 35/100 = 2.94

Answer: 100 rides are needed to break even.

Step-by-step explanation:

C(x)=15x+2000 - x is the number of rides.

R(x)=35 x , where x is the number of rides

35x=15x+2000

35-15x=2000~subtract 15x from both sides~

20x=2000 ~simplify~

x=2000/20 ~dividing both sides by 20~

x=100

Answer:

Short-term investments, also known as marketable securities or temporary investments, are those which can easily be converted to cash, typically within 5 years. Many short-term investments are sold or converted to cash after a period of only 3-12 months. Some common examples of short term investments include CDs, money market accounts, high-yield savings accounts, government bonds and Treasury bills. Usually, these investments are high-quality and highly liquid assets or investment vehicles.

Step-by-step explanation:

lenght :

[tex]2x - 3[/tex]

breadth :

[tex]4x + 5[/tex]

AREA = LENGTH × BREADTH

[tex] = (2x - 3) \times (4x + 5)[/tex]

multiplying the above gives :

[tex] = 8 {x}^{2} + 10x - 12x - 15[/tex]

[tex] = 8 {x}^{2} - 2x - 15[/tex]

Answer:

Answer A

Step-by-step explanation:

In the equation [tex]\dfrac{10}{x^2-1}=\dfrac{15}{3x-3}[/tex], 1 makes the denominator zero and 1 is the solution of the equation derived from cross multiplication.

Given :

Option A)

Given :

[tex]\dfrac{10}{x^2-1}=\dfrac{15}{3x-3}[/tex]

The above expression is not defined for x equal to 1 so, 1 is an extraneous solution.

Simplify the above equation by doing the cross multiplication.

[tex]10(3x-3)=15(x^2-1)[/tex]

[tex]30(x-1)=15(x-1)(x+1)[/tex]

2 = x + 1

x = 1

In the given equation 1 makes the denominator zero and 1 is the solution of the equation derived from cross multiplication.

Therefore, the correct option is A) and therefore, no need to check the other options.

Answer:

3, 4, and 5

Step-by-step explanation:

Given: We're looking for x, x+1, and x+2

Requirements: (x+1)+(x+2)=3(x)

Solve equation:

x+1+x+2=3x

2x+3=3x

3=x

This means the three consecutive integers are 3, 3+1, and 3+2 which is the same as 3, 4, and 5

Answer: 1/2x + 1/3

Step-by-step explanation:

Given:

1/4(x) + 3/4(x) - 1/2(x) + 1 - 2/3

Step 1: Combine like terms

1/4(x) and 3/4(x) have a common denominator of 4.  This means that you can add them together.

1/4(x) + 3/4(x) = 4/4(x) = x

Step 2: Find the common denominator of x in step 1 and combine like terms  

x - 1/2(x) = 2/2(x) - 1/2(x)

Now that we have the common denominator of x, we can combine like terms.  Its the same as adding or subtracting fractions without a variable.  In this case, you must subtract 1/2(x) from 2/2(x).

2/2(x) - 1/2(x) = 1/2(x)

Step 3: Find the common denominator of the constants and combine like terms

1 - 2/3 = 3/3 - 2/3

Now combine like terms.  Simply subtract 2/3 from 3/3.

3/3 - 2/3 = 1/3

Step 4: Write the simplified equation

1/2(x) + 1/3

This is the answer

Answer: Mixture C. 1:3

Step-by-step explanation:

given data:

Answer and Step-by-step explanation:

Question #10.

We are told to fill in the blank that corresponds to a property of congruence for like KM and line KM.

A property that states that something is equal to itself if the Reflexive Property of Congruence.

The Reflexive Property of Congruence is the answer. This is because it comes from a latin word called reflexus (also known as reflect), which is when something is the same of itself. In this case, the line KM is reflexive, or congruent to itself because when reflected, it reflects onto itself.

A parallelogram is a quadrilateral , In which opposite sided are equal and parallel to each other.

The coordinate of point C are (a + b , c)

The coordinates of the midpoint of diagonal BD are [tex](\frac{a+b}{2},\frac{c}{2} )[/tex]

AC and BD intersect at point E with coordinates [tex](\frac{a+b}{2},\frac{c}{2} )[/tex]

By the definition of midpoint, AE ≅ CE  and BE ≅ DE.

Therefore, diagonals AC and BD bisect each other.

Properties of Parallelogram shown below,

Since, Diagonals of a parallelogram bisect each other. Therefore, point E is the mid point of both diagonal AC and BD.

Let us consider , coordinate of point C are (x, y)

By using mid point formula,

                Coordinate of point E =  [tex](\frac{x}{2},\frac{y}{2} )[/tex]

                        [tex](\frac{a+b}{2},\frac{c}{2} )=(\frac{x}{2},\frac{y}{2} )[/tex]

  So,     [tex]C(x,y)=(a+b,c)[/tex]

E is the point at which both diagonal bisect to each other. Therefore, E is the mid point of both diagonal AC and BD.

So, coordinate of point E are [tex](\frac{a+b}{2},\frac{c}{2} )[/tex]

Thus, By the definition of midpoint, AE ≅ CE  and BE ≅ DE.

Therefore, diagonals AC and BD bisect each other.
