Answer:

Therefore, the total used car sales were $179,625.

Step-by-step explanation:

Let's assume that the ratio of new car sales to used car sales is 3x:5x, where x is a constant.

The total car sales were $287,400, which means the sum of the new car sales and used car sales is $287,400:

3x + 5x = 8x

So, the total sales can be expressed as:

8x = $287,400

To find the value of x, we need to divide both sides by 8:

x = $35,925

Now, we can calculate the used car sales by multiplying 5x by the value of x:

Used car sales = 5x * x = 5 * $35,925 = $179,625

Therefore, the total used car sales were $179,625.

Answer:

Since only 66 states approve the amendment, it falls short of the required 7/9 majority. Therefore, the constitution will not be amended.

Step-by-step explanation:

To determine whether the constitution will be amended, we need to compare the number of states that have approved the amendment to the required number of states needed for approval.

The requirement is that 7/9 of the 84 states must approve the amendment. So, we need to calculate 7/9 of 84 to find out how many states need to approve the amendment:

(7/9) x 84 = 66.67

Rounding up, we see that 66.67 is equivalent to 67 states. This means that in order for the amendment to be approved, at least 67 states must approve it.

Since only 66 states approve the amendment, it falls short of the required 7/9 majority. Therefore, the constitution will not be amended.

The length of the side of the tent is 5.8 feet calculated using the height of the equilateral triangle.

An equilateral triangle is a type of triangle where all three sides have the same length, and all three angles are equal to 60 degrees.

The formula for the height of an equilateral triangle is given by

Where 'a' is the equal side of the equilateral  

In the given problem we use the height of the triangle to calculate the side of the triangle tenth.

Here we have  

The height of the tent is 5 ft which is the height of the equilateral triangle  

As we know,

Height of equilateral triangle =  ½(√3a)

Let 'a' be the side of the triangle tent

=> 5 ft = ½(√3a)

Multiply by 2 on both sides

Elijah's total earnings for the week if he made x dollars in sales would be: $500 + 0.3x.

What is sale?

A sale is an event or activity in which goods or services are sold at a reduced or discounted price.

What is discount?

A discount is a reduction in the price of an item or service. It is often offered as a promotion or incentive to encourage customers to buy or use a product or service.

Total sales commission earned by Elijah for selling $775 worth of clothing:

30% of $775 = 0.3 x $775 = $232.50

Therefore, Elijah's total earnings for the week would be:

$500 (guaranteed salary) + $232.50 (commission) = $732.50

For selling x dollars worth of clothing, the commission earned by Elijah would be:

0.3x

Therefore, Elijah's total earnings for the week if he made x dollars in sales would be:

Answer:

Height = 630 / (14 x 0.9) = 47.5 cm

Answer: $194.79

Step-by-step explanation:

It is easiest to approach this question in two parts.

First part is simple - multiply the wage per hour times the number of whole number you have worked. ($12.50)(15) = $187.50

Next you need to find how much you make in 35 minutes at a wage rate of 12.50 an hour. You can set up a ratio to find this out -

($12.50) | (60 min)  -    (x dollars) | (35 min)

then cross multiply and divide -  (12.5 * 35) / 60 = 7.291

This means you make $7.29 for 35 minutes of work.

$187.50 + $7.29 = $194.79 for 15 hours 35 minutes of work.

(this is based on a per minute/hour scale)

The correct answer is (c) Left 5. The transformation is a horizontal shift to the left by 5 units.

An equation is a statement that shows the equality between two expressions. It typically contains one or more variables and may involve mathematical operations such as addition, subtraction, multiplication, division, exponentiation, or roots. An equation can be solved by finding the value(s) of the variable(s) that make the equation true. Equations are used extensively in mathematics, science, engineering, and other fields to describe relationships between different quantities and to make predictions or solve problems.

Here,

The given equation is y = 12/(x + 5), which represents a rational function. The parent function for this type of function is y = 1/x, which has a vertical asymptote at x = 0 and a horizontal asymptote at y = 0.

To transform the parent function represented by y = 1/x into y = 12/(x + 5), we need to apply the following transformations:

Vertical stretch by 12: This means that the y-values of the graph will be multiplied by a factor of 12, causing the graph to become narrower and taller. Horizontal shift left 5 units: This means that the graph will be shifted 5 units to the left, causing the vertical asymptote to move from x = 0 to x = -5.

Therefore, the correct answer is (c) Left 5, since this represents the horizontal shift of 5 units to the left. The other answer choices do not accurately describe the transformation of the parent function into the given equation.

Answer:

Step-by-step explanation:

To determine the value of the offer today, we need to calculate the present value of all the cash flows using a discount rate of 8.25%.

First, let's calculate the present value of the salary payments.

PV(year 1 salary) = R55 000 / (1 + 0.0825)^1 = R50 760.87

PV(year 2 salary) = R60 000 / (1 + 0.0825)^2 = R51 423.95

PV(year 3 salary) = R65 000 / (1 + 0.0825)^3 = R52 110.69

Next, let's calculate the present value of the starting bonus.

PV(starting bonus) = R4 500 / (1 + 0.0825)^0 = R4 500

Finally, we can add up all the present values to find the total present value of the offer:

PV(total offer) = PV(year 1 salary) + PV(year 2 salary) + PV(year 3 salary) + PV(starting bonus)

PV(total offer) = R50 760.87 + R51 423.95 + R52 110.69 + R4 500

PV(total offer) = R158 795.51

Therefore, the offer is worth R158 795.51 to you today at a discount rate of 8.25%.

The population in the year 2100 will be approximately 18.8 billion.

Determine exponential equation

The exponential equation to model the world population (in billions) after t years is P(t) = 8(1.011)[tex]^t[/tex], where P(t) is the population in billions and t is the number of years after 2022.

To write this equation, we need to use the information provided in the question. The initial population in 2022 is 8 billion, so this is our starting value. The growth rate is 1.1% per year, which can be written as 1.011 in decimal form.

We can use the formula for exponential growth, P(t) = P0(1 + r[tex])^t[/tex]where P0 is the initial population, r is the growth rate, and t is the number of years.

Substituting the values for [tex]P_0[/tex]and r into the equation, we get:

P(t) = 8(1.011[tex])^t[/tex]

2100-2022=78

This equation can be used to find the population after t years.

For example, to find the population after 5 years, we can substitute t = 78 into the equation and get:

P(5) = 8(1.011[tex])^78[/tex] ≈ 18.8 billion

Therefore, the population in year  2100 will be approximately 18.8 billion.

Graphically speaking, quadratic functions have the form of the parabola. The zeros are the points of parabola that are on the horizontal axis (x-axis) and the vertex is the only point of the parabola. The factor form of the parabola is:

y = C · (x - r₁) · (x - r₂)

Where:

Now we proceed to determine all the features of the quadratic function:

Case 1

Roots: r₁ = - 2, r₂ = 2

Vertex: (h, k) = (0, - 16)

C = y / [(x - r₁) · (x - r₂)]

C = - 16 / [2 · (- 2)]

C = - 16 / (- 4)

C = 4

Factor form: y = 4 · (x + 2) · (x - 2)

Case 2

Roots: r₁ = - 5, r₂ = 3

Vertex: (h, k) = (- 1, - 8)

C = y / [(x - r₁) · (x - r₂)]

C = - 8 / [(- 1 + 5) · (- 1 - 3)]

C = - 8 / [4 · (- 4)]

C = - 8 / (- 16)

C = 1 / 2

Factor form: y = (1 / 2) · (x + 5) · (x - 3)

Case 3

Roots: r₁ = - 4, r₂ = - 2

Vertex: (h, k) = (- 3, 2)

C = y / [(x - r₁) · (x - r₂)]

C = 2 / [(- 3 + 4) · (- 3 + 2)]

C = - 2

Factor form: y = - 2 · (x + 4) · (x + 2)

Case 4

Roots: r₁ = - 6, r₂ = - 2

Vertex: (h, k) = (- 4, 8)

C = y / [(x - r₁) · (x - r₂)]

C = 8 / [(- 4 + 6) · (- 4 + 2)]
