By using percentage, it can be calculated that-

Sticker price of the car =  $14291.75

What is percentage?

Suppose there is a number and the number has to be expressed as a fraction of 100. The fraction is called percentage

For example 11% means [tex]\frac{11}{100}[/tex] . Here 11 is expressed as a fraction of 100

This is a word problem on percentage

Base price of the car = $15455.40

Cost of option = $585

Destination charge = $675

The dealer's cost is 85% of the base and 82% of the options

Sticker price of the car = [tex]\frac{85}{100}\times 15455 + \frac{82}{100} \times 585 + 675[/tex]

                                      = 13137.09 + 479.7 + 675

                                      = $14291.75

The three formulas for slope are: Slope formula, slope-intercept formula, and at the point-slope formula

 1. Slope formula  : (y2-y1) / (x2-x1)

 2. Slope intercept formula:  y = mx + b

 3. Point slope formula: y - y1 = m(x - x1)

The slope is defined as the steepness of a line, which is described by the ratio of the vertical change between two points (rise) over the horizontal change between the same two points (run). The first formula is the most commonly used and is used when we know two points in a line. The second formula is a for the  slope and y-intercept and  the third one is the slope of a line and  a point on the line.

The slope (m) of the line that passes through the points (-8, 2) and (-11, 3) is -1/3.  

What is the slop of the line?

A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

We have,

The line that passes through the points (-8, 2) and (-11, 3),

Slop (m) = ?

The slope formula is:

m =  (y₂-y₁) ÷ (x₂-x₁)

so here,

m = (3 - 2) ÷ (-11 - (-8))

m = 1 ÷ (-3)

m = -1/3

Hence, the slope (m) of the line that passes through the points (-8, 2) and (-11, 3) is -1/3.

The age of the fossils is determined by the Radioactive carbon dating technique in which the half-life of carbon and found radioactive elements is determined to calculate the age of a fossil

Answer:

No, A and B do not have the same solution.

To find the solution to A, we need to isolate the variable x on one side of the equation and solve for its value. We can do this by subtracting x from both sides of the equation and then adding 2 to both sides. This gives us:

4x + 2 - x = 6 - x + 2

3x = 8

x = 8/3

To find the solution to B, we need to isolate the variable x on one side of the equation and solve for its value. We can do this by subtracting 2 from both sides of the equation. This gives us:

5x + 2 - 2 = 6 - 2

5x = 4

x = 4/5

As we can see, the solutions to A and B are different, so A and B do not have the same solution. The solution to A is x = 8/3, and the solution to B is x = 4/5.

In the inverse variation function, when x and y are given, the value of k will be K = x * y.

Inverse variation states that when the value of one quantity increases, then the value of another quantity decreases in the same proportion. It includes a relationship between variables that are mentioned as y=k/x where x and y are variables and k is constant.

Distance and speed can be taken as a great example of inverse variation. When speed increases distance decreases.

When 'K' is constant, we can find it by multiplying the x-coordinate by the y-coordinate. So,  we can say that in an inverse variation function, when x and y are given, the value of 'k' will be K =x*y.

The results obtained by using proportions to calculate are:

A) Valerie takes (4.995 ≅) 5 hours to drive to work on average after 10 days.

B) Valerie takes (9.4911 ≅) 9.5 hours to drive a total of 224.2 miles to work.

C) Valerie takes (20.98 ≅) 21 days to drive a total of 247.8 miles to work.

Proportions are the two ratios that are related by equality between them. I.e., w : x = y : z

We can rewrite them as

w/x = y/z or wz = xy

By using this relation, we can solve any of the variables.

It is given that,

Valerie takes, on average, 30 mins, to drive the 11.8 miles to her job every day.

So, from this, we can find the time taken by her for driving 1-mile using proportions.

I.e.,

for 11.8 miles → 30 min

then 1 mile → X min

⇒ 11.8 : 1 = 30 : X

⇒ 11.8X = 30

∴ X = 30/11.8 = 2.54 mins

A) The time it takes for her to drive to work on average after 10 days:

for 10 days, she drives 11.8 × 10 = 118 miles

So, the time taken for 118 miles × 2.54 min = 299.72 min

We know that for 60 min it is 1 hour, then for 299.72 min, it is 4.995 hours that is on average Valerie takes 5 hours to drive for 10 days.

B) The time it takes for her to drive a total of 224.2 miles to work:

We know that for 1 mile she takes 2.54 min, then for 224.2 miles, she takes 224.2 × 2.54 = 569.468 min

That means 569.468 min/60 = 9.49 hours ≅ 9.5 hours

Thus, she takes 9.5 hours to drive 224.2 miles.

C) The number of days she takes to drive a total of 247.8 miles to work:

We know that for 1 mile she takes 2.54 min, then for 247.8 miles, she takes 247.8 × 2.54 = 629.412 min

If she takes 30 min to drive per day, then the number of days for 629.412 min is

= 629.412 min/30 = 20.98 days ≅ 21 days.

Thus, she takes 21 days for driving 247.8 miles.
