To answer your question the list price for Emily's vehicle would have a $23,655.91 list price

Hope this helped

Aaron

Answer:  The list price of the car was $ 23655.91.

Step-by-step explanation:  Given that Emily bought a new car for $22000 and she paid 93% of the list price.

We are to find the list price of the car.

Let $ x denote the list price of the car.

Then, according to the given information, we have

[tex]93\%\times x=22000\\\\\\\Rightarrow \dfrac{93}{100}\times x=22000\\\\\Rightarrow 93x=22000\times100\\\\\Rightarrow 93x=2200000\\\\\Rightarrow x=\dfrac{2200000}{93}\\\\\Rightarrow x=23655.91.[/tex]

Thus, the list price of the car was $ 23655.91.

Answer:

answer is 5

Step-by-step explanation:

Answer:

1, 3, 5

Step-by-step explanation:

The sum of an arithmetic series is:

S_n = n (a_1 + a_n) / 2

100 = n (1 + 19) / 2

n = 10

The nth term of an arithmetic sequence is:

a_n = a_1 + d (n − 1)

19 = 1 + d (10 − 1)

d = 2

The common difference is 2.  So the first three terms are 1, 3, and 5.

The volume of the prism is [tex]\(V = 648 \, \text{cubic units}\).[/tex]

The formula for the volume (V) of a rectangular prism is given by [tex]\(V = lwh\),[/tex] where (l) is the length, (w) is the width, and (h) is the height. In this case, the provided dimensions are length (l = 18), width (w = 9), and height (h = 4). Substituting these values into the formula: [tex]\[ V = 18 \times 9 \times 4 = 648 \, \text{cubic units}. \][/tex] Therefore, the volume of the prism is [tex]\(648 \, \text{cubic units}\).[/tex]

Understanding the concept of volume in three-dimensional geometry is vital. The formula [tex]\(V = lwh\)[/tex] reflects the relationship between the length, width, and height of a rectangular prism. Multiplying these dimensions provides the total space enclosed by the prism in cubic units. In this instance, with a length of 18 units, a width of 9 units, and a height of 4 units, the volume calculation yields [tex]\(648 \, \text{cubic units}\),[/tex] representing the spatial capacity of the given prism.

Calculating the volume of prisms is a fundamental skill in geometry and has practical applications in various fields, including architecture and engineering. This calculation allows us to quantify the amount of space a three-dimensional object occupies, providing essential information for design and analysis. In this case, the resulting volume, [tex]\(648 \, \text{cubic units}\),[/tex] represents the capacity of the rectangular prism specified by the given dimensions.

For this case we have a fucnion of the form [tex]y = f (x)[/tex]

Answer:

The number of calories in a peanut treat is 30.

The number of calories in a coconut treat is 25.

Step-by-step explanation:

So we have Ben ate 2 peanut treats (let p represent the calories in each peanut treat) and 4 coconut treats (let c represent the calories in each coconut treat).  The sum of those calories is 160.

This is the equation for Ben:

2p+4c=160

I'm going to use the same representation here.  p for the number of calories in each peanut treat and c for the number of calories in each coconut treat.

Arnold ate 3 p's and 2 c's for a sum of 140 calories:

Alrnoldo's equation is:

3p+2c=140

So we have the system:

2p+4c=160

3p+2c=140

I'm going to divide the first equation by 2 because each term is divisible by 2:

p+2c=80

3p+2c=140

This system is setup for elimination because the equations are in the same form and the second column have the same variable expression, 2c.  So we are going to subtract to eliminate the variable c, that is 2c-2c=0.

p+2c=80

3p+2c=140

---------------------Subtract!

-2p+0=-60

-2p    =-60

Divide both sides by -2:

  p      =30

So if p=30 and p+2c=80 , then 30+2c=80.

So let's solve:

30+2c=80 for c

Subtract 30 on both sides:

     2c=50

Divide both sides by 2:

     c=25

The number of calories in a peanut treat is 30.

The number of calories in a coconut treat is 25.

Rewrite 1/2 to have a common denominator with 2/6

1/2 x 3 = 3/6

Now you have 1 and 3/6 - 2/6  = 1 and 1/6

Now rewrite 2/3 to have a common denominator with 1/6: 2/3 x 2 = 4/6

Subtract 1/6 from 4/6:

4/6 - 1/6 = 3/6 = 1/2

You will need to add 1/2

To get from the difference between 1 and 1/2 and 2/6 to 1 and 2/3, one must add 1/2 after ensuring both differences have a common denominator.

To find out what should be added to the difference between 1 and 1/2 and 2/6 to get 1 and 2/3, we need to perform a few steps involving fractions. First, let's convert 1 and 1/2 into an improper fraction by multiplying 1 (the whole number) by 2 (the denominator of the fractional part) and adding 1 (the numerator of the fractional part), which gives us 3/2. Now, to find the difference between 3/2 and 2/6, we must have a common denominator, which is 6 in this case. Multiplying the numerator and denominator of 3/2 by 3 gives us 9/6.

Now we subtract 2/6 from 9/6 to get the difference, which is 7/6 or 1 and 1/6. To find what needs to be added to this difference to get 1 and 2/3, we must also express 1 and 2/3 as an improper fraction. Multiplying 1 (the whole number) by 3 (the denominator) and adding 2 (the numerator) gives us 5/3.

To compare 7/6 with 5/3, we need the same denominator, which is 6. So we multiply the numerator and denominator of 5/3 by 2 to get 10/6. Subtracting 7/6 from 10/6, we find the missing number to be 3/6, which simplifies to 1/2.

Answer:

The equation is (x+9)^2 + (y-3)^2 = 5

Step-by-step explanation:

The standard form for the equation of a circle is:

(x−h)^2+(y−k)^2=r2

The center of the circle is the midpoint of the diameter.

So the midpoint of the diameter at  (-10, 1) and (-8, 5) can be determined as:

(-10 +(-8))/2 , (1+5)/2

= -10-8/2, 1+5/2

= -18/2 , 6/2

= -9 , 3

Thus(-9,3) is the center of the circle.

Now we will use the distance formula to find the radius of the circle.

r^2=(-10-(-9))^2 + (1-3)^2

r^2=(-10+9)^2 +(-2)^2

r^2=(-1)^2 + (-2)^2

r^2=1 + 4

r^2= 5

Take square root at both sides.

√r^2= √5

r=√5

Now put the values in the 1st equation.

(x−h)^2+(y−k)^2=r2

where h = -9, k =3 and r = √5

(x-(-9))^2 + (y-3)^2= (√5)^2

(x+9)^2 + (y-3)^2 = 5

Thus the equation is (x+9)^2 + (y-3)^2 = 5 ....

The question is about translating the graph of the function y = 3/x. The graph of y = 3/(x - 1) + 3 results from shifting the parent function to the right by 1 unit and upwards by 3 units on the coordinate grid.

The question pertains to the translation of a rational function on the coordinate grid and is related to graph transformations. The function y = 3/x is known as the parent function, and y = 3/(x - 1) + 3 is the transformed function. To illustrate the translation, we can understand the changes in terms. Here x - 1 indicates a horizontal shift to the right by 1 unit, and +3 signifies a vertical shift upwards by 3 units. The new graph represents these translations on the coordinate system, which is a two-dimensional representation with x and y-axes as described in the reference information provided.

Answer:

1/3

Step-by-step explanation:

The formula for computing the sum of an infinite geometric series is

[tex]S=\frac{a_1}{1-r}[/tex] where r is between -1 and 1 and [tex]r[/tex] is the common ratio, and [tex]a_1[/tex] is the first term of the series.

So let's plug in:

[tex]S=\frac{0.3}{1-0.1}[/tex]

[tex]S=\frac{0.3}{0.9}[/tex]

[tex]S=\frac{3}{9}[/tex] I multiplied bottom and top by 10.

[tex]S=\frac{1}{3}[/tex] I divided top and bottom by 3.

The sum is 1/3.

The sum of the infinite geometric series is 1 / 3.

When there is a constant between the two successive numbers in the series then it is called a geometric series. In other words, every next term is multiplied with that constant term to form a geometric progression.

Given that the first term a₁ = 0.3 and common ratio r = 0.1. The sum of the geometric series is calculated by using the formula below:-

S = a₁ / ( 1 - r )

S = 0.3 / ( 1 - 0.1 )

S = 0.3 / 0.9

S = 3 / 9

S = 1 / 3

Therefore, the sum of the infinite geometric series is 1 / 3.

The dimensions of one of the identical triangles pieces of the plane are 2 cm base and 3 cm height

Answer:

The correct option is 1. The dimensions of one of the identical triangular pieces of the plane are 2 cm base and 3 cm height.

Step-by-step explanation:

From the given figure it is noticed that the length of parallel sides of the trapezoid are 6 cm and 2 cm.

The height of triangular pieces is same as the height of trapezoid. So the height of triangular pieces is 3 cm.

Let the measure of base of the triangular pieces be x.

[tex]x+2+x=6[/tex]

Combine like terms.

[tex]2x+2=6[/tex]

Subtract 2 form both the sides.

[tex]x=7 \frac{3}{7}[/tex] gallons

Step-by-step explanation:

So we are given:

70 miles   ->  1 gallon is used.

520 miles ->  x gallons is used.

Set up a proportional to solve.

I lined up everything already above:

[tex]\frac{70}{520}=\frac{1}{x}[/tex]

Cross multiply:

[tex]70(x)=520(1)[/tex]

[tex]70x=520[/tex]

Answer: [tex]\bold{focus: \bigg(2, -7 \dfrac{1}{8}\bigg), \quad directrix: y = -6 \dfrac{7}{8}}[/tex]

Step-by-step explanation:

First, rearrange the equation into vertex form: y = a(x - h)² + k   where

NOTE: p is the distance from the vertex to the focus

      y = -2x² + 8x - 15

y + 15 = -2x² + 8x            → added 15 to both sides

y + 15 = -2(x² - 4x)           → factored out -2 from the right side

y + 15 + (-2)(4) = -2(x² - 4x + 4)    → completed the square

y + 7 = -2(x - 2)²                → simplified

     y = -2(x - 2)² - 7           → subtracted 7 from both sides

Now it is in vertex form where:

Focus = (2, -7 + p)  →  Focus = (2, -7 + (-1/8))   →  [tex]Focus = \bigg(2, -7 \dfrac{1}{8}\bigg)[/tex]

Directrix: y = -7 - p   →  Directrix: y = -7 - (-1/8)   →  [tex]Directrix: y = -6 \dfrac{7}{8}[/tex]
