Answer:

1647.2

Step-by-step explanation:

5.8% times 28,400 = 1647.2

5.8% = 5.8/100 = .058

so .058 times 28,400 = 1647.2

Final answer:

To find the commission, convert the rate to decimal by dividing by 100 then multiply by the sale price. A salesperson earns 5.8% commission, resulting in $1,647.20 for a $28,400 car.

Explanation:

To calculate the commission a car salesperson earns on the sale of a car, you first need to understand that commission is a percentage of the sale price they receive as their payment. In this case, the salesperson earns a 5.8% commission on each car sold. To find out how much commission they would earn on a $28,400 car, the following calculation is performed:

Sale price of car = $28,400
Commission rate = 5.8%

First, convert the commission rate from a percentage to a decimal by dividing by 100:
5.8% / 100 = 0.058

Next, multiply the sale price by the decimal commission rate:
$28,400 x 0.058 = $1,647.20

Therefore, the commission earned on the $28,400 car is $1,647.20.

Answer:

C

Step-by-step explanation:

to factor x² - x - 2

consider the factors of the constant term which sum to give the coefficient of the x-term.

the factors are - 2 and + 1 since - 2 × 1 = - 2 and - 2 + 1 = - 1

x² - x - 2 = (x - 2)(x + 1), hence (x + 1) is a factor

The relationship between (x + 1) and the polynomial x² - x - 2 is that            ( x + 1) is a factor of x² - x - 2.

A mathematical expression of one or more algebraic terms each of which consists of a constant multiplied by one or more variables raised to a non negative integral power.

The given polynomial is x² - x - 2.

x² - x - 2

= x² - 2x + x - 2

= x( x - 2) + 1( x - 2)

=( x - 2) ( x + 1)

So we can see that, ( x + 1) is a factor of x² - x - 2.

So, option C is correct.

  [tex]\dfrac{10\sqrt{3}}{3}[/tex]

Step-by-step explanation:

You want the length of the hypotenuse in a 30°-60°-90° right triangle with long leg 5.

The ratios of side lengths in a 30°-60°-90° triangle is ...

  1 : √3 : 2

Multiplying these values by 5/√3 gives ...

  5/√3 : 5 : 10/√3

That is, the length of the side marked X is 10/√3.

The denominator can be rationalized by multiplying the fraction by 1 in the form of (√3)/(√3):

Answer:

y+9 =-5(x-2)  point slope form

y = -5x-1  slope intercept form

Step-by-step explanation:

If we have a slope and a point, we can use the point slope form of a line

y-y1 = m(x-x1)

y--9 = -5(x-2)

y+9 =-5(x-2)

If you want to write it in slope intercept form, distribute the -5

y+9 = -5x+10

Subtract 9 from each side

y+9-9 = -5x+10-9

y = -5x-1

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-40.86, 5.6) and (0.86, 4.2). Substitute:

[tex]m=\dfrac{4.2-5.6}{0.86-(-40.86)}=\dfrac{-1.4}{0.86+40.86}=-\dfrac{1.4}{41.72}=-\dfrac{140}{4172}\\\\=-\dfrac{140:4}{4172:4}=-\dfrac{35}{1043}=-\dfrac{35:7}{1043:7}=-\dfrac{5}{149}[/tex]

To rearrange the equation for a, subtract b/8c from both sides: a = 4x - b/8c.

To rearrange the equation for a, we start with the given equation 4x = a + b/8c. First, we isolate a by subtracting b/8c from both sides, giving 4x - b/8c = a. Therefore, the equation for a in terms of b, c, and x is a = 4x - b/8c.

Answer:  The correct option is (D) [tex]\dfrac{3-2}{0-2}=\dfrac{3-1}{0-4}.[/tex]

Step-by-step explanation:  Given that ΔCDE and ΔCFG are similar right triangles.

We are to select the correct proportion that can be used to show that the slope of CE is equal to the slope of CG.

We know that the slope of a line passing through two points (a, b) and (c, d) is given by

[tex]m=\dfrac{d-b}{c-a}.[/tex]

From the given figure, we note that the co-ordinates of the points C, E and G are

C(0, 3), E(2, 2) and G(4, 1).

So, the slope of line CE is given by

[tex]m_1=\dfrac{2-3}{2-0},[/tex]

and the slope of line CG is given by

[tex]m_2=\dfrac{1-3}{4-0}.[/tex]

Since the lines CE and CG are same, they must be parallel and hence they have equal slopes.

Therefore,

[tex]m_1=m_2\\\\\\\Rightarrow\dfrac{2-3}{2-0}=\dfrac{1-3}{4-0}\\\\\\\Rightarrow \dfrac{3-2}{0-2}=\dfrac{3-1}{0-4}.[/tex]

Thus, (D) is the correct option.

Answers:

Angle 1 is 40 degrees

Angle 2 is 90 degrees

Angle 3 is 50 degrees

===========================================

Explanations:

Triangle ABC is a reflection of triangle ADC over the line AC. Doing this reflection forms the kite ABCD. Or you can think of it as gluing two congruent triangles together (ABC and ADC). We can prove the two triangles ABC and ADC congruent by the SSS congruence property. Then we use CPCTC (corresponding parts of congruent triangles are congruent) to prove that angle 1 is 40.

Let E be the intersection of the two diagonals. Through similar reasoning as earlier, we can prove that triangle AEB is congruent to triangle AED, so that leads to angle 2 being 90 degrees because this angle adds to its counterpart to get 180. Both unknown angles are x each meaning x+x = 180 leads to x = 90. One property of kites is that the diagonals are perpendicular.

Triangle AED is a right triangle as discussed above. Therefore, the angle 3 and the 40 degree angle are complementary. If angle 3 is y, then y+40 = 90 giving y = 90-40 = 50, which is why angle 3 is 50 degrees.

Using angle theorems, the value of the angles m1 and m3 are 40° and 50° respectively.

Taking the midpoint of DB as O ;

Angle OAD and Angle OAB are equal

OAD = 40° ; OAB = 40°

A right angle is formed at O ;

Hence,

(O + D + A) = 180°

90° + D + 40° = 180° (Sum of interior angles of a triangle)

D = 180 - 130

D = 50°

Hence, m∠3 = 50°.

Therefore, the value of the angles m1 and m3 are 40° and 50° respectively.

Answer:

Infinite number of solutions.

Step-by-step explanation:

We have the equations,

1. 3x+3y=10

2. -9x-9y= -30

Now, if we multiply equation 1 with -3, we will obtain equation 2.

i.e. -3×(3x+3y)= -3×10

i.e. -9x-9= -30

So, we see that both the equations are same.

The equation 3x+3y=10 will have solution for many values of x and y.

Hence, the system will have infinite number of solutions.

Answer:

[tex]-9x-9y = -30[/tex]  ------(B)

To Find : Solution of the given system of equations

Solution :

We will solve it by using substitution method

Finding the value of x from equation (B)

⇒[tex]-9x-9y = -30[/tex]

⇒[tex]-9x= -30+9y[/tex]

⇒[tex]x= \frac{-30+9y}{-9}[/tex]

⇒[tex]x= \frac{-10+3y}{-3}[/tex]

Putting this value of x in  equation (B)

⇒ [tex]3( \frac{-10+3y}{-3})+3y=10[/tex]

⇒[tex]10-3y+3y = 10[/tex]

⇒[tex]10= 10[/tex]

Since x and y both gets eliminated from the equation we got 10 = 10

Since the equations represent the same line.

If a consistent dependent system that has an infinite number of solutions

Hence there is infinite solution .

Final answer:

To find the list price of the poster after an 8% discount, subtract 8% of the list price from the list price and set it equal to the sale price.

Explanation:

To find the list price of the poster, we need to first calculate the original price before the discount. Let's assume the list price is 'x' dollars. After an 8% discount, the sale price of the poster is $17.48.

We can set up an equation to solve for the list price: x - 8% of x = $17.48. To calculate 8% of x, we multiply x by 0.08.

So the equation becomes: x - 0.08x = $17.48. Combining like terms, we get 0.92x = $17.48. Dividing both sides by 0.92, we find that x = $19.

Answer:

C = 6 + 7.5 x

Step-by-step explanation:

Given,

The amount is $24.75 for entrance and 2.5 kilograms of strawberries.

⇒ Entrance fee + 2.5 kilograms of strawberries = $24.75

Since, Entrance fee = $ 6,

And,  the price for each kilogram of strawberries is constant.

⇒  $ 6 + 2.5 × 1 kilograms of strawberries = $24.75

⇒ 2.5 × 1 kilograms of strawberries = 18.75

⇒ 1 kilograms of strawberries = $ 7.5.

Thus, the cost of x  strawberries = 7.5 x

Also, the total charge for x strawberries = Entrance fee + the cost of x  strawberries

= 6 + 7.5 x

⇒ C = 6 + 7.5 x

Which is the required function formula.

The probability for the spinner landing on the dotted region is 1/2.

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lies in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

The probability for the given case is evaluated as,

P(Spinner lands on dotted region) = Total space for dotted region/100

                                                         = (25 + 12.5 + 12.5)/100

                                                         = 50/100

                                                         = 1/2

Hence, the probability that the spinner will land on a dotted region is 1/2.

Answer:

(1) 0.08x + 16

(2) 0.08x + 16=0.12x + 14

Step-by-step explanation:

Checking account A has a monthly fee of $16 and a per-check fee of $0.08

Per check fee is a constant rate that is 0.08

Let x represents the number of checks Cecily writes per month

1 check fee = 0.08

x checks fee = 0.08x

monthly fee is $16 , we add that as well

So total monthly fee charges for account A  is

0.08x + 16

checking account B has monthly fee of $14 and a per-check fee of $0.12.

1 check fee = 0.12

x checks fee = 0.12x

monthly fee is $14 , we add that as well

So total monthly fee charges for account B  is

0.12x + 14

(2) To find number of checks write per month for the accounts to charge the same in fees

WE set both expression , account A = account B

0.08x + 16=0.12x + 14

Subtract 0.12x on both sides

-0.04x + 16 = 14

Now subtract 16 on both sides

-0.04x = -2

Divide by -0.04 on both sides

So x= 50
