Answer:

Finance charge = $200

Step-by-step explanation:

Cost of the T.V. = $1160

Steve did the down payment = $200

Monthly payment done by Steve = $22.5

Duration for the periodic payments = 2.5 years

Number of periodic payments to be done = 12 × 2.5

                                                                      = 30

Amount paid in periodic payments = Number of periodic payments done × amount paid in each month

= 30 × $55.25

= $1657.5

Total payment done = Down payment + Amount paid in periodic payments

                                  = $200 + $1657.5

                                  = $1857.5

Therefore, finance charges = Total payments done - cost of T.V.

                                              = 1857.5 - 1657.5

                                              = $200

Answer:

no solution

Step-by-step explanation:

Given

6(x - 4) = 6x + 4 ← distribute left side

6x - 24 = 6x + 4 ( add 24 to both sides )

6x = 6x + 28 ( subtract 6x from both sides )

0 = 28 ← not possible

This indicates the equation has no solution

Answer:

A

Step-by-step explanation:

B is wrong because it's saying to multiply the cost by $7.35.

C is wrong because it's telling you to add the amount of grams to $7.35.

A is the correct answer because you have to mutiply the cost by the grams which is what a number by a variable means.

Answer:

2hours

Step-by-step explanation:

Given data

Company A

charges a fixed amount of $10 plus $8 per hour

let the number of hours be x

and the total be y

y= 10+8x----------------1

Company B

charges a fixed amount of $6 plus $10 per hour for a one-person kayak.

let the number of hours be x

and the total be y

y= 6+10x----------------2

Equate 1 and 2 above

10+8x= 6+10x

collcet like terms

10-6= 10x-8x

4= 2x

x= 2hours

Hence after 2 hours the charges will be the same

Answer:

ΔASA ≅ ΔASA

Step-by-step explanation:

Answer:

The given equation has one solution.

Step-by-step explanation:

Given equation is:

(x+12) = 4x-1

We will solve the equation to check how many solutions it has.

x+12 = 4x-1

Adding 1 on both sides

x+12+1 = 4x-1+1

x+13 = 4x

Subtracting x from both sides

x-x+13=4x-x

13 = 3x

x = 13/3

Hence,

The given equation has one solution.

Answer:

Commision may be defined as a percentage cut which an employee, broker, vendor, retailer or other persons within a sale chain receive from an employer or production firm for selling a good or offering a successful service based on agreed terms by both parties. ;

$18700

Step-by-step explanation:

Given :

Commision pattern :

5% on first $200,000

6% on remaining amount

Amount of commission on $345000

0.05 * 200000 = 10,000

0.06 * (345000 - 200000) = 8700

Total commission :

Answer:

  62°

Step-by-step explanation:

The measure of the external angle where the secants meet is half the difference of the arcs they subtend.

  ∠A = (DE - BC)/2

  2×∠A = DE -BC

  DE = BC + 2×∠A

  DE = 38° +2(12°)

  arc DE = 62°

Answer:

(a+9)(a-9)

Step-by-step explanation:

Both terms are perfect squares, use the difference of squares formula

a^2-b^2=(a+b)(a-b) where a=a and b=9

Answer:

they are perpendicular because they have slopes that are negative reciprocals

Step-by-step explanation:

th

The statement that best explains the relationship between lines FG and HJ is "They are not perpendicular because their slopes are not negative reciprocals."

The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

To find the slope of a line passing through two given points, we use the formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

For line FG, the two points are F(-4, 1) and G(0, -2):

slope of FG = (-2 - 1) / (0 - (-4)) = (-2 - 1) / 4 = -3/4

For line HJ, the two points are H(-4, -2) and J(0, 4):

slope of HJ = (4 - (-2)) / (0 - (-4)) = 6/4 = 3/2

The slopes of lines FG and HJ are not equal. However, we can see that they are not negative reciprocals of each other:

slope of FG = -3/4

slope of HJ = 3/2

Therefore, lines FG and HJ are not perpendicular because their slopes are not negative reciprocals of each other.

Answer:

y=4/5x-1 is the answer (A)

Step-by-step explanation:

Answer: Step-by-step explanation:

the first one would be your answer (y= 4/5x -1)

because the y intercept is -1 and the rise if 4 and run is 5 and that would be your slope.

Answer:

140°

Step-by-step explanation:

Angles in a triangle add up to 180

we can see it's an isosceles triangle so the base angles are the same

The missing angle inside the triangle would be...

180 - (70 + 70) = 40°

Angles on a straight line add up to 180

so 180 - 40 = 140°

Answer:

164 degrees

Step-by-step explanation:

The measure of the individual internal angle in a polygon is;

(n-2)180/n

n = 22

So we have;

(22-2)180/22

= (20 * 180)/22

= 163.64 degrees

To the nearest whole number, this is 164

Answer:

slope = - 2, point on line = (- 1, 3 )

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = - 2(x + 1) ← is in point- slope form

with slope m = - 2 and (a, b ) = (- 1, 3 )

The slope of equation y−3=−2(x+1) is -2.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

y−3=−2(x+1)

Using Slope- Intercept form

y= mx + b

So, the slope for the equation is -2.

Hence, the slope is -2.

Answer: 1 / 3

Step-by-step explanation:

3/9 of the students in the school choir are fourth graders.

To take a fraction to its simplest form, divide both of the numbers in the fraction by their highest common factor.

3 factors = 1 , 3

9  factors = 1, 3 , 9

Highest common factor = 3

Divide both numbers by 3

= (3/3) / (9/3)

Answer: 8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm

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

Explanation:

To be able to compare these various measurements, all of them must be the same unit. Let's convert each measurement to meters. If the measurement is already in meters, then we'll move onto the next measurement.

Here are some useful conversion factors

With those conversion factors in mind, we get the following conversions:

Here is the summary of the conversions:

The original list of

{900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km}

becomes this equivalent list

{9 m, 8.9 m, 8.95 m, 9.1 m, 12 m, 9.2 m}

in that exact order.

After converting everything to meters, we can then sort the values from smallest to largest. Doing so gets us this sorted list of

{8.9 m, 8.95 m, 9 m, 9.1 m, 9.2 m, 12 m}

Then you convert back each measurement to its original form

{8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm}

which is the final answer.

Answer:

y = -8x - 8

Step-by-step explanation:

Add -8x on both sides to get -y = 8x + 8 and flip the y sign on the left to get your slope function which is y = - 8x - 8.

To graph the function, you would need to put (0, -8) as your y-intercept, and each unit will go down 8 units when you add 1.

Answer:

y=8x+8

Step-by-step explanation:

Just rewrite the problem so it's in y=mx+b format then it's easy to graph

Remember the y intercept is 8 because when x=0  y=8 and the slope is 8 so go up 8 and right 1
