Find the scale factor of PQRS to JKLM and the values of w, x, and y.

Answers

D cause Times x by y and your answer should be

The scale factor of PQRS to JKLM is 4/5 and the values of w, x and y are 20, 12.5 and 20 respectively.

What is Scale Drawing?

A scale drawing is a drawing made by enlarging or reducing the size of the original object.

The factor by which the drawing is enlarged or reduced is called the scale factor.

Given two quadrilaterals PQRS and JKLM.

Since the shape is similar, the angles are equal and thus are similar figures.

The corresponding sides of two similar figures are proportional.

Scale factor of PQRS to JKLM = QR / KL = 12 / 15 = 4/5

Using the proportional rule for similar figures,

KL / QR = LM /RS  = MJ / SP = JK / PQ

15 / 12 = x / 10 = y / 16 = 25 / w

Scale factor = 15/12 = 5/4

Consider 15 / 12 = x / 10.

12x = 150

x = 12.5

Consider 15 / 12 = y / 16

12y = 15 × 16

y = 20

Consider 15 / 12 = 25 / w

15w = 12 × 25

w = 20

Hence the option d is the correct answer.

Find slope
11x - 6y = -36

Answers

Answer:

11/6

Step-by-step explanation:

To isolate the y on one side of the equation, you must first subtract 11x from both sides. Then the equation becomes -6y = -11x - 36.

Then you must divide both sides by -6 to isolate the y. The coefficient of the variable x becomes -11/-6, which is just 11/6.

Given the graph below, what is the average rate of change between 1 year and 4 years
of age?

Answers

Answer : The average rate of change between 1 year and 4 years  of age is 7.33 lbs per year.

Step-by-step explanation :

As we know that the average rate of change between two input values is the total change of the output values divided by the change in the input values.

From the table, we conclude that:

The weight of 1 year of age = 20 lbs

The weight of 4 years of age = 42 lbs

Now we have to determine the average rate of change between 1 year and 4 years  of age.

The input (years) has changed by = 4 years - 1 year = 3 years

The output has changed by = 42 lbs - 20 lbs = 22 lbs

Average rate of change = Output ÷ Input

Average rate of change = [tex]\frac{22\text{ lbs}}{3\text{ years}}[/tex]

Average rate of change = 7.33 lbs per year

Therefore, the average rate of change between 1 year and 4 years  of age is 7.33 lbs per year.

A standard train ticket in a certain city costs $1.50 per ride. People who use the train also have the option of purchasing a frequent rider pass for $17.25 per month. With the pass, a ticket costs only $0.75 per ride. How many train rides a month make the frequent rider pass a better deal than standard train tickets?

Answers

Just off the bat 17$is 12 rides and then 17.25 +0.75 is 18 so 13 rides

x = number of rides per month.

Without the pass, the cost per ride is 2.00 per ride.

With the pass, the cost per ride is 1.25 per ride plus 15.75 per month.

You want to know at what number of rides does the cost per ride using the pass become cheaper than the cost per ride without using the pass.

The formula for total cost is as follows:

without the pass:

C1 = 2*x

with the pass:

C2 = 15.75 + 1.25*x

You want to know when C2 becomes less than C1.

C2 < C1 is the inequality equation you are looking for.

Since C2 = 15.75 + 1.25*x, and C1 = 2*x, this equation becomes:

15.75 + 1.25*x < 2*x

Subtract 1.25*x from both sides of this equation to get:

15.75 < 2*x - 1.25*x which becomes:

15.75 < .75*x

Divide both sides of this equation by .75*x to get:

15.75/.75 < x

Simplify to get:

21 < x

21 < x is the same as x > 21.

Your answer is the C2 becomes cheaper than C1 when x > 21.

If you make x = 21, then:

C1 = 2*21 = 42
C2 = 15.75 + 1.25*21 = 15.75 + 26.25 = 42

They are equal.

If you make x = 22, then:

C1 = 2*22 = 44
C2 = 15.75 + 1.25*22 = 15.75 + 27.5 = 43.25

43.25 is cheaper than 44 so C2 is cheaper than C1, confirming that the equation is good.

Emily wants to buy new boots that cost $68. The sales tax rate in her city is 512% . What is the total cost for the boots?

Answers

Answer:

$71.74

Step-by-step explanation:

<3

The total cost for the boots after the sales tax of 5.12% will be $71.48.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

Emily wants to buy new boots that cost $68. The sales tax rate in her city is 5.12%.

Let x be the total cost for the boots. Then the total cost for the boots will be given as,

x = (1 + 5.12%) × $68

x = (1 + 0.0512) × $68

x = 1.0512 × $68

x = $71.48

The total cost for the boots after the sales tax of 5.12% will be $71.48.
