The number of hours taken by Meredith to edit a textbook if she works alone is 20 hours and time taken by Phil alone to edit text book is 60 hours..

Given that, Phil and Meredith work for a book publisher editing mathematics textbooks.

The basic concept of Time and Work is similar to that across all Arithmetic topics, i.e. the concept of Proportionality. Efficiency is inversely proportional to the Time taken when the amount of work done is constant.

Let the time taken by Meredith be x.

Phil has less experience and takes three times​ as long as Meredith to edit a textbook.

So, time taken by Phil be 3x.

Now, 1/x +1/3x =1/15

⇒ (3+1)/3x =1/15

⇒ 4/3x =1/15

⇒ 4/x =1/5

⇒ x=20 hours

So, time taken by Phil =3x =60 hours

Therefore, the number of hours are 60 hours.

The equation of the line that passes through the points (2, 1 ) and (4,5) in the Cartesian coordinate plane is y = (2/3)(x - 4) + 5.

By subtracting the y coordinates [5 - 1] = 4, we get

Subtract the x coordinates in the same order  [4 - (-2)]  = [4 + 2] = 6

The slope is given by  y-coordinate/x-coordinate = 4/6  = 2/3.

Now, just choose one point say (4,5), and substitute the coordinates in this formula-

y - [y-coordinate of our point] - (slope)* [ x - ( the  x-coordinate of our point)]

y - 5  = (2/3)(x - 4)      ...........(adding 5 to both sides)

y = (2/3)(x - 4) + 5    

Hence, the equation of the line in the "slope-intercept" form is y = (2/3)(x - 4) + 5.

Answer: im not exactly sure but i think 600,000m³

Step-by-step explanation: multiply 50,000m by 4 to get 200,000m and then multiply that by 3 (because 200,000 is only one section of the tunnel)

and by doing that you get 600,000m and then add cubed onto the end because it says cubic meters

Clio went 20 times to the movies last year. This can be calculated using linear equations.

Given,

Number of times all together they went to movies = 30

Clio = 5 times more than Alex

Bernie = is 2 times more than Alex.

Let 'a' be the number of times Alex has gone to the movie:

Clio = 5a

Bernie = a + 2

So, we can calculate the number of times Clio went to the movies if we find out how many times Alex went. This can be calculated using the following linear equation:

Clio + Bernie + Alex = 30

5a + (a +2) + a = 30

7a + 2 = 30

7a = 30 - 2

7a = 28

a = 28 ÷ 7

a = 4 times

From solving the above equation, we got that Alex (a) went to the theatre 4 times last year. Now, substituting the value of 'a' we get:

Clio = 5a

Clio = 5*4 = 20 times

Bernie = a+2 = 4+2 = 6 times

So, we can conclude by saying that, Clio went 20 times to the movies last year.

Yes , Dilation do changes the position

Dilation is the process of changing the size or shape of an object. With the aid of the specified scale factor, it is a transformation that makes the objects smaller or larger.

The pre-image is the original figure before dilation, while the new figure is referred to as the image.

Dilation can be of two types:

Dilation does not change the shape of the object from preimage to image only size and position are changed.

The shape can be a point, a line segment, a polygon, etc. It should be noted that the shape can be enlarged or shrunk but the proportion of each dimension of the shape and the angles remain the same.

Hence , It is true that dilation changes the position

Answer:

101.25

Step-by-step explanation:

To find the number of students, we need to first determine the total amount earned from the students. We can do this by multiplying the number of people by the cost per student: $3/student * 120 people = $<<3*120=360>>360.

Since the total amount earned was $435 and we know that $360 of that came from students, we can find the number of students by subtracting the total earned from students from the total amount earned: $435 total - $360 from students = $75 from adults.

Since the cost per adult was $4, we can divide the total amount earned from adults by the cost per adult to find the number of adults: $75 / $4/adult = <<75/4=18.75>>18.75 adults.

Since there were 120 people in total and 18.75 of them were adults, there must have been 120 people - 18.75 people = <<120-18.75=101.25>>101.25 students

The scale factor from the pre-image to the image is 2/5.

Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller. This transformation produces an image that is the same as the original shape. But there is a difference in the size of the shape.

let the scale factor be m, so that the scale factor multiplied by the dimension of pre-image should give dimension of image.

so that we have,

20 x m = 8

20m = 8

divide both sides by 20

m = 8/20

m = 2/5

The equation used to represent the distance between two points A and B is AB  =  x Cos 28°

The equation can be defined as a mathematical statement made up of expressions. The length of the line that connects two points is known as the distance between the two points. A triangle is a closed shape with 3 sides, 3 angles and 3 vertices. Triangle is a 2- dimensional figure.

As per the given question,

Let the hypotenuse be x

The two points A and B are on the base of the triangle so,

Base - length = AB

The distance between the two points is

⇒   cos Θ   =   base / hypotenuse

where,      base = AB

                hypotenuse = x

⇒   cos Θ   =   AB / x

⇒   AB   =   x cos Θ      →   1

Substitute Θ  =  28 in 1,

⇒   AB = x cos 28°

Therefore, AB = x cos 28° is the equation used to represent the distance between two points A and B.

By using tangent chord angle formula, the measure of angle FGH is 50°.

What is tangent chord angle?
The angle formed by the chord in the alternate segment is equal to the angle formed by the tangent through the point of contact of the tangent for any circle, according to the theorem.

Another name for the tangent-chord theorem is the alternate segment theorem.
We have to find the m ∠FGH.
Since, by tangent - chord angle theorem, the measure of a tangent-chord angle is twice the measure of the intercepted arc inside the angle.
GH = 2(m ∠FGH)⇒ m ∠FGH = 1/2(GH)
Here GH = 100° ⇒ m ∠FGH = 1/2(100°) m ∠FGH = 50°
Hence, by using tangent chord angle formula, the measure of angle FGH is 50°.
