Answer:

Ya I think your right

Step-by-step explanation:

A reasonable estimate for how long the job will take if she has her two sons help if they each work at approximately the same rate as Astrid is  5.75 hours.

Outside of her cabin, Astrid is painting. She is aware that if she works alone, the task will take her 23 hours to finish. If her two boys labor at roughly the same rate as Astrid, a fair estimate of how long the job will take with their assistance is

Astrid is painting the outside of her cabin = 23 hours

Astrid has her two sons help if they each work at approximately the same rate as Astrid is 23/2 = 11.5

Then 11.5/2 = 5.75 hours.

The work is calculated using the work formula. Let's review what work means before learning the formula. When we apply a force to an item and the object is moved, we say that work has been done. The work done becomes zero if there is no displacement in the direction of the force. Calculating the amount of labor required to move an object is done using the work formula.

Given that,

Outside of her cabin, Astrid is painting. She is aware that if she works alone, the task will take her 23 hours to finish.

We have to find If her two boys labor at roughly the same rate as Astrid, a fair estimate of how long the job will take with their assistance is.

Astrid is spent 23 hours painting the outside of her cabin.

If each son works at roughly the same rate as Astrid, which is 23/2 = 11.5 she asks her two sons to assist.

Then 11.5/2 = 5.75 hours.

Therefore, If her two boys labor at roughly the same rate as Astrid, a fair estimate of 5.75 hours long the job will take with their assistance is.

The line A has the constant of proportionality between x and y as 5.

In mathematics, we use the constant of proportionality to determine the type of proportionality, whether direct or indirect.

For, the data given in the question;

Given lines A, B, and C Obtaining the equation for the line yields the proportionality constant.

1) Line A intersects (0,0) and (1, 5). Line A's equation is given by:

y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)

Substitute the values;

y - 0 = [(5 - 0)/(1 - 0)]×(x - 0)

y = 5x

y/x = 5

The proportionality constant between y and x is 5.

2) Line B traverses (0,0) and (3, 5). Line A's equation is given by:

y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)

Substitute the values;

y - 0 = [(5 - 0)/(3 - 0)]×(x - 0)

y = 5x/3

y/x = 5/3

The proportionality constant between y and x is 5/3.

3) Line C intersects (0,0) and (3, 2). Line A's equation is given by:

y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)

Substitute the values;

y - 0 = [(3 - 0)/(2 - 0)]×(x - 0)

y = 3x/2

y/x = 3/2

The proportionality constant between y and x is 2/3.

Therefore, the constant of proportionality between x and y as 5 shown by line A.

Answer: 1 and 3 dont 2 and 4 do have a line of symmetry

Step-by-step explanation:

Graphs 1, 3 function are not line symmetry and 2 and 4 have line symmetry.  

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The line of symmetry is an imaginary line that runs through the centre of a line or shape creating two perfectly halves.

To check a function to be symmetrical about the origin we need to replace y with minus y and x with minus x and the function must be equal to original function.

In the given graphs, 1 and 3 are not symmetrical and 2 and 4 are symmetrical.

Hence graphs 1, 3 function are not line symmetry and 2 and 4 have line symmetry.

Answer:

all angles are 60 degrees

Step-by-step explanation:

since all sides are equal, all angles will be equal so its a equilateral triangle

all angles in a equilateral triangle are 60 as 180/3 is 60

so all angles equal 2x

2x = 60

x = 60/2 = 30

Answer:

  small: 1 liter; large: 7.5 liters

Step-by-step explanation:

The difference between the two sets of buckets is 2 small buckets and 2 liters. Hence we know that a small bucket is 1 liter.

Then 5 small buckets contribute 5 liters to the 20-liter total. The remaining 15 liters comes from 2 large buckets, so each of those is 7.5 liters.

Large bucket: 7.5 liters

Small bucket: 1 liter
