The perimeter of Ragans new mural is 530cm.
Rectangle:
A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.
Here it is given that the measure of the rectangle is 238 cm and 435cm.
The Raegan creates a mural that is 27cm.
The formula to calculate the perimeter of a rectangle:
Perimeter = 2(length + breadth)
Earlier the length is 238cm and the breadth is 435cm.
Now replace the breath 435cm to 27cm.
length = 238cm
breadth = 27cm
Therefore we get the perimeter of the rectangle:
Perimeter = 2( 238 + 27)
= 2( 265)
=530cm
Therefore the perimeter is 530cm.

The sum of the ages of pam,dion, and their three children, in years, is 5x - 99. where x is dion's age. pam is five years younger than dion. what is the usm of the ages of their children?
The sum of the ages of the children would be 3x - 94 years.
We have the total sum of the ages of pam ,dion and their children
as 5x - 99
here , x is the age of Dion .
we see , pam is five years younger than Dion , so
age of Pam = x - 5
Now as the sum of all the ages = 5x - 99
therefore ,
Age of Dion + Age of Pan + Age of children = 5x - 99
x + x - 5 + Age of children = 5x - 99
2x - 5 + Age of children = 5x - 99
therefore ,
Age of children = 3x - 94
So the age of their children would be 3x - 94 years

The length of segment AE is 5 centimeters. a. what is the length of segment CD? b. what is the length of segment AB? c. Name a segment that had the same length ...
a) The length of segment CD is; CD = 10 cm
b) The length of segment AB is; AB = 5 cm
c) Another segment with same length as segment AB is;
Segment AC
What is the length of the line segment?From the attached image, we see that Segment AE is a radius of the circle with center of A.
Now, any segment with origin from the center of the Circle that goes on to hit the circumference of the circle, is also a radius, and would be equal in length to segment AE.
a) Segment CD divides the circle into 2 equal parts and as such it will be the diameter of the circle.
Diameter = 2 × radius.

Isabel works 180 hours in one month.what is her average hourly wage,in dollars,to meet the budget?round to the nearest cent
One method is to determine the average hourly rate for all employees, regardless of where they work in your company, what they do, or how many hours they work.
How to Calculate the Average Hourly Rate for Employees ?To begin, calculate the total number of hours worked by multiplying the number of weeks in a year by the number of hours worked per week. Divide this figure by the annual salary. For example, if an employee earns $50,000 per year and works 40 hours per week, his or her hourly rate is $50,000/2,080 (40 x 52) = $24.04.
When budgeting for future projects, keep in mind that if you pay Bill $18 per hour, Lisa $16, and Hank and Jake $14, your labor costs will vary depending on who you send to the job site.
However, if you can use Bill less frequently each week and Hank or Jake more frequently, you might be able to budget for next month using the $15.82 per hour figure.

Two planes are parallel and each plane contains a line. Are the two lines skew? Explain your reasoning.
If Two planes are parallel and each plane contains a line, the two lines are not skew because In the event that any two lines fall on a single plane, they will either intersect or be parallel to one another. Both instances violate the concept of a skew line because the skew lines are neither parallel nor intersect.
Do two parallel lines on a plane have a skew?Infinitely many lines cross through, yet only one of them is parallel to. Lines that never intersect and are in distinct planes are known as skew lines. Parallel lines and skew lines are distinguished by the fact that they both reside in the same plane, whereas skew lines do not.
The two lines would overlap at some point if the two planes on which they are located weren't parallel, which again defies the definition of skew lines.
Therefore, The skew lines are thus present if and only if both lines fall on a pair of parallel planes.

Find the equation of the linear function represented by the table below in slope-
intercept form.
The equation of the linear function is represented by the table given in the slope-intercept form is y = x -1.
What is an equation of a line?
A line's equation is a single representation of all of the line's points. The general form of a line equation is ax + by + c = 0, and each point on the line satisfies this equation. The slope of the line and a point on the line are the two necessary components to create the equation of a line.
The equation of a line, in the slope-intercept formula:
y = mx + b
In which,
m is the slope, that is, how much y changes when x changes by 1.
b is the y-intercept, that is, the value of y when x = 0.
Given two points (x,y), the slope is the change in y divided by the change in x.
We have points (-1, -2) and (1, -4).
[tex]m = \frac{(-2 - (-4))}{1 - (-1)}[/tex]
m = 1;
Then,
y = 1x + b
Point (-1,-2) means that when x = -1 and y = -2, we use this to find b.
y = 1x + b
-2 = 1(-1) + b
b = -2 + 1
b = -1
Thus,
y = x -1.
Hence, the equation of the linear function is represented by the table given in the slope-intercept form is y = x -1.

Answer:
The side of the triangle is 14 in======================
Let the sides be t for triangle and s for square.
Difference of perimeters3t = 4s + 10Difference of sidest = s + 6Rearrange the second equations = t - 6Substitute this into first equation and solve for t3t = 4s + 103t = 4(t - 6) + 103t = 4t - 24 + 103t = 4t - 144t - 3t = 14t = 14Answer:

Step-by-step explanation:
The side lengths of an equilateral triangle are the congruent.
The side lengths of a square are the congruent.
Let x be the length of one side of the equilateral triangle.
⇒ Perimeter of triangle = 3x
Let y be the length of one side of the square.
⇒ Perimeter square = 4y

[tex]\begin{cases}3x = 4y + 10\\x = y + 6\end{cases}[/tex]
Substitute the second equation into the first equation and solve for y:
[tex]\implies 3(y+6)=4y+10[/tex]
[tex]\implies 3y+18=4y+10[/tex]

26.2% is the total percent of discount offered by the merchant.
Let us assume that each item is $100.
As it is given that 18% is off, we have an amount after off is:
Amount after 18% off = 100 × (100 - 18)/ 100
= 100 × 0.82
= 82
Next, there is 10% off
So the amount become = 82 ×( 100 - 10) / 100
= 82 ×0.9
= 73.8
So the final price of an item is $73.8

The solution of the linear equation:
(2x + 6)/5 = 4x - 3
is x = 7/6
How to solve the equation?
Here we have the following equation:
(2x + 6)/5 = 4x - 3
To solve this, we need to isolate x in one of the sides of the equation, we can start by multiplying both sides by 5.
2x + 6 = 5*(4x - 3)
Expanding the right side we get:
2x + 6 = 20x - 15
Now you can see that this is a simple linear equation, now we need to group like terms:
6 + 15 = 20x - 2x
21 = 18x
Now we can divide both sides by 18 to get:
21/18 = x
Finally, if we divide both numerator and denominator of the fraction by 3, we get:
21/3 = 7
18/3 = 6
Then 21/18 = 7/6
