The value of EG is 12
In geometry, the term line segment is defined as the part of a line segment used to join two points in a plane. When segments join the midpoints of two sides of a triangle, the segments are parallel to the other side and represent one half of it.Given equations of line are :
CG = 9x -4
GD = 2x+31
EF = 4x-1
GF = 7
We are asked to find the length of EG. We can start by analyzing the bisector, CD. Since the segment is the bisector, So CG = GD.
CG = GD
9x -4 = 2x+31
7x = 35
x = 5
Analyzing EF
EF = EG + GF
4x-1 = EG +7
20 - 1 -7 = EG
EG = 12
The value of EG is 12

3. Omar runs around the edge of a circular park 6 times every morning. The park has an area of .02 square miles. How far does Omar run each morning?
Answers
Omar runs 0.9577 miles each morning .
Circumference of circle or perimeter of the circle is that the measure of the boundary of the circle whereas the world of circle defines the region occupied by it which is given by A = πr² where "r" is the radius of the circle.If we tend to open a circle and create a line out of it, then its length is that the circumference which is given by C = 2πr where "r" is the radius of the circle.It's typically measured in units, like cm or unit m.It is given that area of the circular park is .02 square miles .
Using area formula , we get
0.02 = πr²
0.02 = 3.14r²
0.0063 = r²
0.079 = r
Omar run each morning = 6 × Circumference of circle

What is a linear function?A linear function is modeled by:

Answers
The supplied statement indicates that the angle of elevation will be = -75 feet.
What is angle of elevation?The term angle of elevation refers to the angle between the horizontal and an object. The line of sight of an observer would be over the horizontal. The term angle of depression refers to the angle between the horizontal and an item. The line of sight of an observer would fall below the horizontal.
In arithmetic, how do you find elevation?"rise over run" is an easy-to-remember equation for calculating a change in elevation as a decimal, which means the rise (the change in vertical distance) divided by that of the run (the change in horizontal distance). As an example, suppose the increase is two and the run is six. So you'd multiply 2 by 6 (or 2/6) to get.
According to the given information:Given The elevation of a sunken ship = 120 feet
the elevation of a submarine = 5/8
So,
Your elevation will be given by employing the MULTIPLICATION OPERATION.

This equation does not hold as 6/5 ≠ 2. Thus, n = 1 doesn't satisfy the given equation and hence is a counterexample.

Let us take n = 1
(1 + 4)² = 1² + 4²

The Density of the given plank with dimensions is; 33.82 kg/m³
How to calculate the density of an Object?We are given;
Length of plank = 2.3 meters
Width of plank = 30 cm = 0.3 m
Height of Plank = 3 cm = 0.03 m
Mass of plank = 0.7 kg
Now, formula for density = mass/volume
Volume of the plank is gotten from the formula;
Volume = Length * width * height
V = 2.3 * 0.3 * 0.03
V = 0.0207 m³
Thus;
Density = 0.7/ 0.0207
Density = 33.82 kg/m³

Answers
Answer:
21 hot dogs
9 pizza slices
Step-by-step explanation:
Given information:
Group = 30 peopleCost of a hot dog = $2.50Cost of a slice of pizza = $3.25Total bill = $81.75Define the variables:
Let x = the number of hot dogs purchased.Let y = the number of pizza slices purchased.Create two equations from the given information:
[tex]\textsf{Equation 1}: \quad x + y = 30[/tex]
[tex]\textsf{Equation 2}: \quad 2.5x+3.25y=81.75[/tex]
Rewrite Equation 1 to make x the subject:
[tex]\implies x=30-y[/tex]
Substitute this into Equation 2 and solve for x:
[tex]\implies 2.5(30-y)+3.25y=81.75[/tex]
[tex]\implies 75-2.5y+3.25y=81.75[/tex]
[tex]\implies 75+0.75y=81.75[/tex]
[tex]\implies 0.75y=6.75[/tex]
[tex]\implies y=9[/tex]
Substitute the found value of y into the rewritten form of Equation 1 and solve for x:

https://brainly.com/question/27034625
Answer:
Number of hot dogs purchased = 21
Number of pizza slices purchased = 9
Step-by-step explanation:
Let the number of people buying hot dogs be represented by the variable H and the number of people buying pizzas be represented by the variable P
Since H hot dogs were purchased and each hot dog costs $2.50, total amount spent on hot dog purchase = $2.50H
Since P slices of pizza were purchased and each slice of pizza costs $3,25, total amount spent on hot dog purchase = $3,25P
Total amount spent (in $) = 2.50H + 3.25P and we are given that this total amount is $81.75
So we have an equation in two variables
2.50H + 3.25P = 81.75 (1)
We know the number of people is 30 and that should equal the number of hot dogs and pizza slices purchased
So
H + P = 30 (2)
Multiply Equation (2) on both sides by 2.50
==> 2.50(H + P) = 2.50 x 30
2.50H + 2.50P = 75 (3)
Subtract equation (3) from equation (1) to eliminate the H terms
(1) - (3):
2.50H + 3.25P - (2.50H + 2.50P) = 81.75 -75
2.50H + 3.25P - 2.50H - 2.50P = 6.75
Collect like terms and simplify
==> (2.50H -2.50H) + (3.25P - 2.50P) = 6.75
==> 0.75P = 6.75
Divide both sides by 0.75
==> 0.75P/0.75 = 6.75/0.75
==> P = 9
So number of people who bought pizza slices = 9
This is the same as the number of pizza slices that were bought
Substitute for P in Eq (2) H + P = 30
==> H + 9 = 30
Subtract 9 from both sides
==> H + 9 - 9 = 30 - 9
==> H = 21
So number of people who bought hot dogs = 21
This is the same as the number of hot dogs purchased

The length of a rectangle is 6 m longer than its width. of the perimeter of the rectangle is 36 m, its area is 72 m².
Any polygon's area is the amount of space it takes up or encloses. The amount of square units that make up the polygon. Because the area is a two-dimensional object, it has both length and width. Typically, the area is expressed in square meters, square feet, or square inches. Acres, hectares, and square kilometers are used to measure the size of larger shapes like cities and farms.
Let l be the length of the rectangle
