A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The length of GF is 254 units.
What is a triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.
Since a centroid of a triangle divides the median into a ratio of 2:1. Therefore, the ratio of AG: DG is,
AG / DG = 2/1
(19x+14)/(9x+20) = 2/1
19x + 14 = 18x + 40
19x - 18x = 40 - 14
x = 26
Assuming the triangle is an equilateral triangle, therefore, the length of GF will be,
GF = DG = 9x+20
GF = DG = 9(26) + 20
GF = 254 units
Hence, the length of GF is 254 units.

two plus that number equals a dozen, so we can write it like this:
2 + n = 12
subtract 2 from both sides
n = 10.
the number is 10
The number is 5 if two increased by a number is a dozen. In other words, the correct answer is 5 by solving equations.
Step 1: Write the given information as an equation. "Two increased by a number" can be represented as 2 + x, where x is the unknown number.
Step 2: Translate "Two increased by a number is a dozen" into an equation. The word "a dozen" refers to the number 12.
[tex]2 + x = 12.[/tex]
Step 3: Solve the equation for x. To isolate x, subtract 2 from both sides of the equation:
[tex]2 + x - 2 = 12 - 2.[/tex]
This simplifies to x = 10.
Step 4: Verify the solution. Substitute the value of x back into the original equation:

2/5 (1/3x - 15/8) - 1/3(1/2 - 2/3x)
Answers
Your question presented was: [tex]\frac{2}{5} (\frac{1}{3} x-\frac{15}{8} )-\frac{1}{3} (\frac{1}{2} -\frac{2}{3}x)[/tex]
Okay, lets distribute this problem and break it into two parts. We will distribute 2/5 and -1/3 to the numbers in parenthesis. This is the distributive property.
Step 1.
[tex]\frac{2}{5} (\frac{1}{3} x-\frac{15}{8} )[/tex] when distributed is [tex]\frac{2}{15} x - \frac{30}{40}[/tex]
Please note that -1/3 can be rewritten as + -1/3. So you must distribute the negative.
Step 2.
[tex]\frac{-1}{5} + \frac{2}{9} x[/tex]
So..lets put the 2 parts of the equation together
[tex]\frac{2}{15} x - \frac{30}{40}[/tex] + [tex]\frac{-1}{5} + \frac{2}{9} x[/tex] can be simplified by getting the common denominator.
You can only add like terms, so those fractions with x can only be combined with x.
Step 3.
Lets reformat while we're at it
[tex]\frac{6}{45} x + \frac{10}{45} x -\frac{30}{40} -\frac{8}{40}[/tex]
We got 45 because the LCM (Lowest Common Multiple) of 15 and 9 was 45. We multiplied both sides of the fraction by 3 for 2/15x and we multiplied by 5 on both parts of the fraction for 2/9x.
Now we combine.
Step 4.
[tex]\frac{16}{45}x-\frac{38}{40}[/tex]. We can still simplify!
Step 5.
-38/40 can be simplified by a common factor, 2! So our final answer is
[tex]\frac{16}{45}x-\frac{19}{20}[/tex]

A condition is given that a line passes through the points whose coordinates are (1,5) and (4,11).
It is asked to find the linear equation which satisfies the given condition.
Step 1 of 2
Determine the slope of the line.
The points through which the line passes are given as (1,5) and (4,11). Next, the formula for the slope is given as,
[tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]
Substitute 11&5 for [tex]$y_{2}$[/tex] and [tex]$y_{1}$[/tex] respectively, and [tex]$4 \& 1$[/tex] for [tex]$x_{2}$[/tex] and [tex]$x_{1}$[/tex] respectively in the above formula. Then simplify to get the slope as follows,
[tex]$$\begin{aligned}m &=\frac{11-5}{4-1} \\m &=\frac{6}{3} \\m &=2\end{aligned}$$[/tex]
Step 2 of 2
Write the linear equation in point-slope form.
A linear equation in point slope form is given as,
[tex]$$y-y_{1}=m\left(x-x_{1}\right)$$[/tex]
Substitute 2 for [tex]$m, 1$[/tex] for [tex]$x_{1}$[/tex], and 5 for [tex]$y_{1}$[/tex] in the above equation and simplify using the distributive property as follows,
[tex]$$\begin{aligned}&y-5=2(x-1) \\&y-5=2 x-2 \\&y=2 x-2+5 \\&y=2 x+3\end{aligned}$$[/tex]
This is the required linear equation.
Two cyclists start at the same time from opposite ends of a course that is 45 miles long. One cyclist is riding at 14 mph and the second cyclist is riding at 16 mph. How long after they begin will they meet
Answers
If the distance is 45 miles and speed of both cyclist is 14 and 16 miles per hour then they will take time of 1.5 hour to meet.
Given First cyclist is riding at 14 miles per hour and second at 16 miles per hour. The distance is 45 miles.
We know that speed is the distance covered by an object in a particular period of time.
Speed=distance/time.
It is expressed as kilometers per hour or miles per hour, etc.
If both riders are riding towards each other then the speed will be 16+14 =30 miles per hour.
Distance=45 miles.
Time =distance/speed
=45/30

The interquartile range of the data set is 21.
Given that the heart rate of 10 adults is measured and the results are 83, 87, 90, 92, 93, 100, 104, 111, 115, 121.
The interquartile range shows the extent of the middle half of the distribution. Quartiles segment any distribution, ordered from low to high, into four equal parts. The interquartile range (IQR) contains the second and third interquartile ranges, the central half of the dataset.
The value of quartile 1 is Q₁=90
The value of quartile 3 is Q₃=111
So, the interquartile range is
IQR=Q₃-Q₁
IQR=111-90
IQR=21

[tex]3y-13\geq -9[/tex]
Add 13 to both sides:
[tex]\implies 3y-13+13\geq -9+13[/tex]

Add 13 to both sides:
[tex]\implies 3y-13+13\leq -1+13[/tex]
[tex]\implies 3y\leq 12[/tex]
Divide both sides by 3:
[tex]\implies \dfrac{3y}{3}\leq \dfrac{12}{3}[/tex]

What is the expression of g(x) when we perform the following sequence of transformations onto the parent function fx=x2+2x:
a) Compress horizontally by a factor of 3 with respect to its axis of symmetry
b) Shift right 1 unit
Answers
The transformed function is:
[tex]g(x) = ( (x + 1)/3 - 2)^2 + 2*( (x + 1)/3 - 2)[/tex]
How to get the function g(x)?
The parent function is:
[tex]f(x) = x^2 + 2x[/tex]
Here the axis of symmetry is at:
[tex]x = -2/2*1 = -1[/tex]
So first we need to apply a horizontal compression by a factor of 3 with respect to the line x = -1.
Here we can, for the moment, define a new variable that is zero when x = -1, let's define:
z = x + 1.
x = z - 1
Writing our function in terms of z, we get:
[tex]f(z) = (z - 1)^2 + 2*(z - 1)[/tex]
Now we can apply a compression by a factor of 3 around the origin. Then we have:
[tex]f(z/3) = (z/3 - 1)^2 + 2*(z/3 - 1)[/tex]
Returning to the original variable, we have:
[tex]f((x+1)/3) = ( (x + 1)/3 - 1)^2 + 2*( (x + 1)/3 - 1)[/tex]
Now we want to shift it one unit to the right, then we have:
g(x) = f( (x + 1)/3 - 1)
Replacing the actual function we get:
[tex]g(x) = f((x+1)/3 - 1) = ( (x + 1)/3 - 1 - 1)^2 + 2*( (x + 1)/3 - 1 - 1)\\\\g(x) = ( (x + 1)/3 - 2)^2 + 2*( (x + 1)/3 - 2)[/tex]

The equation of the parabola in standard form whose vertex is (0, 0) and a focus along the negative part of the x-axis is equal to x² = - 6 · y. (Correct choice: D)
How to determine the best equation of the parabola based on given characteristics
In accordance with the statement, we find that the parabola has its vertex at the origin, therefore it is horizontal and its vertex constant (C) is negative as its focus is in the negative part of the x-axis. Therefore, the equation of the parabola in standard form has the following form:
x² = C · y, for C < 0. (1)
In consequence, the equation of the parabola in standard form whose vertex is (0, 0) and a focus along the negative part of the x-axis is equal to x² = - 6 · y.

Two farmers bought a total of 230 cows and a year later found out that the first farmer had 10% more cows than in the beginning, whereas the second had 20% increase. The total number of cows at the end of the observed period was 263. How many cows did each have in the beginning?
Answers
In the beginning, they have 50 and 180 cows respectively.
How to find the total number of cows?The two farmers bought a total of 230 cows .
A year later the first farmer had 10% more cows than in the beginning.
Therefore,
let
x = number of cow he has initially.
A year later the percentage increase = 0.1x
whereas the second had 20% increase. Therefore,
let
y = number of cow he has initially.
A year later percentage increase = 0.2y
Hence,
x + y = 230
1.1x + 1.2y = 263
1.1x + 1.1y = 253
1.1x + 1.2y = 263
0.2y = 10
y = 10 / 0.2
y = 50
x = 230 - 50
x = 180

4. Write the trinomial represented by each rectangle of algebra tiles. Then, determine the
dimensions of each rectangle
Answers
The trinomial represented by the algebraic tiles is x^2 + 4x + 3
How to determine the trinomial?On the horizontal axis, we have:
1 row under the big square.
This represents x + 1
On the vertical axis, we have:
3 columns beside the big square.
This represents x + 3
So, we have:
(x + 1) * (x + 3)
Expand
(x + 1) * (x + 3) = x^2 + x + 3x + 3
Evaluate
(x + 1) * (x + 3) = x^2 + 4x + 3
Hence, the trinomial represented by the algebraic tiles is x^2 + 4x + 3
