Answer: [tex]n=8[/tex]
Cross-multiply
[tex]2/3=n/12[/tex]
[tex](2)*(12)=n*(3)[/tex]
[tex]24=3n[/tex]
Flip the equation
[tex]24=3n---->3n=24[/tex]
Divide both sides by 3
[tex]3n/3=24/3[/tex]
[tex]24/3=8----> n=8[/tex]
Final answer:
To solve the proportion 2/3 = n/12, cross multiply to get 2×12 = 3×n. Simplify the equation to 24 = 3×n, and divide both sides by 3 to get n = 8.
Explanation:
To solve the proportion 2/3 = n/12, you begin by cross multiplying to find the value of n. This means you multiply 2 by 12 and 3 by n. The equation now looks like this: 2×12 = 3×n.
Next, simplify the left side of the equation, which results in 24 = 3×n.
Finally, solve for n by dividing both sides of the equation by 3, leading to n = 8.
This method of cross multiplication and division is a common technique used to solve proportions and find missing values in ratios.

Step-by-step explanation:
Graph f(x)=(x−2)(x−6) .
Use the parabola tool then choose the vertex followed by one point on the parabola.
Here is the graph for the equation
Given function to be graphed is,
f(x) = (x - 2)(x - 6)
We will convert the equation of the function into the vertex form,
(x - 2)(x - 6) = x(x - 6) - 2(x - 6)
= x² - 6x - 2x + 12
= x² - 8x + 12
= x² - 2(4x) + 16 - 4
f(x) = (x - 4)²- 4
By comparing this equation with the vertex form of the equation of a parabola,
g(x) = a(x - h)² + k
Here, (h, k) is the vertex of the parabola.
Therefore, vertex of the function 'f' will be (4, 4).
Now we will find the x-intercepts and y-intercept of the function.
For x-intercept, put f(x) = 0
0 = (x - 4)²- 4
(x - 4) = ±2
x = 4 ± 2
x = 2, 6
Therefore, x-intercepts of the function are (2, 0) and (6, 0).
For y-intercept, put x = 0
f(0) = (0 - 2)(0 - 6)
f(0) = 12
Therefore, y-intercept of the function is (0, 12).
By plotting these ordered pairs and joining them by a curve we can get the graph of the parabola.

What is the x value for the solution -x+2y=6
6y =x+18
For the given set of equations, x = 0 and y = 3.
Step-by-step explanation:
Step 1:
From the question,
[tex]-x + 2y = 6[/tex], take this as equation 1,
[tex]6y =x+18, x - 6y = -18[/tex], take this as equation 2.
Step 2:
When we add equation 1 and equation 2, the x variable is canceled out and y can be calculated.
[tex]-4y = -12, y = \frac{-12}{-4}, y = 3.[/tex]
Step 3:
Substituting this value of y in any of the previous equations we will get x's value.
Here this value of y i.e y = 3 is substituted in equation 1.
[tex]-x + 6 = 6, -x = 6 -6, -x=0, x=0.[/tex]
So we have x = 0 and y = 3.

Step-by-step explanation:
4) 416 = 2x² - 6x
2x² - 6x - 416 = 0
x² - 3x - 208 = 0
x² - 16x + 13x - 208 = 0
x(x - 16) + 13(x - 16) = 0
(x - 16)(x + 13) = 0
x = 16, -13(not possible)
So 16 rows

In the figure below, ABO and GOF are right triangles. How would you represent the area of the shaded region?
1. r^2 (π-1)
2. r^2 (π+1)
2. r^2 (π-1/2)
3. r^2 (1-π)
Answer:
option 1
Step-by-step explanation:
The shaded area is area of circle - area of 2 congruent triangles
area of circle = πr²
Note that the base and height of both triangles is the radius
Area o triangle = [tex]\frac{1}{2}[/tex] × r × r = [tex]\frac{1}{2}[/tex]r²
area of 2 triangles = 2 × [tex]\frac{1}{2}[/tex] × r² = r²
area of shaded region = πr² - r² = r²(π - 1) → (1)
To represent the area of the shaded region in the figure, use the expression "r² (π+1)" as it closely approximates the calculation for the shaded area.
In the figure described, ABO and GOF are right triangles, and there's a shaded region within these triangles. To represent the area of the shaded region, we can consider the difference between the areas of the larger triangles ABO and GOF and the smaller semicircles centered at O within each triangle.
The area of a triangle is given by (1/2) × base × height, and the area of a circle is πr², where "r" is the radius.
Calculate the area of ABO: (1/2) × AB × AO
Calculate the area of GOF: (1/2) × GO × GF
Calculate the area of one semicircle: (1/2) × πr²
Now, to find the area of the shaded region, subtract the sum of the areas of the two semicircles from the sum of the areas of the two triangles:
Shaded Area = (ABO - πr²) + (GOF - πr²)
So, the representation for the area of the shaded region is:
Shaded Area = (1/2) × AB × AO + (1/2) × GO × GF - πr²
Therefore, option 2, "r² (π+1)," is the closest representation of the area of the shaded region.

Answer: 1) 1 1/2, 2 1/4, and 4
Step-by-step explanation: 1) We know that the equation would be the cups of flour being multiplied by the batches. Like, 5 times 3/4 would equal 15/4 which would simplify to 3 3/4.
So, to find the first missing number, we do 2 x 3/4, which equals 6/4( 1 1/2).
The next missing number would be 3, because we're going in order-- like 1, 2, 3, 4. So we do 3 x 3/4.
We then don't have a number for batches this time. So we still do, 3/4 x 3 but this time we cross out both the 3 on the top and we're left with 4, our answer.

Maria put trim around a banner that is the shape of a triangle. Each side is 22 inches long. Maria has 1/2foot of trim left. What was the length of the trim when she started? Write your answer in yards
Maria had 2 yards of trim when she started.
Step-by-step explanation:
Step 1:
All of the sides of the triangle is 22 inches long each.
The total length of the sides of the triangle [tex]= 3(22) = 66.[/tex]
So the total length of the trim for the banner is 66 inches long.
If Maria still has [tex]\frac{1}{2}[/tex] a foot of trim left, she had 6 inches of the trim left.
The length of the trim when she started[tex]=66 +6 = 72[/tex] inches.
Step 2:
Now we need to convert the 72 inches into yards.
We have 1 inch = 0.0277778 yards.
So 72 inches [tex]= 0.0277778(72) = 2.[/tex]
So Maria had 2 yards of trim when she started.

Given that,
For a game, Tony has a rectangle drawn on a piece of paper that has an area of 18 in.^2
In order to have a similar rectangle that's area is only 2 in.^2
Thus, we need to find the scale factor
Let "c" be the scale factor
Let "x" be the area of original rectangle
Let "y" be the area of dilated rectangle
Therefore,
[tex]c = \frac{y}{x}\\\\c = \frac{2}{18}\\\\c = \frac{1}{9}[/tex]
