The formula for a sector's area is: 1. A = (sector angle / 360 ) * (pi *r2)
2. A = (sector angle / (2*pi)) * (pi * r2) 3. A = (fraction of the circle) * (pi * r2)
The ratio used to find the area of the sector is that of how to know what fraction of the circle is the sector.
Ratio = (θ/360°)
θ is the angle subtended at the center of the circle by the arc, measured in degrees.
For this question,
θ = 60°
Ratio = (θ/360°) = (60°/360°) = (1/6)
Area of a circle is given as
Area of a circle = πr²
where
π = pi
r = radius of the circle = 8
Area of the circle = πr²
Area of the circle = π (8²) = 64π square units
Area of the sector is given as
Area of the sector = (Ratio) × (Area of the circle)
Ratio = (1/6)
Area of the circle = 64π square units
Area of the sector = (Ratio) × (Area of the circle)
Area of the sector = (1/6) × (64π) = (64π/6) = (32π/3) square units

Which set of numbers can represent the side lengths in inches of an acute triangle 4 5 7 5 7 8 6 7 10 7 9 12?
The correct set of numbers that can represent the sides of an acute triangle among the options given is 5, 7, 8.
To determine if a set of numbers can represent the sides of an acute triangle, we can use the rule that the sum of the squares of the two smallest sides should be greater than the square of the largest side. By applying this rule
it can be seen that set B (5, 7, 8) satisfies this condition and is therefore an acute triangle,
while the other sets do not satisfy this condition and therefore are not acute triangles. It's worth noting that there can be multiple sets of numbers that can represent the sides of an acute triangle.

What is a 3 2 image?
A 3:2 aspect ratio image is a rectangular image where the width is 3 units and the height is 2 units. It means that the width of the image is 1.5 times its height.
This aspect ratio is commonly used in photography, as it is the standard aspect ratio of 35mm film cameras, and also it's used in some digital cameras, DSLRs, and mirrorless cameras.
A 3:2 aspect ratio image can be thought of as a rectangle that has a width of 3 units and a height of 2 units. When you take a picture with a 3:2 aspect ratio, it will have a width that is 50% larger than its height. This allows for a larger view of the subject, and also it is more suitable for landscape images and portrait images.
It's worth noting that other aspect ratios are also used in photography such as 4:3, 16:9, and 1:1, it depends on the camera's sensor and the photographer's preference.

2y – 4x < 8
The solution is the set of all points (x,y) that satisfy the inequality y < 2x + 4.
What is the graph of a function?
The graph of a function is a visual representation of the relationship between the input values (x-coordinates) and the output values (y-coordinates) of the function. In other words, it is a visual representation of the function's rule.
The graph of a function can take many different forms, depending on the function's rule. Linear functions, for example, will produce a straight line on the graph.
To solve the inequality 2y – 4x < 8, we can start by isolating y by adding 4x to both sides:
2y < 4x + 8
then divide both sides by 2:
y < 2x + 4
This is the solution in slope-intercept form (y = mx + b), where the slope is m = 2 and the y-intercept is b = 4.
To graph the solution, you can pick a few x-values and substitute them into the inequality to find the corresponding y-values.
You can use x = -2, x = -1, x = 0, x = 1, x = 2, for example and find the y-values for each x, y < 2* -2 + 4 = 0, y < 2* -1 + 4 = 2, y < 20 + 4 = 4, y < 21 + 4 = 6 and y < 2*2 + 4 = 8.
Then plot those points on a coordinate plane and draw the line that goes through them, and shade the half-plane that is below the line
Hence, the solution is the set of all points (x,y) that satisfy the inequality y < 2x + 4.

In triangle below, angle p is a right angle. Suppose that m angle q =(3x+25) and m angle r = (4x+30).
(A) write an equation to find x. Make sure you use an “=“ sign in your answer.
(B) find the degree measure of each angle.
(A) To find x, we can use the fact that the measures of the angles in a triangle must add up to 180 degrees. So we can write an equation using that information and the measures of angles q and r:
m angle q + m angle r + 90 = 180
(3x+25) + (4x+30) + 90 = 180
so:
7x+45 = 90
7x = 45
x = 45/7 = 5
(B) To find the degree measure of each angle, we can substitute x = 5 back into the expressions for angles q and r.
m angle q = (3x+25) = (3*5+25) = 40 degrees
m angle r = (4x+30) = (4*5+30) = 50 degrees
Since the angle p is a right angle, it has a degree measure of 90 degrees.
So the angle measures are: angle q = 40 degrees, angle r = 50 degrees, angle p = 90 degrees.

What is Mcq, or salvage value?
When an item reaches the end of its useful life, its salvage value—or potential market value—is estimated. It can also be described as the asset's book value after depreciation has been taken into account.
What does the depreciation formula's residual value mean?
The asset's final worth is its residual value. To obtain the entire amount, it is therefore deducted from the starting value. Consequently, we are given the depreciation figure. This sum is divided by the usable years of the asset using the straight-line depreciation technique.
