Find the area of a sector with an arc length of 40 cm and a radium of 12 cm
The required area of a sector with an arc of 40 cm and a radius of 12 cm is given as 240 cm².
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
Sectoral area = arc / 2 × radius
Sectoral area = 40 / 2 × 12
= 20 × 12 = 240 cm²

what is the measurement of each interior angle in #17
Step-by-step explanation:
Sum of interior angles of a polygon
180°(n−2)
When n=10,
Sum of interior angles of a polygon
180°(n−2)
=180°(10−2)
=1440°
Therefore, Each interior angle of a regular heptagon measures 1440/10=144°

Problem 2
The diagonals of a kite meet at right angles. They also bisect each other. So the two triangles on the left and right side of the kite are congruent.
Because the smaller diagonal is bisected, you need only find the area of 1 of the triangles and double it.
1/2 of the smaller diagonal is the altitude of the triangle. The base is the other larger diagonal.
Solution
Area of the left triangle
Givens
altitude = 7.5
Base = 14 + 5 = 19
formula
Area = 1/2 * B * h
Solution
Area = 1/2 * 19 * 7.5
Area = 71.25
But there are 2 such triangles
Area of both = 71.25 * 2 = 142.5
Answer: A

Suppose that algeria has a workforce of 9,416,534, each of whom earns an average annual salary of (equivalent us dollars) $6,844. if the algerian government wishes to raise $9 billion in tax revenue, approximately where should it set the income tax rate? a. 9% b. 14% c. 18% d. 26% please select the best answer from the choices provided a b c d
The income tax rate is 14% if the Algerian government wishes to raise $9 billion in tax revenue and has a workforce of 9,416,534.
What is the income tax rate?It is defined as the tax rate applied on the solely earned money by a single entity.
Algeria has a workforce of 9,416,534
Each entity average annual salary = $6,844
The raise in tax revenue = $ 9 bilion
To find the income tax rate we must find the total income of the workforce,
= 9,416,534×6844
= $64.45 billion
Now for income tax:
[tex]\rm = \frac{Tax \ revenue}{Total \ income}[/tex]
[tex]=\rm \frac{9 \ billion}{64.45 \ billion}\times 100[/tex]
≈ 14 %
Thus, the income tax rate is 14% if the Algerian government wishes to raise $9 billion in tax revenue.

What is the equation of the line that passes through the point (1, 3) and is perpendicular to the line 2x + 3y = 15?
Answer:
first, we need to know the gradient of the line, 2x+3y=15
Gradient of the line is -2/3
from 3y=-2x+15
Y=-2x/3+5
Step-by-step explanation:
new gradient will be 3/2 since the initial gradient is perpendicular to the new one
therefore, considering the general equation of the line, y-y1=m(x-x1)
where y1=3 and x1=1
we can therefore substitute in the values into the above equation
so, y-3=3/2(x-1)
y-3=3x/2-3/2
2y-6=3x-3
2y-3x=-3+6
2y-3x=3
therefore, the equation of the line perpendicular to line 2x+3y=15 is 3x-2y=-3

What is decision-making?The process of making choice is by identifying the correct decision, gathering information, and assessing alternative solutions.
Marquet is relocating to an area where she will be attending college.
She finds a townhome with an option to rent or buy.

Look at one of the formulas for the perimeter of a rectangle where l represents the length and w represents the width. 2(l + w)
What does the 2 represent in this formula?
Answer:
The question you are asking is a bit unclear but I might be able to offer some insight.
2(l + w) is sometimes used as the formula for the perimeter of a rectangle.
If l represents the length and w represents the width, then the perimeter (sum of the sides) is l + w + l + w.
This simplifies algebraically as 2l + 2w and can be factored into 2(l + w).
So, to find the perimeter of the rectangle you must double the sum of the length and width.

Applying the law of cosines, the measure of angle Y in the image below, to the nearest whole degree, is: B. 64°
What is the Law of Cosine:Law of cosines is given as: y² = x² + z² – 2xz(cosY)
Given the following:
x = 12
y = 16
z = 17
Y = ?
Apply the law of cosines:
16² = 12² + 17² – 2(12)(17)(cosY)
256 = 433 - 408(cos Y)
256 - 433 = -408(cos Y)
