Answer:

2.50x + 3.75y = 33.75

Step-by-step explanation:

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.

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.

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

Answer:

17.4 ft²

Step-by-step explanation:

The formula to find the area of a triangle:

1/2 x b x h, where b is the base and h is the height.

1) Substitute the given values into the formula and solve it.

= 1/2 x 6 x 5.8

= 1/2 x 34.8

= 17.4

Answer:

Area= 17.4 ft²

Step-by-step explanation:

The formula of the area of any triangle is given by: A = [tex]\frac{b*h}{2}[/tex]

where A: area of the triangle

           b: base of the triangle

           h: height of the triangle

in this figure we have:

b= 6ft

h= 5.8ft

A= [tex]\frac{6 * 5.8}{2}[/tex] = [tex]\frac{34.8}{2}[/tex]=17.4 ft²

The required area of a sector with an arc of 40 cm and a radius of 12 cm is given as 240 cm².

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

Remark

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

Problem 3

Remark

The way they have given you the problem, you could be easily fooled. The 2 does not help you at all.

The total cost for five years of her rent is less than she buys the townhome. Then the correct option is C.

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.

The conditions of each are shown below.

rent: move-in cost of $1,350 and monthly payment of $795.

buy: move-in cost of $8,235 and monthly payments of $750.

Marquet plans to stay in the area for the 5 years it will take her to get a graduate degree, so she decides to buy.

The total cost for five years when she rents.

→ 1350 + 795 × 12 × 5

→ $49,050

The total cost for five years when she buys.

→ 8235 + 750 × 12 × 5

→ $53,235

She made a poor decision if the property value does not increase. renting the townhome would be cheaper over the 5 years period.

Applying the law of cosines, the measure of angle Y in the image below, to the nearest whole degree, is: B. 64°

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)

-177 = -408(cos Y)

-177/-408 = cos Y

Y = cos^(-1)(177/408)

Y ≈ 64°

I'm guessing you want to find the value of D.

so,

-0.4 = 3d -10

3d = 9.6

d = 3.2

Answer: 3.2

Step-by-step explanation:

-0.4= 3d + (-10)

-0.4= 3d -10

add 10 to both sides

9.6 =3d

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.

Remark

2 angles are complementary means that 2 angles add up to 90°. That is the guiding princeple behind the problem.

Givens

Let the smallest angle = x

Let the largest angle = 4x + 30

Equation

4x + 30° + x = 90°                   Combine like terms on the left

Solution

5x + 30 = 90                            Subtract 30 from both sides.

5x + 30 - 30 = 90 - 30             Combine

5x = 60                                     Divide both sides by 5

5x/5 = 60/5

x = 12

Using the formula

sum of interiors=external

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°

Sum of interior angles of a polygon

180°(n−2)

When n=7,

Sum of interior angles of a polygon

180°(n−2)

=180°(7−2)

=900°

Therefore, Each interior angle of a regular heptagon measures 900/7=128.6°
