Answer:

Same side exterior anglesx = 15

Step-by-step explanation:

The indicated angles are same side exterior angles since located on the same side of the transversal and exterior to parallel lines.

Same side exterior angles are supplementary, so their sum is 180.

Solve the following equation for x

7x + 3 + 4x + 12 = 18011x + 15 = 18011x = 165x = 165/11x = 15

Angles are supplementary as they are same side exterior angles

7x+3+4x+12=18011x+15=18011x=165x=15

A function that represents the number of minutes it takes to deliver x newspapers is y = 12 + 2x/3.

What is the function?

The function that represents the number of minutes it takes to deliver x newspapers is: total minutes = time it takes to orgainse the newspapers + time it takes to deliver x newspapers

Time it takes to orgainse the newspapers = 12 minutes

The area of a square is the square of the side length. When the side length x=2.5 cm, the area is the square of that value.

__

  A(x) = x²

  A(2.5 cm) = (2.5 cm)² = 6.25 cm²
_____

Additional comment

The "square" of a variable is that variable to the second power. The terms 2x or 4x are linear terms with the variable to the first power, do not represent the area of a square.

The equation A(x) = 4x² introduces a multiplier of 4 that is not applicable to the area of a square based on side length. (The formula might be useful if x represents the distance from one side to the center of the square, the radius of an inscribed circle, for example.)

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

Answers

Answer:

Step-by-step explanation:

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

Answer

smallest angle = 12Larger angle = 4*12 + 30 = 78

What is the measure of angley to the nearest whole degree? 58° 64° 68° 73°

Answers

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)

-177 = -408(cos Y)

-177/-408 = cos Y

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

Y ≈ 64°

Answers

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.

Step-by-step explanation:

the circumference of a circle is

with r being the radius.

in our case

9×pi = 2×pi×r

r = 9/2 = 4.5 cm

What is the equation of the line that passes through the point (1, 3) and is perpendicular to the line 2x + 3y = 15?

Answers

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

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

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.

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

The sections of a spinner are divided into five
equal sections and are lettered A to E. Myla spins
the pointer of the spinner once and rolls a number
cube numbered 1 to 6. What is the probability of
landing on B and rolling an even number?

Answers

Answer: 0.066, or a 6.6% Statistical Probability.

Step-by-step explanation:

When dealing with Statistical Probability, you are attempting to find the theoretical chance of an action occuring.

With the two actions described, one being a wheel with five set outcomes, and a dice with six set outcomes, you can find the probability of random numbers/outcomes by taking

[tex]\frac{1}{6} \\and\\\frac{1}{5}[/tex]

1/6 being number cube, 1-2-3-4-5-6

and

1/5 being spinner. A-B-C-D-E

In the Event, (made up by actions), it is described that The Cube AND Spinner are rolled and spun at random.

Also, The description asks: what is the probability of landing on B and rolling an even number?

So, the 1/6 chance of the dice becomes 1/3, or .33 or 33%.

And, the 1/5 chance for the spinner stays the same, because it is a single unit. So, probability of landing on B is still 1/5, or .2 or 20%.

When two actions are present in an Event, you are to procedurally multiply the outcomes by the decimal percentage, fraction, or actual percentage, to find the chance of occurence.

In this scenario, I used .2 x .33 and got 0.066

Which, equals 6.6%

I found this by multiplying the decimal percentage by 100, to scale the chance on a 100/100 based scale. In this case, the multiplier on the numerator is .066 ... creating 6.6/100, or .066 or 6.6%
