Two angels whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

Given;

(x+14), (9x-4)

Now,

According to supplementary angles;

(x+14)+ (9x-4)=180

10x+18=180

We are aware that x+y=15 (the total number of mugs he buys).The man then purchased 5 large cups and 10 mini mugs .

Let x represent how many little cups he buys.

Let y represent how many large mugs he purchases.

We are aware that x+y=15 (the total number of mugs he buys)

We are also aware of the mugs' costs.

The total price (69) can therefore be deduced to equal 3.50x + 6.80y.

To find x, use the first equation.

x = 15 - y

You can now enter that x-value into the other equation.

69 = 3.50(15 - y ) + 6.80y

Solve for y now.

69 = 52.5 -3.50y + 6.80y

69= 52.5 + 3.3y

Answer:

12.5%

Step-by-step explanation:

12.5% of 120 is 15 so if you take 15 divided by 120 you would get 0.125 and turned into a percentage is the 12.5%

2x(6x2 + 4x − 3) × (2x − 3)(5x + 6)

= (2x)2(6x2 + 4x − 3)(5x + 6)

= 12x3(5x + 6) + 8x2(5x + 6) − 6x(5x + 6)

= 60x4 + 48x3 − 45x2 − 36x

If the area of the triangle is 120 cm^2, the value of x is equal to 6.

Mathematically, the area of a triangle can be calculated by using this mathematical expression:

Area of a triangle (A) = 1/2 × b × h

Where:

According to Hero's Formula area of triangle by Heron of Alexandria, if a, b, c are the side lengths of a triangle, then, the area of a triangle can be calculated by using this mathematical expression:

Area of a triangle (A) = √[s(s − a)(s − b)(s − c)]

Where:

s = (a + b + c)/2

s = (x + x + 1 + 2x - 1)/2

s = 4x/2

s = 2x

Substituting the parameters into Hero's Formula formula, we have the following;

x√10 = √[2x(2x − x)(2x − x - 1)(2x − 2x + 1)]

x√10 = x√2(x − 1)

√10 = √2(x − 1)

Taking the square of both sides, we have:

10 = 2(x - 1)

10 = 2x - 2

2x = 12

x = 12/2

x = 6.

The basic formula for the area of a triangle is (1/2) × base × altitude. But we have to calculate the area of a triangle in coordinate geometry. Coordinate geometry is defined as the study of geometry using coordinate points. If coordinates of the triangle are(x₁, y₁), (x₂, y₂), and (x₃, y₃) then the area of the triangle is defined as Area = 1/2[ x₁(y₂ - y₃) + x₂( y₃ - y₁) + x₃(y₁ - y₂) ]

To solve the equation 2x + 3y = 10 we need to plot the graph for the equation by calculating the intercepts for the same.

Here we see that we are given the equation

2x + 3y = 10

Since we do not have any other equation we will solve this by plotting it on a graph by the intercepts.

Intercepts of both the x and y axes are obtained by equating the other to 0.

Hence to get the x-intercept, we need to equate y to 0

Hence we get

2x = 10

or, x = 5

Hence for the y-intercept, we equate x to 0 to get

3y = 10

or, y = 10/3

By plotting these points and drawing a line through them we will get the graph for the equation.

Now to obtain a unique solution, we need to follow similar steps for the other equation and the intersecting point will give us the solution.

A circle not 100 degrees because 360 is a highly composite number, when a circle is drawn it completes a whole loop making it a 360 degrees.

As you presumably well know, we can measure angles in other ways other in degrees. Angles are also measured in radians and, on a very rare occasion, in the enigmatic gradians used by the military (thus the presence of "deg rad grad" buttons on many calculators).

While the reason the 360 degree convention was chosen is unknown to us, we do know roughly when and where it all began (more on that in a moment).

Answer:

To find the amount of money after 10 years, we can use the formula for compound interest: A = P(1 + r/n)^(nt)

Where:

A = the amount of money after 10 years

P = the initial investment (24000 birr)

r = the interest rate (4%)

n = the number of times the interest is compounded per year

t = the number of years

In this case, since the interest is compounded annually, n = 1.

So,

A = 24000(1 + 0.04)^(1*10)

A = 24000(1.04)^10

A = 24000(1.46) = 24000*1.46 =35,040 birr

So, after 10 years the total amount of money will be 35,040 birr.

What is rectangle ?

A rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle.

To find the rectangular coordinates for a point in a plane given its polar coordinates, use the following formula:

x = r * cos(θ)

y = r * sin(θ)

Where (r, θ) are the polar coordinates and (x, y) are the rectangular coordinates.

For the point (4.5, -30 degrees), have:

r = 4.5

θ = -30 degrees = -30 * (π / 180) radians

x = r * cos(θ) = 4.5 * cos(-30 * (π / 180)) = 3.9

y = r * sin(θ) = 4.5 * sin(-30 * (π / 180)) = -2.3

The rectangular coordinates for (4. 5, -30 degrees) are (3.9, -2.3).

The rectangular coordinates for (4.5, -30 degrees) can be found using the following formula:

x = r * cos(θ)

y = r * sin(θ)

where r is the magnitude (or distance from the origin) and θ is the angle in radians.

In this case, r = 4.5 and θ = -30 degrees = -30 * (π/180) radians.

So:

x = 4.5 * cos(-30 * (π/180)) = 4.5 * cos(-π/6) = 4.5 * sqrt(3)/2

y = 4.5 * sin(-30 * (π/180)) = 4.5 * sin(-π/6) = -4.5 / 2

Therefore, the rectangular coordinates are (x, y) = (4.5 * sqrt(3)/2, -4.5 / 2), which is approximately (3.9, -2.3).

Option B (3.9, -2.3) is the right response as a result.
