On solving the equation, it is seen that about 12 ounces of the 15% solution must be mixed with about 6 ounces of the 6% solution to get 18 ounces of the 12% perfume.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

Let x = number of liters of the 15% solution

Let 18 − x = number of liters of the 6% solution

Solution Ounces Strength Amount of Perfume

15%         x            15            15x

6%          18 - x      6             6(18 - x)

Mixture   18           12            (18)(12)

So, the equation will be -

(amount of perfume in 15% solution) + (amount of perfume in 6% solution) = (amount of perfume in mixture)

15x + 6(18 − x) = (18)(12)

Solve the equation using distributive property -

15x + 108 - 6x = 216

Combine the like terms -

15x - 6x = 216 - 108

Simplify the equation further -

9x = 108

x = 108/9

x = 12

Now, substituting the value of x in 18 − x = 18 - 12 = 6.

Therefore, the amount in ounces is obtained as 12 ounces and 6 ounces.

The number of quarters in the bowl is 14.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x+ 3 = 9 is an equation.

We have,

Dimes = x

Quarters = y

10 dimes = $1

1 dime = $0.1

4 quarters = $1

1 quarter = $0.25

Now,

0.1x + 0.25y = 5 _____(1)

x + y = 29 _____(2)

Solve for y from (1) and (2),

x = 29 - y

Substitute in (1) we get,

0.1 (29 - y) + 0.25y = 5

2.9 - 0.1y + 0.25y = 5

2.9 + 0.15y = 5

0.15y = 5 - 2.9

y = 2.1/0.15

y = 14

Thus,

There are 14 quarters in the bowl.

The ODE's general solution has real solution and complex eigen functions. Typical trajectories are sinusoidal curves.

The general solution of the ODE involves complex eigenfunctions, which are solutions of the form e^(ikx), where k is a real number and i is the imaginary unit. By combining these complex eigenfunctions with real coefficients, a general real solution can be obtained. Typically, these solutions will take the form of sinusoidal curves, with the amplitude and period determined by the coefficients of the eigenfunctions. The coefficients can be determined using initial conditions, allowing for more specific trajectories to be determined. For example, if the initial condition is known, then the coefficients of the eigenfunctions can be determined using Fourier analysis, allowing for the trajectory of the system to be determined.

the two possible values for the third side of the triangle are 22.5 and 24.00.

We know that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Therefore, the third side must be greater than 10.25 and less than 19.75.

From this, we can conclude that the third side of the triangle must be either 22.5 or 24.00.

We know that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Given that two sides of the triangle measure 19.75 and 10.25, the third side must be greater than 10.25 and less than 19.75. Therefore, the only two possible lengths for the third side of the triangle are 22.5 and 24.00. Any length greater than 19.75 or less than 10.25 would not satisfy the triangle inequality and would not be a valid third side for the triangle. Thus, We know that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

The required values are for the given angle, as follows: a. sin α is positive. b. sin(π + α) = -sin α. c. cos(2π - α) = cos α.

A quadrant is defined as an area contained by the x and y axes, which there are four quadrants in a graph.

a. For an angle α in the first quadrant, sin α is positive.

Since the first quadrant is between 0 and 90 degrees, sin α is equal to the opposite side divided by the hypotenuse, where the opposite side is the y-coordinate and the hypotenuse is the distance from the origin to the point on the unit circle corresponding to the angle α.

b. sin(π + α) = sin (π - α). In the second quadrant (90 < α < 180), sine is negative, so sin(π + α) = -sin α.

c. cos(2π - α) = cos α. The cosine function has period 2π, so cos(2π - α) = cos α.

Since the first quadrant is between 0 and 90 degrees, cos α is positive.

To find out how many bricks are needed to make the wall, we need to find the total area of the wall and divide it by the area of one brick.

The area of the wall is:

length x height x width = 10 m x 1 m x 0.5 m = 5 m^2

The area of one brick is:

10 cm x 10 cm x 20 cm = 2000 cm^3

To convert the area of the wall from square meter to cubic centimeter, we need to multiply it by 100*100 = 10000.

5 m^2 x 10000 = 50000 cm^2

Now we can divide the total area of the wall by the area of one brick to find out how many bricks are needed:

50000 cm^2 / 2000 cm^2/ brick = 25 bricks

So, 25 bricks will be needed to make the wall.

The equation for the parabola is: (x - 1)^2 = 4(y - 5). This equation describes a parabola with its vertex located at (1, 5) and its focus at (1, 1). The parabola is symmetrical about the y-axis and opens upward. This means that the base of the bulb is at (1, 5) and the top of the bulb is at (1, 1). To get the equation for the parabola, we need to subtract the x-coordinate of the vertex from the x-coordinate of the focus, which gives us 1. We then square this number, giving us 1. We then subtract the y-coordinate of the vertex from the y-coordinate of the focus, giving us 4. We then multiply this number by the squared number from before, giving us 4.

Step-by-step explanation:

red line length call it a² = (8√3)²- 12²  = 192-144 =48

so look at the graph we know x is longer than 12,

the portion that's longer than 12 call it c = x-12

top short line call it b

because it's all right angle you are looking at 3 right angle triangles

the big one that's cut into 2 by the red line

the larger one & the smaller one

each will have this property: short side 1 ²+short side 2 ²= long side ²

so for the largest one:

(8√3)² +b² = (12+c)² = x²

second largest triangle we already know all 3 sides: (8√3), 12, √48

now look at the smallest

48+c² =b²

X = 88.1. The total of all interest, dividends, or other income that an investment provides divided by the age of the investment or the period over which the investor has held it is the average yield on an investment.

What is average yield?

The average yield on an investment or a portfolio is calculated by dividing the total interest, dividends, or other income received by an investment by the investment's age or the period over which the investor has held it. In particular, it alludes to yield, or the total revenue from an investment divided by the number of years kept.

There are numerous yield kinds, and the calculating process varies depending on the specific yield type and the type of security. Because of these variations, comparisons of yields between other financial product categories should be used with caution.

In the case of stocks, yield is determined by dividing the price rise plus dividends by the original purchase price. Both cost yield and current yield can be used to examine bond yield.

b. (10, 20, 30) will not create a triangle

c. (15.5, 45, 20.5) will not create a triangle.

What is a triangle?

A triangle is a polygon with three sides and three angles. The sum of the interior angles of a triangle is always 180 degrees. Triangles can be classified by their sides (such as equilateral, isosceles, or scalene) or by their angles (such as acute, right, or obtuse).

The set of lengths (3,4,5) will create a triangle. This is because it follows the "triangle inequality theorem" which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

The set of lengths (10, 20, 30) will not create a triangle. This is because 10 + 20 is less than 30, so it does not satisfy the triangle inequality theorem.

The set of lengths (15.5, 45, 20.5) will not create a triangle. This is because 15.5 + 20.5 is less than 45, so it does not satisfy the triangle inequality theorem.

The measure of the missing angle in a triangle is C = 18°.

An acute angle is one that is 45 degrees. It is a 90-degree angle or half of a right angle. Look at the illustration of the 45-degree angle. Angles are expressed in degrees or radians.

A straight angle is one in which the two arms extend in precise opposition to one another. A 180° angle is a straight angle. A protractor can be used to measure angles; a straight angle is an angle that is measured at 90 degrees.

The two arms are perpendicular to one another at a right angle. Each angle measures 45° when the right angle is divided into two equal pieces. An acute angle is one that is 45 degrees. It is a 90-degree angle or half of a right angle.

Given one of the angles A = 45°

And B is 65% of the total angle sum = 65/100 × 180

                                                             = 117°

For angle C, using angle sum property

⇒ A + B + C = 180°

⇒ 45° + 117° + C = 180°

⇒ C = 180° - (45° + 117°)

⇒ C = 180° - 162°

⇒ C = 18°

Thus, The measure of the missing angle in a triangle is C = 18°.
