65 ÷ 10 = 6.5

Divide 65 by 10 to figure out how many words he can text in one minute, which is 6.5.

143 ÷ 6.5 = 22

Divide 143 by 6.5 to get the amount of minutes it takes, which is 22.

The price of the stereo system after the markup was $691.20.

The original price of the stereo system was $720.

During the sale, the price was reduced by 20%, which is equivalent to multiplying by (1 - 0.2) = 0.8.

The discounted price was:

720 × 0.8 = $576

After the sale, the discounted price was marked up by 20%

It is equivalent to multiplying by (1 + 0.2) = 1.2.

So the final price was 576 × 1.2

= $691.20

Therefore, the price of the stereo system after the markup was $691.20.

The value of the middle of the three is 25.

Let x be the first odd integer, then the next two consecutive odd integers are x+2 and x+4. The sum of these three consecutive odd integers is given as 75, so we can write the equation:

x + (x+2) + (x+4) = 75

Simplifying the left side of this equation gives:

3x + 6 = 75

Subtracting 6 from both sides gives:

3x = 69

Dividing by 3 gives:

x = 23

So the first odd integer is 23, and the next two consecutive odd integers are 25 and 27. The middle of these three is the second consecutive odd integer, which is 25. Therefore, the value of the middle of the three is 25.

Answer:

48 ft

Step-by-step explanation:

Here, we want to find the length of the wire

from the diagram, we can identify two similar triangles

The smaller one and a bigger one

Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal

We can start by getting the height of the tower

we have this as:

8/11 = 28/x

8 * x = 28 * 11

8x = 308

x = 308/8

x = 38.5 ft

So as we can see, the wire represents the hypotenuse of the larger triangle that measures 28 ft base and 38.5 ft height

So we can use the Pythagoras’ theorem to get the hypotenuse

Let us call this g

mathematically according to the theorem, the square of the hypotenuse equals the sum of the squares of the two other sides

thus, we have it that;

g^2 = 38.5^2 + 28^2

g^2 = 2,266.25

g = √2,266.25

g = 47.61 which is approximately 48 ft

The statement "reducing the payment of rent to land owners will decrease the quantity of land supplied" is true.

When the payment of rent to landowners is decreased, it will lead to a decrease in the quantity of land supplied.

What is the meaning of the law of supply?

The law of supply is a fundamental principle of economic theory that states that as the price of a good or service increases, the quantity supplied of that good or service increases, ceteris paribus. Ceteris paribus is a Latin term that means "all other things being equal." The law of supply is one of the most basic principles of economics and is essential for understanding how markets function.

What is the relationship between rent and land supplied?

In the context of the law of supply, the relationship between rent and land supplied is that the supply of land is determined by the price of rent. When the payment of rent to landowners is decreased, it will lead to a decrease in the quantity of land supplied. This is because landowners will be less willing to supply land at a lower rent.

The converse is also true. If the payment of rent to landowners is increased, it will lead to an increase in the quantity of land supplied. This is because landowners will be more willing to supply land at a higher rent. Therefore, the price of rent is an important factor in determining the supply of land. If the price of rent is too high, landowners may choose not to supply land, which can lead to a shortage of land.

In spherical coordinates, the equation \(5z^2 = 6x^2 + 6y^2\) can be written as: \(ρ^2sin^2(φ) = 6ρ^2sin^2(θ)cos^2(φ) + 6ρ^2sin^2(θ)sin^2(φ)\)

Spherical coordinates are a system of coordinates used to represent points in three-dimensional space. In this coordinate system, a point is described by three parameters: ρ (rho), θ (theta), and φ (phi).

ρ (rho) represents the radial distance from the origin to the point.

θ (theta) represents the azimuthal angle, which is the angle measured in the xy-plane from the positive x-axis to the line connecting the origin and the point.

φ (phi) represents the polar angle, which is the angle measured from the positive z-axis to the line connecting the origin and the point.

In spherical coordinates, a point in 3D space is represented using three parameters: ρ (rho), θ (theta), and φ (phi).

ρ (rho) represents the radial distance from the origin to the point.

θ (theta) represents the azimuthal angle, which is the angle measured in the xy-plane from the positive x-axis to the line connecting the origin and the point.

φ (phi) represents the polar angle, which is the angle measured from the positive z-axis to the line connecting the origin and the point.

To express the equation\(5z^2 = 6x^2 + 6y^2\)in spherical coordinates, we need to convert the variables x, y, and z to their corresponding spherical coordinate representations.

In spherical coordinates, the conversions are as follows:

x = ρsin(φ)cos(θ)

y = ρsin(φ)sin(θ)

z = ρcos(φ)

Substituting these values into the equation, we have:

5(ρcos(φ))^2 = 6(ρsin(φ)cos(θ))^2 + 6(ρsin(φ)sin(θ))^2

Simplifying the equation further by expanding the terms and using trigonometric identities, we can obtain the equation in spherical coordinates:

\(ρ^2sin^2(φ) = 6ρ^2sin^2(θ)cos^2(φ) + 6ρ^2sin^2(θ)sin^2(φ)\)

This equation relates the variables ρ, θ, and φ in spherical coordinates and represents the same relationship as the original equation in Cartesian coordinates.

Answer:

x = 25 degrees

Step-by-step explanation:

the angle for a straight line is 180, so add 125 and 30 together, which gets 155. then subtract 155 from 180 which gets 25 degrees as x

This is true because coordinates (0.8, 0.6) satisfy the equation x² + y² = 1.

The approximate angle measures needed to intersect at (0.8, 0.6) and each of these new points is 38.66 degrees.

Other points on the unit circle are (0.6, 0.8), (-0.8, 0.6), (-0.6, -0.8), and (0.8, -0.6).

The coordinates (0.8, 0.6) lie exactly on the unit circle because they satisfy the equation x² + y² = 1, which defines the unit circle. Plugging in x = 0.8 and y = 0.6 gives 0.8² + 0.6² = 1, which is true.

To find the angle measure needed to intersect at (0.8, 0.6) and each of the new points, we can use the inverse tangent function. If we let theta be the angle between the positive x-axis and the line connecting the origin and the point of intersection, then we can use the equation tan(theta) = y/x to find the angle. For example, to find the angle needed to intersect at (0.8, 0.6) and (1, 1), we have tan(theta) = 0.6/0.8, which simplifies to theta = arctan(0.6/0.8) ≈ 38.66 degrees.

The other points on the unit circle that also lie exactly at the intersection of two grid lines are (0.6, 0.8), (-0.8, 0.6), (-0.6, -0.8), and (0.8, -0.6). These points can be obtained by reflecting (0.8, 0.6) across the x-axis, y-axis, or both.
