To find the percentage of roses in the garden, we first need to determine the total number of flowers in the garden. We can do this by adding the number of roses and lilies, and then multiplying that number by the ratio of roses to lilies. For example, if there are 3 roses and 2 lilies in the garden, the total number of flowers would be 5 (3 + 2 = 5). To determine the percentage of roses, we would then divide the number of roses by the total number of flowers, and multiply by 100. In this case, the percentage of roses would be 60% (3 / 5 * 100 = 60).

The statement that best describes how income levels have changed in the United States is given as follows:

C. High-income earners are making more, but most people have only seen limited gains.

Recently, in the entire world, an especially in the United States, inflation has been a problem, and thus people's income has not followed the pattern, staying mostly stagnant while inflation happens. This has happened even though the economy has improved from the 2008 global crisis.

However, high-income earners are making more, as the number of millionaires and billionaires increase, increasing the gap between high and low income earners. Thus option C is the correct option.

The true statement is option (A) The equation |-x - 4| = 8 will have two solution

Consider each statement

All the statements are absolute value equation

Part A

|-x-4| = 8

We can write it in two way

-x - 4 = 8

- x = 12

x = -12

Then,

-(-x-4) = 8

x+4 = 8

x = 4

It has two solution

Part B

3. 4|0. 5x - 42. 1| = -20. 6

Divide both side by 3.4

|0.5x - 42.1| = -103/17

Absolute value cannot be negative

The equation has no solution

Part C

|1/2x - 3/4| = 0

1/2x - 3/4 = 0

1/2x = 3/4

x = 3/4 ÷ 1/2

x = 3/2

The equation has one solution

Part D

|2x - 10| = -20

Absolute value cannot be negative

This equation has no solution

Part E

|0. 5x - 0. 75| 4. 6 = 0. 25

Divide both side by 4.6

|0.5x - 0.75| = 5/92

The equation divided into two

0.5x - 0.75 = 5/92

x = 37/23

0.5x - 0.75 = -5/92

x = 32/23

The equation has two solution

Part F

|1/8x - 1| = 5

1/8x - 1 = 5

x = 48

1/8x - 1 = -5

x = -32

The equation has two solution

Therefore, the equation |-x - 4| = 8 will have two solution is true

A prism having a triangular base is a right triangle of sides a and b = 2a.

The lengths of side "a" is 3.464 mm.

The length of side "b" is 6.928 mm.

Volume of the Triangular Prism:

A triangular prism is an object in three dimensional space with a triangular base and three other triangles connected to it. A triangular prism has four corners, and the distance from the base to the diagonal vertex is called the height of the triangular prism.

It is given by the multiplication of the area of the base to the height of the prism.

V = (Area × height of prism)/3

=> V = Ah/3

we have given that,

Base of prism is right angle triangle with sides "a" and "b" such that b = 2a ---(1)

Height of prism (h) = 10mm

Volume (V) = 40mm³

the Area of triangluar base = 1/2 × base× height of triangular base

A = (1/2)a ×b

=> A = (1/2)a × 2a = a²

Volume of prism (V) = a²×h/3 = 40

=> a²×10/3 = 40

=> a² = 120/10 = 12

=> a = √12 = 2√3

=> a = 2(1.732) = 3.464

from equation (1) , b = 2a = 2(3.464)

=> b = 6.928

So, the lengths of sides of triangle are

a= 3.464 and b = 6.928

Answer:

the price of an adult ticket is $8, and the price of a child ticket is $14.

Step-by-step explanation:

To find the price of an adult ticket and the price of a child ticket, we need to set up a system of equations. Let "A" represent the price of an adult ticket and "C" represent the price of a child ticket.

On the first day, the school sold 3 adult tickets and 1 child ticket for a total of $38, so we can set up the following equation to represent this information:

3A + C = 38

On the second day, the school took in $104 by selling 6 adult tickets and 4 child tickets, so we can set up the following equation to represent this information:

6A + 4C = 104

Now that we have our two equations, we can solve for the values of A and C. We can use the elimination method to solve this system of equations. To do this, we need to multiply one of the equations by a constant so that one of the variables has the same coefficient in both equations. We'll multiply the first equation by 2:

6A + 2C = 76

We can then subtract this equation from the second equation to eliminate the C term:

6A + 4C - 6A - 2C = 104 - 76

This simplifies to:

0A + 2C = 28

Dividing both sides by 2, we get:

C = 14

We can now substitute this value for C in one of our original equations and solve for A. We'll use the first equation:

3A + 14 = 38

Subtracting 14 from both sides, we get:

3A = 24

Dividing both sides by 3, we get:

A = 8

Therefore, the price of an adult ticket is $8, and the price of a child ticket is $14.

The level in the pot rising when the coffee in the cone is 5 in deep is 0.35 in/min.

Here the variables are the height of the coffee in the filter hf , the radius of the top of the coffee in the filter rf , and the height of the coffee in the pot hp:

We allowed Vp to represent the volume of coffee in the pot. We are interested in the instant when

hf = 5 in and dVp/dt = 10 in³/min.

The question is dhp/dt =? when dVp/dt = 10 in³/min and hf = 5 in

We need to relate hp to the other variables. In the pot (idealized as a cylinder), we have the volume Vp as Vp = π(3)²hp = 9πhp in³(since the volume of a cylinder of radius r and height h is V = πr²h).

Differentiation of Vp with respect to time gives dVp/dt = 9πhp/dt or

dhp/dt = (1/9π).(dVp/dt)

When dVp/dt = 10 in³/min and hf = 5 in, we have

dhp/ dt = 1/9π(10)

= 10/9π in/min

dhp/ dt ≈ 0.35 in/min (notice that the answer here is independent of hf ).

Hence, the level in the pot rising when the coffee in the cone is 5 in deep is 0.35 in/min.

False. All economists do not believe that predatory pricing is a profitable business strategy.

What does "predatory pricing" mean?

A dominant company will often use predatory pricing as a deliberate strategy to drive out rivals by setting exceptionally cheap prices or supplying products for less than the company would otherwise have to spend on manufacturing (often equated for practical purposes with average variable costs).

Predatory pricing, sometimes referred to as undercutting, is a pricing strategy in which a good or service is offered at an extremely low cost with the goal of driving out rivals or establishing barriers to entry for potential new competitors.

If a competitor was selling a TV for $100 and you were offering the same TV for $80, you would be using predatory pricing.

The dependent variable in this hypothesis is test performance.

What is a dependent variable?

In mathematical modelling, statistical modelling, and experimental sciences, there are dependent and independent variables. Dependent variables get their name because, during an experiment, one‘s values are examined under the assumption as well as demand that they are dependent on the value of another variable due to some law or rule (for example, a mathematical function). In the context of the experiment in question, independent variables are those that are not thought to be depending on other variables. Time, space, specific gravity, mass, fluid flow rate and previous values of certain observed value of interest (such as the size of the human population) are examples of common independent variables that can be used to forecast future value systems (the dependent variable).

The outcome of this hypothesis is the dependent variable.

The range of the function f(x) = 5 -10x for domain {-1, 2, 4}  is { 15, -15, -35}

A function's domain and range are its constituent parts. Range, Domain, and Function. A is the domain and B is the co-domain if a function f: A B exists that maps every element of A to an element in B. 'b', where (a,b) R, provides the representation of an element 'a' under a relation R. The collection of photos is the function's range. In general, a function's domain and range are denoted as follows:

Domain(f) = {x ∈ R} and range(f)={f(x) : x ∈ domain(f)}

"All the values" that are input into a function are referred to as the domain of a function. The collection of all potential inputs for a function is its domain. Think of this box as the f(x) = 2x function. The domain is only the collection of natural numbers when the input values are x = 1,2,3,4,..., and the values that are returned are referred to as the range. However, f(x) = 2x is often defined for all real values of x, and as a result, its domain is the set of all real numbers, which is represented by  (-∞, ∞). The general formulae for determining the domain of various types of functions are listed below. The set of all real numbers, or R, is used here.

The collection of all a function's outputs is its range. Example: Let's have a look at the function f: A->B, where f(x) = 2x and A and B each represent a "collection of natural numbers." The domain in this instance is A, and the co-domain is B. The range then appears as the function's output. Set of even natural numbers is the range. The components of the co-domain that are mapped are known as the pictures, while the elements of the domain are known as pre-images. The set of all pictures of the domain's elements in this case serves as the function's range, as does the set of all of its outputs.

Domain of the function x = {-1,2,4}
