Step-by-step explanation:

13 diamonds, y = 3 chandeliers, x = 52 diamonds, x = 130 diamonds, y = 40 chandeliers. this is the complete table using equivalent ratios.

When we compare any two kinds of ratios, they are said to be equivalent. To determine whether these two or more ratios are equivalent, they can also be compared to one another. For instance, the ratios 1:2 and 2:4 can be called as equivalent.

Simply put, a ratio is a comparison of two numbers. When a ratio is equal, the proportionate relationship remains constant. By multiplying the first value by the same ratio, or unit of proportion, you can determine your own equivalent ratios.

It is possible to treat an equivalent ratio and a proportion interchangeably. An equivalent ratio is the result of simplifying the two ratios to the same fraction.

Let us take the value of x -----> the number of diamonds

Let us take the value of y ----> the number of chandeliers

we know that

The ratio present between the number of diamonds to that of the number of chandeliers is equal to

[tex]\frac{x}{y} = \frac{39}{3}[/tex]

1) for y = 1,

x = 13 diamonds

2) for x = 39

y = 3 chandeliers

3) for y = 4

x = 52 diamonds

4) y = 10

x = 130 diamonds

5) x = 520

y = 40 chandeliers

Answer:

9, 4/4, and 1.00000

Explanation:

Whole numbers are the basic counting numbers 0,1,2,3,4,...There is no fractional or decimal part. And no negatives.

Given the numbers:

• Firstly, 9 is clearly a whole number

• 4/4 = 1. 4/4 is a fraction that is equivalent to a whole number. Therefore, it is a whole number.

• 1.00000=1. Whenever there is a decimal in which all the digits after the decimal point are zeros, the number is a whole number.

The transformation that took f(x) = 3x+1 to g(x) = −3x−5 is reflection and translation 4 units downwards

given data

f(x) = 3x+1

g(x) = −3x−5

Reflection

Reflections changes the sign of the both coordinates

from                                      to

f(x) = 3x + 1                          f'(x) = -3x - 1

Translation

Translation downwards leads to subtraction with the required units in the y coordinates. In this case 4 units

from                                     to

f'(x) = -3x - 1                          f''(x) = -3x - 5

Answer:

Either of ...

Step-by-step explanation:

You want the transformations that take f(x) = 3x+1 to g(x) = -3x-5.

The x-term of the transformed function has a sign opposite that of the original function. That can be accomplished by either of (a) reflection across the y-axis (replaces x by -x), or by (b) reflection across the x-axis (replaces f(x) by -f(x)).

Either way, an additional translation is required. That translation can be either vertical or horizontal, and may be done either before or after the reflection.

Reflecting f(x) across the y-axis means it becomes ...

  f(-x) = 3(-x) +1 = -3x +1

In order to make that into -3x-5, we must add -6 to the function value:

  g(x) = f(-x) -6 = (3(-x)+1) -6 = -3x -5

F(x) will be taken to g(x) = -3x-5 by reflection across the y-axis and translation down 6 units.

Reflecting f(x) across the x-axis means it becomes ...

  -f(x) = -(3x +1) = -3x -1

In order to make that into -3x-5, we must add -4 to the function value:

  g(x) = -f(x) -4 = -(3x +1) -4 = -3x -5

F(x) will be taken to g(x) = -3x-5 by reflection across the x-axis and translation down 4 units.

__

Additional comment

As noted above, the translation can be either horizontal or vertical. For example, translating the function 2 units to the right makes it f(x-2). Then reflection across the y-axis replaces x by -x, so we have ...

  g(x) = f(-x-2) = 3(-x-2)+1 = -3x -6 +1 = -3x -5

To get g(x), we could translate right 2 units, then reflect across the y-axis.

We also note that point (-1, -2) is shared by f(x) and g(x), so reflection horizontally across the line x=-1, or vertically across the line y=-2 would also give the required transformation.

They have an 89% satisfaction rate, less than the goal.

Step-by-step explanation:

To find this, divide 1068/1200, this gives you 0.89

This shows that they have an 89% satisfaction rate.

Since, the satisfaction rate 89% which is less than 90%. Therefore, management will take corrective actions.

Given that, if the retailer wants to stay competitive, then it will have to have at least a 90% satisfaction rate among its customers.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

A survey of 1,200 customers showed that 1,068 were satisfied with their customer service.

Here, the satisfaction rate = 1068/1200 ×100

= 0.89 ×100

= 89%

Since, the satisfaction rate 89% which is less than 90%. Therefore, management will take corrective actions.

Explanation

To determine the probability that the number rolled is odd using a standard die, we first list the total outcomes as shown below:

1,2,3,4,5,6

As we can see, the odd numbers are:

1,3,5

This means that the total favorable outcomes is 3.

Now, we use the formula:

We plug in what we know:

Therefore, the probability that the number rolled is odd is 1/2.

Answer:

3/6

A standard die has 6 sides, numbered 1 through 6 (1,2,3,4,5,6). That means we have 3 odd numbers (1,3,5)  and 3 even numbers (2,4,6).

The total possible outcomes of an odd number are 3, because there are 3 odd numbers, and the total outcomes are 6. So we write it as 3/6, like 3 out of six chances of getting an odd number.

It can be simplified to 1/2.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves.

Angle can also refer to the length of a rotation or an angle. This metric represents the relationship between a circular arc's length and radius. The arc is centered at the vertex and defined by the sides in the case of a geometric angle. When there is a rotation, the arc is defined by any other point and the rotation's image, and it is centered at the rotation's center.

Inequality, a declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.

a = number of hours spent tutoring

y = number of hours spent landscaping

Micaela can't work more than 13 hours, so a + y ≤ 13.

Also, she needs to earn at least $140 each week, so 13a + 10y ≥ 140.

Using intercepts, you may graph things in this format on paper. They must be transformed into slope-intercept form in order to be graphed on a standard graphing calculator.

By applying the elimination method the value of x is - 2 and y is 7.

This is a problem from algebraic equations and we have to apply the elimination method. We can solve this problem by following a few steps.

So, the given equation according to the question is,

− 2x = 4 ................ ( equation 1 )

4x + 2y = 6 ............... ( equation 2 )

While applying the elimination method we have to multiply equation (1) with the positive coefficient of x in the second equation and vice versa.

Here the coefficient of x in the first equation is 2 and in the second equation is 4.

Now, we have to multiply equation ( 1 ) with 4 and equation ( 2 ) with 2.

Therefore,

− 2x = 4 ................ ( equation 1 ) × 4

4x + 2y = 6 ............... ( equation 2 ) × 2

Now, we can rewrite the equations as,

− 8x = 16 .................. ( equation 3 )

8x + 4y = 12 .................. ( equation 4 )

Now the coefficient of x in both equations are same but opposite sign. So, we have to add the equations.

Here we get , -8x + 8x + 4y = 16 + 12

Or, 4y = 28

Or, y = 7

Now, we have to put the value of y in any equation.

4x + 2.7 = 6  ( equation 2 )

Or, 4x = 6 - 14 = -8
