Use 4 of the 5 numbers shown to make the equations true.

Each number can be used only once.

Addition is commutative because the order in which two numbers are added does not affect the result.

Commutative property is applicable only for addition and multiplication processes. Thus, it means we can change the position or swap the numbers when adding or multiplying any two numbers.

Addition is commutative because the order in which two numbers are added does not affect the result. For example, 1 + 2 = 2 + 1 = 3. In contrast, subtraction is not commutative because the order in which two numbers are subtracted does affect the result. For example, 1 - 2 = -1, but 2 - 1 = 1. The operation is different when the order of the numbers are changed.

so, addition is commutative because the order in which two numbers are added does not affect the result.

The angle of incline, of the target θ = 14.036.

The angle of elevation or depression can be calculated using the following formula: t a n = O A, where A is the horizontal distance between the observer and the point and O is the length of the side opposite the angle of elevation or depression, or the object's perpendicular distance from the horizontal line.

To calculate the slope percentage, multiply the result by 100 after dividing the height difference between two points by their separation. The rise is the height difference between two locations. The distance between the locations is known as the run. The result is that (rise / run) x 100 is equal to the percent slope.

Given,

the height of triangle = 12in

base of triangle = 48 in

tan θ = perpendicular / base

tanθ = 12/48

θ = tan ⁻¹( 12/48)

θ = 14.036

Complete question -

Mariela spends $50 on a used microwave. By 60%, she raises the price. When a 5.8% sales tax is additionally included, the ultimate cost is 20 in 60% and 47.1 in 5.8%.

Cost plus markup % multiplied by cost is the formula used to increase a product's markup percentage. Let's say you're utilising a markup of 60% and the item costs $75. multiplying by 60 percent $75. Now you have $45. For instance, the markup percentage would be 50% if the cost to produce your product was $50 and the selling price was                      $75: ($75 - $50) / $50 =.50 × 100=50%.

0.6 is 60 hundredths of a unit, thus write it as 0.60. 60% is equal to 60 hundredths. The decimal point can alternatively be shifted two places to the right to find the % equivalent. As a result, the markup equation is now: markup = 100 × (revenue - cost) / cost. Last but not least, use revenue = cost + cost × markup / 100 to determine the selling price.

It depends on the specific nonlinear system of equations. Generally speaking, there could be one or multiple solutions, or there could be no solutions.

A nonlinear system is a system of equations or functions which does not yield a linear relationship or linear solution when solved. A nonlinear system is often difficult to solve due to its inherently complex nature. Nonlinear systems can be found in multiple areas, such as engineering, economics, and mathematics.

If the equations are linear, then there will be exactly one solution. If the equations are nonlinear, then there could be no solutions, one solution, or multiple solutions (including infinitely many solutions). To find the exact number of solutions, you would need to solve the system of equations.

The length of BC is 5.7 cm

A dot is used to symbolise a point, which is a place in any space (.). It does not have any size, shape, length, or height. A line segment has a beginning and an end, but a line is stretched in both directions towards infinity.

It is given that the length of AB is 8.6 cm and length of AD is 20 cm.

Also, BC=CD

As there are 4 points (A, B, C, D) on the line and the length of the lone is 20 cm, we     can say

AB+BC+CD= 20 --------------- (1)

Let us consider that BC=CD= x (say)

Substituting the values in equation (1),

8.6+ x+ x=20

Or, 2x =11.4

Or, x=11.4/2

Or, x=5.7 cm

In order to prove that ∠MPQ is congruent to ∠MLN, she requires that PQ and LN should be parallel.

What are parallel lines?

When two lines in a plane do not cross at any point, they are said to be parallel. Lines that never cross paths with one another and do not have a common junction point are said to be parallel. They are equally spaced apart and have the same incline.

We know that corresponding angles of parallel lines are equal.

As shown in the figure, ∠MPQ and ∠MLN are corresponding angles.

To find out how many pages Van fills with his new baseball cards, we need to divide the total number of cards by the number of cards that fit on each page.

He has 45 baseball cards and each page holds 9 cards.

So, we can divide 45 by 9.

45 / 9 = 5

Therefore, Van fills 5 pages with his new baseball cards.

It's worth noting that this method gives the number of full pages that are filled and if there are any remaining cards, we have to add one more page for the remaining cards.

The equation for g(x) would be g(x) = 9cos(x-1) ^3 + 4.

This is because the function M(x) = 9cos(x)^3 represents a cosine function cubed, which results in a three-dimensional graph that oscillates and has multiple local maxima and minima. By translating the function one unit left, represented by the subtraction of 1 from the x value inside the cosine function, the entire graph is shifted one unit to the left.

The translation of 4 units up is represented by the addition of 4 to the overall function. This means that the entire graph of g(x) is now 4 units higher than the original function M(x).

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

Total number of prizes awarded = 3

Number of people entering the drawing competition = 15

Number of ways to award the prize = 2730

Out of the 3 prizes the first and the second is needed.

So, the prize for the first and the second positions are fixed and there is no need to consider the remaining 13 people to win the prize.

Hence the remaining number of people who can win the 3rd prize  = 13

The number of ways one of them wins the 3rd prize = 13

The total number of ways = 2730

Step-by-step explanation:

Area = πr²

        = π × 3²

        = 28.27

        = 28.3cm² (estimate to 3s.f always)

Circumference = 2πr

                          = 2 x π x 3

                          = 18.85

                          = 18.9cm (estimate to 3s.f always)

The area and the circumferences of the circle are 28.27 square meters and 18.85 meters.

Given is a circle with radius 3m we need to determine the area and the circumferences of the circle,

To determine the area and circumference of a circle with a radius of 3m, we can use the following formulas:

Area of a circle: A = πr²

Circumference of a circle: C = 2πr

Here, "r" represents the radius of the circle, and "π" (pi) is a mathematical constant approximately equal to 3.14159.

Let's calculate the values:

Area:

A = πr²

A = 3.14159 x (3m)²

A = 3.14159 x 9m²

A ≈ 28.27 square meters

Therefore, the area of the circle is approximately 28.27 square meters.

Circumference:

C = 2πr

C = 2 x 3.14159 x 3m

C ≈ 18.85 meters

Therefore, the circumference of the circle is approximately 18.85 meters.

Hence the area and the circumferences of the circle are 28.27 square meters and 18.85 meters.
