A shipping container will be used to transport several 120-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 27500 kilograms. Other shipments weighing 12400 kilograms have already been loaded into the container. Which inequality can be used to determine x, the greatest number of
120-kilogram crates that can be loaded onto the shipping container?

Answers

Inequality can be used to determine x, the greatest number of 120-kilogram crates that can be loaded onto the shipping container is  8000 + 120C <= 27500

What is inequality?

An inequality is a relationship that allows us to contrast two or more mathematical expressions.

Knowing that;

Each carton weighs 120 kg.

The container's maximum weight when loaded is 27500 kg.

Weight of the container as it is currently loaded: 8000 kg

Now that we have merged, we have;

Solution

because 8000 grams have already been loaded kilograms

into the container

each crate weighs 120 kilograms.

so 8000 + 120C <= 27500

Why are complex fractions called complex?.

Answers

Complex fractions are called complex because they contain one or more fractions within the numerator and/or denominator of the fraction. These fractions within the fraction make the fraction more complex or difficult to simplify than a regular fraction, which only has a single numerator and denominator.

The term "complex" in mathematics often refers to something that is composed of multiple parts or layers, and that requires more steps or understanding to work with or solve.

In this case, the presence of one or more fractions within the fraction makes it more complex than a regular fraction, hence the name "complex fraction."

Another reason for the term complex is that the fractions in the numerator and denominator may have different or even the same variables, making it difficult to cancel them or simplify the expression.

How do you graph inverse operations?.

Answers

The inverse operations can be graphed by determining the inverse of the function by swapping the x and y variables,

Not all functions have inverses, and in order for a function to have an inverse, it must be a one-to-one function that is, there must not be repeated output for many inputs which indicates that not all functions have inverses. The various steps to graph inverse functions can be noted as -

By switching the x and y variables, first determine the function's inverse, and then solve for y. The inverse function, for instance, will be x = f-1 if the original function is y = f(x) (y).By switching the original function's x and y values, plot the inverse function's points. For instance, if the original function is y = 2x + 1, the inverse function would be x = (y-1)/2, and instead of plotting the point (0,1), you would plot (1,0), (2,-1) and so on (-1,2)Over the line y = x, reflect the original function's graph. You will then be shown the inverse function's graph.Lastly, it is required to correctly identify the axes and the points.

How many solutions does Y =- 3x 5 have?.

Answers

The given equation y = -3x + 5 has infinitely many solutions.

We have linear equation y = -3x + 5

We need to encounter how many solutions can satisfy the given equation. 

We know that,

y = -3x + 5 is a linear equation in two variables in the form ax + by + c = 0

For x = 0, y = 0 + 5 = 5. Therefore, (0, 5) is one solution.

For x = 1, y = -3 × 1 + 5 = 2. Therefore, (1, 2) is another solution.

For y = 0, -3x + 5 = 0, x = 5/3. Therefore, (5/3, 0) is another solution.

Clearly, for different values of x, we get different values for y. Thus, any value substituted in the place of x in the given equation will form another solution for the given equation. So, there is no limitation to the number of different solutions obtained by substituting real values for x in the given linear equation. Thus, a linear equation in two variables can have infinitely many solutions.

Thus, y = -3x + 5 has infinitely many solutions.

What are the possible ways in which two consecutive odd numbers are added to sum of 2023?

Possible way in which two consecutive odd numbers are added to sum of 2023 is by evaluation using the formula (2n - 1) + (2n + 1) = 2023, so that we have 1010.5 + 1012.5 = 2023

What are consecutive odd numbers

Consecutive odd numbers are a sequence of numbers that are separated by a difference of 2 and are all odd numbers. For example the first four odd numbers are: 1, 3, 5, and 7. Odd numbers can be generated using the formula 2n -1.

We shall represent the first odd number with (2n - 1) so that the two consecutive odd numbers will be expressed as:

(2n - 1) + (2n + 1) = 2023

2n + 2n = 2023

4n = 2023

n = 2023/4 {divide through by 4}

n = 505.75

Therefore the two consecutive odd numbers added to sum of 2023 are derived as:

2(505.75) - 1 = 1010.5 and 2(505.75) + 1 = 1012.5

What is triangle ?

Triangle can be defined in which it consists of three sides , three angles and sum of three angles is always 180 degrees.

In the given triangle ,

Triangle STU ,

T = 90

S = 69

So, U = 180 - 90-69

U = 180 - 159

U = 21

And US  = 10

sin69 = TU/US

sin69 = TU / 10

0.93 = TU/ 10

93 / 100 = TU / 10

93/10 = TU

TU = 9.3

So, in the triangle

as per pythagores theorem ,

A graph must satisfy the vertical line test in order to be considered a function representation. The vertical line test requires that the line from the x-axis only once crosses an associated y-value.

The correct expression to solve te sum of polynomials is [(-3x)+(-8x)]+4x+[9+5] (D).

From the case, we have a problem as:

We can categorize each order:

Order 2 = (-3x²) and (-8x²)

Order 1 = 4x

Order 0 = 9 and 5

Word problems are often described verbally as instances where a problem exists and one or more questions are posed, the solutions to which can be found by applying mathematical operations to the numerical information provided in the problem statement. Determining whether two provided statements are equal with respect to a collection of rewritings is known as a word problem in computational mathematics.

Here total number of tickets = 516.

Which is contains adult and students tickets. Then let us take x is number of adult ticket and y is number of student tickets then,

=> x + y = 516 ------> 1

Now  there were 66 more student tickets sold than adult tickets then

=> y = x+66 -----> 2

Now put 2 into 1 then

=> x+66+x = 516

=> 2x = 516-66 = 450

Attendance i decreaing at a rate of 0. 5% per year. If there are 1200 people attending now how many will be attending in 4 year?

Answers

So, in 4 years, there will be 1176 people attending.

To find out how many people will be attending in 4 years, you need to determine the total decrease in attendance over that time period. The attendance is decreasing at a rate of 0.5% per year, so over 4 years, the decrease in attendance will be 4 years x 0.5% = 2%

To find out how many people will be attending in 4 years, you can then subtract the 2% decrease from the current attendance of 1200 people:

1200 x (1 - 0.02) = 1176 people
