The number of chickens that can be fed with 140 kg of corn is 2800.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 8 is an equation.

We have,

250 kg corn  = 5000 chicken

Multiply 140/250 on both sides.

140 kg of corn = 140/250 x 5000 chicken

140 kg of corn = 2800 chicken

Thus,

2800 chickens can be fed with 140 kg of corn.

Answer: In this scenario, the length of the backpacking trip is the independent variable and the amount of trail mix Wesley will bring is the dependent variable.

The independent variable is the variable that is being changed or controlled in an experiment or study. In this case, the length of the backpacking trip is the independent variable because it is being determined by Wesley and is not influenced by any other factor.

The dependent variable is the variable that is being measured or observed in an experiment or study. In this case, the amount of trail mix Wesley will bring is the dependent variable because it depends on the length of the backpacking trip. Wesley's decision on how much trail mix to bring will be influenced by how long he plans to go backpacking.

The solution of the trigonometric equation is x = 26.57° or 153.43°

A trigonometric equation is an equation that contains the trigonometric ratios.

Given the trigonometric equation 2cos x - sin x = 3/(2cos x + sin x)

We solve for x in the equation. We proceed as follows.

Since 2cos x - sin x = 3/(2cos x + sin x)

Multiplying both sides by (2cos x + sin x), we have that

(2cos x - sin x)(2cos x + sin x) = 3

Now, we know that (a² - b² = (a + b)(a - b)

Applying this where a = 2cosx and b = sinx, we have that

(2cos x - sin x)(2cos x + sin x) = 3

(2cos x)² - (sin x)² = 3

4cos² x - sin² x = 3

Since sin²x = 1 - cos²x, substituting this into the equation, we have that

4cos² x - sin² x = 3

4cos² x - (1 - cos²x) = 3

4cos² x - 1 + cos²x = 3

4cos² x + cos²x  = 3 + 1

5cos²x  = 4

cos²x  = 4/5

Taking square root of both sides, we have that

cosx  = ±√(4/5)

cosx  = ±2/√5)

cosx  = ±2/√5 × √5/√5

cosx  = ±2√5/5

Taking inverse cosine of both sides, we have

x = cos⁻¹(±2√5/5)

x = cos⁻¹(±0.8944)

x = cos⁻¹(0.8944) or x = cos⁻¹(-0.8944)

x = 26.57° or (180 - 26.57)°

x = 26.57° or 153.43°

So, the solution is x = 26.57° or 153.43°

The slope of the given line is 40 mi/h.

How to find slope of the line in the graph?

The slope of a line is the ratio of rise to run. Hence, here are the steps to find slope from a graph.

Select any two random points on the graph of the line (preferably with integer coordinates).

Label them as A and B (in any order).

Calculate the "rise" from A to B. While going vertically from A to B, if we have to go

"up", then the rise is positive;

"down", then the rise is negative.

Calculate the "run" from A to B. While going horizontally from A to B, if we have to go

"right", then the run is positive;

"left", then the run is negative.

Now, use the formula: slope = rise/run.

According to the given question:

To calculate the slope of the line in given graph let point A be (5, 200) and point B (10, 400).

Run = 5

Rise = 200

Therefore, slope = rise/run = 200/5 = 40 mi/h

Both a smaller and a bigger number are 25 and 68

The outcome or conclusion we get at when we add two or more integers is known as the SUM. example the total of the addends, 6, and 4, is 10. In other words, we may argue that 8 plus 5 equals 13 or that 8 plus 5 equals 13.

Here, we've been given two numbers, one smaller and one bigger, where the smaller number is X and the larger number is 18  more than twice the smaller number.

2X + 18 is the greater number.

Because the total is now 93, X + (2X+18) = 93

3X = 93 - 18 .

X = 25

larger number will be 2(25) + 18 = 68

The probability that the card has a multiple of 3 is 5/16. We use the concept of probability and multiples to get the answer.

Probability of an event = (no of possible ways it can happen) / (total number of outcomes)

For instance, 20 is a multiple of 4 and 5 if we declare that 4 + 5 = 20. The remaining multiples of four can be written as follows: 4, 8, 12, and so on. Four times one equals four. Numerous other mathematical ideas can be explored with the aid of multiples knowledge.

Given, total number of the cards in the bag is from 1 to 16.

So, total number of cards = 16.
