Inequality 5 > 6 is an example of an inequality whose solution is an empty set.

What is inequality?

An inequality is a statement that compares two expressions using one of the following mathematical symbols: <, >, ≤, ≥, ≠. It shows the relationship between the values of the expressions, but unlike an equation, it does not show that the expressions are equal.

For example, the inequality 3x + 4 > 7 compares the value of the expression 3x + 4 to the value of 7. It shows that 3x + 4 is greater than 7 for all values of x.

An inequality that has an empty set as its solution is one that has no solutions. For example, inequality 5 > 6 is an example of an inequality whose solution is an empty set because it is impossible for any value of x to satisfy the inequality. Any value of x will be less than 6 so it is impossible for x to be greater than 6.

Hence, Inequality 5 > 6 is an example of an inequality whose solution is an empty set.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given this, Kayak and canoe experiences are led by a river guide along a beautiful river. In addition to a booking fee and a variable tariff based on the number of passengers, he charges. The graph displays the total cost for various passenger counts, including the booking fee.

From general formula of rate of change = (y₂ - y₁)/ (x₂ - x₁)

The current weight of Aadan's dog is approximately 26.67 kg.

What is weight ?

Weight is a measure of the force of gravity on an object. The weight of an object is equal to the force exerted on the object by gravity. The weight of an object is typically measured in units of force such as newtons (N) or pounds (lb). On Earth, the weight of an object is equal to its mass multiplied by the acceleration due to gravity, which is approximately 9.8 m/s².

Let's call the current weight of Aadan's dog as "W".

As per the information given,

Aadan's dog was a puppy and it weighed 8 kg which is 30% of it's current adult weight.

So, 8kg = 30/100*W

We can find the current weight of Aadan's dog by solving the equation above:

8 = 30/100W

8 = 3/10W

8 = 0.3W

W = 8/0.3

W = 8/(3/10)

W = 8(10/3)

W = 8*3.333

W = 26.666 kg ( approx 26.67 kg)

So the current weight of Aadan's dog is approximately 26.67 kg.

What does the division do?

divides left-hand operands into right-hand operands while performing a division operation in mathematics.

For instance, 4/2 = 2.

She combined the prescribed amounts of 1 2/5 litres of cranberry juice and 1 3/5 litres of pineapple juice.

The appropriate response to the aforementioned situation would be

⇒ 1 2/5 + 1 3/5

fractionalizing mixed numbers

⇒ 7/5 + 8/5

Consider the LCM in the previous equation.

⇒ (7 + 8)/5

⇒ 15/5

⇒ 3

She then divided the fruit punch equally among the nine cups.

Answer: Is there an answer for 1/2? I'm not sure.

Step-by-step explanation: If you look at the line it's going up by one and over by 2.

To solve for slope (Rate of Change) you need to find the change and y over the change in x. (y2-y1) divided by (x2-x1) take two points on the graph that is touching a line.

Two points on your graph is (2,2), and (6,4). You would take the second y which is 4 and subtract it from the first y which is 2. (4-2 = 2). Then you take the second x (6) and subtract it from the second y (2). (6-2 = 4). Now that you have the change and x over the change in y. you divide the top number by the bottom number. If it's a fraction just simplify it. (2/4 = 1/2). I'm not that good at explaining but I hope this helps a lot!

A unit rate is a ratio that has a denominator of 1, such as miles per hour or dollars per item. To solve a complex fraction that involves a unit rate, you can follow the same steps as solving a regular complex fraction, but with an additional step to convert the final expression to a unit rate.

Factor the numerator and denominator of the complex fraction if possible.

Multiply both the numerator and denominator by the reciprocal of the fraction(s) in the denominator.

Simplify the resulting expression by combining like terms, if possible.

Check your work by multiplying the numerator and denominator of the original complex fraction by the reciprocal of the fraction(s) in the denominator, and verifying that the simplified expression you obtained is equivalent.

Divide the numerator by the denominator to get the unit rate.

Answer:

31.875 m

Step-by-step explanation:

We can begin solving the problem by using the formula for the volume of a cylinder and the volume of a cone.

The volume of the well is given by the formula for the volume of a cylinder:

V = πr^2h

where r is the radius of the well (half the diameter, which is 3/2 = 1.5 m) and h is the depth of the well (21 m).

V = π(1.5)^2(21) = 42.5π m^3

The embankment is formed by the earth that was dug out of the well, and it has the shape of a cone. The volume of the cone is given by the formula:

V = 1/3 πr^2h

where r is the radius of the base of the cone (4 m) and h is the height of the embankment.

V = 1/3π(4)^2h = 4/3πh m^3

Now we know that the volume of the embankment is equal to the volume of the well:

V = 42.5π m^3 = 4/3πh m^3

Then we can solve for h by dividing both sides by 4/3π:

h = 42.5π m^3 * 3/4π = 31.875 m

So the height of the embankment is 31.875 m.

a. You replace each card before selecting the next card.

The probability of drawing a heart on the first draw is 13/52 or 1/4. The probability of drawing a heart on the second draw is also 13/52 or 1/4. And the probability of drawing a heart on the third draw is also 13/52 or 1/4.

Since the events are independent, we can multiply the probability of each event to find the probability that all three cards are hearts: (1/4) * (1/4) * (1/4) = 1/64.

b. You do not replace each card before selecting the next card.

The probability of drawing a heart on the first draw is 13/52 or 1/4. The probability of drawing a heart on the second draw is 12/51 since we already drew a heart before, the total number of cards left in the deck is 51. The probability of drawing a heart on the third draw is 11/50 since we already drew 2 hearts before, the total number of cards left in the deck is 50.

The probability that all three cards are hearts is (1/4) * (12/51) * (11/50) = 0.0217 or approximately 2.17%.

It's important to note that in the first case the probability of drawing a heart on the second and third draw is still 1/4 because we are replacing the cards back before drawing the next one, so all 52 cards are available again. While on the second case, we don't replace the cards back and that's why the probability of drawing a heart on the second and third draw is different.Answer:

The inverse function of f(x) = x^3 - 1 is f^-1(x) = (x + 1)^(1/3).

What is the inverse of a function?

An inverse function is a function that returns the original value for which a function has given the output. If f(x) is a function that gives output y, then the inverse function of y, i.e. f-1(y) will return the value x.

The inverse of a function f(x) is denoted as f^-1(x), and it is defined as the function that "undoes" f(x).

To find the inverse of a function, we need to swap the roles of x and y, and then solve for y in terms of x.

Given f(x) = x^3 - 1, the inverse function f^-1(x) is the function such that:

f(f^-1(x)) = x

f^-1(f(x)) = x

So we need to solve for x in terms of y.

x^3 - 1 = y

x = (y + 1)^(1/3)

Therefore, the inverse function of f(x) = x^3 - 1 is f^-1(x) = (x + 1)^(1/3).

The solutions of the equation x⁴ - 5x² - 36 = 0 are: x = -3, x = 3, x = 2i and x = -2i

Consider given equation x⁴ - 5x² - 36 = 0

Let us assume that x² = p

so, we get an equation,

p² - 5p - 36 = 0

Now we solve above quadratic equation.

p² - 5p - 36 = 0

using the Quadratic Formula where

a = 1, b = -5, and c = -36

[tex]\Rightarrow p=\frac{-b\pm \sqrt{b^2 -4ac} }{2a}\\\\\\ \Rightarrow p = \frac{5\pm \sqrt{25+144} }{2}\\\\\\\Rightarrow p = \frac{5\pm \sqrt{169} }{2}\\\\\\ \Rightarrow p=\frac{5\pm 13 }{2}[/tex]

So, p = 9 and p = -4

But p = x²

So, x² = 9 OR x² = -4

For x² = 9, by taking square-root we get x = 3, x = -3
