I think its 8×4√16

Explenation:

√128 = 11.3

√16×√8=6.3

8√2= 11.3

so i think you see the patern there and the answer should be 11.3 or 6.3

8√4×√2= 19

19÷2=9.5

9.5÷2=4.75

since 5 is too big to put in the equation and equal 128 then its 4.

To find the second one just do 4², which is 16

So yeah 8×4√16

Answer:

B) x=2y + 16

Step-by-step explanation:

First, you'd multiply the x/2 by 2 to get x by itself.

You do the same throughout the whole equation.

Then isolate the x by getting rid of the -16 to the other side by adding 16

Your final answer should be:

B) x=2y + 16

The value of x for the given equation x/2 - 8 = y will be x = 2y + 16 thus option (B) is correct.

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraints.

As per the given equation,

x/2 - 8 = y

Add 8 both sides,

x/2 - 8 + 8 = y + 8

x/2 = y + 8

Multiply by 2 both sides,

x/2 × 2 = (8 + y) × 2

x = 2y + 16

Hence "x = 2y + 16 will be the value of x in the equation x/2 - 8 = y".

The correct option is c. Analysis of variance.

ANOVA stands for Analysis of Variance, which is a statistical method used to test the equality of three or more population means by analyzing the variance between samples.

In an ANOVA, the variance is partitioned into different components, including the variance between groups and the variance within groups. If the variance between groups is larger than the variance within groups, it suggests that there are significant differences between the means of the groups being compared.

ANOVA is commonly used in experimental research to test the effects of one or more independent variables on a dependent variable. It allows researchers to determine whether the means of different groups are significantly different from one another, and if so, which groups are significantly different.

Overall, ANOVA is a powerful statistical tool that enables researchers to test hypotheses and draw conclusions about the differences between multiple groups or treatments.

The given statement: It is possible for a set of data to have multiple modes as well as multiple medians, but there can be only one mean is FALSE.

A set of data can have multiple modes, which are the values that occur most frequently in the dataset. For example, in a dataset of {2, 2, 3, 4, 4, 4}, the modes are 2 and 4 because they both occur three times.

A set of data can also have multiple medians, which are the middle values when the dataset is ordered from least to greatest. If the dataset has an even number of values, then there are two medians that represent the two middle values. For example, in a dataset of {2, 3, 4, 5}, the medians are 3 and 4.

However, a set of data can only have one mean, which is the average of all the values in the dataset. The mean is calculated by adding up all the values and dividing by the total number of values. Unlike modes and medians, the mean is sensitive to outliers or extreme values in the dataset, which can greatly affect the overall average.

Therefore, while a dataset can have multiple modes or medians, it can only have one mean.

Using Pythagorean Theorem, the length of the line segment from (-3, 10) to (4, -1) is 13 units.

Pythagorean theorem describes the relationship between the sides of a right triangle. It states that the square of the hypotenuse is equal to the sum of the squares of the two other side.

c² = a² + b²

Let a = vertical distance between the two points

b = horizontal distance between the two points

c = distance between the two points / length of line segment

Hence, c² = (|y₂ - y₁|)² + (|x₂ - x₁|)².

Substitute the values of x and y and solve for c.

c² = (|y₂ - y₁|)² + (|x₂ - x₁|)²

c² = (|-1 - 10|)² + (|4 - -3|)²

c² = (|-11|)² + (|7|)²

c² = 11² + 7²

c² = 121 + 49

c² = 170

c = 13.04

length of line segment ≅ 13 units

To solve the right triangle and find the length of the side adjacent to the given angle, follow these steps:

1. Identify the angle given in the problem. This angle is often labeled with a Greek letter, such as θ.

2. Determine which side of the triangle is adjacent to the given angle. The side adjacent to an angle is the side that is directly connected to that angle and not the hypotenuse.

3. Use the trigonometric function that involves the angle and the adjacent side. In this case, since we are finding the length of the side adjacent to the angle, we will use the cosine function.

4. Write down the cosine function and plug in the value of the given angle. The cosine function is defined as the ratio of the adjacent side to the hypotenuse. Let's call the length of the adjacent side "a" and the hypotenuse "h". The cosine function can be written as cos(θ) = a/h.

5. Rearrange the equation to solve for the length of the adjacent side (a). Multiply both sides of the equation by h to isolate "a". The equation becomes a = h * cos(θ).

6. Determine the value of the hypotenuse (h) if it is not given in the problem. If the hypotenuse is given, simply use that value.

7. Substitute the values of the hypotenuse (h) and the given angle (θ) into the equation. Multiply the hypotenuse by the cosine of the given angle to find the length of the adjacent side.

8. Round your answer to two decimal places as specified in the problem.

By following these steps, you will be able to find the length of the side adjacent to the given angle in the right triangle.

When Kp = 1.00 at 300K, for X(g) + Y(g) <==> Z(g), where [X] = [Y] = [Z] = 1.0 M, the reaction is in equilibrium.

Therefore the answer is c)  reaction is at equilibrium.

Given the equilibrium constant Kp = 1.00 at 300K, this means that the reaction is already at equilibrium. Therefore, the net reaction will not proceed in any direction. The concentration of all the species X, Y, and Z in the reaction mixture will remain constant. So the answer is [c] reaction is at equilibrium.

It's important to note that the equilibrium constant Kp is the product of the concentration of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients.

When Kp = 1, it means that the product of the concentrations of the products raised to their stoichiometric coefficients is equal to the product of the concentrations of the reactants raised to their stoichiometric coefficients. Therefore, the reaction is at equilibrium.

In the given figure, a circle with center Q is inscribed in triangle AHD.

Let the circle with center Q touches the side HD at point N.

So, AT & AM, DM & DN and HT & HN are tangents drawn from external points A, D and H respectively.

Since, measure of tangsnts drawn from external point to a circle are equal.

Therefore,

AM = AT = 18

HN = HT = 8

DM = DN = 12

AH = AT + HT = 18 + 8 = 26

AD = AM + DM = 18 + 12 = 30

HD = DN + HN = 12 + 8 = 20

Perimeter of triangle

To solve for t2 in the equation t2/t1=(p2/p1)^(n-1/n), we can cross-multiply to get t2=(p2/p1)^(n-1/n) * t1.


In the given equation, t2/t1 represents the ratio of two temperatures, while (p2/p1)^(n-1/n) is a ratio of pressures raised to a power. The exponent of (n-1/n) in the equation represents the ratio of specific heats, which is a constant value for a given gas. Thus, we can rewrite the equation as t2/t1= (p2/p1)^k, where k = (n-1/n).

To solve for t2, we can multiply both sides of the equation by t1, which gives us t2= (p2/p1)^k * t1.


Therefore, the equation to solve for t2 is t2= (p2/p1)^(n-1/n) * t1.

option A because rule of domains

Therefore, the center of pressure on the triangular sail is approximately (1.2, 0.9).

The center of pressure on a boat's sail that occupies a region R in the plane is given by

x = ∬R xydA/∬R ydA` and y = ∬R x²ydA/∬R xydA`.

To calculate the center of pressure on a triangular sail with vertices (0,0),(3,2) and (0,7) we will use the following formulas:

x = ∬R xydA/∬R ydA

y = ∬R x²ydA/∬R xydA

Remember that in this case, the region R in the plane is the triangular sail with vertices (0,0), (3,2), and (0,7).

Hence, the equations for x-bar and y-bar are:x-bar = ∬R xydA/∬R ydA= ∫(x=0 to x=3) ∫(y=0 to y=(7x/3))

=  xy dy dx/ ∫(x=0 to x=3) ∫(y=0 to y=(7x/3)) y dy dx= 42/35= 1.2 units (approx)

And,y-bar = ∬R x²ydA/∬R xydA= ∫(x=0 to x=3) ∫(y=0 to y=(7x/3)) x²y dy dx/ ∫(x=0 to x=3) ∫(y=0 to y=(7x/3)) xy dy dx= 63/70= 0.9 units (approx)

Answer:

28 and 12 . (QUORA)

Step-by-step explanation:

Let’s write this down. We are looking for X and Y.

The difference between two numbers is 16: −=16

Three times the larger number is seven times the smaller:  ∗3=∗7

So, we need to solve X and Y from these two equations.

If we re-arrange X*3 = Y*7, we get Y = X*3/7.

So, −∗3/7=16 .  −∗3/7  is the same as  7∗/7−3∗/7 , or  4∗/7 . So  4∗/7=16−>4∗=7∗16−>=7∗4=28 .

Then we just go back to  −=16 , and  =28 , gives us  28−=16,  or  =28–16−>=12 .

So the numbers are 28 and 12.

Step 1: Calculate the volume of the water in the first container.

The volume of a cylinder is V = πr^2h, where r is the radius of the cylinder and h is the height of the cylinder.

Therefore, the volume of the water in the first container is V = πr^2 x 15 cm, where r is the given radius of the container.

Step 2: Calculate the height of the water in the second container.

The volume of the water in the second container is the same as the volume of the water in the first container, since the same quantity of water is being poured from one container to the other.

Therefore, the volume of the water in the second container is also V = πr^2 x 15 cm, where r is now 2r, the radius of the second container.

To find the height of the water in the second container, we can substitute the value of the radius into the equation for the volume and solve for h. This gives us h = (15 cm) / (π(2r)^2), which simplifies to h = 15 cm / 4πr^2.
