Answer:

x is equal to six

Step-by-step explanation:

4 × 6 = 24

Answer: There is only one step to this equation. We will use inverse operations to isolate the x by dividing 4 on both sides. (4 is being multiplied by x, and the opposite of multiplication is division.)

4x/4 = x

24/4 = 6

The equation now looks like:

x = 6

x is equal to 6, so this is your answer.

The linear distance traveled in one revolution of a wheel can be calculated using the formula:

Circumference = π * Diameter

Given that the diameter of the wheel is 36 inches, we can substitute the value into the formula:

Circumference = π * 36 inches

Using an approximate value of π as 3.14159, we can calculate the circumference:

Circumference ≈ 3.14159 * 36 inches

Circumference ≈ 113.09724 inches

Therefore, the linear distance traveled in one revolution of a 36-inch diameter wheel is approximately 113.09724 inches.

It cannot be determined. At least one other point on the line is needed to determine if x is proportional to y

Given data ,

A point on a straight line has an x-coordinate of 3 and a y-coordinate of 6

Now , A single point on a straight line does not define the connection between x and y. We must evaluate the connection between x and y for several places on the line in order to establish if x is proportional to y.

As a result, the relationship between x and y cannot be inferred only from the supplied location (3, 6). To establish the proportionality between x and y, at least one more point on the line is required

Answer:

x=13     y=54

Step-by-step explanation:

9x-7=7x+19

2x=26

x=13

180-(9*13  -7)=y+16

180- 110 = y+16

70=y+16

54=y

Answer:

x = 13, y = 54

Step-by-step explanation:

( 9x - 7 ) and ( 7x + 19 ) are vertically opposite angles. Vertically opposite angles are equal since line m and n are parallel.

9x - 7 = 7x + 19

9x - 7x = 19 + 7

2x = 26

x = 26 / 2

x = 13

7x + 19

= ( 7 ) ( 13 ) + 19

= 91 + 19

= 110

( 7x + 19 ) and ( y + 16 ) are linear pair angles. Sum of linear pair angles is 180,

y + 16 + 7x + 110 = 180

y + 16 + 110 = 180

y + 126 = 180

y = 180 - 126

[1] Mass of evaporating dish #1: 36.190 g

[2] Mass of evaporating dish and original sample: 37.020 g

To calculate the mass of the original sample, we subtract the mass of the evaporating dish from the total mass:

Mass of original sample = Mass of evaporating dish and original sample - Mass of evaporating dish

Mass of original sample = 37.020 g - 36.190 g

Mass of original sample = 0.830 g

[3] Mass of evaporating dish after subliming NH4Cl(g): 36.550 g

To calculate the mass of NH4Cl(g), we subtract the final mass of the evaporating dish from the initial mass:

Mass of NH4Cl(g) = Mass of evaporating dish - Mass of evaporating dish after subliming NH4Cl(g)

Mass of NH4Cl(g) = 36.190 g - 36.550 g

Mass of NH4Cl(g) = -0.360 g (Note: The negative value indicates an error in measurement or calculation. Please double-check the data provided.)

To calculate the percent of NH4Cl (%), we use the formula:

Percent of NH4Cl = (Mass of NH4Cl(g) / Mass of original sample) * 100

Percent of NH4Cl = (-0.360 g / 0.830 g) * 100

Percent of NH4Cl = -43.37% (Note: The negative value also suggests an error. Please review the data carefully.)

Moving on to the determination of Sodium Chloride:

[4] Mass of evaporating dish #2: 41.63 g

[5] Mass of watch glass: 47.84 g

[6] Mass of evaporating dish #2, watch glass, and NaCl(g): 89.510 g

To calculate the mass of NaCl(g), we subtract the sum of the masses of the evaporating dish #2 and the watch glass from the total mass:

Mass of NaCl(g) = Mass of evaporating dish #2, watch glass, and NaCl(g) - (Mass of evaporating dish #2 + Mass of watch glass)

Mass of NaCl(g) = 89.510 g - (41.63 g + 47.84 g)

Mass of NaCl(g) = 89.510 g - 89.47 g

Mass of NaCl(g) = 0.040 g

To calculate the percent of NaCl (%), we use the formula:

Percent of NaCl = (Mass of NaCl(g) / Mass of original sample) * 100

Percent of NaCl = (0.040 g / 0.830 g) * 100

Percent of NaCl = 4.82%

A simple random sample of 500 voters would be an appropriate method for a pollster to use in this situation.

In this method, each voter in the town is assigned a unique identifier and a list of all unique identifiers is created. Then, using a random number generator or a random number table, 500 unique identifiers are selected and those individuals are surveyed.

This method ensures that each voter in the town has an equal chance of being selected, so that the sample is representative of the population of voters. It also eliminates any potential biases that may be introduced if the pollster were to select individuals based on certain criteria (such as age, gender, or location).

By using a random sample, the pollster can have a good estimate of the true population parameter (voter preferences) with a high degree of confidence.

Answer: 19 questions wrong, 16 questions right

Step-by-step explanation:

The time before the two friends can shake hands can be determined by finding the time it takes for the second friend to cover the initial distance of 50 m while accelerating uniformly.

Using the equation of motion s = ut + (1/2)at^2, where s is the distance, u is the initial velocity, a is the acceleration, and t is the time, we can solve for t.

For the first friend, who is walking at a constant speed of 0.50 m/s, the distance covered is given by s1 = u1t, where u1 = 0.50 m/s.

For the second friend, who is accelerating uniformly from rest, the distance covered is given by s2 = (1/2)at^2, where a = 1.0 m/s^2.

Since they will meet when their distances covered sum up to the initial distance of 50 m, we can set up the equation: s1 + s2 = 50 m.

Substituting the expressions for s1 and s2, we get (0.50t) + (1/2)(1.0t^2) = 50.

Simplifying and rearranging the equation, we have 0.50t + 0.50t^2 = 50.

Solving this quadratic equation will give us the time it takes for the two friends to shake hands.

Now, let's explain the process in more detail. The first friend is walking at a constant speed of 0.50 m/s, so the distance covered by the first friend is given by the product of the speed and time, s1 = 0.50t.

The second friend starts from rest and accelerates uniformly at a rate of 1.0 m/s^2. We can use the equation of motion s2 = (1/2)at^2, where s2 is the distance covered by the second friend.

To find the time it takes for the second friend to cover the distance, we set up the equation s1 + s2 = 50, as the sum of the distances covered by both friends should equal the initial distance of 50 meters.

Substituting the expressions for s1 and s2, we get 0.50t + (1/2)(1.0t^2) = 50.

This equation is quadratic in nature, and solving it will give us the time it takes for the two friends to shake hands.

By solving the equation, we find the value of t to be approximately 10.77 seconds. Therefore, the two friends can shake hands after approximately 10.77 seconds.

We can use the radical rules to simplify the product 3(4x2). To start, we simplify 4 to its square root, which equals 2. Next, we employ the power property of radicals, which asserts that (a,m) = (a(m/2)), to simplify the cube root (x2) by using it. In this instance, (x2) = x.

We now get 3 * 2 * x, which simplifies to 6x when the simpler terms are combined.The result is that the product 3(4x2) has the simplest form (6x).We can dissect the constituent parts and use the radical-simulation principles to simplify the product 3(4x2).In the beginning, we may reduce the square root of 4 to 2: 3(2x2).Then, since it contains a square (2) and a cube root (), we can reduce them as follows:

3 * 2 * x^(²/³)Taking the square root before the cube root is shown by the exponent 2/3. We may calculate the exponent by reducing it to: 3 * 2 * x(2/3)The terms are then combined when we multiply the coefficients: 6 * x(2/3)As a result, 6x(2/3) is the product of 3(4x2) in its simplest form.
