Answer:

its the 2 option......................

The value of (M∪C)∩ V is { 3, 6 }

Sets are defined as a collection of well-defined elements, numbers or objects.

It is important to note that;

14.

M = { 2. 3 , 4 , 5}

C = { 4, 6 , 8 , 10}

V = { 3, 5 , 7 , 9}

M∪ C = { 2, 3, 4 , 5 , 6 , 8 , 10}

(M∪C)∩ V = { 3, 6 }

Thus, the value of (M∪C)∩ V is { 3, 6 }

Answer:

x=24

Step-by-step explanation:

again 180-156=24

super easy remember exterior +interior angles add up to 180

Brainliest please

First angle = 105

Second angle = x

Third angle = 156 - 105

= 51

_________________________________________

Three angles of the triangle:

[tex]105[/tex]

[tex]x[/tex]

___________________________________________

Angle sum of triangle = 180°

[tex]105 + 51 + x = 180[/tex]

[tex]156 + x = 180[/tex]

Answer:

Step-by-step explanation

Using the pythagoras theorem;

Given

The length of the flag pole = 8 feet = opposite side

Length of the rope = 10 feet = hypotenuse

To determine how far out on the ground he need to secure the rope from the flagpole so that the rope is tight, we need to look for the adjacent. Using the equation

hyp² = opp² + adj²

10² = 8² + adj²

adj² = 100-64

adj² = 36

adj = √36

adj = 6feet

Hence the rope should be placed 6feet out of the ground

The equation in slope-intercept form is  y = - 2x - 3.

The general equation of a straight line is

y = mx + c,

where m is the gradient or slope, and

y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

Now the given equation is,

10x + 5y = - 15

Dividing the equation by 5 we get,

2x  + y = - 3

Subtracting 2x both the side we get,

2x  + y - 2x = - 3 - 2x

⇒ y = - 3 - 2x

or, y = - 2x - 3

This is the required slope-intercept form.

where -2 is the slope and -3 is the intercept.

Thus, the equation in slope-intercept form is  y = - 2x - 3.

Answer: 39.4784

Step-by-step explanation:

The equation for area of a circle is (3.14)r^2.

Just plug in the given radius (4) into the equation and solve.

An ideal gas follows the ideal gas law stating PV = nRT. Obtain the average volume/mole by solving for V/n. Divide both sides by Avogadro’s constant Na. Multiplying n and Na gives the number of molecules N.   V/N is the average volume/molecule. 250C is the room temperature = 298.15K. The atmospheric pressure is 101325 Pa or 1 atm. Each molecule in a gas is spaced evenly and placed in a lattice. To obtain the space taken up by a cube, find the cube root of V/N to obtain the average intermolecular distance.  For small molecules such as N2 or H2, the angstroms order is 10^(-10)  m. The intermolecular distance is about 10 times the small molecules.

P V = nRT

V⁄n=RT⁄P

V⁄(nNa )=RT⁄(PNa )

V⁄N=((8.314 J/(mol.K))(298.15K))/((101325Pa)(6.02×10^23  molecules/mol))≈4.06×10^23  m^3/molecule

∛(V/N)≈3.44×10^(-9) m = 3.44 nm

The intermolecular distance is about 10 times the small molecules.

Answer:

x ≥ 2 3/4

Step-by-step explanation:

6 ≤ x + 3 1/4

6 - 3 1/4 ≤ x

2 3/4 ≤ x

x ≥ 2 3/4

The solution to that equation or inequality will be; x ≥ 2 3/4

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

WE have been given that Six is less than or equal to the sum of a number and 3 1/4;

Therefore, the inequality will be;

6 ≤ x + 3 1/4

6 - 3 1/4 ≤ x

2 3/4 ≤ x

x ≥ 2 3/4

Hence, The solution to that equation or inequality will be; x ≥ 2 3/4
