Answer:

665280

Step-by-step explanation:

12x11x10x9x8x7=665280

There are 665280 ways in which 6 policemen can be appointed in 12 coaches of a passenger train if they are to ride in a separate coach.

Probability is defined as the branch of mathematics that deals with the numerical description of how likely an event is to occur, or how likely a proposition is to be true. The probability of an event is a number between 0 and 1, roughly where 0 indicates the improbability of the event and 1 indicates certainty.

It is based on the probable probability of something happening while the theoretical probability is based on the logic behind the probability. For example, if a coin is tossed, the theoretical probability of getting a head is ½.

In above example,

There are 6 policemen

Number of coaches assigned are 12

So, the number of ways are 12x11x10x9x8x7=665280 ways

Thus, there are 665280 ways in which 6 policemen can be appointed in 12 coaches of a passenger train if they are to ride in a separate coach.

Step-by-step explanation:

There are 3 cubes in the solid's length, 2 in its width, and 3 in its height. Therefore, the number of cubes = length * width * height = 3*2*3 = 18

The volume of a small cube , for a length l, is l³. The length is (1/3)m, so the volume is (1/3)³ = 1/27 m³

volume of solid = number of cubes * area of each cube = 1/27 * 18 = 18/27 m³. This is because we have to figure out the volume of 18 cubes together, and we can just add each cube to the volume 18 times for our answer

Considerando la estatura de Fernando, la longitud de su sombra y la distancia con respecto a la lámpara, la altura de la lámpara encendida es de 7.20 metros. (Opción correcta: A)

En la geometría Euclídea el concepto de proporcionalidad está asociado con el concepto de semejanza entre triángulos. Esta relación subyace en el hecho que si tenemos garantizado que existen un número suficiente y conocido de valores y características comunes entre los dos triángulos, entonces podemos determinar los valores faltantes.

En esta pregunta tenemos dos triángulos rectángulos que son semejantes, por ende, proporcionales. Por la definición de proporcionalidad derivamos la siguiente expresión para la altura de la lámpara:

Answer:

y = -3, x = 5

Step-by-step explanation:

In the first equation, x = 2 - y, x is on one side. So we can try to isolate the variable x in the second equation by adding 2y + 11 on both sides to get:

x = 2y + 11

So now we have equations x = 2 - y and x = 2y + 11. Therefore 2 - y = 2y + 11.  Now we isolate variable y by adding y on both sides and subtracting 11 on both sides to get -9 = 3y. Divide by 3 on both sides to get y = -3.

Let's substitute that into x = 2 - y. Since y = -3, we now have x = 2 - (-3) = 5.

An economic boom and bust occurred in the United States during the 1920s, which is also known as the Roaring Twenties.

This period was marked by a significant increase in consumer spending, economic growth, and technological innovation, particularly in the areas of automobiles, radio, and electricity. However, the boom came to an abrupt end with the stock market crash of 1929, which triggered the Great Depression of the 1930s.

The economic boom of the 1920s in the United States was a period of rapid economic growth and expansion, characterized by a surge in consumer spending, increased industrial production, and the expansion of credit. This period was fueled by a number of factors, including technological innovation, such as the widespread adoption of the automobile and the growth of the aviation industry, as well as the widespread availability of electricity.

The 1920s also saw significant changes in the social and cultural landscape of the United States, with the rise of a new consumer culture   that emphasized leisure and entertainment. The entertainment industry grew rapidly during this time, with the rise of radio broadcasting and the popularity of Hollywood films.

Answer: 4.8 miles a day

Step-by-step explanation:

Goal distance 23.2Miles

He rides 4miles, he is left with 23.2- 4= 19.2

Divide 19.2 into 4 days

Nathaniel needs to ride an average of 4.8 miles per day for the next 4 days to meet his goal of riding 23.2 miles this week.

Here, we have to find the average number of miles Nathaniel needs to ride each day to meet his goal, we can use the formula:

Average miles per day = (Total miles goal - Miles already ridden) / Number of days left

Let's plug in the values:

Total miles goal = 23.2 miles

Miles already ridden = 4 miles

Number of days left = 4 days

Now, we get,

Average miles per day = (23.2 - 4) / 4

Average miles per day = 19.2 / 4

Average miles per day = 4.8

So, Nathaniel needs to ride an average of 4.8 miles per day for the next 4 days to meet his goal of riding 23.2 miles this week.

Answer:

d ≤ -3

Step-by-step explanation:

Given that:

−13d + 6 ≤ 45

Solve:

Subtracting 6 from both sides

−13d + 6 ≤ 45

       -6    -6

-----------------------

−13d ≤  39

Multiply both sides by -1 which reverse the inequality

13d ≤ -39

Now divide both sides by 13

13d/13 ≤ -39/13

d ≤ -3

Thus the Answer is:

d ≤ -3

We can prove ∠Q ≅ ∠U, by showing the triangles congruent.

Given that a pair of triangles, ΔSQR and ΔTUR, connected at the point R, in which QR ≅ RU, SR ≅ RT.

We need to prove that ∠Q ≅ ∠U,

So, to prove the same we will use the concept of congruent triangles, the type of triangles in their corresponding parts are congruent, by showing the triangles congruent we can prove ∠Q ≅ ∠U.

1) QR ≅ RU, SR ≅ RT (given)

2) ∠QRS ≅ ∠TRQ (vertical angles are congruent)
