Answer: 270 students

Step-by-step explanation:

45% of the students joined a club, and there are 600 total students. To get 45% of 600, we just need to multiply 600 by the percentage in its decimal form, 0.45.

To find the fourth vertex of the rectangle, we can start by drawing a diagram:

========================================

        |

        |    (2,4)

        |

--------.--------

        |

(?, ?)   |    (2,1)

        |

========================================

We know that opposite sides of a rectangle are parallel, so the fourth vertex must be located on the same horizontal line as the point (2, 1) and the same vertical line as the point (-4, 4). Therefore, the fourth vertex must be located at (-4, 1).

To find the dimensions of the rectangle, we can find the distance between the points (2, 1) and (2, 4) to get the length of one side, and the distance between the points (2, 1) and (-4, 1) to get the length of the other side.

Length = 4 - 1 = 3

Width = 2 - (-4) = 6

So the dimensions of the rectangle are 6 by 3.

To find the area of the rectangle, we can multiply the length and width together:

Area = Length x Width = 6 x 3 = 18 square units.

Answer:

the water tower is 143 3/4 feet

Step-by-step explanation:

5ft 9in height

4ft silhouette

Convert 9in to ft = 9/12 so height = 5 9/12 = 23/4

Ratio of height to silhouette is (23/4) / 4

X = 100 the height of the building

Set up a proportion (23/4)/4 = X/100

X = 143 3/4 ft

Answer:

Step-by-step explanation:

1/2 = 3/6 (on time)      

1/3 = 2/6 (late)

1/6 = 1/6 (early)

3 times 2 is 6. You need the same denominators. What you do to the bottom you do to the top. So, 3x2=6 and 1x2=2. Therefore, you have 2/6. The 2 cubes can be used to show the probability of the train being late because we now know it is late 2/6 times and either early or on time 4/6 times.

Answer:

x > 7.5

Step-by-step explanation:

1. Multiply the reciprocal of 4/3 to both sides (3/4)

- x> 10/1 x 3/4

- x >30/4

2. Simplify the equation:

- x > 30/4

- x > 7 2/4

7 2/4 - 7.5

ANSWER = x > 7.5

To find the area of the parallelogram formed by the points (-5, 2), (2, 0), and (4, -4), we need to first find the fourth vertex of the parallelogram. Since opposite sides of a parallelogram are parallel and have equal length, the fourth vertex can be obtained by adding the vector formed by the points (-5, 2) and (2, 0) to the point (4, -4). This gives us the fourth vertex as (11, -6).

Next, we can use the distance formula to find the lengths of the two sides of the parallelogram. The length of the side connecting (-5, 2) and (2, 0) is sqrt(45), and the length of the side connecting (2, 0) and (4, -4) is 2sqrt(5).

Finally, we can use the formula for the area of a parallelogram, which is base times height, to find the area of the parallelogram. The base of the parallelogram is the distance of sqrt(45) between (-5, 2) and (2, 0), and the height is the distance of 2sqrt(5) between (2, 0) and (4, -4). Multiplying these values together gives us an area of 42 square units, which is option C.

Answer: x=1

Step-by-step explanation:

Since the angles are vertical that means they have to be equal.

So we can set the two equations equal to each other.

10 - x = 4x + 5

10 = 5x + 5

5 = 5x

x=1

Answer:

10 - x = 4x + 5

10 - 5 = 4x - x

     5  =  3x

      x = 1.6

         x = 1.6      

angle 1 =  10-1.6

            = 8.4

angle 2 = 4(1.6)+5

             = 11.4

Answer:

A. EAJ and IAH

Step-by-step explanation:

The answer is A. EAJ and IAH because if you notice, angle "EAJ" starts at "E", goes down to "A", and to the right to "J". Now, if you would again notice, angle "IAH" stars at "I", goes up to "A", and to the left to "H".

The definition of a verticle angle are angles opposite each other where two lines cross.

I have attacked an image below of an example of a verticle angle. If you would notice, the image of the vertical angle I attached looks the same as option "A. EAJ and IAH".

Answer: A square pyramid has 5 faces, 8 edges, and 5 vertices.

Step-by-step explanation:

The required answer is a square pyramid (excluding the base) has four faces. A square pyramid consists of a square base and triangular faces that meet at a common vertex.

To determine the number of faces excluding the base, we can follow these steps:

Step 1: Identify the number of triangular faces.

In a square pyramid, there are four triangular faces that connect each corner of the square base to the apex (the top vertex). These triangular faces do not include the base.

Step 2: Determine the total number of faces.

In addition to the triangular faces, we need to consider the base of the pyramid. The base is a square, and it is not counted when we exclude the base. Therefore, the number of faces excluding the base is the same as the number of triangular faces.

Step 3: Calculate the number of faces.

Since we determined that a square pyramid has four triangular faces, the square pyramid (excluding the base) has four faces.

Hence, a square pyramid (excluding the base) has four faces. A square pyramid consists of a square base and triangular faces that meet at a common vertex.

Answer:

Step-by-step explanation:

D

Step-by-step explanation:

The sample space for rolling two dice consists of 36 possible outcomes, as each of the six faces on the first die can be combined with any of the six faces on the second die.

To find the probability of showing either a prime number on the first die or a multiple of 5 on the second die, we can use the principle of inclusion-exclusion.

There are 3 prime numbers on a standard die: 2, 3, and 5. And there are two multiples of 5: 5 and 10. However, we need to be careful not to count the outcome (5,5) twice, as it satisfies both conditions.

So, the probability of showing either a prime number on the first die or a multiple of 5 on the second die is:

P(prime or multiple of 5) = P(prime) + P(multiple of 5) - P(prime and multiple of 5)

P(prime) = 3/6 = 1/2

P(multiple of 5) = 2/6 = 1/3

P(prime and multiple of 5) = 1/36

Therefore,

P(prime or multiple of 5) = 1/2 + 1/3 - 1/36

= 19/36

So the probability of showing either a prime number on the first die or a multiple of 5 on the second die is 19/36, or approximately 0.528.

In the context of this situation, the slope of -6.2 means that the temperature drops 6.2 degrees for every hour that passes. The negative sign indicates that the temperature is decreasing over time.

The y-intercept of 64 means that at hour 0 (the start of recording data), the temperature was 64 degrees. This is the initial value of the temperature, before any time has passed.

The slope and y intercept describes that

The slope applied to this situation is the temperature drops 6.2 degrees per hour. The y-intercept means at hour 0 (start of recording data), it was a temperature of 64 degrees.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have,

The line of best fit with the equation y = -6.2x + 64, where x represents the hour and y represents the temperature.

As, we know that the slope shows the rate of change of one quantity with respect to another quantity.

Here, the slope -6.2 tells us that the  temperature drops 6.2 degrees per hour.

and, the y intercept tells us that at 0 hour the temperature is 64 degree.

GOOD LUCK:)

The factorized value of the equation is solved and A = 4p² - 28pq

Brackets should be expanded in the following ways to factorize an expression

For an expression of the form A = a ( b + c ) , the expanded version is given by A = ab + ac, i.e., multiply the term outside the bracket by everything inside the bracket

For an expression of the form A = ( a + b ) ( c + d ) , the expanded version is given by A = ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second.

Given data ,

Let the expression be represented as A

Now , the value of A is

A = 4p ( p - 7q )

4p(p-7q) can be expanded as follows:

4p(p-7q) = 4p * p + 4p * (-7q)

A = 4p² - 28pq

Hence , the expanded form of 4p(p-7q) is 4p² - 28pq
