Another equivalent equation to the equation (4x • 7)(5x • 9) is 28x(45x) respectively.

Equivalent equations in algebra are those that have equivalent roots or solutions.

In order to produce an equivalent equation, the same quantity or expression must be added to or subtracted from both sides of the original equation.

If you multiply or divide an equation's two sides by the same non-zero number, the results are identical.

If x4=2x+7, we can add 4 to both sides to get the following equation, which is equivalent: x4+4=2x+7+4.

So, we have the equation:

(4x • 7)(5x • 9)

Then, another equation that will be equivalent to the given equation can be:

(4x • 7)(5x • 9)

(28x)(45x )

Then,

28x(45x)

There are 462 different possible lineups of 5 songs that can be composed from the given list of 11 songs.

We need to use the idea of combinations to figure out how many different lineups of musical entertainment can be made. A way to select objects from a larger set without regard to their order is called a combination.

In this problem, we have to choose five songs from an 11-song list. We would like to know how many different ways there are for us to select five songs from the eleven that are available, where the order of the songs in the lineup is irrelevant. We can use the combination formula to solve this.:

n choose k = n! / (k! * (n - k)!)

where n is the total number of items to choose from, k is the number of items to choose, and ! denotes factorial, which is the product of all positive integers up to and including that number.

In this case, we have 11 songs to choose from and we want to choose 5 songs. So we can plug these values into the formula:

11 choose 5 = 11! / (5! * (11 - 5)!)

= (11 * 10 * 9 * 8 * 7) / (5 * 4 * 3 * 2 * 1)

= 11,880 / 120

= 462

Consequently, there are 462 unique potential setups of 5 tunes that can be created from the given rundown of 11 melodies.

Answer:

Step-by-step explanation:

The Unit Circle is a circle with a radius of 1 unit that is centered at the origin of a coordinate plane. It is often used in trigonometry to understand the relationships between angles, coordinates, and trigonometric functions such as sine, cosine, and tangent.

Special angles in trigonometry are angles that have commonly used values for their trigonometric functions. These special angles are 0 degrees, 30 degrees, 45 degrees, 60 degrees, and 90 degrees, and their corresponding angles in radians (which are the preferred units for angles in the Unit Circle). These angles have well-defined coordinates on the Unit Circle, and their sine, cosine, and tangent values can be easily determined.

To find the coordinates of points on the Unit Circle for special angles, we can use the following steps:

Start with the angle in radians. For example, if we are finding the coordinates for the angle of 30 degrees, we convert it to radians by multiplying by the conversion factor pi/180 (since there are pi radians in 180 degrees): 30 degrees * (pi/180) = pi/6 radians.

Identify the coordinates on the Unit Circle that correspond to the angle in radians. For example, for an angle of pi/6 radians, we know that it is located in the first quadrant of the Unit Circle, and the coordinates of the point where the angle intersects the Unit Circle are (cos(pi/6), sin(pi/6)).

Use the values of cosine and sine for the special angle from trigonometric tables or from memory. For example, the cosine of pi/6 radians is sqrt(3)/2, and the sine of pi/6 radians is 1/2.

Substitute the cosine and sine values into the coordinates of the Unit Circle. For example, for the angle of 30 degrees or pi/6 radians, the coordinates on the Unit Circle are (cos(pi/6), sin(pi/6)) = (sqrt(3)/2, 1/2).

Use the tangent function to find the tangent value of the special angle. The tangent function is defined as the ratio of sine to cosine: tan(theta) = sin(theta) / cos(theta). For example, for the angle of pi/6 radians, the tangent value is (sin(pi/6)) / (cos(pi/6)) = (1/2) / (sqrt(3)/2) = 1/sqrt(3).

In summary, special angles in trigonometry are used to determine the coordinates of points on the Unit Circle, and the sine, cosine, and tangent values of these special angles can be found using trigonometric tables or from memory, and then applied to the Unit Circle to determine the coordinates and trigonometric function values for these angles.

Step-by-step explanation:

The population will be approximately 29,628 people 5 years from now. (Rounded to the nearest whole number)

To calculate the future population, we need to take into account the growth rate over time.

In this case, we know that the population doubled in size over 26 months and the current population is 20,000.

Let's break down the problem step by step:

Calculate the monthly growth rate:

Since the population doubled in size over 26 months, the monthly growth rate can be calculated as the 26th root of 2.

This is because if the population doubles in size over 26 months, each month the population grows by the 26th root of 2.

Monthly growth rate  [tex]= 2^{(1/26) } \approx 1.027[/tex]

Calculate the number of months in 5 years:  

Since there are 12 months in a year, the number of months in 5 years is [tex]5 \times 12 = 60[/tex] months.

Calculate the future population:

We start with the current population of 20,000 and apply the monthly growth rate for 60 months.

Future population  = Current population [tex]\times[/tex]  (Monthly growth rate)^{(Number of months)

Future population [tex]= 20,000 \times (1.027)^60 \approx 29,628.12[/tex]

Therefore , the solution of the given problem of volume comes out to be the other leg of the right triangular pyramid's base is 12 yards long.

The volume of a three-dimensional item, which is measured in cubic units, describes how much room it occupies. Litre and in3 are the symbols for cubic measurements. However, in order to determine an object's dimensions, you must be aware of its volume. It's common practise to translate an object's weight onto metric units like kilogrammes.

Here,

Let's use "x" yards to represent the unknown leg of the right triangular pyramid's base.

A pyramid's volume can be calculated using the following equation: => => Volume = (1/3) * Base Area * Height

In this instance, the height of the pyramid is 14 yards, and its base is a right triangle with legs that are 8 yards and 'x' yards in length.

Consequently, we can formulate the equation for the pyramid's volume as follows:

=> 168 = (1/3) * (8 * x) * 14

The simplified formula gives us 168 = (4/3) * 14 * x.

We may find "x" by dividing both sides of the equation by

=> [(4/3)*14]: 168 / [(4/3)*14] = x.

=> x = 12

Therefore, the other leg of the right triangular pyramid's base is 12 yards long.

B + (B - 28) = 1176

Simplifying the above equation, we get:

2B - 28 = 1176

Adding 28 to both sides, we get:

2B = 1176 + 28

2B = 1204

Dividing both sides by 2, we get:

B = 602

Therefore, there are 602 boys in the school.

Here are two example data sets that meet the given conditions:

Data Set 1:

Values: 10, 12, 14, 16, 18, 20

Mean: (10+12+14+16+18+20) / 6 = 15

MAD: Mean Absolute Deviation = sum(abs(x - mean))/n = ((|10-15| + |12-15| + |14-15| + |16-15| + |18-15| + |20-15|)/6) = 2.5

Story: This dataset may have originated from measuring the time taken to complete a series of tasks by a group of skilled workers. The values represent the time taken in seconds, and the low MAD value indicates that the workers' performance was consistent. The mean value of 15 seconds suggests that the workers were efficient, completing the tasks quickly and accurately.

Data Set 2:

Values: 3, 5, 7, 9, 11, 13

Mean: (3+5+7+9+11+13) / 6 = 8

MAD: Mean Absolute Deviation = sum(abs(x - mean))/n = ((|3-8| + |5-8| + |7-8| + |9-8| + |11-8| + |13-8|)/6) = 2.5

Story: This dataset may have originated from measuring the height of a group of plants grown under different conditions. The values represent the height in inches, and the low MAD value indicates that the plants' growth was consistent across all conditions. The mean value of 8 inches suggests that the conditions were not optimal for plant growth, as the mean height is lower than the expected average for this type of plant.

Both data sets have a similar MAD value of 2.5, indicating that the variation in the data is relatively low, and the differences in the mean values suggest that they came from different sources. In both cases, the means are more than one MAD apart, indicating that there are significant differences between the values in each set.

Answer: To answer this question, we need to calculate the maximum possible speed of the train based on the given information and check if it is greater than 160 km/h.

First, let's use the given information to find the range of possible speeds of the train. The time taken by the train is given as 110 minutes, correct to the nearest 5 minutes. This means that the actual time taken by the train could be anywhere between 107.5 minutes and 112.5 minutes.

Converting the time to hours, we get:

Lower bound of time = 107.5 minutes = 107.5/60 hours = 1.792 hours

Upper bound of time = 112.5 minutes = 112.5/60 hours = 1.875 hours

Now, let's use the given distance of 270 km, correct to the nearest 10 km, to find the range of possible average speeds of the train. The lower bound of the distance is 265 km, and the upper bound is 275 km.

Lower bound of speed = 265 km / 1.875 hours = 141.3 km/h

Upper bound of speed = 275 km / 1.792 hours = 153.5 km/h

Therefore, based on the given information, the maximum possible speed of the train is 153.5 km/h, which is less than 160 km/h.

So, we can conclude that the average speed of the train could not have been greater than 160 km/h.
