The solution of the equation are as follows:

y = 15

v = 28

r = 95.5

m = 30

d = 54

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.  The equation can be solved by finding the value of the variables.

A variable is a number represented with letter in an equation.

Therefore, let's solve the equation.

y + 4 - 1 = 18

y = 18  - 4 + 1

y = 15

v - 7 = 9 + 12

v = 12 + 9 + 7

v = 28

53.5 + 44 = 2 + r

r = 53.5 + 44 - 2

r = 95.5

m + 18 + 23 = 71

m = 71 - 18 - 23

m = 30

22 + 15 = d - 17

d = 22 + 15 + 17

d = 54

13/16 as a decimal rounded to the nearest tenth is 0.8.

A decimal is a way to represent the same thing but in a different form. In this case, we will convert the fraction 13/16 into a decimal and round it to the nearest tenth.

To convert a fraction to a decimal, we divide the numerator (top number) by the denominator (bottom number). In this case, 13 divided by 16 is equal to 0.8125. This means that 13/16 as a decimal is 0.8125.

To round a decimal to the nearest tenth, we look at the digit in the hundredths place (the second digit after the decimal point).

If this digit is 5 or greater, we round up the tenths place (the first digit after the decimal point). If it is less than 5, we leave the tenths place as is. In this case, the digit in the hundredths place is 2, which is less than 5.

Therefore, we leave the tenths place as is, and the final answer is 0.8.

As (-2, 2) and (4, -1) lie on a line the equation of the line is: y = (-1/2)x + 1

We can use the slope-intercept form of a linear equation,

which is y = mx + b, where m is the slope and b is the y-intercept.

First, we need to find the slope of the line using the two given points. The slope formula is:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Plugging in the values, we get:

m = (-1 - 2) / (4 - (-2)) = -3/6 = -1/2

Now we have the slope (m = -1/2), and we can use either of the two given points to find the y-intercept (b).

Let's use the first point (-2, 2):

y = mx + b

2 = (-1/2)(-2) + b

2 = 1 + b

b = 1

So the equation of the line is:

y = (-1/2)x + 1

The blue box measures about 641.667 cm in length.

The width and length of a figure indicate its breadth and length, respectively. The term "breadth" is also used to describe width. Although breadth and width are synonymous (thus the idiom hair's breadth, denoting a very small width), there are two significant differences between the two.

We are aware that the blue box's width is 18 cm, which is smaller than the green box's width (70cm).

As a result, the value of "k" must be lower than 1. By creating a proportion, we can determine the value of "k":

width of green box / width of blue box = k

70 / 18 = k

k = 70/18

k ≈ 3.8889

So the factor "k" is approximately 3.8889. To find the length of the blue box, we can use this factor to scale the length of the green box:

length of blue box = k * length of green box

length of blue box = 3.8889 * 165cm

length of blue box ≈ 641.667cm

Answer:

The expression is a summation, or the sum of a sequence of terms. Each term is equal to 900 * (1.04)^n+1, where n starts at 1 and goes up to infinity.

To calculate this sum, we would need to find the limit of the sequence as n approaches infinity. However, finding the exact value of this sum is not possible and would require the use of mathematical tools like mathematical analysis.

To estimate the value, we can use a calculator or spreadsheet to calculate the sum for a finite number of terms and then see how the sum changes as we increase the number of terms. For example, if we calculate the sum for n = 1 to 100, we would get an estimate of the value. If we then calculate the sum for n = 1 to 200, we would get a closer estimate.

In this case, we can round the expression to the nearest integer, which would be 53.

Referring to the given kite, the length of the other diagonal. DF, is 21 cm.

A kite is a quadrilateral shape, meaning it has four sides. The two pairs of adjacent sides are of equal length, while the opposite sides are not.

The shape of a kite is typically described as having two pairs of congruent adjacent sides that are connected by two diagonal lines that intersect at a right angle. The diagonal lines of a kite are perpendicular to each other, and the shorter diagonal bisects the longer diagonal.

Let's denote the point of intersection of the two diagonals as O.

Since the two diagonal intersect at a right angle, diagonal DF is perpendicular to diagonal EG.

DG = 13 cm

FG = 20 cm

OG = 1/2 EG = 1/2 x 24 = 12 cm

Using the Pythagorean Theorem:

OD = √(DG² - OG²)

     = √(13² - 12²) = 5 cm

OF = √(FG² - OG²)

     = √(20² - 12²) = 16 cm

DF = OD + OF

Step-by-step explanation:

No, we would not expect about 95% of the samples to have their variances within 0.008 of 0.009.

The variance of a normal distribution with mean μ and variance σ^2 is given by σ^2, which in this case is equal to (0.004)^2 = 0.000016.

The variance of the sample means, on the other hand, is given by σ^2/n, where n is the sample size. In order for about 95% of the samples to have variances within 0.008 of 0.009, we would need the sample size to be approximately equal to:

n ≈ σ^2 / (0.008 - 0.009)^2 = 62500

This means that we would need very large samples for this to be true. However, if the sample size is relatively small, then the distribution of sample means will not necessarily be normal and the Central Limit Theorem may not apply.

In that case, the distribution of sample variances will not necessarily follow the same pattern as the distribution of the population variance, and it may not be possible to make predictions about the sample variances based on the population parameters.

The different values in the row of the table are: 1. l = 2π²r/ 2160, A = π²r²/ 2160. 2. α = 60/r and sector area A = πr/60.

The sector is essentially a section of a circle, and it may be described using the following three criteria:

The area of a disc that is surrounded by two radii and an arc is known as a circular sector.

The circle is divided into the Major Sector and the Minor Sector by a sector.

The region with a lesser extent is referred to as the Minor Sector, whereas the territory with a larger area is referred to as the Major Sector.

Given that,

Central angle = [tex]\frac{\pi}{6}[/tex].

The arc length is given as:

l = α/360 (2πr)

Where, α is the central angle.

Substitute the value of central angle we have:

l = (π/6)/360 2πr

l = 2π²r/ 2160

The sector area is given as:

A = α/360  πr²

A = (π/6)/360 πr²

A = π²r²/ 2160

Similarly, the arc length is given as:

l = π/3

Substituting the value of l in arc length we have:

π/3 = α/360 (2πr)

α = 360(π)/ 6πr

α = 60/r

The sector area is given as:

A = α/360  πr²

A = (60/r) 360 πr²

A = πr/60

Hence, the different values in the row of the table are: 1. l = 2π²r/ 2160, A = π²r²/ 2160. 2. α = 60/r and sector area A = πr/60.

Total hours handled by x judges in the year ≤ 12120x where x is the number of judges needed to handle the caseload for the year.

To formulate an LP for this problem, we can define the decision variables and the objective function and constraints.

Decision Variables:

Let x be the number of judges needed by the city to handle the caseload for the year.

Objective Function:

We want to minimize the number of judges needed, so our objective function is:

minimize x

Constraints:

Each judge can handle up to 120 hours of caseload per month, so the total number of hours that can be handled by x judges in a month is 120x. The total number of hours needed to handle the caseload for the year is given in the table. Therefore, we have the following constraints:

For January: 120x ≥ 100

For February: 120x ≥ 120

For March: 120x ≥ 90

For April: 120x ≥ 80

For May: 120x ≥ 110

For July: 120x ≥ 140

For August: 120x ≥ 110

For September: 120x ≥ 100

For October: 120x ≥ 90

For November: 120x ≥ 80

For December: 120x ≥ 120

These constraints ensure that the total number of hours handled by the judges in each month is at least as much as the number of hours needed to handle the caseload in that month.

We also need to ensure that all cases are handled by the end of December. This can be expressed as follows:

Total hours handled by x judges in the year ≤ 12120x

This constraint ensures that the total number of hours handled by the judges in the year is less than or equal to the maximum possible number of hours that can be handled by x judges in a year.

Therefore, the LP can be formulated as follows:
