The value of GI is approximately B. 77. Hence, the correct answer is B. 77.

Based on the given information and the similarity of triangles ^GHI and ^JKL, we can use the concept of proportional sides to find the value of GI.

We have the following information:

JP = 35

MH = 33

PK = 15

Since the triangles are similar, the corresponding sides are proportional. We can set up the proportion:

GI / JK = HI / KL

Substituting the given values, we get:

GI / 35 = 33 / 15

Cross-multiplying, we have:

GI * 15 = 33 * 35

Simplifying the equation, we find:

GI = (33 * 35) / 15

GI ≈ 77

Therefore, the value of GI is approximately 77.

Hence, the correct answer is B. 77.

x=2

Step-by-step explanation:

5x-1=3x+3

2x-1=3

2x=4

x=2

Answer:

x = 2

Step-by-step explanation:

We can say that both the triangles are congruent by the "if two angles of given triangles are congruent then the triangles are congruent" theorem, so we can set both equations equal to each other:

5x - 1 = 3(x + 1)

=> 5x - 1 = 3x + 3

=> 2x - 1 = 3

=> 2x = 4

=> x = 4/2

=> x = 2

We would then compare the calculated test statistic to the critical value at the chosen significance level (e.g., α = 0.05), and make a decision to reject or fail to reject the null hypothesis based on the result.

For this situation, we would use the one-sample proportion test.

Procedure: One-sample proportion test

Test statistic: z

No. of degrees of freedom: Not applicable

The null and alternative hypotheses would be:

H0: p = 0.6 (The union does have the required 3 to 2 majority)

Ha: p < 0.6 (The union does not have the required 3 to 2 majority)

We would calculate the test statistic using the formula:

z = ( p' - p) / \(\sqrt{(p(1-p)/n)\)

where p' is the sample proportion (74/120), p is the population proportion (0.6), and n is the sample size (120).

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It is a methodical approach to study phenomena through the analysis of numerical data. Statistics plays a crucial role in various fields like science, business, medicine, engineering, and social sciences.

In statistics, data can be classified into two categories: quantitative data and qualitative data. Quantitative data are numerical data that can be measured and analyzed statistically, while qualitative data are non-numerical data that are not measurable. Statistical methods are used to analyze data, and they involve various techniques such as hypothesis testing, regression analysis, correlation analysis, and data visualization. These techniques help to summarize data, identify patterns, and draw conclusions from the data.

The function f(x) = 2x³ - 36x² + 210x - 10 has two critical numbers. The smaller one is x= 1.616 and the larger one is x= 5.616.

The function f(x) has a critical point if f'(x) = 0. Since we need to find two critical points, we need to solve the following equation for x: f'(x) = 0f'(x) = 6x² - 72x + 210f'(x) = 6(x² - 12x + 35). Since we know that the expression x² - 12x + 35 is equal to 0 at x = 5 and x = 7, we can factor the above equation :f'(x) = 6(x - 5)(x - 7)Now, we need to find the values of x that make f'(x) = 0. That is, we need to solve the equation: 6(x - 5)(x - 7) = 0x - 5 = 0 or x - 7 = 0x = 5 or x = 7. Therefore, the critical points of the function f(x) are x = 5 and x = 7.

To determine whether a critical point is a relative maximum, a relative minimum, or a saddle point, we need to use the second derivative test. We will take the second derivative of the function f(x):f'(x) = 6x² - 72x + 210f''(x) = 12x - 72At the critical point x = 5,f''(5) = 12(5) - 72 = -12Since f''(5) is negative, the point x = 5 is a relative maximum of the function f(x). At the critical point x = 7,f''(7) = 12(7) - 72 = 36Since f''(7) is positive, the point x = 7 is a relative minimum of the function f(x).Therefore, the smaller critical number of f(x) is x = 1.616 and the larger critical number of f(x) is x = 5.616.

Cara invested $6,000 at 8.5% interest and $3,000 at 10.75% interest.

Let's solve the problem step by step.

Let's assume that Cara invested x dollars at 8.5% interest and y dollars at 10.75% interest. According to the given information, the total interest income for one year was $1,880.

We know that interest is calculated as the product of the principal amount, the interest rate, and the time period. Using this formula, we can write the equation:

0.085x + 0.1075y = 1,880 (equation 1)

The second given information states that x is $4,000 less than twice the y amount. Mathematically, we can express this as:

x = 2y - 4,000 (equation 2)

Now we have a system of two equations (equation 1 and equation 2) with two variables (x and y). We can solve this system of equations to find the values of x and y.

By substituting equation 2 into equation 1, we get:

0.085(2y - 4,000) + 0.1075y = 1,880

Simplifying the equation, we have:

0.17y - 340 + 0.1075y = 1,880

Combining like terms, we get:

0.2775y = 2,220

Dividing both sides by 0.2775, we find that y ≈ 8,000.

Substituting this value back into equation 2, we can solve for x:

x = 2(8,000) - 4,000

Simplifying, we get x ≈ 12,000.

Therefore, Cara invested $6,000 at 8.5% interest (x = $12,000 - $4,000) and $3,000 at 10.75% interest (y = $8,000).

To find the dimensions of the rectangle, let's denote the length as L and the width as W. Given the perimeter is 46 meters and the area is 130 square meters.

Let the length and width of the rectangle be l and w, respectively.
We know that the perimeter of a rectangle is given by: P = 2l + 2w
So, we can write:  2l + 2w = 46
Dividing both sides by 2, we get: l + w = 23
We also know that the area of a rectangle is given by: A = lw
So, we can write: lw = 130
We can now use the first equation to express w in terms of l: w = 23 - l
Substituting this into the second equation, we get:  l(23 - l) = 130
Expanding and simplifying, we get a quadratic equation:  -l² + 23l - 130 = 0
Solving this equation, we find that:  l = 10 or l = 13
If we use l = 10, then w = 23 - l = 13
If we use l = 13, then w = 23 - l = 10
So, the dimensions of the rectangle are:  10m x 13m or 13m x 10m
And both rectangles have the same area (130 m²) and perimeter (46m).
Since length and width are interchangeable, the dimensions of the rectangle are 10m x 13m.

BC² + (\(\frac{5}{13}\) )² = 1²

BC² + \(\frac{25}{169}\) = 1 ( subtract \(\frac{25}{169}\) from both sides )

BC² = \(\frac{169}{169}\) - \(\frac{25}{169}\) = \(\frac{144}{169}\) ( take square root of both sides )

BC = \(\sqrt{\frac{144}{169} }\) = \(\frac{12}{13}\)

Answer:

the width is 10ft, the length is 25ft, and the area is 250 sq ft

Answer:

The width = 10 ft./ The lenght = 25 ft./ The area = 250 ft.²

Step-by-step explanation:

use X as the width

so we'll get 2X+5 as the length

the perimeter = 2(length) + 2(width)

70 = 2(2X+5) + 2(X)

70 = 4x+10 + 2x

70 = 6x+10

60 = 6x

x = 10

as the beginning x is the width

so the width is 10 ft.

the lenght is 2x+5

2(10)+5 = 25

so the length is 25 ft.

The area of rectangle is width x length

so 10 x 25 = 250 ft.²
