We use J to represent Juile's original height, giving:

J + 19 = 65

This equation represents the relationship between Juile's original height and her height after the increase.

The sentence "Juile's height increased by 19 is 65" can be translated into an equation by breaking it down into two parts:

Juile's height increased by 19: This means that you can take Juile's original height and add 19 to it to get the new height after the increase.

The new height after the increase is 65: This means that the new height after the increase is equal to 65.

Combining these two parts, we get:

Juile's original height + 19 = 65

We use J to represent Juile's original height, giving:

J + 19 = 65

This equation represents the relationship between Juile's original height and her height after the increase.

Step-by-step explanation:

To estimate the number of students out of the next 10 who will support Julian, we can use the proportion of students who have supported Julian so far.

The total number of students who have been surveyed is:

15 + 9 + 16 + 10 = 50

Out of these 50 students, 15 have supported Julian. Therefore, the proportion of students who have supported Julian so far is:

15/50 = 0.3

To estimate how many of the next 10 students surveyed will support Julian, we can multiply the proportion of students who have supported Julian so far by 10:

0.3 x 10 = 3

Therefore, we can estimate that out of the next 10 students surveyed, about 3 will support Julian.

Answer:

≈ 44°

The correct answer is the second one

Step-by-step explanation:

Use trigonometry:

\( \cos(x°) = \frac{15}{21} \)

Use the reverse function (SHIFT, cos) on your calculator to find x:

\(x≈44°\)

Check the picture below.

\(\cos(x )=\cfrac{\stackrel{adjacent}{15}}{\underset{hypotenuse}{21}}\implies \cos(x)=\cfrac{5}{7}\implies x=\cos^{-1}\left( \cfrac{5}{7} \right)\implies x\approx 44^o\)

Lilly needs 686 dark power crystals to raise 6174 zombies.

To solve this problem, we need to determine how many dark power crystals are needed to raise a specific number of zombies. We know that each crystal can raise 9 zombies. So, to determine the number of crystals needed to raise a given number of zombies, we simply divide that number by 9.

In this case, we want to know how many crystals Lilly needs to raise 6174 zombies. So we divide 6174 by 9

= 6174 / 9

Divide the numbers

= 686

This means that Lilly needs 686 dark power crystals to raise 6174 zombie

What is Law of sines ?

The Law of Sines is a trigonometric formula that relates the side lengths of a triangle to the sine of its angles. It states that in any triangle ABC:

a / sin(A) = b / sin(B) = c / sin(C)

where a, b, and c are the side lengths of the triangle, and A, B, and C are the opposite angles.

This formula can be used to solve for the unknown sides or angles of a triangle when given enough information about the other sides and angles. The Law of Sines is especially useful when dealing with triangles that are not right triangles, or when only a few side lengths and angles are known.

According to the question:

We can solve this problem by using the Law of Sines and the fact that the sum of the angles in a triangle is 180 degrees.

First, we can find the measure of angle A in triangle ABC:

A = 180 - 48 - 48 = 84 degrees

Next, we can use the Law of Sines to find the length of side AC:

sin(84) / 50 = sin(48) / AC

AC = sin(84) * 50 / sin(48) ≈ 64.4

Now, we can use the fact that the sum of the angles in triangle AQS is 180 degrees to find the measure of angle QAS:

QAS = 180 - 20 - 90 = 70 degrees

Finally, we can use the Law of Sines again to find the length of RS:

sin(70) / RS = sin(48) / AC

RS = sin(70) * AC / sin(48) ≈ 72.6

Therefore, the length of RS is approximately 73 meters (to the nearest meter).

According to the NIOSH guidelines, a lifting index (LI) value below 1 is considered acceptable, indicating a low risk of developing work-related musculoskeletal disorders.

In the given scenario, the LI values for the two lifts are calculated as follows:

For the first lift:

LI = 20/12.52 = 1.60

For the second lift:

LI = 20/29.56 = 0.68

Based on these calculations, the second lift with an LI value of 0.68 is acceptable according to the NIOSH guidelines since it is below the threshold of 1.

To reduce the LI value below 1, several changes can be made to the layout and lifting procedure:

Reduce the weight of the castings: If it is possible to use lighter castings, it would decrease the load weight, resulting in a lower LI value.

Modify the work area height: Adjusting the work area height to a lower level, closer to the inspector's body, would decrease the vertical distance of the lift and consequently lower the LI value.

Optimize the horizontal distance: If feasible, reposition the work area closer to the inspector's body to reduce the horizontal distance of the lift, which would contribute to a lower LI value.

By implementing these changes, the new LI values can be calculated using the provided formulas to ensure compliance with the company policy of maintaining an LI value below 1.

The detail that adds tension to the rising action of the story is when Mother Wolf tells Mowgli that some day he will have to kill Shere Khan.

This statement introduces a sense of conflict and foreshadows a significant challenge that Mowgli must face in the future. The idea of Mowgli, a young boy raised by wolves, confronting and defeating the powerful and dangerous Shere Khan adds suspense to the story, as readers anticipate the eventual showdown between these two characters.

Other details, such as Mowgli growing stronger and learning life lessons, or Mowgli forgetting his mother's advice, are relevant to his character development, but do not contribute as directly to the story's tension. Similarly, Mowgli considering himself a wolf and lacking the ability to speak like a human reflects his unique upbringing, but does not add tension in the same way as the impending confrontation with Shere Khan.

In conclusion, Mother Wolf's warning about Mowgli's future encounter with Shere Khan adds tension to the rising action of the story, as it sets up an exciting and challenging conflict for the protagonist to face, capturing the reader's interest and anticipation.

The GINI coefficient is a statistical measure used to quantify income inequality within a population. It ranges from 0 to 1, where 0 represents perfect equality and 1 represents extreme inequality.

Here are the pros and cons of the GINI coefficient:

Pros:
1. Simplicity: The GINI coefficient is easy to understand and calculate, making it a widely used measure of inequality.
2. Comparative Analysis: It allows for comparison of inequality levels across different countries or regions, providing insights into the distribution of income and wealth.
3. Sensitivity to Changes: The GINI coefficient is sensitive to changes in the income distribution, making it useful for tracking trends over time.

Cons:
1. Limited Scope: The GINI coefficient does not capture all aspects of inequality, such as differences in education or health outcomes.
2. Insensitive to Middle Class Changes: It may not reflect changes in the middle-income groups, as it focuses on the extremes of the income distribution.
3. Data Limitations: The accuracy of the GINI coefficient depends on the quality and availability of data, which can vary across countries and time periods.

Comparing GINI with percentile ratio measures of inequality:
GINI coefficient provides an overall measure of inequality, while percentile ratio measures focus on specific income percentiles (e.g., top 10% vs. bottom 10%). Percentile ratios give more detailed information about the income distribution at specific points, but they may not capture the overall inequality picture. Both measures have their strengths and weaknesses and can be used in conjunction to gain a comprehensive understanding of income inequality.

Answer:

The actual distance between cities = 345 miles

Step-by-step explanation:

Given that:

Scale on map is

1/2 inch = 30 miles

0.5 inch = 30 miles

Distance between two cities on map = \(5\frac{3}{4}\) = \(\frac{23}{4}\) = 5.75 inches

Actual distance = x

As the relationship is proportional

0.5 : 30 :: 5.75 : x

Product of mean = Product of extreme

30*5.75 = 0.5x

172.5 = 0.5x

0.5x = 172.5

Dividing both sides by 0.5

\(\frac{0.5x}{0.5}=\frac{172.5}{0.5}\\x=345\)

Hence,

The actual distance between cities = 345 miles
