a pole that is 2.9 M tall casts a shadow that is 1.56 M long at the same time a nearby Tower casts a shadow that is 40.25 meters long how tall is the tower round your answer to the nearest meter
Answers
Answer:
h = 74.823 m
Explanation:
given data
pole tall = 2.9 M
shadow long = 1.56 M
Tower shadow = 40.25 meters
solution
we get here tower height that is h
so as per given image below
we could see two similar triangles.
Similar triangles have sides proportional
tan θ = [tex]\frac{2.9}{1.56} = \frac{h}{40.25}[/tex]
h = 74.823 m

Air pollution poses significant health and environmental threats across Europe, despite noteworthy improvements due to stringent regulations. Health impacts include respiratory and cardiovascular diseases, while ecosystems suffer from acid rain and altered precipitation patterns. Transboundary pollution and the need for ongoing mitigation efforts remain key challenges.
Explanation:
The effects of air pollution on several European countries have been profound and far-reaching. Despite substantial efforts and investments to reduce pollution levels, air pollution continues to pose a significant threat to public health, ecosystems, and climate. In Europe, the introduction of stringent air quality regulations has led to improvements in certain areas, but challenges remain, particularly from transboundary pollution that does not respect political borders.
Health Impacts in Europe
Air pollution has been linked to a wide range of health problems, including respiratory and cardiovascular diseases, decreased lung function, increased frequency of respiratory symptoms, and even premature death. The World Health Organization (WHO) recognizes air pollution as a major environmental threat to health. Moreover, air pollutants have been connected to IQ loss and impacts on learning, memory, and behavior in humans.
Ecosystem and Climate Effects
European ecosystems have not been spared from the effects of air pollution. Acid rain, resulting from sulfur and nitrogen oxides, has damaged forests and lakes, particularly in northern Europe, and contributed to the problem of acidification. Furthermore, air pollution has been linked to reduced rainfall in regions far from pollution sources, as demonstrated by the shrinkage of West Africa's Lake Chad - partially attributed to European air pollution.
Measures and Progress
Since the 1970s, European countries have enacted laws aimed at reducing air pollution, with significant investments exceeding one trillion dollars globally. These efforts have led to the restoration of some ecosystems and improvements in air quality in historically smog-prone areas. The European Union's clean air regulations have also contributed to positive environmental changes, emphasizing the importance of continuous efforts to combat air pollution.

Ishmail jogs around a track that is in the shape of a regular pentagon. One side of the pentagon is 1/4 mile long. How far does Ishmail jog if he completes 6 laps around the track?
Answers
Answer:
7.5 miles
Explanation:
Each side is 1/4 miles long,
a pentagon has 5 equal sides, therefore, total distance around the track in one lap is 1/4 x 5 = 5/4 miles
If he completes 6 laps, then total distance jogged will be 6 x 5/4 = 30/4 = 7.5 miles

Explanation:
The measure of x from the figure is 21
Circle geometryThe triangle in a semicircle is always a right angles triangle. From the figure shown, we can say that the triangle G J K is right triangle. Therefore
m<K = 90degrees
Given that m<K = 4x + 6, we will equate both angles to find the value of x as shown:
4x + 6 = 90
4x = 90 - 6
4x = 84
x = 21
Hence the measure of x from the figure is 21

Answers
Answer:
A) a separate part of a city dedicated largely to one group
Explanation:
On edge 2021.
The following definition that best describes an enclave is that a separate part of a city is dedicated largely to one group. The correct option is a.
An enclave is a territory (or a tiny portion of a larger territory) that is completely surrounded by the territory of another state or organization. Enclaves may exist within jurisdictional seas as well.
Enclave is a term that is frequently misused to refer to a territory that is only partially surrounded by another state. Both Vatican City and San Marino, which are enclaved by Italy, and Lesotho, which is enclaved by South Africa, are fully enclaved sovereign nations.
Therefore it can be said that the following definition that best describes an enclave is that a separate part of a city is dedicated largely to one group.
Thus, the correct option is a.

Pittsburgh was once a defense of site because of its location but it later became in urban metroplex. Which of these is the best explanation of what my happen to change the situation of the settlement
Answers
Pittsburgh evolved from a defensible site to an urban metroplex due to industrial growth spurred by the steel industry, changes in transportation and production methods with the advent of the steam engine, and socio-economic dynamics including 'white flight' and suburbanization.
Explanation:Pittsburgh's transformation from a defensible site to an urban metroplex is tied to the evolution of American cities and their changing roles in response to industrial and economic developments. Initially, cities like Pittsburgh were compact and served defensive purposes due to their strategic locations. For instance, Pittsburgh is located at a confluence site where the Allegheny and Monongahela rivers merge to form the Ohio River, providing a natural defense advantage and creating opportunities for river-borne trade.
However, with the Industrial Revolution and the advent of the steam engine, the need for cities to be limited by natural power sources such as rivers declined. Factories could be built near urban centers like Pittsburgh, which led to rapid urban growth. The city's industry, particularly steel production, thrived due to the availability of iron and coal in the region. This growth attracted a large workforce and required a city infrastructure that supported a much larger population, leading to urban expansion.
The concept of 'white flight' and suburbanization also contributed to changing the dynamics of Pittsburgh and similar cities. As minority populations and the impoverished migrated to cities for opportunities, white and middle-class residents often moved to the suburbs, taking with them substantial amounts of tax revenue. This exacerbated the financial strain on urban areas and shifted wealth to the suburbs, creating a stark contrast between the city and suburban environments.
