Congruence between two polygons can be established if their corresponding sides and angles are equal.
What is Congruence?Generally, Congruence is a term used in geometry to describe the relationship between two geometric figures that have the same shape and size. Two figures are considered congruent if they have the same size and shape, which means that all of their corresponding sides and angles are equal.
When two figures are congruent, they can be superimposed on each other so that all their corresponding parts coincide perfectly. Congruent figures are denoted by the symbol ≅. For example, if two triangles are congruent, we would write them as ΔABC ≅ ΔDEF.
Congruence is an important concept in geometry because it allows us to prove that two figures are identical without measuring every side and angle. Instead, we can use the properties of congruence to show that corresponding parts of the figures are equal, which is a powerful tool for solving geometry problems.

Which factors have put pressure on Cairo’s water supply?
a. environmental conservation efforts
b. population growth and pollution
c. political corruption and bribery
d. high costs of dam repairs
Population expansion and pollution are the main causes of pressure on Cairo's water supply. Over time, the population of the city has grown steadily, increasing the need on water supplies.
Cairo's water supply has been under pressure mostly as a result of population expansion and pollution. As the city has expanded, so has the need for water, which has resulted in resource misuse and depletion. Water supplies have also been poisoned and rendered unfit for consumption due to pollution from industrial, agricultural, and sewage that has not been treated. Political bribery and corruption have slowed the development of sustainable water management systems, and there have been few environmental conservation measures. While infrastructure maintenance and upgrades are required to provide a dependable water supply, high costs of dam repairs have also been an issue. In general, overcoming these obstacles will call for a concerted effort from the government, business, and civil society to safeguard and manage Cairo's water resources for the future.

An oil company purchased an option on land in Alaska. Preliminary geologic studies assigned the following prior probabilities. P(High- quality oil) = 0.3 P(medium - quality oil)=0.4 P (no oil)= 0.3 a. What is the probability of finding oil (to 1 decimal)? b. After feet of drilling on the first well, a soil test is taken. The probabilities of finding the particular type of soil identified by the test are given below. P(Soil /High- quality oil) = 0.4 P(Soil/medium - quality oil)=0.4 P (Soil/no oil)= 0.2 Given the soil found in the test, use Bayes' theorem to compute the following revised probabilities (to 4 decimals). P(Soil /High- quality oil) = ? P(Soil/medium - quality oil)= ? P (Soil/no oil)= ? C. What is the new probability of finding oil (to 4 decimals)?
a. The probability of finding oil (to 1 decimal) is 0.7
b. Using Bayes' theorem to compute the following revised probabilities (to 4 decimals). P(Soil /High- quality oil) = 0.3008
P(Soil/medium - quality oil)= 0.4018
P (Soil/no oil)= 0.0974
C. The new probability of finding oil (to 4 decimals) is 0.6878
How did we get the values?a. The probability of finding oil is the sum of the probabilities of finding high-quality and medium-quality oil, which is:
P(Oil) = P(High-quality oil) + P(Medium-quality oil) = 0.3 + 0.4 = 0.7
b. Bayes' theorem states that the revised probability of an event A, given new evidence B, is equal to the prior probability of A multiplied by the conditional probability of B given A, divided by the prior probability of B. In this case, we want to compute the revised probabilities of finding the particular type of soil identified by the test, given the three different oil quality scenarios:
P(Soil / High-quality oil) = P(High-quality oil / Soil) * P(Soil) / P(High-quality oil)
= (P(Soil / High-quality oil) * P(High-quality oil)) / P(Soil)
= (0.4 * 0.3) / (0.40.3 + 0.40.4 + 0.2*0.3)
= 0.3008 (rounded to 4 decimals)
P(Soil / Medium-quality oil) = P(Medium-quality oil / Soil) * P(Soil) / P(Medium-quality oil)
= (P(Soil / Medium-quality oil) * P(Medium-quality oil)) / P(Soil)
= (0.4 * 0.4) / (0.40.3 + 0.40.4 + 0.2*0.3)
= 0.4018 (rounded to 4 decimals)
P(Soil / No oil) = P(No oil / Soil) * P(Soil) / P(No oil)
= (P(Soil / No oil) * P(No oil)) / P(Soil)
= (0.2 * 0.3) / (0.40.3 + 0.40.4 + 0.2*0.3)
= 0.0974 (rounded to 4 decimals)
c. The new probability of finding oil, given the soil test, is the sum of the probabilities of finding high-quality and medium-quality oil, weighted by their revised probabilities based on the soil test:
P(Oil / Soil) = P(High-quality oil / Soil) + P(Medium-quality oil / Soil)
= P(Soil / High-quality oil) * P(High-quality oil) / P(Soil) + P(Soil / Medium-quality oil) * P(Medium-quality oil) / P(Soil)
= (0.4 * 0.3 / (0.40.3 + 0.40.4 + 0.20.3)) + (0.4 * 0.4 / (0.40.3 + 0.40.4 + 0.20.3))

The concept of a global flood and its timing is a matter of debate among scholars and religious traditions, and not all people hold the belief that such an event occurred.
However, assuming that the question refers to the Biblical narrative of the Great Flood, there is no scientific evidence to support the idea that people began exploring the ocean soon after the flood. The flood narrative describes a catastrophic event that supposedly took place in the ancient Near East, thousands of years ago, and it is not connected to the historical evidence for ocean exploration.

slab pull refers to . multiple choice question. subducting lithosphere transform boundaries of lithospheric plates divergent boundaries of lithospheric plates subducting mantle
Slab pull is a geophysical phenomenon whereby the cooling and subsequent densification of a subducting tectonic plate impose downward pressure along the rest of the plate.
What is slab pull?The process that occurs along a subduction zone when a dense oceanic plate falls beneath a buoyant plate, bringing the remaining plates behind it. Subduction is the process through which a tectonic plate descends into the mantle. When an oceanic plate subducts into the underlying mantle, slab pull happens. Subduction zones are just one form of convergent border where two tectonic plates are clashing. A crustal plate cools and gets denser as it advances away from an oceanic ridge. As a result, it subducts into a zone beneath the continental crust. The rest of the plate is also dragged downward by the weight of the sinking, cooling plate due to a strong pulling action.To learn more about slab pull, refer to:

Which geologic process is needed for igneous rock to turn into metamorphic rock? answer choices
compaction
cooling
heating under pressure
melting
weathering
Heating under pressure geologic process is needed for igneous rock to turn into metamorphic rock.
The process of metamorphism involves the application of heat and pressure on pre-existing rocks to produce a new type of rock that has different physical and chemical properties than the original rock. Heat and pressure cause the minerals in the rock to recrystallize and form new minerals, thereby changing the composition of the rock. This process is called metamorphism and is a natural geologic process that occurs in the Earth's crust.
Metamorphic rocks are formed when rocks are exposed to extremely high temperatures and pressures. The types of metamorphic rocks formed depend on the type of pre-existing rocks as well as the temperatures and pressures applied.

What makes up molten magma?Magma is a molten and semi-molten rock mixture found beneath the Earth's surface. This mixture is typically composed of four components: a hot liquid base known as the melt, minerals crystallized by the melt, solid rocks incorporated into the melt from the surrounding confines, and dissolved gases.
Magma is formed when mantle rocks partially melt. As the rocks ascend (or have water added to them), they begin to melt slightly. These small blobs of melt migrate upward and coalesce into larger volumes that continue to rise. They could congregate in a magma chamber or just come straight up.

Explanation:
True/False? Surface oceanic circulation results most directly in the
Distribution of heat from tropical to temperate and polar regions
True. Surface oceanic circulation is driven by the combination of wind, the Coriolis effect, and differences in water temperature and salinity.
What is meant by Surface oceanic circulation?Surface oceanic circulation, also known as the ocean conveyor belt or thermohaline circulation, is a large-scale circulation system that distributes heat and nutrients around the globe. The circulation system is driven by winds, which set the ocean currents in motion, and the Coriolis effect, which deflects the currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Additionally, the differences in water temperature and salinity, caused by factors such as evaporation, precipitation, and melting of ice, also contribute to the oceanic circulation. This system has a significant impact on the Earth's climate by regulating the distribution of heat and nutrients in the ocean, influencing weather patterns, and affecting marine life. The redistribution of heat by the oceanic circulation helps maintain a relatively stable climate and prevents extreme temperature variations in different regions of the world.

what is the most common wind direction 15° south of earth’s equator
The most common wind direction 15° south of Earth's equator is generally from the east, also known as the trade winds. The trade winds are a prevailing pattern of easterly surface winds that flow from the subtropical high-pressure zone towards the equatorial low-pressure zone.
At 15° south of the equator, the trade winds are typically strongest and most consistent, with an average wind speed of around 15-20 knots (17-23 mph).
The trade winds play an important role in global weather patterns, ocean currents, and the distribution of heat around the planet, and have been used by sailors for centuries to navigate the world's oceans.
The trade winds are named as such because they were historically used by traders and sailors to travel from Europe and Africa to the Americas. They were first discovered by the Portuguese navigator Vasco da Gama in the late 15th century, and were later used by Christopher Columbus and other explorers to make their voyages across the Atlantic Ocean.
The trade winds are caused by the differential heating of the Earth's surface, with warm air rising at the equator and cooler air sinking at the poles. This creates a global pattern of air circulation, with air flowing from the high-pressure zones at the poles towards the low-pressure zones at the equator.
