2. Which part of the hydrologic cycle (water cycle) would be responsible for the warm mois
air over the Gulf of Mexico causing precipitation over the state of Ohio?

Answers

Answer:

Condensation

Explanation:

The water cycle (also known as the hydrologic cycle) is the name given to the continuous movement of water on Earth. Our planet has many reservoirs of water, such as glaciers, lakes, rivers, and clouds, and water moves constantly between these different reservoirs. Several processes allow for this movement, including evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow.

The process of condensation occurs when water changes from a gas phase into a liquid phase. This is often expressed in the form of rain. Therefore, this is the process that is responsible for the warm moist air over the Gulf of Mexico causing precipitation over the state of Ohio.

The vertices of △XYZ are X(4, 5), Y(4, 13), and Z(8, 9). Find an equation of the circle circumscribed about △XYZ.


An equation is ???


NEEED HELPPP PLEASEEE

Answers

Answer:

The equation of the circle is (x - 4)² + (y - 9)² = 4²

Explanation:

The center radius form of the equation of the circle is (x - h)² + (y - k)² = r²

Therefore, given the coordinates of the vertices of the inscribed triangle, we have points on the circumference includes;

X(4, 5), Y(4, 13), Z(8, 9)

Hence, we have;

(4 - h)² + (5 - k)² = r² = h²- 8·h - 10·k + k² + 41..........(1)

(4 - h)² + (13 - k)² = r² = h² - 8·h + k² - 26·k +185.....(2)

(8 - h)² + (9 - k)² = r² = h² - 16·h -18·k + k² +145.........(3)

Subtracting equation (1) from (2), we have;

-(16·k -144) = 0

∴ 16 k = 144

k = 9

Subtracting equation (1) from (3), we have;

-(8·h + 8·k - 104) = 0

Which gives;

8·h + 8·k - 104 = 0, where k = 9 gives

8·h + 8×9 - 104 = 0

8·h - 32 = 0

h = 32/8 = 4

Plugging in the values of h and k in equation (3), we have;

(8 - 4)² + (9 - 9)² = r²

4² = r²

∴ r = 4

The equation of the circle is (x - 4)² + (y - 9)² = 4².

The most important natural resource in the Middle East is __________. A. coal B. gold C. iron D. oil

Answers

The correct answer is D. Oil.

Explanation

Oil is a natural resource that is produced as a result of physical-chemical processes that occur in the lower layers of the earth, where the fossils of ancient organisms were trapped, after years those fossils are exposed to the high pressures of superior layers of the crust, producing oil. This natural resource can be extracted by humans through machines and is used for the production of gasoline and other products. The Middle East is a region known for having the largest number of oil sources, which has caused confrontations between countries, foreign intervention, and great profits for these countries, a sample of these gains are the large buildings and eccentricities that are seen in the Arab Emirates like the city of Dubai. So, the correct answer is D. Oil

Lucinda has 9 ounces of flour. A batch of cupcakes requires 1/3 ounce of flour. A batch of muffins requires 1/4 ounce of flour. How many more batches of muffins than batches of cupcakes can Lucinda make with her flour?

Answers

Answer:

9 more muffins

Explanation:

Lucinda has 9 ounces of flour.

To make a cupcake she requires 1/3 ounce of flour, therefore the number of cupcakes she can make from 9 ounces of flour can be given by:

(1/3)x = 9 where x is the number of cupcakes.

Therefore, x = 9 × 3 = 27 cupcakes

To make a muffin she requires 1/4 ounce of flour, therefore the number of muffins she can make from 9 ounces of flour can be given by:

(1/4)y = 9 where y is the number of muffins.

Therefore, y = 9 × 4 = 36 muffins

The number of more muffins she can make more than cupcakes from her flour = 36 - 27 = 9 more muffins

Answer:

15more batches

Explanation:

9 divided by 1/3 = 27

9 divided by 3/4 = 12

27- 12 = 15

Answers

The correct answer is B. Elevation

Explanation

Altitude or elevation is the name given to the number of meters above the level of the sea at which a point is located. Altitude is a factor that directly affects the temperature of a certain point on the planet, for example, in tropical areas where humidity is highest, the temperature decreases 1° Celcius for every 180 meters of elevation. While in subtropical or dry areas the temperature decreases 0.5° Celcius for every 180 meters of elevation. Therefore, in the coastal areas where it is at sea level, the temperature is usually warmer, while in the tops of the mountains we find snowfalls with low temperatures. According to the above, the correct answer is B. elevation
