Which expressions can be used to find the coordinates of the midpoint of PQ with endpoints P(3, –1) and Q(–7, –6)? Select three options.
can be used to find the x-coordinate of the point.
can be used to find the y-coordinate of the point.
(–7 – 3) + 3 can be used to find the x-coordinate of the point.
(–6 – 1) – 1 can be used to find the y-coordinate of the point.
– 1 can be used to find the y-coordinate of the point.
Answer:
To determine the midpoint of a line segment with the given endpoints, one should determine the averages of the coordinates of the points.
x-coordinate: (3 + -7) / 2 = -2
y-coordinate: (-1 + -6) /2 = -7/2
Hence, the coordinates of the midpoint of the line segment are (-2, -7/2).

(i) how does the spacing of the contour lines show the difference between gentle and steep slopes? [ select ]
Closely spaced contours represent steep slopes while widely spaced contours represent gentle slope.
Contour lines are drawn to indicate locations of the same elevation. Contours and their shapes represent the elevation and slope or slope of a terrain. Theses are lines drawn on topographic maps that indicate the elevation of the ground. Contour interval is the vertical distance or elevation difference between contour lines.
As the number associated with a particular contour line increases, so does the elevation of the terrain. Elevation decreases as the number associated with the contour decreases. As the contour approaches a stream, ravine, or drainage area, the contour rotates upstream.

Why do you think temperatures are higher at the surface than at the middle and upper portions of the troposphere?.
Temperatures are higher at the surface than at the middle and upper portions of the troposphere because cooling air expands.
The warmest temperatures in the troposphere are often found at the earth's surface because the sun heats the atmosphere predominantly from the surface and because the air cools as it ascends. The surface is heated by the sun, and this energy is then distributed upward into the troposphere by mixing air. Since the Earth's surface is the primary source of heat, temperatures will be hottest at the surface and decrease away from the surface. The troposphere's average temperature profile will indicate a temperature decrease with height.
As temperature decreases with height in the troposphere, it may be easier for air to rise vertically because cold air is less stable than warm air. As air rises, it cools exponentially. This is another reason why the temperature is higher at the surface. For air to rise to higher altitudes, it must be cooler. Air density and pressure are highest at the surface. When air increases, it extends because the pressure is descending. The air cools by expanding. Because the Sun heats the troposphere primarily from the surface and because the air cools as it rises, the average warmest temperature in the troposphere is at Earth's surface.

A country in stage 3 would be the most likely to have the highest percentage of women *without* children.
In the third stage of the demographic transition model (DTM), mortality is low and fertility is declining. This is usually the result of better economic conditions, higher levels of women's status and education, and greater access to contraceptives. Overall population growth is slowing in stage 3 countries due to low birth and death rates.
Education has been consistently associated with delaying women's fertility, giving women opportunities outside the home, and increasing knowledge about women's bodies and health. All of these reduce family size and ultimately lead to lower birth rates.

What we can do is talk about some things that all living things on Earth share: They're carbon-based; they require water; they use energy. Perhaps most important for survival, they can grow or reproduce in some way.
What environmental factors on the early Earth permitted life to exist?Early Hadean Earth's primary source of nutrients would have been the surface rocks, which were abundant in rarer elements like potassium and uranium as well as iron and phosphorus. Another important prerequisite is an abundance of gases that comprise substances like ammonia and methane.
The earth was extremely heated for what three reasons?In the deep earth, heat is primarily produced by three different processes: (1) heat that was present during the planet's formation and accretion and has not yet been lost; (2) frictional heating brought on by the planet's denser core material sinking to its center; and (3) heat produced by the radioactive decay of elements.
What circumstances existed on the early Earth?The original atmosphere probably had little oxygen and was heavy with water vapor as well as gases produced during volcanic eruptions such nitrogen and its oxides, carbon dioxide, methane, ammonia, and hydrogen. Oceans formed as Earth cooled, and a significant amount of hydrogen escaped into space.
What are the core's inner three facts?Inner Core The inner core is a hot, heavy, and mostly iron ball. It has a 1,220 kilometer circumference (758 miles). About 5,200° Celsius (9,392° F) is the temperature inside the core. Nearly 3.6 million atmospheres are present (atm).

Which planet in the solar system takes the least time to revolve around the sun?.
Mercury in the solar system takes the least time to revolve around the sun.
Mercury takes 88 Earth days to complete one orbit around the sun. That is, a year for Mercury is 88 Earth days and therefore, the shortest of all the planets. The reason behind is Mercury being the closest planet to the Sun.
The closer a planet is to the Sun, the faster it travels. Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.Mercury is the smallest planet in our solar system.

One way to mitigate flooding is to build floodways, which are areas that are intended to flood and as such are not zoned for buildings.
A floodway is described as a man-made channel that is designed to divert water from a river or other watercourse and the nearby land regions during flood events without raising the water surface elevation overall above a certain height.
They can resist such circumstances while being built to be buried in water. By generating a diversity of habitats for fish and other species, floodways benefit nature. Additionally, floodplains are crucial for groundwater recharging, water quality protection, and storage and conveyance of water.

It is a hypothetical line that is situated halfway between the North and South poles at latitude 0 degrees. The parallel (circle of latitude) at which latitude is defined to be 0° is known as the equator of a spinning spheroid (such as a planet) in spatial (3D) geometry, which is used in astronomy. It is a hypothetical line on the spheroid that divides it into the northern and southern hemispheres and is located equidistant from its poles.Why is the equator so warm?Sunlight touches the Earth most directly at the Equator.
