Describe how to calculate dependency ration

Geography
1 answer:
alex41 [277]2 years ago
7 0

Answer:

You can calculate the ratio by adding together the percentage of children (aged under 15 years), and the older population (aged 65+), dividing that percentage by the working-age population (aged 15-64 years), multiplying that percentage by 100 so the ratio is expressed as the number of 'dependents' per 100 people aged

Which hominikm has cranial features that include a 1520 cc braincase , enlarge nose passage for livingi ncold climates?
earnstyle [38]

Sinus hominem has cranial features that include a 1520 cc braincase, and enlarged nose passage for living in cold climates.

There are 4 pairs of sinuses. These are the frontal, maxillary, ethmoid, and sphenoid sinuses (not shown). Blocked sinus openings block the flow of mucus and increase pressure, causing pain and inflammation.

Maxillary Sinus: The largest of the maxillary sinuses, located behind the cheekbone near the cranial features. Sphenoid Sinus: The sphenoid sinus is located in the sphenoid bone near the optic nerve and pituitary gland on the side of the skull.

What is different about the way molecules move in gases?
OleMash [197]

Answer:

Unlike solid and liquid state, molecules in gaseous state show random motion. That is the reason, gases take the shape of container and spread quickly in space. The random motion of molecules in the gaseous state is due to high kinetic energy in molecules. They have weak intermolecular interactions between them. The intermolecular space between gaseous molecules is very large. They can show all the three types of molecular motion, vibrational, rotational and translational motion. In vibrational motion, molecules move back and forth whereas in rotational motion the molecule rotates in space. In translational motion molecules move in certain directions. Molecules of solid-state are capable of vibrational motion due to strong intermolecular forces. Therefore, they show least random molecular motions. Like solids, liquids are capable of vibrational motion but at the same time they can also show rotational and translational motions due to weak intermolecular forces between molecules. Hence, liquids can show random molecular motions but less random compared to gas molecules. So we can say that random motion is related to temperatures, intermolecular forces of attractions, the kinetic energy of molecules and heat transfer.

DESPERATELY NEED HELP PLEASE LIKE PRETTY PLEASE, 10 points :)
Liula [17]

Answer:

I haven't studied this, I think, so this is off of what I think it might be, I suppose.

Explanation:

A: If it's widespread, it might be harder to govern everyone rather than if it was more compact. If it's bigger, one center of power in one part might not be able to handle monitoring the entire country as there's al lot of space, so their influence might not be felt throughout the entire country and rather more in the areas closest to it. Like how people who lived in England were seemingly more loyal to the king, but in America, which was an ocean away, more people seemingly felt and expressed their lack of connection to a ruler so far away.

B: If it's wide-spread enough, there might be different ideas of grouping based on it. If a river runs through it, for example, it could lead to a "east of the river" versus "west of the river" difference in how they identify. An example of this is in Italy where the North and South have differences between them or how in the U.S. there had been/is the idea of "The North vs. The South" or even "The North vs. The South vs. The Midwest vs. The West Coast".
