7. How old is a mineral that contains
25 percent U-235?

Answer:

It took climate change, fertile river valleys, domestication of crops and animals so that the hunter-gatherers became sedentary farmers.

Explanation:

Initially, all humans were hunter-gatherers. This was due to multiple reasons, with one the biggest one probably being the climate which was not enabling good conditions for the hunter-gatherers to transform their lifestyle. All other conditions needed were stopped because of the climate conditions, so humans had to do what they could to survive in those conditions.

About 10 years ago though the bad climate conditions ended, or rather the Ice Age ended. This resulted in a much warmer climate, which in turn created much more water bodies like rivers and lakes, much more vegetation, and they contributed to the creation of much more fertile soil.

With these conditions in place, the humans quickly saw that there is huge potential in some plants and animals, so they started to farm them, select the ones with the best characteristics, and gradually producing enough food for themselves. With the food problem solved, humans didn't have the need to wonder around all the time, so they started abandoning the hunter-gatherer lifestyle and started settling in one place.

Answer:

The United States Constitution refers to the powers of the President and the powers of the US Congress. Regarding foreign policy, the President of the United States is the chief diplomat of the United States. He can sign international treaties that later can be ratified by Congress. On the other hand, Congress discusses and comments those treaties and trade agreements and sent it to the President to sign them. Another important function of Congress regarding foreign policy is that only the US Congress can declare war to other nations.

Answer:

b

Explanation:

Answer:

(a) check the explanation

(b) the possible values of b is 6i or -29

Explanation:

Given function;

16x⁴ - 4x³– 4b²x² + 7bx + 18

(a)

factor of the given function = 2x + b

then, 2x + b = 0

x = -b/2

substitute the value of b into the given function;

16x⁴ - 4x³– 4b²x² + 7bx + 18

[tex]16(\frac{-b}{2} )^4 -4(\frac{-b}{2})^3-4b^2(\frac{-b}{2})^2 +7b(\frac{-b}{2})+18=0\\\\b^4+\frac{b^3}{2} -b^4-\frac{7b^2}{2} +18=0\\\\\frac{b^3}{2} -\frac{7b^2}{2} +18=0\\\\multiply\ through \ by \ "2"\\\\b^3-7b^2+36 =0 \ (shown)[/tex]

(b)

b³ - 7b² + 36 = 0

b²(b - 7) + 36 = 0

b²(b - 7) = -36

b² = -36                or b - 7 = -36

b = √(-36)             or  b = -36 + 7

b = √(-1) x √(36)   or  b = -29

b = 6i       or   -29              

Answer:

UH WHERE ARE THE EXAMPLES!?!?!!?

Explanation:

Answer: answer is B on edge

Explanation:

Answer:

Mountain ranges often appear on the edges of continents.

Fossils of the same animals appear on the edges of continents.

Explanation:

The theory of continental drift suggests that Earth's crust is cracked into numerous tectonic plates that move across the globe in a different direction. The reason for this is the convection currents from the mantle which create huge pressure on the crust managed to crack it in the first place and push it in a certain direction.

There are numerous pieces of evidence that support this theory and two of those are the location of the newer mountain ranges and the fossils. The mountain ranges form at the edges of continents, or rather where tectonic plates collide, thus the crust lifts up because one of the plates subducts and gradually creates mountain ranges. Every organism is unique and it adapted to particular living conditions and there is pretty much zero chance that the same organism can exist in totally different environments and in places that have no connection whatsoever. Finding fossils of the same species on several different continents that are thousands of km away from each other proves that ones they were merged and had the same living conditions.

Answer:

B. Mountain ranges often appear on the edges of continents.

C. Fossils of the same animals appear on different continents.

Explanation:

I did the assignment on Edg.2020.

Answer:

P=43

Explanation:

As, the both angles are linear, so if we add them, we will get 180°.

So, p+7 + 3p+1 = 4p + 8

So, 4p + 8 = 180

So, 4p = 180 - 8

4p = 172

P= 172/4

P = 43

So p+7 + 3p+7 = 43 + 7 + ( 3x43 + 1) = 180

Therefore, p = 43

it is nontoxic

it is lightweight

Explanation:

The pure titanium can be defined as a white lustrous metal. It exhibit low density thus, it is light in weight. It is resistant to corrosion thus it is durable. It is obtained in the form of minerals like leucoxene, rutile, and other forms. Titanium is not a toxic metal and the human body can tolerate the large doses of the titanium.  Exceptionally, the titanium dioxide exhibit very low level of toxicity.

his mothers tongue probably belonged to the Spanish language group

A man lives in Europe. His mother tongue probably belongs to the Indo-European language family.

The Indo-European languages refer to a language family native to the overwhelming majority of Europe, the Iranian plateau, and the northern Indian subcontinent. Some European languages of this family, English, French, Portuguese, Russian, Dutch, and Spanish, have expanded through colonialism in the modern period and are now spoken across several continents.

The Indo-European family is divided into several branches or sub-families, of which there are eight groups with languages still alive today: Albanian, Armenian, Balto-Slavic, Celtic, Germanic, Hellenic, Indo-Iranian, and Italic; and another nine subdivisions that are now extinct. Today, the individual Indo-European languages with the most native speakers are English, Hindi–Urdu, Spanish, Bengali, French, Russian, Portuguese, German, and Punjabi, each with over 100 million native speakers; many others are small and in danger of extinction.

The various subgroups of the Indo-European language family include ten major branches.

The correct answer is B. A supply of inexpensive labor

Explanation:

Manufacturing most products in Mexico is cheaper than doing this in the U.S. The main reason for this is that in Mexico labor (workers needed for production) is cheaper than in the U.S. This factor is related to the fact the currency in Mexico has less value than the currency in the U.S. and the social, economic, cultural conditions are different. Besides this, production can be easily controlled in Mexico because this borders the U.S. According to this, one factor that makes some American companies locate factories in Mexico is the supply of inexpensive labor.

Following are the solution to the given points:

Explanation:

15-minute charts display a latitude and longitude zone of 15 minutes. It was a collection of graphs designed to chart the whole US area on the very same scale.

In point 1:

In the United States, the American Government raises the worth through North to South (from the right of the map towards the left).

Therefore, the left portion's latitude value: =76°00’00”+0°15’00”=76°15’00”

In point 2:

That value of altitude increases to the top of the map.

That latitude meaning at bottom of a map:

=43°15’00” - 0°15’00”=43°00’00”

In point 3:

In this floor as per the scale from 1 inch mostly on map.

Thus 1"=24000"=2000 ft

In point 4:

The map depicts 24000 ft at the floor in conjunction with the scale 1 foot. Consequently, 1 foot=24000ft=7,3152 km
