Answer:
let two numbers be x & y
x-y=3 ..........(1)
by question
xy=70
x=70/y..... ..............(2)
Explanation:
putting the value of x in equation 1,we get
70/y-y=3
(70-y²)/y=3
70-y²=3×y
70-y²=3y
0=y²+3y-70
y²+10y-7y-70=0
y(y+10)-7(y+10)=0
(y+10)(y-7)=0
either
y=-10(rejected)
or
y=7
:.y=7
putting the value of x in equation 1
x-7= 3
x=3+7=10
therefore required no is 3 and10

. Explain the distribution (this includes DENSITY & CONCENTRATION) of the world's population. Be sure to identify specific regions, not just continents as a whole. :) for world Geography
Answer:
The concepts of population distribution and density are so closely related to ... In most countries of the world the geographic distribution of the population is not even with varying degrees of concentration of population giving rise to varying densities in the ... mainly responsible for discouraging inhabitation in certain areas.We can define population distribution as the pattern of where people live. Population distribution is
perhaps the most essential of all geographic expressions, because the ways in which people have
organized themselves in space at any given time represent the sum of all of the advances they have
made to their overall geographical area. Population distribution can also describe how people are
arranged according to different variables such as age, sex, religion, or race.
World population distribution is uneven. Sparsely-populated regions are usually harsh places to live.
These places usually have hostile environments; some examples are the Sahara Desert or Antarctica.
Densely populated areas have more habitable environments – for instance, most of Europe.
When we talk about population and its characteristics, it is easy to confuse similar concepts. For
example, you may confuse population distribution with population density. Population density is the number of people per unit of land area, whereas population distribution is the pattern of where the
people live. When you study population distribution and density at the global level, they are both
usually depicted graphically by how many people live in a square mile. When you study population at
the local or regional level, you can get a better view of patterns in where people live and how they’re
distributed. There are three basic patterns of population distribution: they can equally-spaced apart
(uniform dispersion), randomly spread out with no predictable pattern (random dispersion), or bunched
in groups (clumped dispersion).
An example of population distribution is the fact that China’s natural physical conditions resulted in
uneven population distribution. There is a huge contrast in the number of people living in eastern China
compared to the distribution in the western part of the country.
An example of population density would be that the in 2016, the population density of the United States
was 91.5 people per square mile of land area.
Explanation:
What are some examples of..
a) institutional land use
b) industrial land use
c) commercial land use
Answer:
A: Some examples of institutional land use are schools, government office buildings, and art galleries that occupy land.
B: Some examples of industrial land use are pieces of lands that manafacturing buildings usually occupy, so a plant that could cuase some sort of pollution would be an example.
C: Some examples of commercial land use would be someone advertising their business or a house on sale that is being broadcasted.

Which of the following is NOT a contributing factor to Africa's rapid rate of urbanization?
Better lifestyle
Education
Jobs
Negative population growth
Rapid population growth
Negative population growth is the factor that is NOT a contributing factor to Africa's rapid rate of urbanization. Hence, option D is correct.
What factors that affected the urbanization in Africa ?Urbanization refers to the process by which people move from rural areas to cities or urban areas. In Africa, there has been a rapid rate of urbanization in recent years, and there are several contributing factors to this trend. These factors include:
Better lifestyle: Many people are attracted to the perceived higher standard of living and greater economic opportunities in urban areas.
Education: Urban areas often have better access to education and other services than rural areas, which can also be a draw for migrants.
Jobs: Urban areas typically offer more job opportunities, which can be a major factor in attracting people to cities.
Rapid population growth: The high population growth rates in many African countries can contribute to the rapid rate of urbanization, as more people move to cities in search of opportunities.
Negative population growth, on the other hand, would have the opposite effect and could slow down the rate of urbanization, as there would be fewer people looking to move to cities.
Hence, option D is correct.

What city located less than 50 miles from Boston (as the crow flies) but cannot be accessed in a 120-minute drive (hint: water contributes to the time)? https://education.maps.arcgis.com/home/webmap/viewer.html?webmap=353fb62cfabb4557865e688a4ac69678
Answer:
Provincetown
Explanation:
Provincetown is a city that is outside of the 90 to 120 minute drive, yet is close to Boston as the crow flies.
The city that is located less than 50 miles from Boston but cannot be accessed in a 120-minute drive is the city of Provincetown, Massachusetts.
> The reason why is because there is a large portion of water that divides the shore of Boston and Provincetown.
> This portion of water is known as Cape Cod Bay.
> Provincetown is at the tip of Cape Cod.
> This city is a tourist attraction at the tip of Cape Code, that belongs to Barnstable County, Massachusetts,
> That is the reason why you have to drive your car all along Highway 3 and then Highway 6 at Barnstable.
> During your trip from Boston, you cross small cities such as Plymouth and Brewster.
We can conclude that although is so close to Boston, the large portion of the water of Cape Cod forces people to take the highway to get to Provincetown, Massachusetts, a coastal place with good beaches and tourist attractions.

Why is the rock cycle important to the recycling of material on Earth? Provide an example.
Answer:
The rock cycle is important to the recycling of material on Earth because it is a non-stop process. For example, pieces of the Grand Canyon, sediments, are carried by the wind or water, and then it gets deposited. As more sediments fall where the deposition pit is, the more rock starts to build up, and new rocks are formed.

Look at the graphs, which are different ways to measure something decreasing over distance or time. Based on your experiment, which graph resembles the way the sun’s energy decreases over distance?
Answer:
Inverse relationship.
Explanation:
There is inverse relationship present between energy and distance because when one increases the other decreases. when the distance between objects increases, the energy decreases while on the other hand, when the distance decreases, the energy between objects increases. Sun is present at one place so if an object go farther from the sun, the intensity of the sun decreases and vice versa.

Answer:
Option B
Explanation:
The higher the solute concentration the higher is the density of the solution. Hence, water with high salinity will have high density.
Hot water has energized atoms and molecules which increase fluidity of water as viscosity is reduced. On the other hand cold water has high viscosity and hence it is denser than hot water.
Thus, Water having high salinity and low temperature will be more dense.
