Water is a resource that humanity has gone to great lengths to obtain. We have tried to save rainwater, dug deep wells, diverted rivers, created lakes, built long aqueducts, and spent huge amounts of energy to desalinate sea water. In the process we have often ruined good cropland by making it too salty to grow crops. We have fought wars over water supply, and will do so again. What percentage of the Earth's water is freshwater available from lakes and rivers

Answers

Answer 1

Answer: 1.2%

Explanation:

Even thought it seems like there is plenty of surface water on Earth, it is vastly below the quantity that exists in the oceans. which comprise of about 96.5% of the entire global water quantity.

When it comes to freshwater, most of it is locked up in ice caps and glaciers with only 1.2% coming from rivers, lakes and ground ice. If humans can find an efficient way to desalinize ocean water, we would not have to worry about water supply for eons.

WHY IS FAST FOOD SO POPULAR? And how does this relate back to Human Geography? Please ANSWER BOTH PARTS!

Answers

1.Ok fast food is popular because its cheap and it does not cost as much as a fancy restaurant. And it's not like it has a bad taste to it it taste good but however the cheaper it is the cheaper it taste.  

2.The availability of food high in fat, salt and sugar through Fast Food (FF) or takeaway outlets, is implicated in the causal pathway for the obesity epidemic. This review aims to summarise this body of research and highlight areas for future work. Thirty three studies were found that had assessed the geography of these outlets. Fourteen studies showed a positive association between availability of FF outlets and increasing deprivation. Another 13 studies also included overweight or obesity data and showed conflicting results between obesity/overweight and FF outlet availability. There is some evidence that FF availability is associated with lower fruit and vegetable intake. There is potential for land use policies to have an influence on the location of new FF outlets. Further research should incorporate good quality data on FF consumption, weight and physical activity.

Explanation:

mostly because if your trying to make solutions that could help a crowded city improve its management of water supplies you wouldn't want unregulated dumping in rivers and creeks or help citizens use more water on agricultural crops and encouraging citizens to grow water-intensive crops is the same thing as the other but not all people have crops.

If a stream has a steep slope or gradient, it will have a faster velocity, which means it will be able to carry larger materials in suspension. At flood stage, rivers flow much faster and do more erosion because the added water increases the stream's velocity.

Find the perimeter of a quadrilateral with vertices at C (−2, 4), D (−3, 1), E (1, 0), and F (−1, 2). Round your answer to the nearest hundredth when necessary.

10 units
10.77 units
11.52 units
12.35 units

Answers

Answer:

Perimeter of quadrilateral =  12.35 units

Explanation:

To find - Find the perimeter of a quadrilateral with vertices at C (−2, 4), D (−3, 1), E (1, 0), and F (−1, 2).

Proof -

The figure becomes :

We have the points -

C (−2, 4),

D (−3, 1),

E (1, 0),

F (−1, 2)

Now,

We know that -

The perimeter = Distance of (CD + DE + EF + FC)

Now,

Distance of CD = √(-3 + 2)² + (1 - 4)²

                         = √(-1)² + (-3)²

                         = √1 + 9

                         = √10 = 3.16

⇒Distance of CD = 3.16

Now,

Distance of DE = √(1 + 3)² + (0 - 1)²

                         = √(4)² + (-1)²

                         = √16 + 1

                         = √17 = 4.12

⇒Distance of DE = 4.12

Now,

Distance of EF = √(-1 - 1)² + (2 - 0)²

                         = √(-2)² + (2)²

                         = √4 + 4

                         = √8 = 2.83

⇒Distance of EF = 2.83

Now,

Distance of FC = √(-2 + 1)² + (4 - 2)²

                         = √(-1)² + (2)²

                         = √1 + 4

                         = √5 = 2.24

⇒Distance of FC = 2.24

So,

Perimeter of quadrilateral = 3.16 + 4.12 + 2.83 + 2.24

                                           = 12.35 units

Perimeter of quadrilateral =  12.35 units

Based on the information given, the perimeter of the quadrilateral will be 12.35 units.

Calculating the perimeter.

From the information given the distance of CD will be:

= ✓1 + ✓9

= 3.16

The distance of DE will be:

= ✓16 + ✓1

= 4.12

The distance of EF will be;

= ✓4 + ✓4

= 2.83

The distance of FC will be:

= ✓1 + ✓4

= 2.24

Therefore, the perimeter will be:

= 3.16 + 4.12 + 2.83 + 2.24

= 12.35 units

x³+ax²+bx+6 has (x-2) as factor and leaves remainder 3 when divided by (x-3), find values of a and b​

Answers

Explanation:

P(x) = x^3 + ax^2 + bx + 6

________________________________

Reminder :

x - a = 0 ==》 x = a

P(a) = Reamaining of the diving P(x) by

( x - a )

________________________________

x - 2 = 0 ==》x = 2 ==》P(2) = 0

(2)^3 + a(2)^2 + b(2) + 6 = 0

8 + 4a + 2b + 6 = 0

4a + 2b + 14 = 0

4a + 2b + 14 - 14 = 0 - 14

4a + 2b = - 14

( 4a + 2b ) ÷ 2 = ( -14 ) ÷ 2

2a + b = - 7 ( ♡ )

x - 3 = 0 ==》 x = 3 ==》P(3) = 3

(3)^3 + a(3)^2 + b(3) + 6 = 3

27 + 9a + 3b + 6 = 3

9a + 3b + 33 = 3

9a + 3b + 33 - 33 = 3 - 33

9a + 3b = - 30

( 9a + 3b ) ÷ 3 = ( - 30 ) ÷ 3

An archaeologist found some maps made by an ancient civilization. Which ancient map would be the most likely to show local trade routes

Answers

Answer:

A thematic map would be more likely to show local trade routes.

Explanation:

Thematic maps represent the terrestrial surface, taking into account some specific element. Thus, thematic maps, in addition to presenting the physical characteristics of the region, can present elements capable of facilitating the reading of the map and presenting more information to the observer. In this way, a thematic map can show the location of monasteries, forests and even trade routes.

In this case, we can consider that a thematic map would probably present local commercial routes.
