Answer:
-1/2
Explanation:
Solving the equation for y, we can find the slope of the given line. It is the coefficient of x.
y = 2x -5 . . . . . slope = 2
The slope of the perpendicular line will be the opposite reciprocal:
m = -1/2 . . . . . slope of perpendicular line
Answer: The size of the sparrow population would decrease dramatically to meet the demands of many predators, the hawks. Because the Hawks’s population increased so suddenly it would mean that more and more hawks would need to eat and their food sources is the small sparrow. Therefore the sparrow population would decrease due to too many predators hunting.
Answer:
The lithosphere
Explanation:
The lithosphere is the rocky outer part of the Earth . It is made up of the brittle crust and the top part of the upper mantle . The lithosphere is the coolest and most rigid part of the Earth .
Answer:
Coal: 7.4 billion tonnes
Explanation:
The World Coal Association estimates that there are more than one trillion tonnes of coal reserves worldwide, enough to last 150 years at current rates of production, so it is unsurprising to see coal ranked as the most-mined mineral in the world.
While China has consistently led the world in production – the country was responsible for 3.3 billion tonnes in 2016 – this was down 16% from the 3.9 billion tonnes produced in 2012. Chinese coal output slumped below the 3.4 billion tonne-threshold predicted in 2016 and the trend may continue, as renewable energy sources become more widespread.
The Chinese decline has mirrored a trend in worldwide coal production, which fell to 7.4 billion tonnes in 2016 from 8.2 billion in 2012. While coal production has increased in Australia and Russia in the last five years, both South Africa and the US have seen sharp declines in production of anthracite and bituminous coal. American coal production in particular has fallen from over 900 million tonnes in 2012 to 782 million in 2016, the lowest figure since 1979.

The answer is TOSH.
Tropical, subtropical, temperate, and alpine vegetation can all be found in the Himalayas, and each variety predominates in a region primarily influenced by elevation and precipitation. The species found in each zone vary significantly due to local variations in relief, climate, and exposure to wind and sunlight.
- The humid Himalayan foothills in the east and center are the only places where tropical evergreen rainforest can be found. The evergreen dipterocarps, a group of common trees that produce resin and timber, thrive on a variety of soil types and steepnesses in hill slopes. Oaks (genus Quercus) and Indian horse chestnuts (Aesculus indica) grow on the lithosol (shallow soil made up of imperfectly weathered rock fragments), which covers sandstones from Arunachal Pradesh westward to central Nepal at elevations of 3,600 to 5,700 feet. Mesua ferrea, a species of Ceylon ironwood, grows on porous soils between 600 and 2,400 feet (180 and 720 metres) (1,100 to 1,700 metres). On the steeper slopes, alder trees (genus Alnus) can be found growing alongside watercourses. Higher elevations cause certain species to succumb to mountain woods, where Himalayan screw pine serves as the predominant evergreen (Pandanus furcatus). Aside from those trees, it is thought that the eastern Himalayas are home to 4,000 species of blooming plants, 20 of which are palms.
