Answer:

t=6

Step-by-step explanation:

ground height = 0

(are you sure your formula is correct? isn't it - 16t²?)

if h=16t² +64t+192 is true then

16t² +64t+192 = 0

t² + 4t + 12 = 0

t = (-4 ± √(4² - 4*12)) / 2*1 = (-4 ± √-32) / 2 = -2 ± 2√-2

There is no solution of t

if it is h= - 16t² +64t+192

0 =- 16t² + 64t + 192

t² - 4t - 12 = 0

(t + 2) (t -6) = 0

t should be positive

t = 6 sec

by selling a mobile set of rupees 4800 Ramesh gains 25% how much will have we gained by selling it at rupees 4080​
Crank

Answer:

240

Step-by-step explanation:

Gain=25%

Gain=selling price - cost price

Gain = ((selling price - cost price )× 100)/ cost price

25c=(4800-c)100

25c=480000-100c

125c=480000

cost price = 3840

second statement

The selling price was 4080

Cost price 3840

therefore

Gain=selling price - cost price

Gain = 4080-3840

=240

<u><em>The increased heat, disruption to the water cycle and loss of shade would take a deadly toll on billions of people and livestock. Poverty and death would also descend on many of the 1.6 billion people who currently rely directly on forests for their livelihoods, including for harvesting food and medicine. </em></u>

<u><em>When Amazon rainforest disappears, so does Amazon rain. That's because air passing over forests picks up moisture given off by trees and plants, fueling rains. ... When those trees disappear, so does some of that rain.</em></u>

<u><em>The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.</em></u>

<u><em>In conclusion...Without trees, we all die. Besides providing oxygen for us to breathe, trees make life on earth sustainable. ... Trees affect everything from the air we breathe to the rain that falls from the sky. Without a robust population of trees, we die and so does our planet.</em></u>
