<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>

Find hypotenuse,perpendicular and base​
Firdavs [7]

Answer:

Consider the angle Ф.

the line opposite to Ф is the perpendicular -> PQ = 5cm

The base is the line with whom the perpendicular has 90° angle -> PR = 12cm

Finally, hypotenuse is the line opposite to the 90° which is QR= 13cm

You are planning a party on a limited budget. In order to do so you will need to determine how much it will cost to rent a space
Mkey [24]

Answer:

$1,267.50

Step-by-step explanation:

assumption;

b = cost of rental space = $780

x = number of guests = 50 people

m = price of food per person = $9.75

y = total budget

y = mx + b

y = (9.75 * 50) + 780

y = 487.50 + 780

y = $1,267.50

Suppose that 1 kg of Sodium-24 is reduced to 0.0156 kg in 90 hours. What is the half-life, in hours, of Sodium-24?​
N76 [4]

Answer:

14.99 hours

Step-by-step explanation:

The formula for half-life is given as,

R/R' = 2ᵃ/ᵇ...................... Equation 1

Where R= Original mass of sodium-24, R' = mass of Sodium-24 after disintegration, a = Total time taken for sodium-24 to disintegrate, b = half-life of sodiun-24.

Given: R = 1 kg, R' = 0.0156 kg, a = 90 hours

Substitute into equation 1 and solve for b

1/(0.0156) = 2⁹⁰/ᵇ

Taking the log of both side

log[1/(0.0156)] = log(2⁹⁰/ᵇ)

log[1/(0.0156)] = 90/b(log2)

90/b = log[1/(0.0156)]/log2

90/b = 6.0023

b = 90/6.0023

b =  14.99 hours

b = 14.99 hours.

Hence the half-life of Sodium-24 is 14.99 hours

A circle has a circumference of 20π cm. What is the measure(in degrees) of an arc length of 4π cm?
Alexeev081 [22]

Answer:

The degree measure of the requested angle is 72^o

Step-by-step explanation:

Recall that the formula for the arc length (S) is given by:

s=R\,*\theta

where R is the circle's radius and the angle \theta (which is the angle subtended by the arc "S") must be given in radians.

So first, we need to find the radius of the circle, given the information on its circumference (20\,\pi \, cm).

Since the circumference of a circle is given by: 2\,\pi\,R,

then we can find what the radius is in our case:

2\,\pi\,R = 20\,\pi\,\,cm\\R=\frac{20\,\pi}{2\,\pi} \,cm\\R=10\,\,cm

Now, with the radius (10 cm) we can use the arc length formula to find the subtended angle  \theta  in radians:

s=R\,*\theta\\4\,\pi\,\,cm=(10\,\,cm)\,\theta\\\theta=\frac{4\,\pi}{10} \\\theta=\frac{2}{5} \,\pi

Now we find the degree equivalent to this angle, via multiplying it by \frac{180^o}{\pi}, which renders:

\frac{2}{5} \pi\,(\frac{180^o}{\pi} )=72^o

So this is the degree measure of the requested angle.
