Describe how ice-albedo feedback causes global warming

Answers

Answer 1
Ice-albedo feedback is a strong positive feedback in the climate system. Warmer temperatures melt persistent ice masses in high elevations and upper latitudes. Ice reflects some of the solar energy back to space because it is highly reflective.

4) The diameter of a circle is 32m. The radius is represented by 4(x + 2).
Part A: Write an equation you can use to find the value of x.
Part B: What is the value of x?

Answers

Answer:

The value of x is 2

Step-by-step explanation:

Diameter = 2r -------------------------------------------------------------------(1)

where r is the radius

The value of the diameter = 32 m   and  radius is given to be 4(x+2)

substitute the above into equation (1)   and then solve for x

32  =  2 [ 4(x + 2)]

first open the inner bracket

32 = 2[4x + 8}

then open the outer bracket

32 = 8x + 16

subtract 16 from both-side of the equation

32 - 16 = 8x +16 - 16

16 = 8x

Divide both-side of the equation by 8

16/8  = 8x/8

2 = x

x = 2

Therefore, the value of x is 2

Consider the triangle ABD,

Here,

AB = 5

BD = 15

AD = s

As we know,

In a triangle, the sum of lengths of two sides is greater than the third side.

So,

[tex]5 + 15 > s[/tex]

[tex]15 + s > 5[/tex]

[tex]s + 5 > 15[/tex]

Now,

To satisfy the equation, the value of s can possibly be 11, 12, 13, 14, 15, 16, 17, 18, 19

Solve 2x+7>+x +19
and can you do the same if 2 was 3.

2nd question is write an expression if 3 was open inequality and line continues past negative 5

Answers

Answer:

Step-by-step explanation:

Original problem:

2x + 7 > x + 19

Subtract x from both sides.

x + 7 > 19

Subtract 7 from both sides.

x > 12

Problem with 3 instead of 2.

3x + 7 > x + 19

Subtract x from both sides.

2x + 7 > 19

Subtract 7 from both sides.

2x > 12

Divide both sides by 2.

x > 6

2nd question (I'm not sure I understand it correctly.)

x < 3

Solving 2x + 7 > x + 19

2x + 7 > x + 19

Move 7 by subtracting from both sides.

2x > x + 19 - 7

2x > x + 12

Move x by subtracting from both sides.

2x - x > 12

x > 12

Therefore, x is greater than 12.

Solving 3x + 7 > x + 19

3x + 7 > x + 19

Move 7 by subtracting from both sides.

3x > x + 19 -7

3x > x + 12

Move x by subtracting from both sides.

3x - x > 12

2x > 12

Divide 2 on both sides to get x.

2x/2 > 12/2

x > 6

Therefore, x is greater than 6.

Part 2:

Write an expression for if 3 was open inequality and line continues past negative 5.  This may not be correct due to the vagueness of what it's asking.

Expression: x < -5 < 3

x indicates all real numbers less -5

3 is open inequality and is the greatest

The 2nd question is like really vague.

45,239 m2
50,265 m2

Answers

Answer:

The lateral surface area of the cone is [tex]25120\ m^2[/tex].

Step-by-step explanation:

We have.

Height of a cone is 60 m

Diameter of a cone is 10 m

Radius, r = 80 m

The lateral surface area of a cone is given by :

[tex]A=\pi rl[/tex]

l is slant height of the cone,

[tex]l=\sqrt{60^2+80^2} =100\ m[/tex]

Plugging all values in above formula,

[tex]A=3.14\times 80\times 100\\\\A=25120\ m^2[/tex]

So, the lateral surface area of the cone is [tex]25120\ m^2[/tex].

What is the arc measure of BAD on circle P in degrees?

Answers

Answer:

arc BAD = 244°

Step-by-step explanation:

The sum of the angles around the centre of the circle = 360°, thus

∠APD = 360° - (136 + 74 + 42)° = 360° - 252° = 108°

The angle at the centre is equal to the arc that subtends it, thus

arc BAD = arc BA + arc AD = 136° + 108° = 244°

The requried measure of arc BAD on circle P is given as  244°.

What are the angle?

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

The Arc of the whole circle measures, 2π = 360°,
Angle ∠APD is given as

∠APD = 360° - (136 + 74 + 42)°
∠APD   = 360° - 252° = 108°

The angle at the center is equal to the arc that subtends it, thus

Arc BAD = Arc BA + Arc AD
Arc BAD = 136° + 108° = 244°

Thus, the requried measure of arc BAD on circle P is given as  244°.

Jessie lives in a farm and only has 2 animals, chickens and rabbits. One day he decided to count the total number of heads and legs of his animals. He told his friends that there were 30 heads and 76 legs in all.
How many chickens does Jessie have on his farm?
How many rabbits does Jessie have on his farm?

Answers

Let x represent number of rabbits and y represent number of chickens.

We have been given that Jessie told her friends that there were total 30 heads for both animals. This means that there are total 30 animals.

[tex]x+y=30...(1)[/tex]

[tex]y=30-x...(1)[/tex]

We have been given that Jessie only had chicken and rabbits. We know that a rabbit has 4 legs, so total number of legs for x rabbits would be [tex]4x[/tex].

We know that a chicken has 2 legs, so total legs of y chickens would be [tex]2y[/tex].

Since all animals has 76 legs in all, so we can represent this information in an equation as:

[tex]4x+2y=76...(2)[/tex]

Upon substituting equation (1) in equation(2), we will get:

[tex]4x+60-2x=76[/tex]

[tex]2x+60=76[/tex]

[tex]2x+60-60=76-60[/tex]

[tex]2x=16[/tex]

[tex]\frac{2x}{2}=\frac{16}{2}[/tex]

[tex]x=8[/tex]

Therefore, Jessie have 8 rabbits on his farm.

Number of chickens would be [tex]y=30-x\Rightarrow 30-8=22[/tex].

Therefore, Jessie have 22 chickens on his farm.

Doug is a dog, and his friend Bert is a bird. They live in Salt Lake City, where the streets are 1/16 miles apart and arranged in a
square grid (see map). They are both standing at the corner of 6th avenue and L street. Doug can run at an average speed of 30
mi/hr through the streets of Salt Lake, and Bert can fly at an average speed of 20 mi/hr. They are about to race to the corner of
10th avenue and Estreet. who would win and why?

Answers

No map given but it shouldn't matter.

E is the 5th letter, L the 12th.

Start at S(6,12).  End at E(10,5)

The vector between them, E-S=(4,-7)

Each unit is 1/16 of a mile, though that probably doesn't matter that much.

Doug has to stay on the grid, so has to run |4|+|7|=11 units.  At 30 mi/hr that takes (11/16)/30 =  0.022916 hours.

Bert can go diagonally, so flies √(4²+7²)=√65 ≈ 8.06 units.  At 20 mi/hr that takes (8.06/16)/20 = 0.025194 hours.

Answer:  Doug wins

Why? Because it's quicker to cover 4+7 at 30 mph than it is to cover √(4²+7²) at 20 mph.  That is, Doug is 1.5 times faster and the 1.5 times the diagonal distance is more than the grid distance.

Answer:

Doug wins. He finishes in 1.38 minutes. Bert takes 1.51 minutes.

Step-by-step explanation:

Each city block is a square 1/16 mile by 1/16 mile.

From 6th Av and L Street to 10th Av and E Street, they need to go 4 avenues and 7 streets over. These two distances along blocks are the legs of a right triangle. The right triangle has legs of length 4 * 1/16 mile and 7 * 1/16 mile.

leg1 = 4 * 1/16 mile = 0.25 mile

leg2 = 7 * 1.16 mile = 0.4375 mile

The hypotenuse of the right triangle can be calculated by the Pythagorean theorem.

a^2 + b^2 = c^2

(0.25 mile)^2 + (0.4375 mile)^2 = c^2

c = 0.50389

The direct distance from one corner to the other is 0.50389 miles.

The bird travels this distance since the bird can fly above the streets.

The dog has to travel along the legs of right triangle by running in the streets and avenues. The dog travels 0.25 mile + 0.4375 mile = 0.6875 miles

Now we need to see what takes less time:

Bird: distance of 0.50389 miles at 20 mph, or

Dog: distance of 0.6875 miles at 30 mph

We start with the formula for speed:

speed = distance/time

s = dt

Now we solve it for time:

st = d

t = d/s

Time equals distance divided by speed.

Now we find the times for the bird and for the dog.

Bird:

t = d/s = (0.50389 mi)/(20 mi/h) = 0.02519 hours = 1.51 minutes

Dog:

t = d/s = (0.6875 mi)/(30 mi/h) = 0.0229 hours = 1.38 minutes

The bird takes 1.51 minutes, and the dog takes 1.38 minutes.

The dog takes less time to get there, so the dog wins.
