Which gases are released into the atmosphere when volcanoes erupt?

Answers

Answer:

The volcanoes are formed adjacent to a convergent plate boundary, in which the denser plate subducts under a less denser plate. These subducting plates undergoes partial melting at greater depths and the magma is forced to rise up towards the over-riding plate, resulting in the formation of the volcano and chains of volcanoes.

These volcanoes when undergoes eruptions, releases various types of gases. They are such as the Carbon dioxide (CO₂), Water vapor (H₂O), Sulfur dioxide (SO₂), Hydrogen sulfide (H₂S) and Carbon monoxide (CO).

These gases are harmful to the atmosphere as it creases the green house effect thereby increasing the earth's global temperature.

in response to rising concerns about identity theft the number of models of paper shredders a company manufactures increased approximately steadily from 2 models in 1998 to 36 model in 2008 what the average rate of change ​

Answers

Answer:

The average rate of change ​is m = 3.4 models of paper shredders per year

Step-by-step explanation:

The rate of change m of a function is:

[tex]m = \frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]

In this problem the function receives a variable x = year and returns a variable f(x) = models of paper shredders

We know that for [tex]x = 1998[/tex], [tex]f(x) = 2[/tex]

We also know that for [tex]x = 2008[/tex], [tex]f(x) = 36[/tex].

Then we can calculate the average rate of change using these values.

[tex]m = \frac{f(2008)-f(1998)}{2008-1998}[/tex]

[tex]m = \frac{36-2}{2008-1998}[/tex]

[tex]m = 3.4[/tex]

Final answer:

The average rate of change in the number of paper shredder models produced by the company from 1998 to 2008 is 3.4 models per year.

Explanation:

To calculate the average rate of change, we can use the formula (Change in Y) / (Change in X). In this case, 'Y' is the number of paper shredder models and 'X' is the time, in years. In 2008 the company manufactured 36 models which is an increase from the 2 models they made in 1998.

The change in 'Y' (ΔY) would therefore be (36 - 2) = 34. The change in 'X' (ΔX) would be (2008 - 1998) = 10 years. Therefore, the average rate of change would be ΔY / ΔX = 34 / 10 = 3.4.

This suggests that, on average, the company has been producing an additional 3.4 models of paper shredders each year over this 10 year period in response to rising concerns about identity theft.

What is the surface area of the cone? (Use 3.14 for π.)

Answers

Answer: 117.226666667 cm^3

Step-by-step explanation:

So, we all know the formula for working out the volume of a cone is

V= 1/3πr^2h

V = 1÷3 x 3.14 × r^2 x h

The radius is half the diameter. Your diameter is 8 so the radius would be 4. And 7 is your height by the way.

So let's plot it all in!

V= 1÷3 x 3.14 × 4^2 x 7

V = 117.226666667cm^3

Round to the nearest 10 = 117.2cm^3

To the nearest 100 = 117.23cm^3

To the nearest whole number = 117cm^3

Answer:

Surface area = 87.92 Sq Inch and Total surface area =138.16 Sq Inches

Step-by-step explanation:

Here we are required to find the surface area of a cone, The formula of surface area of a cone is given as under

r=4

l = 7

[tex]S_{s}=\pi*r*l[/tex]

[tex]S_{s}=3.14*4*7[/tex]

[tex]S_{s}=87.92[/tex]

Also the total surface area is given as

[tex]T_{s}=\pi*r^{2} + \pi*r*l[/tex]

We are given

Now we put the values of r and  l in main formula

[tex]s=\pi*4^{2} + \pi*4*7\\s=3.14*16+3.14*28\\s=50.24+87.95\\s=138.16[/tex]

What is exponents ?

Meaning of an exponent is the number of times a number is multiplied by itself.

An exponent is defined as a method of expressing large numbers in terms of powers. That is, the exponent refers to how many times a number is multiplied by itself. For example, 6 is multiplied by itself 4 times, i.e. 6 x 6 x 6 x 6. This can be written as 64. Here, 4 is the exponent and 6 is the base. It can be read by raising 6 to 4 degrees.

By some examples we can understand this concept.

Example -1,

[tex]2 \times 2 \times 2 = {2}^{3} [/tex]

Example -2,

[tex]5 \times 5 \times 5 \times 5 = {5}^{4} [/tex]

Example-3,

[tex]8 \times 8 \times 8 \times 6 \times 6 = {8}^{3} \times {6}^{2} [/tex]

We want to find what is the product of π⋅π⋅π⋅x⋅x⋅x⋅x using exponents.

Given, [tex]\pi.\pi.\pi.x.x.x.x[/tex]

Here,

[tex]\pi.\pi.\pi.x.x.x.x \\ = {\pi}^{3} \times {x}^{4} [/tex]

E) 20
F) -400^1/2​

Answers

Answer:
A)400^1/2

E)20

C)-20

F)-400^1/2

Final answer:

The square roots of 400 are represented by A) 400^1/2, C) -20, and E) 20. These correspond to the positive and negative values that, when squared, result in 400. Options B) 40, D) 10, and F) -400^1/2 do not square to 400 and are therefore incorrect.

Explanation:

To find the square roots of the number 400, we look for numbers that when multiplied by themselves will equal 400. The square root of a number can be both positive and negative since both will square to give the original number.

Option A (400^1/2) represents the principal square root of 400, which is found by raising 400 to the power of 0.5. This is equal to 20, so option A is correct.

Option B (40) is not a square root of 400 because 40 * 40 equals 1600, not 400.

Option C (-20) is the negative square root of 400 because (-20) * (-20) equals 400, so option C is correct.

Option D (10) is incorrect because 10 * 10 equals 100, not 400.

Option E (20) is the positive square root of 400, so this is correct.

Option F (-400^1/2) is the negative principal square root of -400. Since 400 is positive, this option is not applicable, so option F is incorrect.

Therefore, the correct square roots of 400 from the given options are A) 400^1/2, C) -20, and E) 20.

A city is building a fence around a rectangular playground. If the perimeter of the playground is 96 feet and the length of one side of the fence is 30 feet, what is the width of the playground?

Answers

Answer:

The answer is 18.

Step-by-step explanation:

Perimeter is P, length is L, and width is W. So, P is L plus L plus W plus W. If L is 30, then L plus L is 60. Do the P minus 60, which is 36. So, to find width, use that.

W plus W is the last part of P, and P minus 60 is 36. So, for one width, it is 36 divided by 2, which is our answer: 18.

Final answer:

To determine the width of the playground when the length of the fence is given as 30 feet and the perimeter is 96 feet, apply the formula for the perimeter of a rectangle and solve for the width, resulting in a width of 18 feet.

Explanation:

Given information:

Perimeter of the playground is 96 feet.

Length of one side of the fence is 30 feet.

To find: Width of the playground.

Step-by-step solution:

Let the length of the playground be L feet and the width be W feet.

Given, 2L + 2W = 96 (perimeter formula) and L = 30 (given)

Substitute L = 30 into the perimeter formula to find W: 2(30) + 2W = 96 => 60 + 2W = 96 => 2W = 36 => W = 18 feet.

Therefore, the width of the playground is 18 feet.

We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .

The formula for simple interest is given as

[tex]Interest = Principal \times Rate \times time [/tex]

[tex]116.25=1550 \times r \times \frac{9}{12}[/tex]

Final answer:

The solution to the given equation that results in positive integer values for x and y is x=3, y=1. Therefore, multiplying x and y together, xy = 3.

Explanation:

The given mathematical equation is (x·2)+x(2^2)+(y·2^3)+(y·2^4)=42. We can simplify this to 2x + 4x + 8y + 16y = 42, which simplifies further to 6x + 24y = 42. Dividing the whole equation by 6 to make the calculation simpler, we get x + 4y = 7. The solution to this equation that has positive integers for both x and y is x = 3, y = 1. Therefore, to find the value of xy, you simply multiply x and y together, and get xy = 3.
