Step-by-step explanation:

The ratio of the volumes of the Spaceship Earth to a golf ball = 1926949795 : 1

We need to find the volumes of the Spaceship Earth and a golf ball.

Spaceship Earth

Radius, R = 165/2 ft = 82.5 ft

Volume of the Spaceship Earth = [tex]\frac{4\pi R^3}{3}[/tex] = (4 x 3.14 x 561515.625)/3

                                                    = 2350878.75 cubic ft.

A golf ball

Radius = 1.5/2 inches = 0.75 inches

1 ft = 12 inches

So 0.75 inches = 0.75/12 = 0.0625 ft.

So radius, r = 0.0625 ft

Volume of a golf ball =  [tex]\frac{4\pi r^3}{3}[/tex] = (4 x 3.14 x [tex]0.0625^3[/tex])/3

                                   = 0.00122 cubic ft.

Ratio of the volumes of Spaceship Earth to a golf ball

                    = 2350878.75:0.00122

                    = 1926949795 : 1

Answer:5/25,25, 0.3

Step-by-step explanation:

Answer:

5/25 , 25% , 0.3

Step-by-step explanation:

first let's change everything into decimals

0.3 is already a decimal

25% can be changed into 0.25

5/25 can be changed into a percentage first like 25%

so:

[tex]\frac{5}{25}[/tex] × [tex]\frac{4}{4}[/tex] (you multiply both sides by 4 because you need to have the denominator as a 100 and 25 x 4 = 100)

[tex]\frac{5}{25}[/tex] × [tex]\frac{4}{4}[/tex]  = [tex]\frac{20}{100}[/tex]

this means that the percentage is 20% now lets change that into a decimal like we did with 25% earlier:

20% = 0.20

we can then order everything from least to greatest:

0.20 , 0.25 , 0.3

or

5/25 , 25% , 0.3

Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.

If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).

Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.

c^2 = a^2 + b^2

where c is the total displacement from the starting point to the end point

a is the distance he walks up north

b is the distance he walks to the west

c^2 = 100^2 + 100^2

c^2 = 10,000 + 10,000

c^2 = 20,000

c = 141.42 meters

Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.

100 meters + 100 meters - 141.42 meters = 53.58 meters

Vertically Stretching and Compressing

Multiplying a function by positive constant yields a function whose graph is vertically stretched or compressed relative to the original function's graph. If the constant is greater than 1, it will stretch vertically. If the constant is between 0 and 1, vertical compression is done. You get vertical compression.

Vertical compression occurs when you multiply the function by a rational scaling factor. The base of the function graph remains the same even when the graph is compressed vertically. Only initial values ​​are affected.

Reflect across the x-axis Vertically stretch a factor of 3/2

Step-by-step explanation:

After solving the equation, x < -3 is the value of inequality 2-3 x<11

⇒ 2-3x < 11

⇒ -3x < 11 - 2

⇒ -3x < 9

⇒ x < -9/3

⇒ x < -3

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

According to the question, every morning Sally takes same bus and she has to wait to arrive with the used method called as uniform distribution.

And the range of the interval is as: min = 0 and max = 10.

For the calculation of the uniform distribution, the height some be constant.

Now, using standard uniform distribution formula:

Mathematically, the function  f(x) can be written as:

f(x) = 1/(b - a)

where, 'a' and 'b' are defined intervals. Here, a = 0; b = 10.

Now, to calculate the percentage form the area as a rectangular grid which means:

f(x) = 1/10(5.3 - 2.5) = 2.8/10 = 0.28 = 28 percent.

Now, to know the percentile using above data:

f(x) = 1/(b - a) = 7/10 = 0.7 = 70 percent.

Write an equation of the line with the given slope and y -intercept. Use slope-intercept form. Then rewrite the equation in standard form. m=3, b=-7

How to write the equation in slope-intercept form?

Given:

m=3(slope)

b=-7(y -intercept)

The slope-intercept form is given by,

y=mx+b

y=3x-7

Thus, y=3x-7 is the slope-intercept form.

How to rewrite the equation in standard form?

Standard form is given by,

Ax+By=C

Since, slope-intercept form is y=3x-7

⇒3x-y=7

Thus,3x-y = 7  is the standard form.

The sum of the given finite series is 100

The summation notation tells us how to sum each term in a series.

Example:

             [tex]\sum\limits^5_{n=1} {3n+1}[/tex]

means we need to evaluate the sum of (3n+1) as n moves from 1 to 5.  Here 1 is the lower limit, while 5 is the upper limit.

The given series is:

            [tex]\sum\limits^4_{n=1} {n^{3}}[/tex]

Expand this series:

          [tex]\sum\limits^4_{n=1} {n^{3}}=1^{3}+2^{3}+3^{3}+4^{3}[/tex]

1³ = 1

2³ = 8

3³ = 27

Parentheses are notated for non-inclusion(3 isn't included in the solution) and brackets are notated for inclusion(5 is included in the solution).

The values for the variables 'x' and 'y' are (3,7).

According to the question, to calculate the value of 'x' and 'y' then equate both the equations.

The given expressions are:

Equation (1): x + (1/7)y = 4 ⇒ 7x + y = 28

Equation (2): y = 3x - 2

Solving equation (1) and equation (2) by substituting the value of the 'y':

Therefore, 7x + 3x - 2 = 28 ⇒ 10x = 30 ⇒ x = 3

Now: y = 3(3) - 2 = 7

Hence, the values are: x = 3 and y = 7.
