Question: What is the surface area of the cube?

Answer:

[tex]Area = 216\ in^2[/tex]

Step-by-step explanation:

Given

[tex]L = 6[/tex] --- length

Required

Determine the surface area

The surface area of a cube is calculated as follows:

[tex]Area = 6L^2[/tex]

Substitute 6 for L

[tex]Area = 6 * 6^2[/tex]

[tex]Area = 6 * 36[/tex]

[tex]Area = 216[/tex]

Hence, the surface area of the cube is [tex]216in^2[/tex]

Answer:

[tex]L^{-1} (\frac{5s}{s^{2}+ 3 s -4 } )[/tex] =  [tex]4e^{-4t} + e^{t}[/tex]

Step-by-step explanation:

Step(i):-

Given

           [tex]L^{-1} (\frac{5s}{s^{2}+ 3 s -4 } )[/tex]

Factors of    s² + 3s - 4

               =    s² + 4s - s -4

               =   s( s +4 ) -1 (s +4)

               =   (s-1)(s+4)

  [tex]L^{-1} (\frac{5s}{s^{2}+ 3 s -4 } )[/tex]

              =    [tex]L^{-1} (\frac{5s}{s+4)(s-1) } )[/tex]

By using partial fractions

           [tex](\frac{s}{s+4)(s-1) } ) = \frac{A}{s+4} + \frac{B}{s-1}[/tex] ..(i)

                s  = A ( s-1) + B( s+4) ....(ii)

          Put s= 1  in equation (ii) , we get

             1 = B(5)

           [tex]B = \frac{1}{5}[/tex]

         s = -4 in equation (ii) , we get

        -4 = -5A

         [tex]A =\frac{4}{5}[/tex]

Step(ii):-

    now the equation (i) , we get

[tex](\frac{s}{s+4)(s-1) } ) = \frac{4}{5(s+4)} + \frac{1}{5(s-1)}[/tex]

[tex]L^{-1} (\frac{s}{s+4)(s-1) } ) = 5( L^{-1} \frac{4}{5(s+4)} + 5L^{-1} \frac{1}{5(s-1)}[/tex]                      

By using inverse Laplace transform formula

[tex]L^{-1} (\frac{1}{s-a} ) = e^{at}[/tex]

[tex]L^{-1} (\frac{1}{s-1} ) = e^{t}[/tex]

[tex]L^{-1} (\frac{1}{s+4} ) = e^{-4t}[/tex]

[tex]L^{-1} (\frac{s}{s+4)(s-1) } ) = 5( L^{-1} \frac{4}{5(s+4)} + 5L^{-1} \frac{1}{5(s-1)}[/tex]                    

                      = [tex]4e^{-4t} + e^{t}[/tex]

Answer:

Option C (4096π in²)

Step-by-step explanation:

Area of the circle = 256π in²

We know that [tex]Area=\pi r^{2}[/tex] , where r = radius of the circle

So,

[tex]256\pi = \pi r^{2}[/tex]

Cancelling π from both the sides,

[tex]=> r^{2} = 256[/tex]

[tex]=> r = \sqrt{256} = 16[/tex]

The radius of the circle = 16 in.

When the radius is multiplied with 4 , new radius = 16×4 = 64 in.

New Area = [tex]\pi (64)^{2} =4096\pi \: in^{2}[/tex]

Answer: C

-10 = b

34 =c

Insert these values into the quadratic formula

Answer:

the weighted score is 82.03

Step-by-step explanation:

The computation of the weighted score is as follows

= Respective scores × respective test or exam and score

= 0.21 × 90 + 0.24 × 71 + 0.24 × 71 + 0.31 × 79

= 18.9 + 21.6 + 17.04 + 24.49

= 82.03

Hence, the weighted score is 82.03

We simply applied the above formula so that the weighted score could be come

24 = 31.4n + (-8.4) is the correct answer

Step-by-step explanation:

expression  31.4n -8.4 = 24 is the correct equation for the given sentence.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given,  twenty-four is the same as 31.4 times a number plus negative 8.4.

Let " n " be the number

From the given data expression will be,

31.4 times a number

=> 31.4 * n

plus negative 8.4

=> 31.4n -8.4

Equals to twenty-four

=>  31.4n -8.4 = 24

Therefore, expression  31.4n -8.4 = 24 is the correct equation for the given sentence.

Answer:

y=3/4x+1/4

Step-by-step explanation:

Perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.

So, to find the slope of the new line, we can use this equation:

-4/3m=-1

multiply both sides by 3/-4

m=3/4

So the slope of the new line is 3/4

Here's the equation so far:

y=3/4x+b (b is a placeholder)

we can substitute the point (5,4) into the equation, since the line is going to pass through it.

4=3/4(5)+b

4=15/4+b

1/4=b

So the line is y=3/4x+1/4

Step-by-step explanation:

So what you need to do is is how fast they traveled every ten miles once you do that take how fast they traveled every ten miles and multiply it by 9.

So it seems to me that 1 day for most people they walked 10 miles. So if it takes 7 days for them to get there you need to do 90 divided by 7 which will get you your answer.

I hope this helped you understand better!

Expenses   Percentage   Degree

Housing            35%        130°  (360° * 35%)

Food                  14%         50°  (360° * 14%)

Auto                22%           80°  (360° * 22%)

b) The result shows that Housing expense took more than one-third of the circle with auto expenses occupying the next biggest chunk of the circle.  Clothing came third to occupy one-sixth of the circle, with food and entertainment trailing behind with less than one-sixth of the circle respectively.

  10.  x = 4

  11.  x = -5

Step-by-step explanation:

10. Use the perimeter formula. Collect terms, subtract* the constant, divide by the coefficient of the variable.

  P = 2(L+W)

  42 = 2(5x +(x-3))

  21 = 6x -3 . . . . . . divide by 2, collect terms

  24 = 6x . . . . . . . . add 3

  4 = x . . . . . . . . . .  divide by 6

11. Collect terms, subtract the constant, divide by the coefficient of the variable.

  -8x -3(2x +1) = 67

  -8x -6x -3 = 67 . . eliminate parentheses

  -14x -3 = 67 . . . . . collect terms

  -14x = 70 . . . . . . . add 3

  x = -5 . . . . . . . . . . divide by -14

* "Subtract" and "add the opposite" are the same mathematical operation. In both these problems, the constant we want to get rid of is -3, so we add 3 (the opposite of -3). Of course, that operation is done to both sides of the equation.

Answer:

Option 1: 28 is the correct answer.

Step-by-step explanation:

The given expression for sum is:

[tex]\[ \sum_{n=1}^{4} {2n+2} = 1 \][/tex]

There will be four terms in the sum

We have to find the terms by putting n=1,2,3,4 as n=1 to 4

Putting n=1

[tex]=2(1)+2 = 2+2 = 4[/tex]

Putting n=2

[tex]=2(2)+2 = 4+2 = 6[/tex]

Putting n=3

[tex]=2(3)+2 = 6+2 = 8[/tex]

Putting n=4

[tex]=2(4)+2 = 8+2 = 10[/tex]

So the summation will expand to:

[tex]\[ \sum_{n=1}^{4} {2n+2} = 1 \] = 4+6+8+10 = 28[/tex]

Hence,

Option 1: 28 is the correct answer.

C. the rate at the pool fills in feet per hour

Step-by-step explanation:

Given

The attached graph

Required

What does the slope represent?

The slope of any graph can be calculated using:

[tex]Slope = \frac{Rise}{Run}[/tex]

Where:

Rise = The change in the vertical axis

Run = The change in the horizontal axis within the same interval as the Rise

The vertical axis measures depth in feet and the horizontal axis measures time in hour.

So:

[tex]Slope = \frac{Depth}{Time}[/tex]

or

[tex]Slope = \frac{Feet}{Hour}[/tex]

This means that the slope measures rate in feet per hour

Answer:

45 plants

Step-by-step explanation:

Given that:

Length of bed = 120 in

Width of bed = 240 in

Perimeter of a rectangle is given by :

P = 2(length + Width)

Therefore,

P = 2(120 + 240)

Perimeter = 720 inches

If a spacing of 16 inches will be used ; number of plants needed ;

Perimeter / 16

= 720 in / 16 in

= 45
