15/10=1.5

Answer:

Given

Number of stacks = 2

Stack 1 = 6 cups; h1 = 15cm

Stack 2 = 12 cups; h2 = 23cm

Let's first find the average:

With an average of 4/3, to obtain the number of cups needed to obtain a height of 50m, we have:

50 / (4/3)

= 50 * 3/4

= 150/4

= 37.5

From the answer, we can see that the number of cups is not really proportional to the height of the stack, because the average of stack one and stack 2 are different.

All the possible values for the number are \(x=2+2i\sqrt{3}\) and \(x=2-2i\sqrt{3}\).

Given that, a number plus 16 times its reciprocal equals 4.

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

Let the unknown number be x.

Now, the equation is \(x+\frac{16}{x}=4\)

\(\frac{x^2+6}{x}=4\)

\(x^2+16=4x\)

\(x^2-4x+16=0\)

By comparing \(x^2-4x+16=0\) with \(ax^2+bx+c=0\), we get a=1, b=-4 and c=16.

Substitute these values in quadratic formula \(x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}\), we get

\(x=\frac{4\pm\sqrt{(-4)^2-4\times1\times16} }{2\times1}\)

\(x=\frac{4\pm\sqrt{-48} }{2}\)

\(x=\frac{4\pm4i\sqrt{3} }{2}\)

\(x=2+2i\sqrt{3}\) and \(x=2-2i\sqrt{3}\)

Therefore, all the possible values for the number are \(x=2+2i\sqrt{3}\) and \(x=2-2i\sqrt{3}\).

Answer:

1. 58.0644

2. 0.01

3. 14.16

Step-by-step explanation:

1. V = l*w*h

   v = 7.62*7.62*1

   v = 58.0644

              or

    v = 7.62*7.62*6

    v = 348.3864

    v = 348.3864/6

     v =  58.0644

2. 1cm/ 100 sticky notes = 0.01

    6cm/ 600 sticky notes = 0.01

3. A=2πrh+2πr2

      =2·π·1.5·2×0.002+2·π·1.52

      =14.15602

The volume of each section will be 58.09364\(cm^3\). The height of one sticky note is 0.06 cm and the surface area of one sticky note is  0.02376 sq inch.

1)The volume of one sticky note can be calculated using the formula for the volume of a rectangular prism :\(V = l \times w \times h\), where l is the length, w is the width, and h is the height.

Length (l) = 7.62 cm

Width (w) = 7.62 cm

Height (h) = 1 cm (for each colored stack)

Substituting the values into the formula:

V = \(7.62 cm \times 7.62 cm \times 1 cm\)

V = 58.09364\(cm^3\).

Since there are 100 sticky notes of each color, the volume of each section can be found by multiplying the volume of one sticky note by 100:

Volume of each section =\(58.09364 cm^3 \times 100\)

Volume of each section = 5809.364 cm³

Method 2: Using the total volume of the stack and proportions

The total volume of the stack can be calculated by multiplying the area of the base (length × width) by the total height of the stack.

Given:

Length (l) = 7.62 cm

Width (w) = 7.62 cm

Height of stack = 6 cm

Volume of stack = l × w × height of stack

Volume of stack =\(7.62 cm \times 7.62 cm \times 6 cm\)

Volume of stack = 349.52544\(cm^3\) (rounded to five decimal places)

Since the stack contains 600 sticky notes in total and each section represents one-sixth of the stack, we can calculate the volume of each section by dividing the total volume by 6:

Volume of each section = Volume of stack  divided by 6

Volume of each section =\(\dfrac{349.52544 }{6} cm^3\)

Volume of each section = 58.25424 cm³ (rounded to five decimal places)

The height of one sticky note, we can divide the total height of the stack by the number of sticky notes of each color.

Method 1: Direct division

The height of one sticky note can be found by dividing the total height of the stack by the number of sticky notes in each colored section.

Height of stack = 6 cm

Number of sticky notes per color = 100

Height of one sticky note = \(\dfrac{Height of stack } {Number\ of \ sticky \ notes \ per \ color}\)

Height of one sticky note =\(\dfrac{6}{100}cm\)

Height of one sticky note = 0.06 cm

By Using proportions, method 2 can be solved

Since each colored section represents one-sixth of the stack, the height of one sticky note can be found by multiplying the height of the stack by \(\dfrac{1}{6}\).

Height of stack = 6 cm

Height of one sticky note =\(Height of stack \times\dfrac{1}{6}\)

Height of one sticky note =\(6\times \dfrac{1}{6}\)

Height of one sticky note = 1 cm

To find the surface area of one sticky note in the circular stack, we need to calculate the surface area of the cylinder and then divide it by the number of sticky notes.

Total number of sticky notes = 400

Diameter of cylinder = 3 in

Height of cylinder = 0.8 in

\(\pi\) = 3.14

Calculate the surface area of the cylinder using the formula for the lateral surface area of a cylinder:\(A = 2\pi rh\), where r is the radius and h is the height.

Radius (r)  = \(\dfrac{3}{2}\)  = 1.5 in

Lateral Surface Area (A) = \(2\pi rh\)

A = \(2 \times 3.14 \times 1.5 \times 0.8\) in

A = 9.504 sq inch (rounded to three decimal places)

Since there are 400 sticky notes, we can calculate the surface area of one sticky note by dividing the total surface area by 400:

Surface area of one sticky note = \(\dfrac{A}{Total\ number of \ sticky \ notes}\)

Surface area of one sticky note = \(\dfrac{9.504 }{400}sq \ inch\)

Surface area of one sticky note ≈ 0.02376 sq inch.

The volume of each section will be 58.09364\(cm^3\). The height of one sticky note is 0.06 cm and the surface area of one sticky note is  0.02376 sq inch.

Answer:

Step-by-step explanation:

diameter of the circle = 9 cm

side of square = 5 cm

As we know that the diagonal is maximum dimension in case of square, so if the length of diagonal is less than the diameter of the circle, then the square can fit into the circle else not.

First we need to find the length of the diagonal.

Let the length of diagonal is D.

By use of Pythagoras theorem

D = 7.07 cm

As the length of the diagonal is less than the diameter of the circle, so the square can fit into the circle.
