For this case, we have that by definition:

ρ = [tex]\frac {M} {V}[/tex]

Where:

ro: Density

M: Mass

V: Volume

We find the volume of the pyramid:

[tex]V = \frac {1} {3} * l ^ 2 * h[/tex]

Where:

[tex]l ^ 2[/tex]: Represents the area of the base of the square pyramid

h: Represents the height

So:

[tex]V = \frac {1} {3} * (6) ^ 2 * 2.5\\V = \frac {1} {3} * 36 * 2.5\\V = 30 \ in ^ 3[/tex]

We have to:

M = ρ* V

[tex]M = 0.258 \frac {lb} {in ^ 3} * 30 \ in ^ 3\\M = 7.74 \ lb[/tex]

So, you need 7.74 pounds of zinc

Answer:

7.74 pounds

Answer:

Domain: [tex]n\ge1[/tex]

Step-by-step explanation:

For a geometric sequence, the n-th term is given by:

[tex]a_n=a_1r^{n-1}[/tex]

From the question, [tex]a_1=1[/tex] and [tex]r=6[/tex].

Hence the explicit formula for the sequence is:

[tex]a_n=6^{n-1}[/tex], where [tex]n\ge1[/tex]

Therefore the domain is natural numbers or positive integers.

Answer:

The answer is A. F(x)=(X+3)^4

Step-by-step explanation:

1. Whenever the function is in parenthesis, the symbol does the opposite then it usually does. So for (X+3)^4, the + in the parenthesis shifts the graph to the left instead of right.

2. Also, when in parenthesis, function shifts horizontally, not vertically. So answers B and C would shift the graph up and down, instead of left or right.

Please feel free to ask me if you have more questions or concerns with this problem!

Answer:

Step-by-step explanation:

f(x) + n - shift the graph n unit up

f(x) - n - shift the graph n unit down

f(x + n) - shift the graph n unit to the left

f(x - n) - shift the graph n unit to the right

=======================================================

F(x) ← G(x) shifted 3 units to the left

F(x) = G(x + 3) → F(x) = (x+3)⁴

The Value of Pi is actually an infinite number and cannot be calculated. It is not a real number. Usually many just shorten Pi to the decimal 3.14, which it is most commonly used as since there is no exact decimal of Pi.

Pi is 3.14, and is an irrational number, meaning that it does not end and has no repetition of numbers in a row.

The area of the circle is calculated by multiplying pi by the radius.

3.14 * 10 = 314.16.

To round it to the nearest tenth, you must know whether the second decimal number is greater or less than 5. If it is 5 or greater, you round the first decimal up 1. If it is 4 or less, then you just remove the second decimal and keep the first one.

In this case, the answer would be approximately 314.2 because 6 is greater than 5, so you round up the 1 to a 2.

Answer:

Option A.  [tex]\frac{1}{16}[/tex]

Step-by-step explanation:

Two boxes contains the following pieces of chalk of the same size.

Red = 2

Yellow = 1

Green = 4

White = 3

Blue = 2

Each box contains = 2 + 1 + 4 + 3 + 2  = 12 pieces of chalk of the same size.

There are total pieces of chalks are 12 and white chalks are 3 in each box.

If one piece of chalk will be randomly selected from each box.

The probability of first box that piece will be white = [tex]P_{1}=\frac{3}{12}[/tex]

The probability of second box =  [tex]P_{2}=\frac{3}{12}[/tex]

Therefore,  P =  [tex]p_{1}[/tex] × [tex]p_{2}[/tex]

                   P = [tex]\frac{3}{12}[/tex] × [tex]\frac{3}{12}[/tex]

                   P = [tex]\frac{1}{4}[/tex] ×  [tex]\frac{1}{4}[/tex]

                   P = [tex]\frac{1}{16}[/tex]

The probability that both pieces will be white is  [tex]\frac{1}{16}[/tex] .

Answer:

Step-by-step explanation:

If the question mentions a graph, you'll need to share that graph.

Here's one good procedure for graphing -4x + y = 8:

Find the y-intercept:  Let x = 0 and solve for y.  We get (0, 8).  Plot this.

Find the x-int.  Let y = 0 and solve for x.  We get (-2, 0).  Plot this.

Then draw a straight line through these two points.

Answer:

4 inches.

Step-by-step explanation:

Convert 10ft in to inches

10 ft = 120 inches

So, 10ft/30inches =120inches/30 inches

120÷30=4

The requried, 10 ft / 30 inches simplified is 4

To simplify the expression 10 ft / 30 inches, we need to convert the units to a common format. We can convert both feet and inches to inches to make the division easier.

1 foot is equal to 12 inches. So, 10 feet can be written as 10 * 12 = 120 inches.

Now we have 120 inches / 30 inches, which simplifies to:

120 inches / 30 inches = 4.

Therefore, 10 ft / 30 inches simplified is 4.

Answer:

120

Step-by-step explanation:

We need the formula of combination:

nCr = [tex]\frac{n!}{(n-r)!*r!}[/tex]

Also we need to understand "factorial" notation, which is the "!" mark. For example, 5! means 5 * 4 * 3 * 2 * 1, and

4! would mean 4 * 3 * 2 * 1

Now we can find out 16C14 by plugging it into the formula and doing the steps shown below:

[tex]nCr=\frac{n!}{(n-r)!*r!}\\16C14=\frac{16!}{(16-14)!*14!}\\=\frac{16!}{2!*14!}\\=\frac{16*15*14!}{(2*1)*14!}\\=\frac{16*15}{2}\\=120[/tex]

The hypotenuse of the triangle would be the diameter of the semi circle.

Using the Pythagorean theorem you can find that.

8^2 + 6^2 = x^2

64 +36 = x^2

100 = x^2

x = √100

x = 10

The diameter is 10, now find the circumference.

Circumference = diameter x PI = 10 x 3.14 = 31.4

Since it is a semi circle, the circumference would be 1/2 of that.

31.4 / 2 = 15.7

The perimeter would be 8 + 6 + 15.7 = 29.7

Answer:

The volume of the cylinder is 63π or 197.9 units³

Step-by-step explanation:

* Lets revise how to find the volume of any cylinder

- The volume of the regular solid = area of the base × its height

- The cylinder has two circular bases

- The area of the circle = πr²

∴ The volume of the cylinder = πr² × its height

* Now lets take the dimensions of the cylinder from the problem

- The height of the cylinder is 7 units

- The radius of the cylinder is 3 units

∵ The volume of the cylinder = πr² × its height

∴ The volume = π × 3² × 7 = 63π = 197.9 units³

* The volume of the cylinder is 63π or 197.9 units³

Answer:

The volume of cylinder =197.82 units²

Step-by-step explanation:

Formula:-

Volume of cylinder =  πr²h

Where r - Radius of cylinder and

h - Height of cylinder

To find the volume of cylinder

Here r = 3 units and h = 7 units

Volume = πr²h

 = 3.14  * 3² * 7

 = 3.14 * 9 * 7

 = 197.82 units²

Therefore the volume of cylinder =197.82 units²

199.95 * 0.09 = 17.9955

when ever you want to work out a % just multiple it by the % in decimal ie 10% = 0.1, 100% = 1.0, 9% =0.09

OR

if you want to work out what 9% is added on top of the price to total 199.95 you can you this

A1= gross amount

B1 = tax percentage

(A1/(100+B1)*100) = 183.440367 before the tax is added so the total tax at 9% = 16.509633

Answer:

7

Let's solve your equation step-by-step.

5x−7+2−2x=−26

Step 1: Simplify both sides of the equation.

5x−7+2−2x=−26

5x+−7+2+−2x=−26

(5x+−2x)+(−7+2)=−26(Combine Like Terms)

3x+−5=−26

3x−5=−26

Step 2: Add 5 to both sides.

3x−5+5=−26+5

3x=−21

Step 3: Divide both sides by 3.

3x

x=−7

Answer:

x=−7

Answer:

the solution is x = -7

Step-by-step explanation:

Collect terms:

x(5 -2) +(-7 +2) = -26

3x -5 = -26

Add 5 to get the variable term by itself:

3x = -21

Divide by the coefficient of the variable:

x = -7

The answer to, "what is it?" is that it is a linear equation in x. After you collect terms, it is what is referred to as a "two-step" linear equation, because it takes two steps to solve it: add 5, divide by 3.

To simplify the expression −4(−11+4n)−3(−2n+9), you distribute the multiplication and then combine like terms to get the equivalent expression +17−10n.

The student has asked to simplify the expression −4(−11+4n)−3(−2n+9). To simplify this expression, we need to distribute the numbers outside the parentheses across the terms inside the parentheses. We'll do this step by step.

Now combine like terms:

So, the simplified equivalent expression is +17−10n.

the simplified and equivalent expression is 17 - 10n.

We need to simplify the expression:

[tex]-4(-11+4n)-3(-2n+9)[/tex]

To do this we need to open the brackets which gives us:

[tex]-4(-11+4n)-3(-2n+9) = 44 -16n + 6n -27[/tex]

Now we can solve the expression as follows:

[tex]-4(-11+4n)-3(-2n+9) = (44 - 27) + (-16n + 6n)\\\\ -4(-11+4n)-3(-2n+9) =17 - 10n[/tex]

So, the simplified and equivalent expression is 17 - 10n.

Answer:

(x + 3)(x + 7)

Step-by-step explanation:

Given

x² + 10x + 21

Consider the factors of the constant term (+ 21) which sum to give the coefficient of the x- term (+ 10)

The factors are + 3 and + 7, since

3 × 7 = 21 and 3 + 7 = 10, hence

x² + 10x + 21 = (x + 3)(x + 7)

Answer:

x = 8.5

L = 17

W = 6.5

Step-by-step explanation:

P = 2*(L + W)

W = x - 2

L = 2x

P = 47

47 = 2 * (2x + x - 2)

47 = 2 * (3x - 2)          Remove the brackets.

47 = 6x - 4                 Add 4 to both sides.

47 + 4 = 6x - 4+4       Combine

51 = 6x                       Divide by 6

6x/6=51/6                  Combine

x = 8 3/6 or 8.5

x = 8.5

========

L = 2*x

L = 2*8.5

L = 17

=====

W = x - 2

W = 8.5 - 2

W = 6.5

Answer:

x=8.5, length is 17, and width is 6.5

Step-by-step explanation:

To solve for x, you would add the two sides together, getting x-2+2x+3x-2. Now, you would multiply this figure by two, because you only have half of the perimeter as of now. (3x-2)*2+6x-4. Now, because the perimeter is 47, you have this equation

6x-4=47

Add four to both sides

6x=51

Divide by 6

x=51/6=8.5

Now, you would plug this into both of the other sides of the rectangle.

The length, or the longest side, measures 2x

2*8.5=17

The width, or the shorter side, measures x-2

8.5-2=6.5

Answer:

[tex]\frac{2\sqrt{2}}{\sqrt{3}-\sqrt{2}}=2\sqrt{6}+4[/tex]

Step-by-step explanation:

We have the expression:

[tex]\frac{2\sqrt{2}}{\sqrt{3}-\sqrt{2}}[/tex]

To simplify the expression multiply by the conjugate of the denominator.

The denominator is

[tex]\sqrt{3}-\sqrt{2}[/tex]

Then its conjugate is:

[tex]\sqrt{3}+\sqrt{2}[/tex]

Then:

[tex]\frac{2\sqrt{2}}{\sqrt{3}-\sqrt{2}}*\frac{\sqrt{3}+\sqrt{2}}{\sqrt{3}+\sqrt{2}}\\\\=\frac{2\sqrt{2}\sqrt{3}+2\sqrt{2}\sqrt{2}}{(\sqrt{3})^2-(\sqrt{2})^2}\\\\\frac{2\sqrt{6}+4}{3-2}}\\\\= \frac{2\sqrt{6}+4}{1}}=2\sqrt{6}+4[/tex]

Answer:

[tex]4+2\sqrt{6}[/tex]

Step-by-step explanation:

Given expression is [tex]\frac{2\sqrt{2}}{\sqrt{3}-\sqrt{2}}[/tex].

Now we need to simplify this. So multiply and divide by conjugate of denominator.

[tex]\frac{2\sqrt{2}}{\sqrt{3}-\sqrt{2}}[/tex]

[tex]=\frac{2\sqrt{2}}{\left(\sqrt{3}-\sqrt{2}\right)}[/tex]

[tex]=\frac{2\sqrt{2}}{\left(\sqrt{3}-\sqrt{2}\right)}\cdot\frac{\left(\sqrt{3}+\sqrt{2}\right)}{\left(\sqrt{3}+\sqrt{2}\right)}[/tex]

[tex]=\frac{2\sqrt{6}+2\sqrt{4}}{\left(\sqrt{3}\right)^2-\left(\sqrt{2}\right)^2}[/tex]

[tex]=\frac{2\sqrt{6}+2\cdot2}{3-2}[/tex]

[tex]=\frac{2\sqrt{6}+4}{1}[/tex]

[tex]=2\sqrt{6}+4[/tex]

[tex]=4+2\sqrt{6}[/tex]

Hence final answer is [tex]4+2\sqrt{6}[/tex].

1cm = 50

2 cm = 50 x 2

3cm = 50 x 3

and the inverse:50m = 50/50 = 1cm

100m = 100/50 = 2cm

150m = 150/50 = 3cm

381m = 381/
