The Memphis Pyramid is in Tennessee is a building that is in the shape of a square pyramid. The base area of the building is 349,281 square feet and the height of the pyramid is 321 feet. If you were to roll a marble from the very top of the building, how many feet would it travel to reach the bottom? Round your answer to the nearest tenth.

Answers

Answer 1

Answer:

321.1 ft

Step-by-step explanation:

Linear Distance

Let's imagine a square-based pyramid of side L and height H. Please refer to the image provided below where a simplified drawing of the pyramid shows the diagonal distance D that the marble has to travel to reach the base of the pyramid from the very top of it, assuming it rolls by the very center of one of the sides.

The distance can be calculated by

[tex]\displaystyle D=\sqrt{\left(\frac{L}{2} \right)^2+H^2}[/tex]

We need to find the length of the side of the square base. We know its area is [tex]349,281 ft^2[/tex]. The area of a square is

[tex]A_s=L^2[/tex]

We solve for L

[tex]L=\sqrt{A}=\sqrt{349,281 }=18.9\ ft[/tex]

Now we compute D

[tex]\displaystyle D=\sqrt{\left(\frac{18.9}{2} \right)^2+321^2}[/tex]

[tex]\boxed{D=321.1\ ft}[/tex]

Evaluate the expression 1/3(4+18) -2 squared

Answers

Answer:

  Evaluate the expression 1/3(4+18) -2 squared

Step-by-step explanation:

First of all we will add brackets to understand the question as:

= ((1/3) * (4+18) - (2 squared))

= ((1/3) * ( 22) -  2² )

According to Math's rule that Multiplication and division must be completed before addition and subtraction.

=  (( 1/3 * 22) - 4 )

= (( 7.33) - 4 )

= ( 7.33 - 4 )

= 3.33

3.33 is the correct answer.

Let f(x) = (x^2+3x-5)/(x^2-8x+15) What is the domain of f(x) ?

Answers

Answer:

So, Domain = {set of all the real numbers except 3, 5}

Interval notation = {x ∈ set of all real numbers/ x ≠3 and x ≠ 5}

Step-by-step explanation:

The given function is f(x) = [tex]\frac{x^2 + 3x - 5}{x^2 - 8x + 15}[/tex]

Here we need to find the domain.

To find the domain, let's find the restricted domain.

If we set the denominator equal to zero and solve for x, we can find the restricted domain.

Here the denominator is [tex]x^2 -8x + 15 = 0[/tex]

Now we can factorize and solve for x.

(x - 3)(x - 5) = 0

(x - 3) or (x - 5) = 0

x -3 = 0  and x - 5 = 0

Solving the above equations, we get

x = 3 and x = 5

The restricted domains are x = 3 and x = 5.

Now we can find the domain.

Except 3 and 5, all the real numbers can be domain of this function.

So, Domain = {set of all the real numbers except 3, 5}

= {x ∈ set of all real numbers/ x ≠3 and x ≠ 5}.

Answer: all real numbers except 3, 5

Answer: p = +4

Step-by-step explanation: To solve this equation for p, our first step is to distribute the 3 through the parentheses on the left side.

3 times p is 3p and 3 times 2 is 6.

So we have 3p + 6 = 18.

Next, we need to isolate the p term by subtracting 6 from both sides of the equation to get 3p = 12.

Finally, we divide both sides of the equation by 3 to get p = +4.

It’s a statistics mathematical question

Answers

Answer: About 0.8034 of the items will be classified as good.

Step-by-step explanation:

Let's first understand that because 13% of the items are defective, that means 87% of the items are not defective. And because the inspector incorrectly classifies the items 9% of the time, it's important to understand that that means both the defective and the not defective items may be incorrectly classified. In order to figure out what proportion will be classified as 'good,' let's set up a tree diagram:

--0.13--defective

            |__0.09__ classified as 'good'

            |__0.91__ classified as 'defective'

--0.87--not defective

           |__0.09__ classified as 'defective'

           |__0.91__classified as 'good'

This chart essentially reiterates the information in the prompt, showing that 9% of each type of item will be incorrectly classified. Now we need to find the proportion of items that will be classified as 'good.' To do this, we must multiply the proportion of items classified as 'good' by the proportion of items that are either defective or not defective for both types, like this:

(0.13 * 0.09) + (0.87 * 0.91)

this expression in words means: "13% of the items will be classified as good 9% of the time, and the other 87% of the items will be classified as good 91% of the time"

When we multiply and add these numbers together, we get 0.8034, but you should round to 2 or 3 decimal places like the prompt instructs. Hope this helped! :)

Kevin and Marcus were comparing their ages. The same of their ages was at least 9 years but was at most 24 years. If Kevin is 6 years old, which of the following inequalities represents all possible values for Marcus age, m?

Answers

The inequality that represent age of marcus is:

[tex]24\geq 6+m\geq 9[/tex]

The possible values for age of Marcus is:

m = 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18

Solution:

Given that,

The sum of ages of Kevin and Marcus was at least 9 years but was at most 24 years

Kevin is 6 years old

Let "m" be the age of Marcus

Thus we frame a inequality as:

[tex]24\geq \text{ sum of ages } \geq 9[/tex]

at least 9 years means that "greater than or equal to 9"

at most 24 years means "less than or equal to" 24

From given,

Sum of ages = kevin age + marcus age

Sum of ages = 6 + m

Thus the inequality is:

[tex]24\geq 6+m\geq 9[/tex]

Solve the inequality

[tex]\mathrm{If}\:a\ge \:u\ge \:b\:\mathrm{then}\:a\ge \:u\quad \mathrm{and}\quad \:u\ge \:b\\\\24\ge \:6+m\quad \mathrm{and}\quad \:6+m\ge \:9\\\\Solve\ them\ separately[/tex]

[tex]24\ge \:6+m\\\\\mathrm{Switch\:sides}\\\\6+m\le \:24\\\\\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}\\\\6+m-6\le \:24-6\\\\\mathrm{Simplify}\\\\m\le \:18[/tex]

Now solve another inequality

[tex]6+m\ge \:9\\\\\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}\\\\6+m-6\ge \:9-6\\\\\mathrm{Simplify}\\\\m\ge \:3\\\\\mathrm{Combine\:the\:intervals}\\\\m\le \:18\quad \mathrm{and}\quad \:m\ge \:3\\\\\mathrm{Merge\:Overlapping\:Intervals}\\\\3\le \:m\le \:18[/tex]

Thus possible values for age of Marcus is:

Circumference of a circle is simply the length of the boundary of the circle which can be measured by the formula of [tex]2\pi r[/tex]

In the figure B the given radius in the figure is 5

Putting 5 in the formula to find the circumference of the circle gives

3 3x = 7
4 x = 7 over 3


Which of the following has all of the correct justifications Kelsey used to solve this equation?

Answers

The correct justifications Kelsey used to solve this equation is:

1. distributive property

2. combine like terms

3. addition property of equality

4. division property of equality

Solution:

Given that,

Kelsey solved the following equation:

[tex]7x - \frac{1}{2}(8x+2) = 6[/tex]

Step 1:

By distributive property,

a(b + c) = ab + bc

Therefore,

[tex]7x - (\frac{1}{2} \times 8x)+( \frac{-1}{2} \times 2)= 6\\\\7x - 4x - 1 = 6[/tex]

Step 2:

Combine the like terms

7x - 4x - 1 = 6

3x - 1 = 6

Step 3:

Addition property of equality

The property means that when we add the same number to both sides of an equation, the sides remain equal

3x - 1 = 6

Add 1 on both sides

3x - 1 + 1 = 6 + 1

3x = 7

Step 4:

Division property of equality

The Division Property of Equality means that when we divide both sides of an equation by the same non zero number, the sides remain equal

3x = 7

Divide both sides by 3

[tex]\frac{3x}{3} = \frac{7}{3}\\\\x = \frac{7}{3}[/tex]

Thus the correct justifications Kelsey used to solve this equation is:

1. distributive property. 2. combine like terms. 3. addition property of equality. 4. division property of equality

Answer:

I took the test it is  1. Distributive property 2. Combine like terms 3. Addition property of equality 4. Division property of equality
