Raymond needs to cover the entire surface area of the square based pyramid with paper what is the minimum amount of paper he will need

Complete Question:

A pedestal for a statue is made with 405 cubic feet of concrete. A rectangular prism with a height of 9 feet.

What is the area of the base of the pedestal?

Answer:

45 square feet

Step-by-step explanation:

Given the following data;

Volume of pedestal = 405 ft³

Height of rectangular prism = 9 ft

To find the area of the base of the pedestal;

Volume of pedestal = base area * height

405 = base area * 9

Base area = 405/9

Base area = 45 square feet.

Therefore, the area of the base of the pedestal is 45 square feet.

Answer:

45 square feet

Answer:

(43[tex]x^{2}[/tex] - 26x) [tex]ft^{2}[/tex]

Step-by-step explanation:

Area of the yard that is not pat of the sandbox = Area of the yard - Area of the sandbox

Since both the yard and the sandbox has a rectangular shape, then;

Area of a rectangle = length x width

So that,

Area of the yard = length x width

                            = (6x+7) x 8x

                            = (48[tex]x^{2}[/tex] + 56x) [tex]ft^{2}[/tex]

Area of the sandbox = length x width

                                  = (x+6) x 5x

                                  = (5[tex]x^{2}[/tex] + 30x) [tex]ft^{2}[/tex]

Thus,

Area of the yard that is not pat of the sandbox = (48[tex]x^{2}[/tex] + 56x) - (5[tex]x^{2}[/tex] + 30x)

                                = 48[tex]x^{2}[/tex] + 56x - 5[tex]x^{2}[/tex] - 30x

                                = (43[tex]x^{2}[/tex] - 26x) [tex]ft^{2}[/tex]

Area of the yard that is not pat of the sandbox is (43[tex]x^{2}[/tex] - 26x) [tex]ft^{2}[/tex].

Answer:

∠G

Step-by-step explanation:

The tangent of an angle is given by the following trigonometric ratio;

[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent \ leg \ length}[/tex]

From the question, we have;

tan ∠K = 6/8

ΔGIH is similar to ΔKJL

By observation of the length, we have;

Segment HI and segment JL are corresponding segments

Segment KL and segment HG are corresponding segments

∴ ∠K and ∠G are corresponding angles

∴ tan∠G = tan∠K = 6/8

The angle whose tangent is 6/8 is ∠G

Answer:

  (a, b, c) = (-0.425595, 11.7321, 2.16667)

  f(x) = -0.425595x² +11.7321x +2.16667

  f(1) ≈ 13.5

Step-by-step explanation:

A suitable tool makes short work of this. Most spreadsheets and graphing calculators will do quadratic regression. All you have to do is enter the data and make use of the appropriate built-in functions.

Desmos will do least-squares fitting of almost any function you want to use as a model. It tells you ...

  a = -0.425595

  b = 11.7321

  c = 2.16667

so

  f(x) = -0.425595x² +11.7321x +2.16667

and f(1) ≈ 13.5

Additional comment

Note that a quadratic function doesn't model the data very well if you're trying to extrapolate to times outside the original domain.

Answer:

25.6125

Step-by-step explanation:

since 25 is a whole number, it'd be 25.ˣˣˣˣ

now all you have to do it divide the fraction so 49 ÷ 80 =  0.6125

last step is to add ⇒ 25 + 0.6125 = 25.6125

Step-by-step explanation:

Given;

[tex]a = 2\\ h = 4\\ b=7[/tex]

See attachment for trapezium

The area

From the attachment, the formula is:

[tex]Area = \frac{1}{2} * (a + b) * h[/tex]

[tex]Area = \frac{1}{2} * (2 + 7) * 4[/tex]

[tex]Area = \frac{1}{2} * 9 * 4[/tex]

Answer:

C = $1.50x + $3y

Step-by-step explanation:

Using the information provided we can create an equation to model the total dollar cost of Amanda's purchase when visiting the candy store. To do this we need to multiply each candies individiual cost by the amount of each candy they are purchasing. Then we add together all of these values to get the final total cost which would be represented by C.

C = $1.50x + $3y

Answer:

The expression is 9(n + 8) - 6, the value is 111 ⇒ answer A plz mark me brainlest

Step-by-step explanation:

* Lets explain how to solve the problem

- We have a statement:

" six less than nine times the sum of a number and eight"

- When we solve we will start by the last part

- The last part is the sum of a number and 8

- Assume that the number is n

∵ The sum is the answer of adding

∴ The sum of a number and eight is ⇒ n + 8

- Nine times the sum

∵ The sum is n + 8

∵ Nine times means multiply the sum by 9

∴ Nine times the sum is ⇒ 9(n + 8)

- Six less than nine times the sum

∵ Nine times the sum is 9(n + 8)

∵ Six less than means subtract 6 from nine times the sum

∴ Six less than nine times the sum is ⇒ 9(n + 9) - 6

* The expression is 9(n + 8) - 6

- Lets evaluate the expression when n = 5

∵ 9(n + 8) - 6

∵ n = 5

∴ The value = 9(5 + 8) - 6

∴ The value = 9(13) - 6

∴ The value = 117 - 6

∴ The value = 111

* When n = 5 the value of the expression is 111

Step-by-step explanation:

Answer:

angle NKP = 60 degrees

Step-by-step explanation:

A line will always equal 180 degrees

If angle JKM and angle MKN are complentary, that means they will add up to 90. Since angle JKM is 40 degrees, angle MKN must be 50 degrees

Angle LKP is 30 degrees

Form an equation:

180 = 40 + 50 + 30 + angle NKP

Combine like terms

180 = 120 + angle NKP

Subtract 120 from both sides to isolate the unknown angle

60 = angle NKP

Answer:

18

Step-by-step explanation:

180X10=1800

1800/100=18
