A regular octagonal pyramid. Each side of the base is 6 cm long. it has a height of 10cm. Find the surface area of the pyramid
Answers
9514 1404 393
Answer:
470.16 cm²
Step-by-step explanation:
The apothem of the base is used for two purposes: to find the area of the base, and to find the slant height of each face.
The apothem of the base for side length s is ...
s/2 = a·tan(π/8)
a = s/(2·tan(π/8)) ≈ 7.24 cm
The slant height of a triangular face is found using the Pythagorean theorem. The apothem of the base and the height are legs of the right triangle whose hypotenuse is the slant height. For slant height x, we have ...
x² = 10² + a² = 100 +52.46
x ≈ √152.46 ≈ 12.35
__
The area of the 8 triangular faces will be ...
A = 1/2Px . . . . where P is the perimeter of the pyramid
The area of the base will be ...
A = 1/2Pa
So, the total surface area is ...
A = 1/2P(a + x) = (1/2)(8)(6 cm)(7.24 +12.35 cm) ≈ 470.16 cm²
The answer is 470.16 cm²

x+y=180
x=10y+48
(With Steps Plz)
Answers
Answer:
(168,12)
Step-by-step explanation:
Substitute x = 10y+48 in the first equation.
[tex]10y + 48 + y = 180 \\ 11y = 180 - 48 \\ 11y = 132 \\ y = \frac{132}{11} \\ y = 12[/tex]
We have got the y-value. Our next goal is to find the x-value by substituting y-value in any given equations.
For me, I will be substituting y = 12 in the first equation.
[tex]x + 12 = 180 \\ x = 180 - 12 \\ x = 168[/tex]
Answer Check
Substitute both x-value and y-value in both equations.
[tex]168 + 12 = 180 \\ 180 = 180[/tex]
Our first equation is true for both values.
[tex]168 = 10(12) + 48 \\ 168 = 120 + 48 \\ 168 = 168[/tex]
Our second equation is true for both values.
Thus, the answer is (168, 12)

It costs $1480 to enclose an 80' by 80' rectangular area.
Answers
Answer:
It costs $560 to enclose a 50' by 40' rectangular area.
Step-by-step explanation:
50 + 40 = 90
90 x 4 = 360 because of the $4 per foot
360 + 200 = 560, you add 200 because of the flat rate charge.

Answers
Answer: 61
Step-by-step explanation: My Teacher told me is Right
The number of the 9-centimeter long tape will be 61. The correct option is C.
What is division?Discovering the maximum number of equal pieces that can be made by splitting an integer into equal parts.
One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division. The other operations are multiplication, addition, and subtraction.
Given that Justin has a roll of tape 549 centimeters long. he cuts the tape into pieces that are 9 centimeters long.
The number of 9 centimeters tapes will be calculated as below:-
Number = 549 / 9
Number = 61
Therefore, the number of the 9-centimeter long tape will be 61. The correct option is C.

The function f(x)f(x) is a quadratic function and the zeros of f(x)f(x) are 11 and 55. The y-intercept of f(x)f(x) is 2020. Write the equation of the quadratic polynomial in standard form.
Answers
Answer: [tex]4x^2 -24x+20[/tex]
Step-by-step explanation:
If p and q are zeroes of f(x), then f(x) = k (x-p)(x-q) , where k is a constant.
Given: The function f(x)f(x) is a quadratic function and the zeros of f(x)f(x) are 1 and 5.
f(x) = k (x-1)(x-5)
y-intercept = Value of function at x=0
So, y-intercept = k (0-1)(0-5)= 5k
Since, y-intercept of f(x) = 20
so, 5k = 20
⇒ k= 4
Quadratic polynomial [tex]= 4(x-1)(x-5)[/tex]
[tex]=4(x^2-6x+5)\\\\= 4x^2 -24x+20[/tex]
Hence, the equation of the quadratic polynomial in standard form =[tex]4x^2 -24x+20[/tex]

Brainly annie has 2 bags of apples and 5 single apples eva has 1 bag of apples and 11 single apples they have the same amount of apples how many apples so they have in total
Answers
Answer:
34 apples
Step-by-step explanation:
To answer: try setting up each of the equations for Annie and Eva.
Annie: 2(bag) + 5
Eva: 1(bag) + 11
Those two equations equal each other. So set that up:
2(bag) + 5 = 1(bag) + 11
Now solve for the size of the bag.
2(bag) - 1(bag) = 11 - 5
1(bag) = 6 apples
Now substitute 6 back into either equation to determine number of apples.
Annie: 2(6) + 5 = 12+5=17
They each have 17, so there are 34 apples in total.

Sinister Stan stole 3 3/4 oz of slime from Messy Molly, but his evil plans require 6 3/8 oz of slime. He stole another 2 3/5 oz of slime from Rude Ralph. How much more slime does Sinister Stan need for his evil plan?
Answers
Answer: 1/40
Step-by-step explanation:
Since we are told that Sinister Stan stole 3 3/4 oz of slime from Messy Molly and stole another 2 3/5 oz of slime from Rude Ralph. The total oz of slime stole would be:
= 3 3/4 + 2 3/5
= 3 15/20 + 2 12/20
= 5 27/20
= 6 7/20
We are told that his evil plans require 6 3/8 oz of slime, the amount needed for Sinister Stan for his evil plan would be:
= 6 3/8 - 6 7/20
= 6 30/80 - 6 28/80
= 2/80
= 1/40
