What is the area of a regular pentagon with an 8-cm
apothem and 11.6-cm sides?
✓
Sub
Answer:
232.5 cm²
Step-by-step explanation:
232.5
The required area of the regular pentagon with an 8-cm apothem and 11.6-cm sides is 232 cm².
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
To find the area of a regular pentagon, we can use the formula:
Area = (1/2) x Apothem x Perimeter
where Apothem is the distance from the center of the pentagon to the midpoint of any side, and Perimeter is the sum of the lengths of all the sides.
In this case, the apothem is given as 8 cm, and the length of each side is given as 11.6 cm.
To find the perimeter, we can simply multiply the length of one side by 5:
Perimeter = 5 x 11.6 cm = 58 cm
Now, we can plug in these values into the formula:
Area = (1/2) x 8 cm x 58 cm
Area = 232 cm²
Therefore, the area of the regular pentagon with an 8-cm apothem and 11.6-cm sides is 232 cm².

A system consists of two components A and B that operate independently. The system
fails when either component fails. The probability that component A fails is 0.2, and
the probability that component B fails is 0.1. What is the probability that the system
fails?
Answer:
0.3
Step-by-step explanation:
When one component fails, so does the other one.
a + b = P
0.1 + 0.2 = 0.3
Your answer would be 0.3 or 30%.

Which ordered pair does NOT lie on the graph of the exponential function
f(x) = 3(1/4)^x
A. (12, 0)
B. (-2, 48)
C. (2, 3/16)
D. (0, 3)
I labeled them all on Desmos & they all seem to lie on it, which is why I need help.
The ordered pair does not lie on the graph of the exponential function
is (12, 0).
Option A is the answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To check whether an ordered pair lies on the graph of the exponential function f(x) = [tex]3(1/4)^x,[/tex]
We need to substitute the values of x and y into the function and see if the equation holds true.
A. (12, 0)
Substituting x = 12 and y = 0 into the function, we get:
[tex]f(12) = 3(1/4)^{12} = 0.000002861[/tex]
This does not equal y = 0, so (12, 0) does not lie on the graph of the function.
B. (-2, 48)
Substituting x = -2 and y = 48 into the function, we get:
[tex]f(-2) = 3(1/4)^{-2} = 48[/tex]
This does not equal y = 48, so (-2, 48) does lie on the graph of the function.
C. (2, 3/16)
Substituting x = 2 and y = 3/16 into the function, we get:
[tex]f(2) = 3(1/4)^2 = 3/16[/tex]
This equals y = 3/16, so (2, 3/16) does lie on the graph of the function.
D. (0, 3)
Substituting x = 0 and y = 3 into the function, we get:
[tex]f(0) = 3(1/4)^0 = 3[/tex]
This equals y = 3, so (0, 3) does lie on the graph of the function.
Therefore,
The ordered pair does not lie on the graph of the exponential function
is (12, 0).

What is 8/11 divided by 4
Answer:
2/11 or
0.181818
Step-by-step explanation:
Because 8/11 in precent form is 72%
So, 72÷4= 18.
If you put 18 in decimal form, it will be:
.18
For the fraction answer, .18 will be 0.22
And 0.22 in fraction form will be 2/11.
So those are your answers.
I hope this helped :)
The division of the equation A = ( 8/11 ) / 4 is A = 0.1818..
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the first fraction be represented as p = ( 8/11 )
Let the second fraction be q = 4/1
Now , the equation is A = 8/11 divided by 4
On simplifying , we get
A = ( 8/11 ) / 4
A = ( 8/44 )
A = 0.181818181..
Therefore , the value of A is a recurring decimal number
Hence , the equation is A = 0.181818..

Step-by-step explanation:
The volume (V) of water in the tank is calculated as
V = lbh (l is length, b is breadth and h is height )
Here l = 80, b = 40 and h = 50 , then
V = 80 × 40 × 50 = 160000 cm³
V ( in litres) = 160000 ÷ 1000 = 160 litres , then
number of times = 160 ÷ 10 = 16
