Step-by-step explaunfere:
The circumference of a circle is the distance around the outside of the circle. The diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference.
1- C ≈ 50.27 in
2- C ≈ 31.42 in
3- A ≈ 201.06
4- A ≈ 314.16
5- C = 14π = 43.982 ≈ 44 inches
π (Pi) times the Radius squared: A = π r2
or, when you know the Diameter: A = (π/4) × D2
or, when you know the Circumference: A = C2 / 4π

Determine if the sequence is arithmetic or geometric, and find the common difference or ratio.
x 1 2 3 4
f(x) 5 −5 −15 −25
Arithmetic, common difference = −10
Arithmetic, common difference = −1
Geometric, common ratio = −10
Geometric, common ratio = −1
Answers
Answer:
The sequence is arithmetic with a common difference of -10
Step-by-step explanation:
From the question, we want to determine if the sequence is arithmetic or geometric
From the question
f(1) = 5
f(2) = -5
f(3) = -15
Mathematically for the common difference;
f(3) - f(2) = f(2) - f(1)
Since;
-15-(-5) = -5-5
-10 = -10
Since the common difference here is same , then the sequence is arithmetic with a common difference of -10

The length of a rectangle is twice the width. The area of the rectangle is 80 square units. Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square? Estimate the length and width of the rectangle.
Answers
Answer:
Width of the rectangle = 6.325 units
Length of the rectangle = 12.65 units
Side length of the square the 6.325 units.
Step-by-step explanation:
The length of a rectangle is twice the width. The area of the rectangle is 80 square units.
The area of the rectangle = Length × Width
Length = 2W
80 square units = 2W × W
80 = 2W²
W² = 80/2
W² = 40
W = √40
Width of the rectangle = 6.3245553203 units
Approximately = 6.325 units
Length = 2 × Width
= 2 × 6.325
= 12.65 units
• Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square?
We you divide a rectangle into 2 squares,
The length is divided into two.
Hence, the length of the rectangle = 12.65 units
12.65 units ÷ 2 = 6.325 units.
Hence, the side length of the square the 6.325 units.

1 pack of cigarettes contains 20 cigarettes. Each cigarette smoked is said to reduce a person's life expectancy by 11 minutes. If a person smoked one pack per day for 25 years, how much shorter would their life possibly be? In minutes: In days: In hours: In years: bruh, heaLP
Answers
Answer:
Step-by-step explanation:
1 pack per days means 20 cigarettes a days each cigarette reduces life by 11 minutes. which is 220mins per day
25*365*24*60 =13140000mins originally
1) 25 years in minutes will be
reduction of life due to smoking = 220*365*25= 2007500minutes
2)In days
originally = 9125days
after smoking=220/24*60=0.1527*365*25= 1393days are reduced
3)In hours
originally = 219000hrs
reduced life =3.67*365*25= 33488.75hrs

6 + 5 + 4 + 3 + 2 + 1 = 21Now the number of,
Rectangles and combinations are,
→ 1 rectangle = 6
→ 2 rectangles = 5
→ 3 rectangles = 4
→ 4 rectangles = 3
→ 5 rectangles = 2

What is the slope of a line parallel to the line whose equation is 5x+y=-9
Answers
Answer:
slope = - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
Given
5x + y = - 9 ( subtract 5x from both sides )
y = - 5x - 9 ← in slope- intercept form
with slope m = - 5
Parallel lines have equal slopes, thus
The slope of a parallel line to the given equation is m = - 5

Solve for H: A = L ⋅ W ⋅ H
H = A times W over L
H = W times L over A
H = L times A over W
H = A over quantity L times W
Answers
Answer:
The answer would be
H = A over L times W
Step-by-step explanation:
This is because, when you multiply the L, W, and H you end up getting A. This means that A is the biggest number. We automatically can tell that H is what were looking for so putting those two things together we have this: H = A over ???
The ??? would have to be L times W because those are the only things left and they get multiplied together which in the end leaves us with
H = A over L times w
aka
H=A/LxW

a) Angle XBC = 55⁰ because its correspond to Angle AXY which is equal to 55⁰ and corresponding angles are equal.
b)Angle BXC = 70⁰
Step-by-step explanation:
b) Since XB = XC, triangle BXC is therefore an isosceles triangle.
Angle XBC = Angle XCB
Sum of interior angles of a triangle = 180⁰
55⁰ + 55⁰ + Angle BXC = 180⁰
110⁰ + Angle BXC = 180⁰
Angle BXC = 180⁰- 110⁰
= 70⁰
What is the slope-intercept form of the linear equation 2x + 3y = 6? Drag and drop the appropriate number, symbol, or variable to each box
Answers
Answer:
y = -2/3x + 2
Step-by-step explanation:
2x + 3y = 6
To put it in slope intercept form, move x to the other side:
3y = -2x + 6
Divide each side by 3:
y = -2/3x + 2
So, y = -2/3x + 2 is the slope intercept form of the linear equation
