Length of the Circumference
Given a circle of radius r, the length of the circumference, or line surrounding the shape is:
The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:
r=7,917.5/2=3,958.75 miles
Assuming a plane flies around the equator at ground level, the distance it would travel is:
L = 24,873.6 miles

3.(x + 2) + (2x + 3) = 23
Answers
Answer:
x = 6
Step-by-step explanation:
(x + 2) + (2x + 3) = 23
Combine like terms
3x +5 = 23
Subtract 5 from each side
3x+5-5 = 23-5
3x = 18
Divide each side by 3
3x/3 = 18/3
x = 6
Answer:
x = 6
Step-by-step explanation:
1. Remove parentheses where unneeded. x + 2 + 2x + 3 = 23
2. Add constants. x + 5 + 2x = 23
3. Combine like terms. 3x + 5 = 23
4. Subtract "5" from the constants on both sides of the equation. 3x = 18
5. Divide both sides by 3. 3x/3 = 18/3
6. Simplify. x = 6

Given: Figure
To find: Number of 8.5 in. × 11 in. pieces used to cover the floors of a room and a hallway in her dollhouse
Solution:
In the given figure, AC = 22 in.
AB + BC = 22 in.
AB + EF = 22 (As BC = EF being opposite sides of rectangle)
AB + 10 = 22
AB = 22 - 10 = 12 in.
Area of rectangle ABGH = AB × AH = 12 × 5 = 60 square inches
(area of rectangle = length × breadth )
CE = CD + DE = AH + GF (As CD = AH and DE = GF)
CE = 5 + 15 = 20 inches
Area of rectangle BCEF = BC × CE = 10 × 20 = 200 square inches
(BC = EF = 10 in.)
Total area of the figure = Area of rectangle ABGH + Area of rectangle BCEF = 60 + 200 = 260 square inches
Area of pieces of felt = 8.5 × 11
So,
Number of pieces required = Total area of the figure / Area of pieces of felt = 3 pieces

A phone company charges $67 for monthly access and $14 for each gigabyte of data used. If you sign a two-year contract and use 147.5 gigabytes of data, what is the total amount you will pay for phone service?
Answers
Answer:
the answer is below :)
Step-by-step explanation:
BigBytes will be 100 +10x = y ($100 flat fee plus 10 times the number of gigabytes equals total cost).
GoGig will be 120 + 5x = y. ($120 flat fee plus 5 times the number of gigabytes equals total cost).
Now set them equal to each other and solve for x to find where the gigabytes are the same.
100 + 10x = 120 + 5x
Subtract 100 from both sides: 10x = 20 + 5x
Subtract 5x from both sides: 5x = 20.
Divide both sides by 5: x = 4. 4 gigabytes is the answer.
a brainliest would be appreciated :)
The total amount you will pay for phone service is 4 gigabytes.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
BigBytes will be 100 +10x = y
Therefore , We have $100 flat fee plus 10 times the number of gigabytes equals total cost).
GoGig will be 120 + 5x = y.
We have $120 flat fee plus 5 times the number of gigabytes equals total cost).
Now set them equal to each other and solve for x;
100 + 10x = 120 + 5x
Now Subtract 100 from both sides:
10x = 20 + 5x
Then Subtract 5x from both sides:
5x = 20.
Now Divide both sides by 5:
x = 4.
Hence, the total amount you will pay for phone service is 4 gigabytes.

Formula of area
AREA = LENGTH (multiply) BREATH
Answer:
The area of a triangle can be calculated with the formula: 1/2(bh), where b is the base length, and h is the height.
In this case, 4 is the base, and 7 is the height.
So we have: Area = 1/2(4)(7)
Simplifying: Area = 2(7), Area = 14.
The area of the triangle is 14 meters squared.
