The length of the apothem of the regular octagon will be equal to 1.75 cm
What is a regular octagon?The regular octagon is the shape made up of the 8 sides or also the combination of the 8 isosceles triangles connected together side by side.
Here it is given:
Area of the Octagon = [tex]10.15\ cm^2[/tex]
The side of the octagon=1.45 cm
As we know that the octagon consists of the 8 isosceles triangles so the area of one triangle will be
[tex]= \dfrac{10.15}{8} =1.27\ cm^2[/tex]
Now the area of the isosceles triangle is given as:
[tex]A=\dfrac{1}{2} \times h\times b[/tex]
[tex]1.27=\dfrac{1}{2} \times h\times 1.45[/tex]
[tex]h=1.75\ cm[/tex]
Thus the length of the apothem of the regular octagon will be equal to 1.75 cm

What is the distance between points A and B? A number line going from negative 8 to positive 8. A closed circle appears at negative 5 and is labeled A. A closed circle appears at positive 1 and is labeled B. An orange arrow line extends the length of the number line and contains points A and B. Units units 5 units 6 units
Answer:
6 unitsStep-by-step explanation:
Since the point A that is enclosed in the circle is on negative 5 (i.e -5 ) and point B appears to be located on positive 1 (i.e +1), hence the distance between points A and B is expressed as B - A
BA = A-B
Given
B = -5
A = +1
BA = 1-(-5)
BA = 1+5
BA = 6units
Hence the distance between points A and B is 6units
Answer:
option d: 6 units

the perimeter of a square piece of cardboard is 56 inches. how long is each side of the piece of cardboard ? PLEASE ANSWER ASAP
Answer:
14 inches
Step-by-step explanation:
To calculate the area of a square, multiply the base by itself, which can be expressed as side × side. If a square has a base of length 8 inches its area will be 8 × 8= 64 square inches. Area of a square is given by: A = a2. where a = length of side. Perimeter of a square = 4a.

Step-by-step explanation:
He added and subtracted the denominators. When adding/subtracting fractions, you need common denominator. Then you would only add/subtract the numerators.
So to solve it correctly, you would first find the common denominator, which for part a, it would be 3x5=15. Then rewrite both fractions s.t. 5/15 + 9/15
Then add the numerator. So 14/15

Balance of trade is the difference that is between the value of a country's exports and the value of its imports.
What is a balance of trade?
Your information is incomplete. Therefore, an overview will be given. The balance of trade or net exports, is the difference between the monetary value of a nation's exports and imports over a period.
The balance of Trade formula = Country's Exports – Country's Imports.
For example, suppose the USA imported $1.8 trillion but exported $1.2 trillion to other countries, then the USA had a trade balance of -$600 billion.

The perimeter of a rectangular room is 32m.The length of a diagonal is 8m more than than the width.Find the dimensions of the room.
Answer: 12m by 4m.
Step-by-step explanation: You are looking for the dimensions of the room here, also known as the length and width.
Let’s make width equal to x since we don’t know what the value is. Length is going to be x + 8 since the diagonal is 8m MORE than the width.
w = x
l = x + 8
Use the equation for the perimeter.
P = 2l + 2w
Plug in your values:
32 = 2(x + 8) + 2(x)
Now, solve for x! First start by distributing the 2:
32 = 2x + 16 + 2x
Next, add like terms:
32 = 4x + 16
Subtract 16 from both sides:
16 = 4x
Divide by 4 on both sides:
4 = x
Now we have x, but remember, x is equal to the width. We just solved for width so now we need length.
l = x + 8
Plug in your x and solve:
l = 4 + 8
l = 12
Your length is 12m and your width is 4m, therefore, the dimensions of the rectangular room are 12m by 4m.
If Line Overline BC Is The Diameter Of The Circle Below,What is The area of the circle
The area of the circle of diameter BC is the amount of space on the circle
Using the assumed value, the area of the circle is 19.625
How to determine the areaThe circle is not given.
So, I will assume a value for length BC
Assume the length of BC is:
BC = 5
The area of the circle would be:
[tex]Area = \pi (\frac{BC}{2})^2[/tex]
So, we have:
[tex]Area = 3.14 * (\frac{5}{2})^2[/tex]
Evaluate the product
[tex]Area = 19.625[/tex]
Using the assumed value, the area of the circle is 19.625

(7x10^5)x(3x10^2) in standard form
Answer:
2.1 x 10^8
Step-by-step explanation:
The expression (7x10⁵)x(3x10²) in the standard form will be 2.1 x 10⁸.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is (7x10⁵)x(3x10²). The standard form of the expressions can be written as,
E = (7x10⁵)x(3x10²)
E = ( 7 x 3 ) x ( 10⁵⁺²)
E = 21 x 10⁷
E = 2.1 x 10⁸
Hence, the standard form is 2.1 x 10⁸.
