How is proportional reasoning used to interpret distances on maps?
Answer:
It shows how a dimension in a scale drawing is related to the actual object. A map is a scale drawing. The measurements on a map are in proportion to the actual distances. If 1 inch on a map equals an actual distance of 2 miles, the scale is 1 inch = 2 miles

Square root of 2/x time square root of x^2/8
Answer:
A.
[tex] \sqrt{x } \div 2[/tex]
is the answer
The choice which is equivalent to [tex]\sqrt{\frac{2}{x}}\cdot\sqrt{\frac{x^2}{8}}[/tex] is given by (A) [tex]\frac{\sqrt{x}}{2}[/tex].
What is expression?Expression is a mathematical term that involves variables, numbers and other mathematical quantities and operations or combinations of them.
The given expression is [tex]\sqrt{\frac{2}{x}}\cdot\sqrt{\frac{x^2}{8}}[/tex]
Calculating the expression we get,

Unit 1 : Algebra basics Homework 1: the real numbers
Real numbers may be explained as all set of numbers which may be used for counting, fractions or decimals. Real numbers may be any set of natural, whole, integer, rational or irrational numbers.
• NATURAL NUMBERS which are all set of positive whole numbers from 1. Examples : (1, 3, 5, 8, 100)
• WHOLE NUMBER are set of all natural numbers .while numbers also include the value value (0, 1, 200, 500) are whole numbers
• INTEGERS : include all positive and negative natural or whole number values. They include (-1, - 10, 10, 5)
• RATIONAL numbers are real numbers which can be expressed in the form m/n where both m and n are integer values and the denominator, n ≠ 0 Examples : (1/2, 0.9, 10/1, √4, 3.5)
• IRRATIONAL numbers are real numbers which are not integer values and cannot be expressed in the form m/n Non-terminating and non-repeating decimal numbers are IRRATIONAL numbers. (√3, 1.43136..., 1.4141..., π)

hmmm.
the other answer says the volume of a wedge is
4/9 × pi×r³
but I read here only
4/9 × pi³
so, what is correct ?
if I assume my reading is correct, then the solution is actually
4/9 × pi×r³ = 4/9 × pi³
pi×r³ = pi³
r³ = pi²
[tex]r = \sqrt[3]{ {\pi}^{2} } [/tex]
and that would mean

2 Jessica re the same number of books each month. Write an expression to represent
the number of books Jessica reads in 2 years.
Answer:
The answer is Jessica reads 24b books in 2 years where b is the number of books she reads each month.
Step-by-step explanation:
First, decide on your variable. You don't know how many books Jessica reads each month, but you know every month it is the same.
Let b equal the number of books Jessica reads each month.
Next, write a variable expression using b. In one month Jessica reads b books. In 2 months Jessica reads 2b books. The question asks for an expression that represents the total number of books Jessica reads in 2 years. There are 12 months in a year so there are 24 months in 2 years. So your expression is

The length of a rectangle is 2x + 4 and the width is x + 8. If the perimeter of the rectangle is 96, use the value of x to find the length and width of the rectangle.
Hey there! I'm happy to help!
The formula for the perimeter of a rectangle is 2L+2W=P where W is the width and L is the length. This is because we have our two sides that are lengths and our two sides that are widths (different values) and we add them together to see what the distance around the whole rectangle is.
So, let's insert these values into the equation.
2(2x+4)+2(x+8)=96
We use the distributive property to remove the parentheses (which is us multiplying our equations for length and width by two).
4x+8+2x+16=96
We combine the like terms.
6x+24=96
We subtract 24 from both sides.
6x=72
Divide both sides by 6.
x=12
Now that we have our value of x, we can plug it into our length and width equations to find those values.
LENGTH:
2x+4
2(12)+4
24+4
28
WIDTH:
x+8
12+8
20
So, our length is 28 and our width is 20.

Answer:
m∠b = 43°
Step-by-step explanation:
The image shown shows vertical angles. By the definition of vertical angles, quote:
"Angles opposite of each other when two lines cross are always equal", therefore, if one of the vertical angles is 43°, that implies that m∠b = 43°, by definition of vertical angles.

What is graph transformation?
The technique of altering an existing graph or graphed equation to create a different version of the following graph is known as graph transformation. In particular, the change of algebraic equations, it is a typical kind of algebraic problem.
Graphs can be extended, rotated, inverted, or any combination of these transformations; they can also be translated or moved along the xyxy plane. The formulas "move the function f(x)f(x) by cc units in some direction," "stretch the function f(x)f(x) by cc units," and "rotate the function f(x)f(x) by xx units about the xx-, yy-, or zz-axis" are frequently used in mathematical issues. In every instance, the transformation has specific, calculable effects on the underlying function.
Since the triangle ABC and DEF is similar
So we can write,
DE/BC=EF/AB=FD/CA
scale factor =Length of CA/length of DF

You are going to have a swimming pool put your back yard this summer. The dimensions of the pool are going to be 15 ft by 30 ft. There is going to be a concrete walkway around the outside of the pool, but they are not sure how wide it will be. The design of the pool, including the walkway, is shown below.
The perimeter of a shape is the sum of the all visible side lengths of the shape. The perimeter of the pool including the walkway is 90 + 8x
Given that:
[tex]Length = 15[/tex]
[tex]Width = 30[/tex]
Let the width of the walkway be x.
The dimension of the pool including the walkway is calculated by adding the dimension of the pool to the width of the walkway (on both sides):
So, we have:
[tex]Length = 15 + x + x[/tex]
[tex]Length = 15 + 2x[/tex]
[tex]Width = 30 + x + x[/tex]
[tex]Width = 30 + 2x[/tex]
The perimeter (P) of the walkway is then calculated using:
[tex]P = 2 \times (Length + Width)[/tex]
This gives:
[tex]P = 2 \times (15 + 2x + 30 + 2x)[/tex]
Collect like terms
[tex]P = 2 \times (15 + 30+ 2x + 2x)[/tex]
[tex]P = 2 \times (45+ 4x)[/tex]
Open brackets
[tex]P = 2 \times 45+ 2 \times 4x[/tex]
[tex]P = 90+ 8x[/tex]
Hence, the perimeter of the pool including the walkway is 90 + 8x (see attachment)
