What is the value of x? (Figures not drawn to scale.)
Answer:
x=1

this is because in this scale drawing they x2 when they are changing the numbers so you have to think what number x2 would give you 8 and that number is 1. so then you test it out and apply it to your scale drawing and they are 20 and 8

Can yall give me 4 examples of rules of exponents with answers pls?
Answer and Step-by-step explanation:
When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:
[tex]a^{x} * a^{y} = a^{x+y}[/tex]
When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:
[tex]a^{x} / a^{y} = a^{x-y}[/tex]
When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:
[tex](a^{x)^{y} } = a^{xy}[/tex]
When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:
[tex](ab)^{x} = a^{x} b^{x}[/tex]

Bicycle Rental Costs

1 $8
2 $16
3 $24
Show your work.
Answer:
[tex]\displaystyle y=8x[/tex]
Step-by-step explanation:
We are given a table and we want to determine a linear equation (in slope-intercept form) that represents this table.
So, we will first need to determine the slope. We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x₁, y₁) and (x₂, y₂) are two points.
We have three points: (1, 8), (2, 16), and (3, 24).
Let’s pick two. We can use (1, 8) and (2, 16).
So, let (1, 8) be (x₁, y₁) and let (2, 16) be (x₂, y₂). Substitute appropriately:
[tex]\displaystyle m=\frac{16-8}{2-1}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{8}{1}=8[/tex]
So, our slope is 8.
Now, we can determine the equation using point-slope form:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
Where m is our slope and (x₁, y₁) is a point.
We know that the slope is 8, so we will substitute 8 for m.
We can use any of our three points for the point. Let’s use (1, 8) for consistency. So, let (1, 8) be (x₁, y₁). Substitute appropriately:
[tex]\displaystyle y-8=8(x-1)[/tex]
Solve for y. Distribute the right:
[tex]\displaystyle y-8=8x-8[/tex]
Add 8 to both sides:
[tex]\displaystyle y=8x[/tex]
And we have our equation.
Notice that this is a direct variation or proportional equation as we don’t have a y-intercept.

Which partial quotients could be added to find 396 ➗ 12?
A 20 and 8
B 20 and 4
C 30 and 3
D 30 and 8
Answer:
divide 396 by 12 & you will get 396/12= 33
Step-by-step explanation:
When one number is divided by another number, the result is the quotient
So I think C) 30 and 3 is the best answer :))
The partial quotient of 396 ÷ 12 is 30 and 3.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
396 ÷ 12
12 x 33 = 396
33 is the quotient.
A partial quotient of 33 can be.
30 and 3.
Thus,
30 and 3 are the partial quotient.

Explain the process of solving inequality with variables on both sides. Show an example.
Answer:
Inequalities work exactly like equations with one exception. The process begins just like equations: first, do the opposite of what you see, then do the same thing on the other side of the sign. At the last step of solving an inequality, if you multiply or divide by a negative number, then you reverse the sign
The two examples show the process of solving inequality with variables on both sides are
3 + x > 3x - 6
3 - 4x < 2x + 8
The process is shown below.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
Let us consider an inequality:
3 + x > 3x - 6 ____(1)
3 - 4x < 2x + 8 _____(2)
We will solve for x.
From (1),
3 + x > 3x - 6
Subtract 3 on both sides.
3 + x - 3 > 3x - 6 - 3
x > 3x - 9
Add 9 on both sides.
x + 9 > 3x - 9 + 9
x + 9 > 3x
Subtract x on both sides.
x + 9 - x > 3x - x
9 > 2x
Divide 2 on both sides.
9/2 > x
x < 9/2
This means that x must be less than 9/2.
From (2),
3 - 4x < 2x + 8
Subtract 3 on both sides.
3 - 4x - 3 < 2x + 8 - 3
- 4x < 2x + 5
Subtract -2x on both sides.
-4x - 2x < 2x + 5 - 2x
-6x < 5
Divide both sides by 6.
-x < 5/6
Since we can not keep a negative sign with x we will multiply a negative on both sides and flip the inequality.
- (-x) > -5/6
x > -5/6
Thus,
The two examples show the process of solving inequality with variables on both sides are:
3 + x > 3x - 6
= x < 9/2
3 - 4x < 2x + 8
= x > -5/6

A 50-centimeter piece of wire is bent into a circle. What is the diameter of the circle? What is the radius of the circle? What is the area of the circle?
Answer:
The diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm
The radius will be 15.9134 ÷2 = 7.9567 cm or about 7.96 cm
The area of a circle is given by \pi × square of radius
Area = 3.142 × 7.96×7.96 = 199.0821 square cm
Answer:
the diameter would be half of the original length because it needs to be a circle so each half of the circle would equal 25 centimeters
