Define perpendicular lines.
A.
Lines that cut across two or more lines.
B.
Two coplanar lines that intersect at a 90 degree angle.
C.
Two coplanar lines that do not intersect.
D.
Two non–coplanar lines that do not intersect
Perpendicular lines are two coplanar lines that intersect at a 90-degree angle, option B in the question.
Perpendicular lines are defined as two coplanar lines that intersect at a 90 degree angle. This means that the correct answer to the given question is B. It's important to understand that when lines are perpendicular, they create four right angles at the point where they intersect. Various geometrical theorems relate to the properties of perpendicular lines, for example:
Theorem 15 states that if two planes are perpendicular, a line drawn in one perpendicular to their intersection is perpendicular to the other plane.
Theorem 14 explains that if a line is perpendicular to two intersecting lines at their intersection, it is perpendicular to all lines on their plane that pass through this point.
Theorem 11 describes that if two equal lines in a plane are erected perpendicular to a given line, the line joining their extremities will make equal angles with them.
In advanced contexts, such as the geometry of spacetime, perpendicularity can be defined differently, often using the concept of the dot product being zero to identify perpendicular vectors.
the area of a circle is 196 pi square inches. what is the exact length of the circle's radius?
Area of a circle:
[tex]A=\pi r^2[/tex] "r" is the radius
Since you know [tex]A=196\pi[/tex] in², you can plug (196[tex]\pi[/tex]) for "A" in the equation
[tex]A=\pi r^2[/tex]
[tex]196\pi=\pi r^2[/tex] Divide pi on both sides
196 = r² Square root both sides
14 = r
The exact length of the circle's radius is 14 inches.
The formula to calculate the area (A) of a circle is given by:
[tex]A = π * r^2[/tex]
where "r" is the radius of the circle.
In this case, we are given that the area of the circle is 196π square inches. So we can set up the equation:
196π = π * [tex]r^2[/tex]
To find the radius (r), divide both sides of the equation by π:
[tex]r^2[/tex] = 196
Now, solve for the radius:
r = √196
r = 14
Therefore, the exact length of the circle's radius is 14 inches.

On a number line, what is the distance between -57 and 13?
Answer: 70 units
One way to find this answer is to get a very large number line (perhaps from -100 to 100; counting by 1s) and count out the number of spaces from -57 to 13. This method is impractical because it would take a long time.
A shorter method is to subtract the values and make the result positive. So we could say -57 - 13 = -70 which has an absolute value of 70. Or we can say 13 - (-57) = 13 + 57 = 70. Either way, the distance between the values on the number line is 70 units.

Answer: 39.25 miles per gallon.
Step-by-step explanation: To find miles per gallon, divide 314 miles by 8 gallons =
39.25 miles per gallon.
The answer is 39.25
note: if your teacher wants a fraction instead of a decimal, then it would be 157/4
=============================
Explanation:
Divide 314 over 8 to get 314/8 = 157/4 = 39.25
----
You can think of it as the ratio
314 miles: 8 gallons
(314/8) miles: (8/8) gallons <--- divide both parts by 8
(157/4) miles: 1 gallon
39.25 miles: 1 gallon
Meaning you can drive 39.25 miles on one gallon of gas

3(x−0.50)=5.97
what does x equal?
Answer:
x=2.49
Step-by-step explanation:
3(x−0.50)=5.97
Distribute the 3
3x - 3*.5 = 5.97
3x -1.5 = 5.97
Add 1.5 to each side
3x -1.5+1.5 = 5.97+1.5
3x = 7.47
Divide each side by 3
3x/3 = 7.47/3
x=2.49

Cain is about to start a new job and his opponent employer has offered him two different options to get paid. Option A gives Cain $20 to start plus an additional $10 an hour option b gives Kane $40 to start plus an additional $5 an hour. Define your variables then create a system of equations.
Define Variables:
x =______
y =______
Equations
Option A: ______
Option B: ______
Hello,
So Y variable is what you would start with.
20 <= he'll start off with for a
40 <= what he'll start off with for b
And X variables would be the # of hours you're working.
10 <= meaning every hour worked is worth 10 dollars
5 <= meaning every hour worked will be paid 5 dollars
So let's just say for option a he works two hours
(Option A)
10 (2) + 20
20 + 20
= 40
(Option B)
5 (2) + 40
10 + 40
50
As for your equations

if the discount is 30% and the sale price is $206.50 what is the original price
To determine the original price before a 30% discount resulted in a sale price of $206.50, we calculate the sale price as 70% of the original price, leading to the original price being $295.00.
Explanation:If the discount is 30% and the sale price is $206.50, we need to determine the original price before the discount. To do this, we first understand that the sale price represents 70% of the original price, because a 30% discount has been applied. Thus, to find the original price, we can set up the following equation where original price × 70% = $206.50.
Converting 70% to decimal form, we get 0.70. The equation then becomes original price × 0.70 = $206.50. To find the original price, we divide both sides of the equation by 0.70:
Original price = $206.50 / 0.70
Original price = $295.00
Therefore, the original price of the item before the 30% discount was applied is $295.00.

You want to determine your speed running across the room. What is one piece of data you need?
A) The distance you run
B) When you start your stopwatch
C) How big each step is
D) How fast you are moving
I know its not C)
Answer:
D) How fast you are moving
While all the others are useful information (except C), you are trying to solve for your speed, or mph. How fast you are moving is also solved using mph (or something like it).
speed = mph = how fast you are moving ∴ speed = how fast you are moving
~
Answer:
Choice A
Step-by-step explanation:
You need the distance and the time, which are D and T respectively. The speed or rate is R = D/T. You divide the distance over the time. Example: if run 10 miles in 2 hours, then your speed is R = D/T = 10/2 = 5 mph.
Choice A is correct because we need the distance.
Choice B is close to knowing the time T, but we would need to know the duration and not when the stopwatch was clicked on. In other words, we need to know the difference in when it was started and stopped. Simply knowing the starting point isn't enough. We can cross this off the list.
Choice C is close to what choice A is saying, but choice A is more accurate. We can cross this off the list.
Choice D is what we want to know. If we know how fast we're moving, then there's no need to calculate the speed. So we can cross choice D off the list as well.

Karen is using an indirect method to prove that segment DE is not parallel to segment BC in the triangle ABC shown below:
She starts with the assumption that segment DE is parallel to segment BC. Which inequality will she use to contradict the assumption?
A. 6:7 ≠ 2:7
B. 6:8 ≠ 7:10
C. 6:2 ≠ 7:10
D. 6:2 ≠ 3:2
Answer:
Option B
Step-by-step explanation:
In order to prove that segment DE is not parallel to segment BC, Karen takes an indirect way, that is she assumes that DE is parallel to BC, then by using the basic proportionality theorem,
[tex]\frac{AD}{AB}=\frac{AE}{AC}[/tex]
Now, AD=6, AB=AD+DB=8, AE=7 and AC=10
therefore, [tex]\frac{6}{8}=\frac{7}{10}[/tex] according to basic proportionality theorem, but in actual, [tex]\frac{6}{8}{\neq}\frac{7}{10}[/tex].
Thus, DE is not parallel to BC, therefore Option B is correct.
Answer:
B, 6:8 ≠ 7:10.

It takes 24 feet of fence to surround a square piece of land in Sam's backyard. Sam wants to plant flowers everywhere but on the diagonal sidewalk (shaded in the diagram attached). Note that there is 1 foot of sidewalk along two sides of the square as indicated in the diagram attached. What is the area of the sidewalk?
Answer:
Option B. 5.5 ft²
Step-by-step explanation:
Perimeter of the square piece of land = length of fence required
4(length of a side of the square) = 24 ft
Length of a side = 6 ft
Area of the square land = (Side)²
= 6²
= 36 square ft
Area of the side walk = Area of the square - [Area of two triangles separated by the sidewalk]
= 36 - [[tex]\frac{1}{2}(\text{Area of the square})+\frac{1}{2}(\text{Base})\tmes (\text{height})[/tex]]
= 36 - [[tex]\frac{36}{2}+\frac{1}{2}(6-1)(6-1)[/tex]]
= 36 - (18 + 12.5)
= 36 - 30.5
= 5.5 ft²
Therefore, Option B. is the correct answer.
