Statement A: The line is on a different plane from the points. Statement B: The line lies on only one plane. Statement C: The line is on the same plane as the points. Statement D: The line passes through only one plane. Only statement is true. Reset Next
Statement C is correct
The line lies on the same plane as the points.
What is a 3d Plane?A 3-d or three-dimensional plane is called a hyperplane.
The three axes X-axis, Y-axis, and Z-axis are mutually perpendicular to each other.
We can represent a plane in vector form using the following equation. (p — p₀) . n = 0
Let the line is passing through two points on a given plane. Then, this is the line joining the two points and so all the points lying on this line must also lie on the plane. This clearly tells that the line completely lies on the same plane as the points.
the correct option is Statement C. The line is on the same plane as the points

What is this I need help quick
The county fair charges $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75 at the fair. Jermaine spent his money only on ride tickets and fair admission. The price of the fair admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Define your variables.
(b) Write a linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission.
Answer:
see explanation
Step-by-step explanation:
$1.25 is the cost per ticket
Jermaine bought 25 tickets in total
Spent a total of $43.75
y = total cost
x = number of ride tickets
1.25 ( 25 ) = 31.25
31.25 is the total money spent on ONLY tickets.
To find the cost of admission...
43.75 - 31.25 = 12.50
The cost of admission is $12.50
Equation: 1.25x + 12.5 = y
Find the measure of ∠ 1
a 180°
b 30°
c 60°

Answer:
120
Step-by-step explanation:
Using the theorems of geometry, you know that all angles of a triangle add up to 180º. We can use an equation after looking at both angles, and the total:
30 + 30 + x = 180
60 + x = 180
x = 180 - 60

How to find the lengths of similar triangles?We are given that ΔDEF ∼ △RST.
This means that ΔDEF is similar to △RST.
From the concept of similar triangles, all corresponding sides are usually in the same ratio. Thus, applying this to our given triangles, we have;
DE/RS = EF/ST = DF/RT
This means when we plug in the relevant values, we will get;
(x + 5)/12 = (x + 7)/(x + 12) = 6/(x + 6)
Thus, we can say that;
(x + 5)/12 = 6/(x + 6)
Cross multiply to get;
(x + 5)(x + 6) = 72
x² + 11x + 30 - 72 = 0
x² + 11x - 42 = 0

Solve for the legs of the 45-45-90 triangle.
Answer:
1st answer option
Step-by-step explanation:
the 45° side angles make this an isoceles triangle (both legs are equally long).
therefore, x = y.
Pythagoras gives us
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90° angle), and a and b being the legs.
so, we have
(5 × sqrt(2))² = x² + y² (remember, x = y)
(5 × sqrt(2))² = x² + x²
25 × 2 = 2x²
25 = x²
x = 5
because of x = y
y = 5
If Triangle ABC has been translated 4 units to the right into Triangle DEF, what are the coordinates of Point E?
Triangle ABC has been translated 4 units to the right into triangle DEF. Then, the coordinates of point E is (6, -2).
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Given that, triangle ABC has been translated 4 units to the right into Triangle DEF.
From the given coordinate plane A(-8, -2), B(2, -2) and (-4, -9)
When the shape is moved towards the right by k units, then replace x with x + k.
Now,
A(-8, -2) → D(-8+4, -2)=D(-4, -2)
B (2, -2) → E(2+4, -2)=E(6, -2)
C (-4, -9) → F(-4+4, -9)=F(0, -9)
Therefore, the coordinates of point E is (6, -2).

tina spends 65$ on supplies to start a dog washing business. she earns $21 every time she washes a dog. what is w, the number of dogs tina must wash to earn a profit of $40
By solving an equation, we know that the value of w or the number of dogs Tina must wash to earn a profit of $400 is 5.
What are equations?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
So, using the information given, the equation can be formed as:
21w - 65 = 40
Now, solve for the subject w to get the value of w as follows:
21w - 65 = 40
21w = 40 + 65
21w = 105
w = 105/21
w = 5
Therefore, by solving an equation, we know that the value of w or the number of dogs Tina must wash to earn a profit of $400 is 5.

toby buys a new mp3 player for the price of 45.5. what is the total amount his credit card is charged if the sales tax is 7%
A truck driver is driving from Nome, Alaska, to Death Valley, California. Because he is traveling between locations with extreme temperatures, he needs to check the weather continuously to make sure the gas in his truck remains in liquid form. The gas he uses freezes at −40° F and evaporates at 140° F.
Part A: Write an inequality to represent the temperatures at which the gas in the truck will remain in liquid form. (2 points)
Part B: Describe the graph of the inequality completely from Part A. Use terms such as open/closed circles and shading directions. Explain what the solutions to the inequality represent. (4 points)
Part C: In January 1989, the temperature in Nome, Alaska, dropped to −49° F. Would the gas in the driver's truck have remained in liquid form so he could have driven on this day? Why or why not? (4 points)
(A) The required inequality is, -40°F < x < 140°F.
(C) The gas has freezing point of -40°F, that means below that temperature the gas will freeze.
What is inequality?
In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol (≠)" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.
(A) Let the liquid range is from -40°F to 140°F.
Let x be the range.
So, the required inequality is,
-40°F < x < 140°F
(B) The graph of inequality is attached below.
(C) Since the gas has freezing point of -40°F, that means below that temperature the gas will freeze.
(-49°F < 40°F)
Hence, the gas will freeze.

a club has 6 men and 2 women. a committee of two people is selected randomly. Find the expected number of women on the committee
The required expected number of women on the committee is 1/2 or 0.5.
The expected number of women on the committee can be found by calculating the probability that a woman is selected for the committee and then multiplying that probability by the number of people on the committee.
There are a total of 6 + 2 = 8 people in the club, and the committee has 2 people.
Given the committee is selected randomly, the probability that a particular person is selected for the committee is 2/8 = 1/4.
There are 2 women in the club, so the probability that a woman is selected for the committee is 2/8 = 1/4.
The expected number of women on the committee is the probability that a woman is selected for the committee multiplied by the number of people on the committee, which is (1/4) * 2 = 1/2.
Thus, the expected number of women on the committee is 1/2 or 0.5.
