Answer:
p = q
Step-by-step explanation:
There are 180 degrees in a triangle. If you subtract 50 and 60 from 180, you get 70. If you subtract 30 an 80 from 180, you get 70. therefore p = q.

Triangle ABC has coordinates A(1,-1), B(0,2), and C(2,1) and it is reflected over the line y = x to form triangle A'B'C'. What are the coordinates of triangle A'B'C answer the question using complete sentences...please help
Answers
Answer:
The coordinates of triangle A'B'C' are A' (-1 , 1) , B' (2 , 0) , C' (1 , 2)
Step-by-step explanation:
* Lets revise some transformation
- If point (x , y) reflected across the x-axis
∴ Its image is (x , -y)
- If point (x , y) reflected across the y-axis
∴ Its image is (-x , y)
- If point (x , y) reflected across the line y = x
∴ Its image is (y , x)
- If point (x , y) reflected across the line y = -x
∴ Its image is (-y , -x)
* Lets solve the problem
- ABC is a triangle, where A = (1 , -1) , B = (0 , 2) , C = (2 , 1)
- The Δ ABC reflected over the line y = x to form ΔA'B'C'
∵ The image of the point (x , y) after reflected across the line y = x
is (y , x)
∴ We will switch the coordinates of each point in Δ ABC to find the
coordinates of Δ A'B'C'
# Vertex A
∵ A = (1 , -1) ⇒ x = 1 , y = -1
∴ The x-coordinate of the image is -1
∴ The y-coordinate of the image is 1
∴ A' = (-1 , 1)
# Vertex B
∵ B = (0 , 2) ⇒ x = 0 , y = 2
∴ The x-coordinate of the image is 2
∴ The y-coordinate of the image is 0
∴ B' = (2 , 0)
# vertex C
∵ C = (2 , 1) ⇒ x = 2 , y = 1
∴ The x-coordinate of the image is 1
∴ The y-coordinate of the image is 2
∴ C' = (1 , 2)
* The coordinates of triangle A'B'C' are A' (-1 , 1) , B' (2 , 0) , C' (1 , 2)
AB is tangent to \odot ⊙ O at A (not drawn to scale). Find the length of the radius r, to the nearest tenth.
Answers
Answer:
r = 15.2
Step-by-step explanation:
Where AB meets the circle creates a right angle. This is a right triangle problem involving missing sides. This means that we will use Pythagorean's theorem to find the length of the radius. Pythagorean's theorem applies this way:
[tex]10^2+r^2=(r+3)^2[/tex]
Foiling the right side gives us the equation:
[tex]100 + r^2=r^2+6r+9[/tex]
When we combine like terms, we find the squared terms cancel each other out, leaving us with
100 = 6r + 9 and
91 = 6r so
r = 15.2

Which of the following quadrilaterals have diagonals that are perpendicular to each other? Check all that apply.
Answers
Answer: Option B and option D.
Step-by-step explanation:
We know that a quadrilateral is a 2-dimensional closed shape that has four sides.
By definition the diagonals of a quadrilateral are the lines that connect two non-adjacent vertices.
The following quadrilaterals have diagonals that are perpendicular to each other (also known as perpendicular bisector diagonals), which means that they form four angles of 90 degrees (right angles): Rhombus and Square.
Therefore the answers are: the option B and the option D.
The quadrilaterals that have diagonals perpendicular to each other are:
a. Rectangle
b. Rhombus
d. Square
In a rectangle, the diagonals are always perpendicular to each other. The same applies to a rhombus, which is a special case of a parallelogram with all sides equal.
Similarly, a square is a special type of rectangle and rhombus, so its diagonals are also perpendicular. However, in a general parallelogram, the diagonals are not necessarily perpendicular. Therefore, the correct options are a, b, and d.
Therefore, The quadrilaterals that have diagonals perpendicular to each other are:
a. Rectangle
b. Rhombus
d. Square

Aubrey was offered a job that paid a salary of $45,000 in its first year. The salary was set to increase by 2% per year every year. If Aubrey worked at the job for 20 years, what was the total amount of money earned over the 20 years, to the nearest whole number?
Answers
Aubrey's total earnings over 20 years, given a starting salary of $45,000 and a 2% annual increase, would be approximately $1,157,357, calculated using the formula for an increasing annuity.
Explanation:The subject of this question is compound interest, which is a mathematical concept used to calculate the future value of an investment or loan. In this case, Aubrey's salary is subject to an annual increase of 2%, which is compounded yearly.
To calculate the total amount earned over 20 years, we need to use the formula for the future value of a salary subject to yearly increases: Future Value = Salary * ((1 + Rate)^Years). Substitute the given values into the equation: Future Value = $45,000 * ((1 + 0.02)^20). Calculating this gives a value of approximately $66,207.11, which would be Aubrey's salary in the 20th year.
To find the total earnings over 20 years, you would add each year's salary together. However, it is much more complex due to the increasing salary. In this case, an annuity formula can be used.
The formula is: Total Earnings = Pmt * ((1 - (1 + r) ^ -n) / r). 'Pmt' is the first period payment, 'r' is the interest rate, and 'n' is the number of payments. Here, Pmt = $45,000, r = 2% or 0.02, and n = 20 years. After substituting everything in, the result should be around $1,157,357 rounded to the nearest whole number.

Q1: How do you identify the solution to a system of two linear equations in two variables from their graphs?
Q2: What causes a system of two equations in two variables to have no solution? What causes a system of two equations in two variables to have infinitely many solutions?
Q3: How do you determine whether to use substitution or elimination to solve a system of equations?
Answers
Q1: The solution of a system of two linear equations in two variables is the point where their graphs intersect. At that point, the (x, y) pair satisfies both equations.
__
Q2: There will be no solution when the lines representing the equations do not intersect. That will only happen when they are parallel. (We say the equations are "inconsistent.")
There will be infinitely many solutions when the lines overlap. That is, the equations for them are essentially the same equation. (We say the equations are "dependent.")
__
Q3: Elimination is easiest when the coefficients of one of the variables are opposites of each other, or if one is a factor of the other. Substitution is easiest if one of the equations is easily put in the form x = ( ) or y = ( ).
If neither or both conditions hold, the choice is by student preference. (In this latter case, solution using Cramer's rule may be simplest.)

Answers
Answer:
No; the angle of elevation of the front bottom of the dump truck body will be only 31°, much smaller an angle than the required 50°
Step-by-step explanation:
Let the body of the truck rest upon the x-axis with the rear body at (0, 0). The front of that body is located at (15, 0). The dump body is elevated to 9 ft.
We thus have a right triangle with base 15 ft and height 9 ft, and want to know what the angle is. The angle is at (0, 0). The front of the body is at (0, 15), and when elevated that point will be located at (15, 9).
The tangent function relates the angle to the opposite side (length 9 ft) and the adjacent side (length 15 ft):
tan Ф = opp / hyp = 9 / 15 = 31 degrees.
NO: the elevation of the front of the dump truck body is only 31° approx. The clay will not easily dump from the body.

Answers
Answer:
10 liters of orange juice5 liters of champagneStep-by-step explanation:
Let c represent the number of liters of champagne Lauren uses. Then (15-c) will be the number of liters of orange juice. The total cost of the mix will be ...
12c +1.50(15-c) = 5.00(15)
10.5c = 52.50 . . . . . subtract 22.50, simplify
52.50/10.5 = c = 5 . . . . divide by the coefficient of c
Then the amount of orange juice is ...
15 -c = 15 -5 = 10 . . . . liters
Lauren should use 5 liters of champagne and 10 liters of orange juice.
