Answer and Step-by-step explanation: Rotation is a "movement" of a geometric figure in order to transform one in another. In rotation, the shape and size of the figure is the same, so they are congruent.
A geometric figure can be rotated clockwise or counterclockwise and by different angles.
One way to recognized the angle of rotation is comparing the points of the figure and its rotated image.
On the figure below, triangle DOG has coordinates:
D (-2,1)
O (-3,3)
G (1,1)
And its image:
D' (2,-1)
O' (3,-3)
G' (-1,-1)
Comparing both set of coordinates, we observe:
D (-2,1) → D' (2,-1)
O (-3,3) → O' (3,-3)
G (1,1) → G' (-1,-1)
that the coordinates for ΔDOG and ΔD'O'G' are opposite to each other, i.e.:
(x, y) → (-x,-y)
rotating counterclockwise.
Since coordinates are opposite and rotation is counterclockwise, ΔD'O'G' is rotated by 180° related to ΔDOG.

Johan is mixing paint he mixes 2 2/3 pints of blue paint and 4 1/6 pints of yellow paint. Which of the following has a ratio of blue paint to yellow paint that is proportional to amounts used in johans paint mixture
Answer:
R = 16:25
Step-by-step explanation:
Given that,
Johan mixes 2 2/3 pints of blue paint and 4 1/6 pints of yellow paint.
We need to find the ratio of blue paint to yellow paint. It can be calculated as follows :
[tex]R=\dfrac{\text{blue paint}}{\text{yellow paint}}\\\\=\dfrac{2\dfrac{2}{3}}{4\dfrac{1}{6}}\\\\=\dfrac{\dfrac{8}{3}}{\dfrac{25}{6}}\\\\=\dfrac{8}{3}\times \dfrac{6}{25}\\\\=\dfrac{16}{25}[/tex]
So, the required ratio is 16:25.

Instructions: Given the following image of two parallel lines cut by a transversal, find the value of x.
Answer:
Step-by-step explanation:
these lines are congruent, so they equal the same thing
9x + 1 = 10x - 5
subrtact 9x from 10x and add 5 to 1
6 = 1x
which is 6 = x
so x would be 6
since your thing doesnt want spaces the setups for them would be:
congruent
9x+1=10x-5
6

A house on the market was valued at 238,000. After several years, the value decreased by 15% . By how much did the house's value decrease in dollars? What is the current value of the house? Decrease in value and current house value
Answer:
The current house value is $202,300 and the house's decrease in dollars is $35,700.
Step-by-step explanation:
The house on the market was valued at $238,000. After years, it decreased by 15%. So, let's calculate 15% of the total amount.
238,000 x 0.15 = $35,700
Therefore, the house's decrease in dollars is $35,700
To calculate the current value of the house, we need to subtract the value decrease from the original amount.
238,000 - 35,700 = $202,300
Therefore, the current house value is $202,300.
Hope this helps! :)

What is the difference between 234 and 250
Hey there!
If you ever come across the word “difference” in mathematics (or math) it usual means “SUBTRACT” (or SUBTRACTION) so basically you’re going to SUBTRACT 234 from 250
Equation:
234 - 250 = -16
