Conguence is mantained, because reflection preserve distances and angles.
Orientiation is not preserved. You can check this yourself: try to look at a watch through a mirror. You will see it going counterclockwise.
Answer:
It will take 12 hours
Step-by-step explanation:
Distance equals rate times time
d = rt
We know the distance and the rate
240 = 12 * t
Divide each side by 12
240/12 = 12t/12
20 = t
It will take 12 hours
Answer: 28
Step-by-step explanation: In this problem, we're given information about the parts of a segment and we're asked to find the value of x.
To find the value of x, we can use the <em>segment addition postulate</em>.
Looking at the diagram, it should make since that RS + ST = RT.
So 4x + 3x + 11 = 60 or 7x + 11 = 60.
Subtracting 11 from both sides and solving for x, we get x = 7.
Since RS is 4x, we can substitute a 7 in for x to get 4(7) or 28.
Answer:
An equation that represents the given situation is 
and the additional number of students that can be seated is 47
Step-by-step explanation:
Number of students already seated in school cafeteria = 203
Let x be the additional number of students that can be seated
So, Total number of seats available in school cafeteria = 203+x
We are given that the school cafeteria seats 250 students
So, 203+x=250
Hence an equation that represents the given situation is and the additional number of students that can be seated is 47
