An 80 metre long train crosses a 120 metre long platform in 20 seconds, what is the speed of the train per hour?
ans:
Total distance= length of train + length of platform
I.e 80+120= 200 m but need in kmph so 0.2 km
Time = 20 second but need in hours so 20/(3600)= 1/(180)
Speed = distance / time = 0.2*180= 36 kmph

Given that <2=<6.
Which theorem proves that line d is parallel to line e.
A. Alternate interior angle theorem
B.Converse of the alternate exterior angle
theorem
C.Converse of the alternate interior angle
theorem
D.Alternate Exterior angle theorem
Answer: B . Converse of the alternate exterior angle theorem.
The converse of the alternate exterior angle proves that line d is parallel to line e which is the correct answer would be an option (C).
What are Alternate Interior Angles?Alternate Interior Angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles.
According to the alternate exterior angles theorem, if two parallel lines are intersected by a transversal, the alternate exterior angles are congruent. In light of this, the converse of the alternate exterior angle theorem would state that if the two outside angles are congruent, the lines that the transversal cuts must be parallel.
The graph indicates that the outer angles are congruent (both equal x) shows that the lines are parallel.
Therefore, the converse of the alternate exterior angle proves that line d is parallel to line e.

2.) The original price of Airpods is $160.00. They
are on sale for 15% off. What is the discount

8.51348434552 to 3 decimal places
Answer:
8.513
Step-by-step explanation:
The round off to the number at three decimal places will be 8.513.
What is rounding off the numbers?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.
A number can be rounded off to its lower value if the number after the decimal is between 0 and 4. The number will be rounded off to its higher value if the number after it is between 5 and 9.
The round-off to the number 8.51348434552 to the three decimal places will be 8.513.

What was Bear B's average speed in
m/min? No units required for answer.
Given:
Graph of positions of Bear A and Bear B.
To find:
The average speed of Bear B in m/min.
Solution:
From the graph it is clear that initial point of graph of Bear B is (0,100) and the end point is (60,2800).
The average speed of Bear B is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{2800-100}{60-0}[/tex]
[tex]m=\dfrac{2700}{60}[/tex]
[tex]m=45[/tex]
Therefore, the average speed of Bear B is 45 m/min.

Graph the equation 2x−y=9 by plotting points.
Answer:
y=2x-9
Step-by-step explanation:
2x-y=9
-2x -2x
-y=-2x+9
-y/-y= -2x/-y+9/-y
y=2x-9
The required graph of equation 2x - y = 9 by plotting points is attached below.
To graph the equation 2x - y = 9 by plotting points, we can choose different values of x, solve for y, and then plot the corresponding points.
Here is a table of values:
x | y
0 | -9
1 | -7
2 | -5
3 | -3
4 | -1
5 | 1
Using these values, we can plot the points (0, -9), (1, -7), (2, -5), (3, -3), (4, -1), and (5, 1) on a graph.
The x-axis represents the values of x, and the y-axis represents the values of y. Connect the plotted points with a straight line to represent the equation 2x - y = 9.
Thus, the required graph of equation 2x - y = 9 is attached below.

Probability is a measure of how likely an event is to occur. Match one of the probabilities that follow with each statement of likelihood given.

This event will occur slightly less often than not.A. 0B. 0.1C. 0.3D. 0.45E. 1
Answer:
Kindly check explanation
Step-by-step explanation:
Verbal statement and associated probability:
P = 0 ; This event is Impossible event, it will never occur. It is the least value of probability an event can take.
P = 1 ; This event is certain, it will occur on every trial. It is the highest value of probability an event can have.
P = 0.6 ; very likely event, but will occur once in a while in a long sequence of trials ; very likely signifies a probability above average (0.5) though will not always occur.
P = 0.45 ; This event will occur slightly less often than not; as the probability value slightly falls below the average standardized probability value (0.5)
