Answer:
A dilation of 2 about the origin.
Step-by-step explanation:
You can see in the original figure the points are half the points of the transformed figure.
For example the coordinates of H are (0.5,0)
The coordinates of H' are (1,0)
Since 0.5 * 2 = 1
There is a dilation of 2 about the origin.
Answer:
720 kph
Step-by-step explanation:
The ratio of times is ...
new time/original time = (1 2/3 h)/(5 h) = (5/3 h)/5 h) = 1/3
For the same distance, the ratio of speeds must be the inverse of this:
new speed/original speed = s/240 = 1/(1/3) = 3
s = 240(3) = 720 . . . . km/h
The aeroplane must travel at a speed of 720 km/h.
Answer:
D
Step-by-step explanation:
495 / 45 = 11 hours
Option D
Answer:
5
Step-by-step explanation:
5 because it can only go into itself one time, 5 x 2 is 10 and 5 x 6 is 30
