Answer:
Step-by-step explanation:
Let the point P is at the origin (0, 0).
Then the coordinates of A, B and C will be (8, 4), (-2, 2) and (4, -4) respectively.
Rule for the dilation of a point by a scale factor = k
(x, y) → (kx, ky)
If k = 
Then, A(8, 4) → A'(4, 2)
B(-2, 2) → B'(-1, 1)
C(4, -4) → C'(2, -2)
Now we can plot the new image with points A', B' and C'
Answer:
4 : 1
Step-by-step explanation:
(3 days : 18 hours) this is a ratio , where both the units must be same before simplifying.
1 day = 24 hours, 3 days = (3 × 24) hours
3 days = 72 hours
Now both the units are same, so we can easily simplify now.
72 hours : 18 hours
36 : 9 = 12 : 3
= 4 : 1 ( Answer)
Answer:
1:5
Step-by-step explanation:
For this problem, you just have to evaluate the proportion of the length of the sides between triangles nmo and kml.
So LM = 12, which corresponds to OM = 60 (12 X 5 = 60)
KM = 10, which corresponds to NM = 50 (10 X 5 = 50)
To find the probability of the statistic class that it could be done at the period at 50.5 and 51.25 minutes and not their usual duration of 49 and 49 minutes so to get the probability you must subtract the time and would come up with 0.75 minutes and then divide it by 10 so the probability is 0.075
