Answer:
To find the scale factor for a dilation, we find the center point of dilation and measure the distance from this center point to a point on the preimage and also the distance from the center point to a point on the image. The ratio of these distances gives us the scale factor
Answer:
r = 4/3
Step-by-step explanation:
-20 = -15r
Divide both sides by -15.
-20 / -15 = r
The negatives cancel, so
20 / 15 = r
Simplify by taking 5 out of the numerator and denominator. 20/5 = 4, 15/5 = 3.
4 / 3 = r
<u>So r = 4/3.</u>
108
4 times 3 =12
12 times 3 =36
36 times 3 =108
etc
statements 1, 3, 4 are correct
The awnser is 1000 because 60 miutes in an hour, 50 mouse traps every half hour so 100 mouse traps an hour multiply that by 10 and you get 1000, i think.
