Answer:
Lines AB and A'B' are similar, line A'B' being three times the size of line AB. They would not be congruent since a dilation isn't a rigid transformation but they would be similar. Their lengths would also be expressed in the form of a ratio which would be 1:3 if you do AB to A'B' and 3:1 if you do A'B' to AB. Hope this helped! :)
Step-by-step explanation:
The relationship between two lines AB and A’B’ is A'B'=3AB.
It is given that in the given figure larger figure was dilated using a scale factor of 3. It means the smaller and larger figures are similar and there corresponding sides are in the ratio 1:3.
The line AB connecting the two points of the smaller figure and line A'B' connecting the two points of the larger figure.
Since A'B' is corresponding line segment of AB in larger figure, therefore the ratio of AB to A'B' is 1:3.
By cross multiplication we get
The length of segment A'B' is 3 times of AB.

Answer:
B) 450
Step-by-step explanation:
You use the greater amount minus the lesser amount, times 30 minutes.
55-40=15
15 x 30=150

Answer:
You started with 32 muffins
Step-by-step explanation:
Let x represent how many muffins you started with.
Then three-fourth of this muffins equal 24.
This gives us the equation:
Multiply both sides by 4/3 to obtain:
This simplifies to give:
