A rigid transformation is one that preserves all of the distances between points/vertices on an image. Dilation/scaling alters those distances, so A and C can’t qualify for that, and B implies a change in shape entirely, so that wouldn’t be a rigid transformation either. Only D) spinning a spinner would keep the shape the same, without altering any distances.
Answer:
Step-by-step explanation:
It's easier to figure it out when both fractions have the same denominator, so let's fix that:
17/40*15/15 is 255/600
8/15*40/40 is 320/600
Notice we are multiplying by a factor of 1 to get equivalent fractions
So 8/15 is bigger

12+6=18 18+18=36 total coins.
12 quarters:36 coins.
To simplify divide each side by 12.
12/12=1 36/12=3
The simplified ratio is 1:3.
Therefore the answer is B.

Answer: No triangle
Step-by-step explanation:
The given dimensions of triangle : 4.8 cm, 2.1 cm, and 2.6 cm
- The famous triangle inequality says that in any triangle the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side.
But
It means the sum of two sides (2.1 and 2.6) is less than the third side (4.8).
Therefore by triangle inequality, no triangle can be possible by the given measurement.
