Answer:
Dilation
Step-by-step explanation:
A dilation is a type of transformation that changes the size of the image. The scale factor measures how much larger or smaller the image is.
In this example, ΔABC is dilated as seen in the picture because it the picture itself got bigger.
The image, ΔADE is now a dilated version of the pre-image ΔABC

Answer:
Step-by-step explanation:
We have a circle that is split in three sections, two of which we know and we are asked to find the third missing section.
For the circle, we know that 4/5 and 1/10 is fit. Now we need the last one, to solve, we need to get the same denominator and see how much is missing.
Since 1/10 is our highest denominator, let's change 4/5 to have 10 as a denominator. Which would be through multiplying 5 to get 10.
What times 5 equals 10?
2
Now multiply both numerator and denominator by 2 to get our portion.
Now we have the same denominator, let's add our two fractions and see how much we have left.
8/10 + 1/10
9/10
We have 1/10 missing, therefore 1/10 is the answer.
