Answer:
-2 and -12
Explanation:
A dilation is a transformation of a geometric image that is known to change its size not it shape.
The size of the figure basically depends on the scale factor (k).
When k >1 then there would be expansion.
When k <1 then there would be contraction.
When k=1 then no change in size
I.e for conraction the scale factor (k) must be negative
from the given options, the scale factor produce a contraction under a dilation of the original image would be -2 and -12
<h3 /><h3>Hence the correct answers are:-2 and -12 </h3>

Hmmm it would be 2 I think but I am not sure
Answer:
volume of the mixture is (0.575+0.300)-----> 0.875 m³
Explanation:
we know that
density=mass/volume--------> volume=mass/density
step 1
find the volume of water
mass=575 kg
density of water=1000 kg/m³
volume of water=mass/density-----> 575/1000----> 0.575 m³
step 2
find the volume of ice
mass=275 kg
density of ice=916 kg/m³
volume of ice=mass/density-----> 275/916----> 0.300... m³
the volume of water is 0.575³
the volume of ice is 0.300.. m³
volume of the mixture is (0.575+0.300)-----> 0.875 m³
