Answer:
Food color mixes faster in warm water than in cold water.
Molecules in a liquid have enough energy to move around and pass each other. This is why water can flow and take the shape of the container you pour it into.
Warm water has more heat energy than cold water, which makes the molecules in warm water move faster than molecules in cold water. The food coloring you add to the water is pushed around by the water molecules. Since the molecules in warm water move around faster, the food coloring spreads out quicker in the warm water than in the cold water.
Step-by-step explanation:
Hi there!
From the question;
The slope of the line is 5/10 or 0.5.
Also the equation of the line passes through the point (0,5).
Note: Use one point formula. {i.e (y-y1)=m(x-x1)}
So, use the formula here and keep the values;
(y-5) = 5/10(x-0)
or, 10(y-5) = 5x
or, 10y-50 = 5x
or, 5x - 10y +50 = 0
Therefore, the required equation is 5x - 10y +50 = 0 or x-2y+10 = 0.
Hope it helps!
Answer: 
==========================================================
Work Shown:
Focus entirely on triangle ABD (or on triangle BCD; both are identical)
The two legs of this triangle are AB = 8 and AD = 8. The hypotenuse is unknown, so we'll say BD = x.
Apply the pythagorean theorem.
So that's why the diagonal BD is exactly 
units long
