Answer:
m = 17
Explanation:
From the question we were given that
Triangle WZY is bisected by ZX; ZW = ZY
∠YXZ = (6m – 12)°
Based on the characteristics of the triangle, we see that triangle WYZ is an isosceles triangle (that is, triangle WXZ is equal to triangle YXZ)
<YXZ = <WXZ = 90°
Using ∠YXZ = (6m – 12)°
We have:
(6m – 12)° = 90°
6m = 90 + 12 ⇒ 6m = 102
m = 102 ÷ 6 = 17
m = <u>17</u>
<u>We therefore see that m is equal to 17</u>
The best assessment of Gina's prediction is that the several medium-sized cubes will dissolve faster than the large cube of sugar.
<h3>How does surface area affect solubility?</h3>
The surface area of a substance refers to the total area on the surface of that object.
Surface area plays a vital role in the dissolution of a substance. When a solute dissolves, the action takes place only at the surface of each particle.
This suggests that when the total surface area of the solute particles is increased, the solute dissolves more rapidly, hence, the best assessment of Gina's prediction is that the several medium-sized cubes will dissolve faster.

Answer:
See explanation
Explanation:
The boiling point of a substance at a location depends mostly on the atmospheric pressure in that location. The lower the atmospheric pressure in a location, the lower the boiling point and vice versa.
Boiling point is defined as the temperature at which the vapor pressure of the liquid becomes equal to the atmospheric pressure.
In Denver (the mile high city), alcohol will boil at a lower temperature(due to its high altitude) than in Houston because pressure decreases with height.
