Answer:
Applying brine on roadways accelerates the melting process because salt needs to be moist to be effective.
The cost per ton is higher for solid ice melting products than it is for brine
The salt in brine sticks to the roadway after the water part evaporates preventing the salt from being blown off by vehicles driving on the road.
Snow storms sometimes start as rain which may wash away the solid ice melting products
Explanation:
Brine is a concentrated salt solution used to remove ice from roads during winter. It functions by lowering the melting point of ice. Since brine is a solution, it works faster and accelerates the melting process because brine needs to be moist to be effective.
Similarly, it does not easily wash off roads as solid melting products does. It tends to stick better on roads even after the water evaporates.
Answer:
The correct answer is "efficiency"
Explanation:
The term efficiency refers to maximize and achieve the goals with the existing resources or less . It includes reducing the use of resources through maximizing return.

An efficiency manager, "do the things right with fewer resources (workforce, budget, time)"
Answer:
The decision to give up visiting popular Ouro Preto. (i think! :))
Explanation:
Opportunity cost is the profit lost when one choice is chosen over different. The idea is valuable only as a suggestion to consider all logical choices before making a judgment. If economists regard to the “opportunity cost” of a support, they indicate the importance of the next-highest-valued alternative use of that support.
The 500- pound weight be shifted 1 inch to the left to balance the plank on the fulcrum
This is further explained below.
<h3>What is
a fulcrum?</h3>
Generally, The point at which the beam is allowed to pivot is referred to as the fulcrum. When force is applied to one end of the lever, it causes the other end of the lever to become loaded with more weight. Because of this, a mass will be moved higher.
A beam or rigid rod that is pivoted at a fixed hi/nge, also known as a fulcrum, constitutes a lever, which is a basic machine. A body that is inflexible yet has the ability to rotate on a point on itself is called a lever. The lever may be broken down into three distinct categories according to the positions of the fulcrum, the weight, and the effort.
In conclusion, In order to keep the plank stable on the fulcrum, the weight of the 500-pound bar must be moved to the left by one inch.
