Let be the amount of water that evaporates. At the start, the solution in the tub consists of 2.5 gallons of salt (5% of 50 gallons). After
gallons of water evaporates, we're left with a solution with total volume
gallons, and 8% of this amount should be salt, or
gallons of salt. The amount of salt in the tank before and after evaporation remains unchanged, so
gallons of water need to be evaporated.
The isosceles triangle is proved below.
<h3>How to illustrate the triangle?</h3>The complete information wasn't found. The proofing of the triangle will be illustrated. It should be noted that the angles opposite to the equal sides of an isosceles triangle are also equal.
Proof: Consider an isosceles triangle ABC where AC = BC.
We need to prove that the angles opposite to the sides AC and BC are equal, that is, ∠CAB = ∠CBA.
We first draw a bisector of ∠ACB and name it as CD.
Now in ∆ACD and ∆BCD we have,
AC = BC (Given)
∠ACD = ∠BCD (By construction)
CD = CD (Common to both)
Thus, ∆ACD ≅∆BCD (By SAS congruence criterion)
So, ∠CAB = ∠CBA (By CPCT)

Answer:
Step-by-step explanation:
Let t represent the number of years since 2005.
We have been given that the number of people afflicted with the common cold C in the winter months steadily decreased by 202 each year from 2005 until 2010.
The number of people decreased in t years would be .
We are also told that in 2005, 12,073 people were afflicted. So 12,073 will be initial value.
We will represent our given information in an equation as , where,
m = Slope of line,
b = The initial value.
Since the number of people afflicted with the common cold C in the winter months steadily decreased, so slope will be negative.
Substitute the given values:
Therefore, our required equation would be .
