Answer:
Step-by-step explanation:
The range is the difference between the maximum and minimum values:
The mode is the most repeated value of the data set
- This is 3 (repeated 5 times)
Let <em>x</em> be the amount of salt in the solution.
At day's end, the concentration of salt in the beaker is
<em>x</em> / (4 L) = 0.08 = 8%
Solve for <em>x</em> to get
<em>x</em> = 0.08 (4 L) = 0.32 L
So at the beginning, the concentration of salt in the beaker was
(0.32 L) / (5 L) = 0.064 = 6.4%
Answer:
The measure of angle ABC = The measure of angle A prime B prime C prime
Step-by-step explanation:
we know that
The transformation of the figure is a reflection, so after the transformation the shape still has the same size, area, angles and line lengths.
the triangles ABC and A'B'C' are congruent
therefore
the corresponding sides and corresponding angles are equal
so
The relationship between the measures of the angles of the two triangles is
