Percent Mixture
The large square
contains 100 smaller
squares. The large
square represents 1 liter
of a solution.
1 liter
Percent Mixture
 Each
small square
represents 1%. To
show, for instance, a
10% solution, shade
any 10 of the smaller
squares.
Percent Mixture
 Begin
with 10 liters of a 10% acid solution.
Percent Mixture
 Add
5 liters of a 4% acid solution.
Percent Mixture
 There
are 15 liters. This
is represented by the
1500 small squares.
There are 120 shaded
small squares. The
percent concentration of
the new solution is

Concept of Variable

A variable is a symbol that represents a
quantity capable of assuming any of a set
of values.
𝜋, e, i
 ax2 + bx + c = 0
a2 + 3a – 10 = 0
 y = mx + b
