Line art drawing of parallel lines and curves.
In geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. By extension, a line and a plane, or two planes, in three-dimensional Euclidean space that do not share a point are said to be parallel. However, two lines in three-dimensional space which do not meet must be in a common plane to be considered parallel; otherwise they are called skew lines. Parallel planes are planes in the same three-dimensional space that never meet.
Parallel lines are the subject of Euclid's parallel postulate.[1] Parallelism is primarily a property of affine geometries and Euclidean geometry is a special instance of this type of geometry. In some other geometries, such as hyperbolic geometry, lines can have analogous properties that are referred to as parallelism.

Answer:
total sales price = $21,000
Step-by-step explanation:
given data
depth = 80 feet
area = 4,800 square feet
sold = $350 per front foot
to find out
total sales price
solution
first we get here front feet that is the front length of a parcel
front feet = 
...................1
front feet = 
front feet = 60
so total sales price will be
total sales price = 60 × $350 per front foot
total sales price = $21,000
Answer:
The amount invested at 4% is $20,500 and the amount invested at 10% is $500
Step-by-step explanation:
Let
x -----> the amount invested at 4%
(21,000 -x) ----> the amount invested at 10%
we know that
The interest of the amount invested at 4% plus the interest of the amount invested at 10% must be equal to $870
so
Solve for x
therefore
The amount invested at 4% is $20,500 and the amount invested at 10% is $500
