How is groundwater formed

When water percolates down through the soil

Why farmers use fertilizers containing nitrogen

Nitrogen is an essential plant nutrient, especially for growth.
Some plants require more nitrogen than others.

How many lines of symmetry does a regular polygon with 22 sides have

What tools did the Greeks use in geometric constructions

A straightedge and compass.

What kinds of polygons are symmetrical

All regular polygons

A polygon is symmetrical if its sides that cross the line of
symmetry are halved by the line of symmetry and if the sides that
do not cross the line of symmetry have the same positions in space,
the same lengths, and the same angles with their neighboring sides
as do the sides on the other side of the line of symmetry. The only
symmetrical triangles are isosceles triangles (equilateral
triangles are isosceles). The only symmetrical quadrilaterals are
squares, rectangles, rhombi (the line of symmetry connects either
pair of opposite corners), isosceles trapezoids, and kites.

What type of instrument is the guiro

Who is famous for popularizing reggae outside of Jamaica

Reflectional symmetry is the quality a design has if it maintains all characteristics when it is rotated about a point of symmetry

To trisect an angle you first construct an equilateral triangle

Rotational symmetry is the quality a design has if it maintains all characteristics when it is rotated about an axis lying in its plane

Lovers rock is a style of music created by slowing down what type of music

Is it true that you cannot bisect an angle using paper folding constructions

No. It is possible to fold an angle on paper to bisect it.

How many lines of symmetry does a regular polygon with 16 sides have

16. 8 through pairs of opposite vertices and another 8 through
the midpoints of opposite sides.

Which single container uses up the most resources from the environment

A steel bottle uses up the most resources from the
environment.

What are reasons used in the proof that the equilateral triangle construction actually constructs an equilateral triangle triangle

The following is the answer.

What are construction tools used for

Construction tools are used primarily in building
construction.

What symmetry is the quality a design has if it maintains all characteristics when it is rotated about an axis lying in its plane

How many lines of symmetry would a 10-sided regular polygon have

10 lines. Regular polygon of "x" sides has "x" Lines of
Symmetry

Which of these tools or constructions is used to inscribe a hexagon inside a circle

An equilateral triangle has 60 degree angles. 60 degrees x 6 = 360 degrees. A hexagon has 6 sides so....

Which of these tools or constructions is needed to construct an equilateral triangle

Compass I know that apex struggle

Does the parallel postulate in Euclidean geometry work in spherical geometry

Two of the Belleville three where who

Kevin Saunderson and Derrick May

Which transformations will result in an image that maps onto itself

What Rotational symmetry is the quality a design has if it maintains all characteristics when it is rotated about a line of symmetry.

Toxic chemicals are spilled on a patch of clovers in the garden. This severely damages the nodules on the roots of the clovers. What is the most likely outcome of the damage to the nodules

A lack of nitrogen-fixing bacteria to produce the nutrients for
the clovers

A line segment that forms a right angle with another segment at its midpoint is a

Will additional fertilizers, such as nitrogen supplements damage most plants

The use of nitrogen and other fertilizers will enhance the
growth of most plants when used correctly.
