Answer: He will need 700 pieces of wood.
Step-by-step explanation: Divide the total by how many square feet one piece of wood will cover, so 3,500/5, and you'll get 700.
Hope this helps.
4(2x raise to power 2-4-7x)
Step-by-step answer:
This is a regular heptagon, means it has 7 <em>congruent</em> sides and 7 <em>congruent </em>vertex angles.
To work with polygons, there is a very important piece of information that you must know to solve the majority of related problems.
This is:
sum of exterior angles of polygons = 360 degrees.
If you don't remember the 360 degrees, think of the sum of exterior angles of an equilateral triangle, which is 3*(180-60)=3*120=360! It works!
For a regular heptagon, c = 360/7=51.43 degrees approx.
This means that each vertex angle measures
vertex angle = 180-c
So since 2d+the vertex angle = 360, we have
2d+(180-c)=360
solve for d:
2d=360-(180-c)=180+c
d=(180+c)/2=90+c/2=115.71 degrees. (approx.)
Answer:
76.7
Step-by-step explanation:
11.3(3) + 10.7(4) = __ + 42.8
Multiply values
33.9 + 42.8 = __ + 42.8
The missing value is 33.9!
42.8 + 33.9 = 76.7
3. Trapezoid- only one pair of parallel sides
4. Parallelogram- opposite sides are parallel and equal in length and opposite angles are equal
5. Rhombus- all sides have an equal length, opposite sides are parallel, and opposite angles are equal
6. Kite- have two pairs of sides, each made up of adjacent sides that are equal in length. Angles are equal where pairs meet.
7. Isosceles Trapezoid- have a pair of opposite parallel sides that are equal in length.
