Dominik [7]

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.)

Eva is making a pattern using these shapes can you arrange Evas shapes to make a symmetrical pattern
ratelena [41]

Answer:

pyramid, cone, sphere, cube

Step-by-step explanation:

A symmetrical pattern is one that is arranged in such a way that there is a progressive repetition of a pattern. Each pattern formed is the same with respect to each other.

Eva could form series symmetrical patterns with the shapes he has, which depends on the arrangement of the shapes to form desired pattern.

One simple pattern to be formed is;

pyramid, cone, sphere, cube

pyramid, cone, sphere, cube

pyramid, cone, sphere, cube

pyramid, cone, sphere, cube.

Thus, this would generate four symmetrical continuous patterns.

pyramid, cone, sphere, cube : pyramid, cone, sphere, cube : pyramid, cone, sphere, cube : pyramid, cone, sphere, cube.

Debbie needs to fill juice-cups for her little brother's birthday party. There are 20 juice-cups and each juice-cup holds 10 flu
Vinvika [58]
Number of juice cups mentioned in question = 20
Quantity of juice that each juice cup can hold = 10 fluid ounces
Quantity of fluid ounces that
20 juice cups require = 20 * 10 fluid ounces
                                  = 200 fluid ounces.
Now
32 fluid ounces = 1 quart
Then
200 fluid ounces = 200/32 quart
                           = 6.25 quart
Again
4 quart = 1 gallon
So
6.25 quart = 6.25/4 gallon
                 = 1.56 gallon
So we see that 1.56 gallon of juice is required by Debbie. As the juice comes in 1 gallon bottles, Debbie needs to order 2 bottles of juice.
