Answer:
SSS
Step-by-step explanation:
- square
- regular pentagon
- regular hexagon
- regular octagon
- regular nonagon
- regular dodecagon
The regular polygons could be used to make regular and semi-regular tessellations are equilateral triangle, square and regular hexagon. Therefore, the correct answers are A, B and D.
A regular tessellation is tessellation made up by using only one type of regular polygon. These are made up of completely congruent regular polygons all that connecting vertex to vertex.
Regular polygons have congruent straight sides. When we slide or rotate a regular polygon, the side of the original figure and the side of its translation will match.
Equilateral triangles, squares and regular hexagons are the only regular polygons that tessellate. Therefore, there are only three regular tessellations.
Therefore, the correct answers are A, B and D.

G. regular dodecagon
Step-by-step explanation:
Answer: 8/10
Step-by-step explanation: Using the place value chart, we can see that 0.8 means eight-tenths which can be written as the fraction 8/10. Since 8/10 is not in lowest terms, we need to divide both the numerator and denominator by the greatest common factor of 8 and 10 which is 2 to get 4/5.
Therefore, 0.8 can be written as the fraction 8/10.
The decimal number 0.8 in the simplest fraction form will be 4/5.
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of a numerator and a denominator.
The decimal number is given below:
⇒ 0.8
Multiply and divide the expression by 10. Then we have
⇒ 0.8 x 10 / 10
⇒ 8 / 10
⇒ 4 / 5

Answer:
angle 4 is 31
angle 5 is 59.
Step-by-step explanation:
M<4 and M<5 add up to a right angle which is 90 degrees . so you put it in a equation form.
2x-5+4x-13=90
rearrange it
2x+4x-5-13=90
6x-18=90
add 18 on both sides
6x=108
divide 6 from both sides
and you get x= 18
Plug in x for angle 4 =2(18)-5 = 31
plug in x for angle 5 = 4(18)-13 = 59
The fraction of students in the class who are men can be calculated by dividing the number of men by the total number of students in the class. Given that there are 18 men in a class of 32 students, the fraction of men in the class is 9/16.
This question is dealing with the concept of fractions in mathematics. From the information given, we know that there are 32 students in the class and 18 out of those are men. To find the fraction of the class that is men, we divide the number of men by the total number of students in the class. This can be expressed as follows:
Number of men / Total number of students = Fraction of the class that are men.
By substituting the given figures into the formula we get:
18 / 32 = 9/16.
Therefore, 9/16 of the students in the class are men. This fraction can be further simplified by dividing both the numerator and denominator by the greatest common divisor.
