Answer:  

A 2-dimension closed figures with a number of sides is called Polygon.

If it has 7 sides it is called Heptagon,

If it has 12 sides it is called Dodecagon,

If it has 6 sides it is called Hexagon,

If it has 10 sides it is called Decagon,

If it has 8 sides it is called octagon,

If it has 5 sides it is called Pentagon,

Since, First figure has 6 sides therefore, it is a hexagon,

While, Second figure has 12 sides therefore, why it is a Dodecagon,

And, Third figure has 10 sides therefore, it is a Decagon.

Help me find the answer <br>Tan 0 and Cot O ​
vesna_86 [32]

Answer:

Step-by-step explanation:

we can say the angle is also +45° going in the clock wise direction.  so take Tan(45)= 1

Cot(45) = 1

b/c  Tan(45) = Sin(45) /Cos(45) = (\sqrt{2}/2) / (\sqrt{2}/2)   ofc that's just 1

b/c Cot(45) = Cos(45) / Sin(45) , which is the same as above 1

How should the decimal point in 34.05 be moved to determine the product 34.05×106 ?
r-ruslan [8.4K]

Answer: Six places to the right

Step-by-step explanation:

For this exercise it is important to remember that. by definition, the exponent of a number indicates the number of times you must use the same factor to multiply.

Given:

b^n

"b" is the base and "n" is the exponent.

In this case, you have the following multiplication provided in the exercise:

34.05*10^6

Notice that the base 10 has an exponent 6. This indicates the following:

10^6=10*10*10*10*10*10=1,000,000

By definition, moving the decimal point 6 places to the right (because there are six zeros), is the same as multiplying the decimal number 34.05 by 1,000,000.

  Therefore, based on the explained, when you move the decimal point six places to the right, you get the following product.

34.05*10^6=34,050,000

Anastasy [175]

Answer:

Urban area = 58.27%

Suburban area = 34.83%

Rural area = 6.9%

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Total number of women = 290

Number of women in urban area = 169

Suburban area women = 101

Rural are women = 20

So, we can calculate the percentage of number of women from each area by using following formula,

Percentage = Women in specific area ÷ total women

So, percentage of Urban area = 169 ÷ 290 = 0.5827 or 58.27%

percentage of suburban area = 101 ÷ 290 = 0.3483 or 34.83%

percentage of rural area = 20 ÷ 290 = 0.0690 or 6.9%

Pie chart for the given information is attached below.
