The length of each side of a regular pentagon

a)6.4cm

b) 32cm

a) A pentagon is 6.4cm to 1 decimal place it can see that the answer.

b) A pentagon has 5 sides.

The Pentagon was originally intended to be built on ground that had five sides surrounded by roadways, therefore the architects created a five-sided structure. The Pentagon serves as the Department of Defense of the United States' administrative center. During World War II, it was built on an accelerated schedule.

Any five-sided polygon or 5-gon is referred to as a pentagon in geometry (from the Greek word pente meaning five and gonia meaning angle). In a straightforward pentagon, the interior angles add up to 540°. A pentagon could be straightforward or self-intersect. A pentagram is a self-intersecting regular pentagon (sometimes known as a star pentagon).

Does 3 4 5 make a right triangle WILL GIVE 30 POINTS

Answers

True

The three internal angles of a 3-4-5 right triangle are 36.87 °, 53.13 °, and 90 °. As a result, a 3 4 5 right triangle is a scalene triangle since the lengths and internal angles of all three sides differ.

Remember that a 3-4-5 triangle does not necessarily imply that the ratios are 3: 4: 5; it might be any common component of these numbers. A 3-4-5 triangle, for example, can alternatively adopt the following shapes:

Answers

Using the normal distribution, the z-score of the height of a women 5.5 feet tall is 0.51.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

Considering that each feet has 12 inches, the parameters are given as follows:

[tex]X = 5.5 \times 12 = 66, \mu = 64.1, \sigma = 3.7[/tex]

Hence the z-score is found as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (66 - 64.1)/3.7

Z = 0.51

Consider the following polygon. Determine the measure of both angles A and B. Show your work. (Note: image is not drawn to scale)

Answers

Considering the sum of the internal angles of the polygon, it is found that the measures of the angles A and B are given as follows;

Angle A: 119º.Angle B: 93º.

What is the sum of the internal angles of a polygon?

The sum of the internal angles of a polygon with n vertices is given by the following equation:

S = (n - 2) x 180º.

For this problem, the polygon has 6 vertices, hence n = 6 and the sum is given by:

S = (6 - 2) x 180º = 720º.

Considering each internal angle, we can solve for x as follows:

13x + 2 + 16x + 7 + 88 + 155 + 170 + 95 = 720

29x + 517 = 720

29x = 203

x = 203/29

x = 7.

Then the measures are given as follows:

Angle A: 16 x 7 + 7 = 119º.Angle B: 13 x 7 + 2 = 93º.

A rectangular plate with dimensions 5 cm by 3 cm must have a length 0.25 cm above or below 5 cm. Use the solution to the equation |x − 5| − 0.25 = 0 to find the minimum and maximum area, in sq. cm, of the plates

Minimum:
Maximum:

Answers

From the calculations; the minimum area is 14.25 cm^2 and the maximum area is 15.75 cm^2

What is area of rectangle?

We define the area as the product of length of the rectangle and width of the rectangle. We can give the unit of the area as square units. The area is the measure of the plane that has been covered by an object.

We have;

size of rectangular plate = 5 cm by 3cm.

Range of length = 0.25 of 5 cm

The minimum and maximum area are;

We can now formulate the following to solve the problem;

5 - 0.25 ≤ L ≤ 5 + 0.25

4.75 ≤ L ≤ 5.25

Area of rectangle = Length × Width.

Width = 3

minimum length = 4.75

maximum length = 5.25

minimum length

= 4.75 * 3

= 14.25 cm^2

maximum length

= 5.25 * 3

= 15.75 cm^2

We now obtain the minimum area as 14.25 cm^2 and the maximum area as 15.75 cm^2

I use a prime factor analysis (identify all the prime factors).

72 :

36 ÷ 2 = 18

18 ÷ 2 = 9

9 ÷ 2 no

9 ÷ 3 = 3

3.71 thousand in ordinary notation

Answers

3.71 thousand is written as 3,710

In figures, the digits in 3.71 thousand are separated with commas and written as 3,710.

The number 1 thousand in numbers is 1000 . Therefore, if we want to find x thousand in number form, we want to find x copies of 1000 in number form. To do this, we simply multiply x by 1000.

x thousand = x × 1000

This gives that to find 3.71 thousand in numbers, we multiply 3.71 times 1000.

3.71 × 1000 = 3710

If we want to write 3.71 thousand in words, then it will be written as

three thousand seven hundred ten.

Therefore, 3.71 thousand as a number is 3710 and It has 1 zeros.
