Answer:

See the graphic I made

Area of Section A = 4 *1 = 4 square centimeters

Section B = 4 * (3 + 4) = 28 sq cm

Section C = 3 * (2 + 3 + 4) = 27 sq cm

Total Area = 4 + 28 + 27 = 59 square centimeters

Step-by-step explanation:

To find the area of an octagon, you can use the formula 2 * (1 + √2) * s², where s is the length of one of the sides. If the area is given, you can solve for s and then use the formula to calculate the area.

The area of an octagon can be calculated using the formula:

Area = 2 * (1 + √2) * s²,

where s is the length of one of the sides of the octagon.

In this case, since the area is given as 0.4 m², we can solve for s.

0.4 = 2 * (1 + √2) * s²

Dividing both sides by 2 * (1 + √2) gives:

s² ≈ 0.2

Taking the square root of both sides, the length of one side is approximately 0.45 m.

To find the area, use the formula:

Area = 2 * (1 + √2) * (0.45)² ≈ 0.4 m²

Step-by-step explanation:

x² + 3 x + 40 = 0

Answer:

The answers for x^2+3x−40=0 are -8 and 5.

Step-by-step explanation:

For this problem, we are able to factor. Since 8 and 5 are both factors of 40, and since 8-5=3, we will use 8 and 5 in our binomial equation:

(x+8)(x−5)=40.

Just to prove that this is correct, let's multiply the two together: x^2−5x+8x−40=x^2+3x−40.

From here, we can use the zero product property to get our answers: x+8=0,x−5=0.

Subtract 8 from the first equation and subtract 5 from the second equation to get our answers, -8 and 5.

Therefore, if you add the weight if the textbooks (6.8) and the weight of the notebooks (3.6) it is 10.4. Therefore the answer is D. Not C.

Answer:

The answer is 176

Step-by-step explanation:

The answer is the square root of one hundred seventy-six feet.

The height of the antenna and the length of the wire form two sides of a right triangle. The distance from the base of the antenna to the point at which the wire is fixed to the ground forms the other leg.

The Pythagorean Theorem states that a squared plus b squared equals c squared, where a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse.

Let g equal the length in feet of the unknown leg.

First, apply the Pythagorean Theorem, and substitute twenty-four feet for the length of the hypotenuse and twenty feet for one of the legs.

Next, we square twenty-four and twenty.

Then, subtract four hundred from both sides to get one hundred seventy-six equals g squared.

Finally, take the square root of both sides to get the square root of one hundred seventy-six equals g.

So the distance from the base of the antenna to the point at which the wire is fixed to the ground is the square root of one hundred seventy-six feet.

(13x + 7) = (8x + 27)

We're trying to find x, so we must isolate it.

We can start by subtracting 8x from both sides.

13x - 8x + 7 = 8x - 8x + 27

Then, subtract 7 from both sides.

13x - 8x + 7 - 7 = 8x - 8x + 27 - 7

Answer:

I think that the answer is D. CB ║DE

To find the answer, all we need to is to calculate all the missing one.

So: ∠CBD = 180° - 60° - 40° = 80°

     ∠BDE = 180° - 60° - 40° = 80°

     ∠DEF = 180° - 60° - 45° = 75°

Since we have ∠CBD ≅ ∠BDE ( = 80°) and they are alternate interior angles, we can conlcude that CB ║ DE.

Answer:

D)4x + 6/(x + 1)(x - 1)

Step-by-step explanation:

A field is basically a rectangle, so to find the perimeter of our field we are using the formula for the perimeter of a rectangle

[tex]p=2(l+w)[/tex]

where

[tex]p[/tex] is the perimeter

[tex]l[/tex] is the length

[tex]w[/tex] is the width

We know from our problem that the field has length 2/x + 1 and width 5/x^2 -1, so [tex]l=\frac{2}{x+1}[/tex] and [tex]w=\frac{5}{x^2-1}[/tex].

Replacing values:

[tex]p=2(l+w)[/tex]

[tex]p=2(\frac{2}{x+1} +\frac{5}{x^2-1})[/tex]

Notice that the denominator of the second fraction is a difference of squares, so we can factor it using the formula [tex]a^2-b^2=(a+b)(a-b)[/tex] where [tex]a[/tex] is the first term and [tex]b[/tex] is the second term. We can infer that [tex]a=x^2[/tex] and [tex]b=1^2[/tex]. So, [tex]x^2-1=(x+1)(x-1)[/tex]. Replacing that:

[tex]p=2(\frac{2}{x+1} +\frac{5}{x^2-1})[/tex]

[tex]p=2(\frac{2}{x+1} +\frac{5}{(x+1)(x-1})[/tex]

We can see that the common denominator of our fractions is [tex](x+1)(x-1)[/tex]. Now we can simplify our fraction using the common denominator:

[tex]p=2(\frac{2(x-1)+5}{(x+1)(x-1)} )[/tex]

[tex]p=2(\frac{2x-2+5}{(x+1)(x-1)} )[/tex]

[tex]p=2(\frac{2x+3}{(x+1)(x-1)} )[/tex]

[tex]p=\frac{4x+6}{(x+1)(x-1)} [/tex]

Given that radius of the circle = 10

Using π, we need to find about which equation expresses the ratio of the circumference of the circle to the circle's diameter.

diameter of the circle = 2(radius) = 2(10)=20

circumference of the circle = 2 π r = 2 π (10)  = 20 π

then ratio of the circumference of the circle to the circle's diameter is given by: [tex]\frac{circumference\ }{diameter}=\frac{20\pi}{20}=\pi[/tex].

the first question is B

and I am very sorry i don't know the second question

Answer:

C, B

Step-by-step explanation:

The interior angle of a regular polygon is:

θ = (n - 2) × 180° / n

So a pentagon with 5 sides has an interior angle of:

θ = (5 - 2) × 180° / 5

θ = 108°

If we draw a line from the bottom left corner to the center, we get a right triangle.  Using tangent, we can say:

tan (108°/2) = a / (7.6/2)

tan (54°) = a / 3.8

a = 3.8 tan (54°)

a = 5.2

Answer C

If the interior angle is 144, then the number of sides is:

144 = (n - 2) × 180 / n

144n = 180n - 360

360 = 36n

n = 10

The number of students attending the camp that summer is 380 students

Step-by-step explanation:

There are four counselors for every fifty seven students

There are three teachers for every five counselors

Ms. Rifkin asked all 16 teachers present at the camp to attend a

teachers meeting

To solve this question we will use the ratio

The given is:

1. 4 counselors for every 57 students

2. 3 teachers for every 5 counselors

3. There are 16 teachers

At first let us find the 16 teachers are for how many counselors

∵ 3 teachers : 5 counselors

∵ 16 teachers : x counselors

∴ [tex]\frac{3}{5}=\frac{16}{x}[/tex]

By using cross multiplication

∴ 3x = 16 × 5

∴ 3x = 80

Divide both side by 3

∴ x = [tex]\frac{80}{3}[/tex]

Then let us find the [tex]\frac{80}{3}[/tex] counselors are for how many students

∵ 4 counselors : 57 students

∵ [tex]\frac{80}{3}[/tex] counselors : y students

∴ [tex]\frac{4}{57}=\frac{80/3}{y}[/tex]

By using cross multiplication

∴ 4y = 57 × [tex]\frac{80}{3}[/tex]

∴ 4y = 1520

Divide both sides by 4

∴ y = 380 students

Answer:

D. [tex]F(x)=(x+4)^2-5[/tex]

Step-by-step explanation:

The parent function is [tex]G(x)=x^2[/tex].

This function has its vertex at the origin (0,0).

When this function is shifted down 5 units and to the left 4 units, then its new vertex will be at (-4,-5)

The vertex form of the equation is given by;

[tex]F(x)=a(x-h)^2+k[/tex] where (h,k)=(-4,-5) is the vertex and a=1 because of the parent function.

Hence its equation is

[tex]F(x)=(x+4)^2-5[/tex]

Answer:

Option C

Step-by-step explanation:

A function g(x) = x² has been given as the parent function.

This function then shifted 5 units down.

Translated  function formed will be f(x) = x² - 5

Further this graph has been shifted 4 units to the left then the function will become

f(x) = [x - (-4)]² - 5

f(x) = (x + 4)² - 5

Therefore, option C is the answer.

Answer:

P = 21%

Step-by-step explanation:

We look for the percentage of employees who are not more than 30 years old.

This is:

[tex]P = \frac{x}{n} *100\%[/tex]

Where x is the number of new employees who are not over 30 years old and n is the total number of new employees.

We do not know the value of x or n. However, the probability of randomly selecting an employee that is not more than 30 years old is equal to [tex]P = \frac{x}{n}[/tex]

Then we can solve this problem by looking for the probability that a new employee is not more than 30 years old.

This is:

[tex]P(X< 30)[/tex]

Then we find the z-score

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

We know that:

μ = 38 years

[tex]\sigma = 10[/tex] years

So

[tex]Z = -0.8[/tex]

Then

[tex]P (X<30) = P (\frac{X- \mu}{\sigma} < \frac{30-38}{10})\\\\P (X<30) = P(Z<-0.8)[/tex]

By symmetry of the distribution

[tex]P(Z<-0.8)=P(Z>0.8)[/tex]

Looking in the normal standard tables

[tex]P(Z>0.8)=0.211[/tex]

Finally P = 21%
