Answer: [tex]A=539\pi /16=105.8m^2[/tex]

Step-by-step explanation:

Think of the white circle being on top of a larger shaded circle. You were given the diameter of this larger shaded circle. And, you were also secretly given the diameter of the inner white circle. If you find the area of the white circle, and subtract it from the area of the shaded circle, you will find the area of the shaded region.

Beginning with the area of the shaded circle. The diamater is 21 meters, while the radius is 21/2 meters. Therefore, the area is:

[tex]A=\pi r^2[/tex]

[tex]A=\pi (21/2)^2[/tex]

[tex]A=441\pi /4[/tex]

Moving on to the white circle. The diameter would be 21 meters with 3.5 meters subtracted from it:

[tex]d=21-3.5=17.5=35/2[/tex]

Therefore the radius is:

[tex]r=(35/2)/2=35/4[/tex]

Which means the area would be:

[tex]A=\pi r^2[/tex]

[tex]A=\pi (35/4)^2[/tex]

[tex]A=1225\pi /16[/tex]

Therefore the shaded region is:

[tex]A=441\pi /4-1225\pi /16[/tex]

Get common denominators:

[tex]A=1764\pi /16-1225\pi /16[/tex]

[tex]A=539\pi /16[/tex]

Answer:

8%

Step-by step explanation:

We are given:

The formula to determine the percentage of unemployed workers in the total workers, we need to divide the number of unemployed works by the total workers in the labor force. Then, multiply the quotient by 100 to obtain the percentage of unemployed workers.

Formula:

[tex]\dfrac{\text{Unemployed workers}}{\text{Total workers} } \times 100 = \text{Percentage of unemployed workers}[/tex]

Substitute the given values into the formula to determine the percentage of unemployed workers in the labor force.

[tex]\implies \dfrac{\text{24,000}}{\text{300,000} } \times 100 = \text{Percentage of unemployed workers}[/tex]

Now, simplify the equation.  The easiest way to simplify the equation is to temporially ignore the "100".

[tex]\implies \dfrac{\text{24,000}}{\text{300,000} } = \text{Percentage of unemployed workers}[/tex]

Then, cancel the "0's" on the L.H.S. This is a good way to simplify the equation on the L.H.S

[tex]\implies \dfrac{\text{24}}{\text{300} } = \text{Percentage of unemployed workers}[/tex]

Don't forget to multiply the result by 100 as it was temporaily hidden.

[tex]\implies \dfrac{\text{24}}{\text{300} } \times 100= \text{Percentage of unemployed workers}[/tex]

Let 100 be 100/1. Thus, our equation will be:

[tex]\implies \dfrac{\text{24}}{\text{300} } \times \dfrac{100}{1} = \text{Percentage of unemployed workers}[/tex]

Multiply the numerator with the numerator and the denominator with the denominator.

[tex]\implies \dfrac{24 \times 100}{\text{300} \times 1} } = \text{Percentage of unemployed workers}[/tex]

[tex]\implies \dfrac{2400}{\text{300} } = \text{Percentage of unemployed workers}[/tex]

Cancel the "0's" on the L.H.S to make it easier to simplify.

[tex]\implies \dfrac{2400}{\text{300} } = \text{Percentage of unemployed workers}[/tex]

[tex]\implies \dfrac{24}{\text{3} } = \text{Percentage of unemployed workers}[/tex]

[tex]\implies 8 = \text{Percentage of unemployed workers}[/tex]

Thus, 8% of the workers are unemployed workers.

Answer:

  v = 13

Step-by-step explanation:

The diagonals of a parallelogram bisect each other, so AB ≅ AD. This relation gives rise to an equation we can solve for v.

  2v -3 = 6v -55

  52 = 4v . . . . . . . . . add 55-2v to both sides

  13 = v . . . . . . . divide by 4

The value of v is 13 in this parallelogram.

We have been asked to find the length , perimeter and area of square .

First let's calculate the side of square .

Using Formulae

[tex] \boxed{\bf \:Diagonal_{(Square)} \: = side \sqrt{2}}[/tex]

On substituting the value in above formula we obtain

[tex] \qquad\longrightarrow\sf \:4 \sqrt{2} = side \sqrt{2} \\ \\ \\ \qquad\longrightarrow\sf \:4 \cancel{\sqrt{2}} = side \cancel{ \sqrt{2}} \\ \\ \\ \qquad\longrightarrow\sf \:side \: = 4 \: cm[/tex]

Therefore,

Finding the perimeter of square.

[tex] \boxed{\bf \: Perimeter_{(Square)} = 4 \times side}[/tex]

Substituting the value we obtain

[tex]\qquad\longrightarrow\sf \:Perimeter_{(Square)} \: = 4 \times 4 \\ \\ \\ \qquad\longrightarrow\sf \:Perimeter_{(Square)} = 16 \: cm[/tex]

Therefore,

Finding the area of square .

Answer:

26

Step-by-step explanation:

simply count the number of times the team scored more than 50 points by looking at the graph.

the team scored 51-60 points 11 times, 61-70 points 12 times and 71-80 points 3 times.

so the team scored more than 5 points a total of 11 + 12 + 3 = 26 times

Answer:

26

Step-by-step explanation:

Game scores above 50 points can be represented by the last three boxes to the left. To find the total number of times this happened, add up the values measured by the y-axis:

51-60 = 11 games

61-70 = 12 games

71-80 = 3 games

11 + 12 + 3 = 26

Answer:

12 girls

Step-by-step explanation:

Boys to girls ratio= 1:2

Thats means there are (1+2) 3 total parts.

So [tex]\frac{36}{3}[/tex]=12

Each part is 12 so

boys is 12*2= 24 boys

Girls id 12*1= 12 girls

Answer:

12

Step-by-step explanation:

Total number of students in class ⇒ 36

Given that,

The number of boys is twice the number of girls.

First, let us make an expression to find the number of girls.

For that, let the number of girls be x.

Number of girls ⇒ x

Number of boys ⇒ 2x

Total number of pupils ⇒ x + 2x

So,

x + 2x  = 36

3x = 36

Divide both sides by 3.

x = 12

Therefore, there are 12 girls and 24 boys in the class.

Answer:

46°

Step-by-step explanation:

Points of note

Solving

Answer:

46°

Step-by-step explanation:

Complementary angles

Two angles whose measures sum to 90°

In a right triangle, the angle opposite the hypotenuse is always 90°.  

The interior angles of a triangle sum to 180°, therefore the other two angles are complementary angles since their sum is always 90°.  

So we can label one angle as [tex]x[/tex] and the other as [tex](90-x)[/tex].

The side opposite angle [tex]x[/tex] is the side adjacent to angle [tex](90-x)[/tex].

Therefore, using trig ratios, we can say that [tex]\sin(x) = \cos(90-x)[/tex]

So, if [tex]x=44[/tex] then:

[tex]\implies \sin(44) = \cos(90-44)=\cos(46)[/tex]

Answer:

SA = 434 ft^2

Step-by-step explanation:

We are going to exclude the floor since we are assuming he won't paint the floor. The shed has 5 sides since we aren't going to consider the floor.

length - L

width - W

height - H

surface area - SA

H = 8 ft

L = 14 ft

W = 7 ft

To calculate the area of each side or surface of the shed,

since there are two sides/ surfaces with the same are except for the roof, we will multiply the areas by 2.

Surface area:

SA = 2 × (W×H + L×H) + L×W

SA = 2 × (7×8 + 14×8) + 14×7

SA = 434 ft^2

Step-by-step explanation:

[tex]\sf \boxed{a^m*a^n = a^{m+n}\\\\}[/tex]

[tex]\sf \left(\frac{m^{-1}m^{5}}{m^{-2}} \right)^{-3} =\left(\dfrac{m^{-1+5}}{m^{-2}}\right)^{-3}[/tex]

                 [tex]\sf = \left(\dfrac{m^4}{m^{-2}}\right)^{-3}\\\\[/tex]

[tex]\boxed{\dfrac{a^{m}}{a^{n}}=a^{m+n}}[/tex]

                    [tex]\sf = \left(m^{4-[-2]}\right)^{-3}\\\\ =\left(m^{4+2}\right)^{-3}\\\\ = \left(m^6\right)^{-3}\\\\[/tex]

[tex]\boxed{(a^{m})^n=a^{m*n}}[/tex]

                    [tex]\sf= m^{6*(-3)}\\\\ = m^{-18}[/tex]

[tex]\boxed{a^{-m}=\dfrac{1}{a^m}}[/tex]

                    [tex]\sf=\dfrac{1}{m^{18}}[/tex]

Answer:

in this problem. Not that the total number of ways of taking one or more alternative out of ...

Step-by-step explanation:

Answer:

No.

Step-by-step explanation:

Well, honestly not sure how to solve this but I'll try.

Each correct answer is giving 4 points but the probability to choose the correct one is 1/5

Each incorrect one gives -2 points and the chance to pick a wrong answer is 4/5.

Obviously, the chance to lose points is more. But is taking the risk and guessing worth it? Well, it depends on how many points the correct answer gives. If it makes up for the possible loss of points, then it is in his interest to guess, otherwise he will end up losing more than they win.

If we sum the two chances to find averagely how many points the student will get, then I guess that would be the correct answer:

4(1/5) + (-2)(4/5) = 4/5 - 8/5 = -4/5

He will get averagely -4/5 points, so I believe it isn't in his interest. It means that the points he gets don't make up for the possible loss of points if you choose answers randomly. (Wow, I'm glad teachers don't do this on tests 0_0)

This is my theory though, not sure how to go for solving this, just thinked logically. I hope this helps, but don't trust me and copy paste my answer on your test or whatever. Think if this is correct first because I'm not sure

Answer:

True

Step-by-step explanation:

limx→b [3f(x)-4g(x)]

limx→b [3f(x)-4g(x)]= limx→b [3f(x)] - limx→b [4g(x)]

= 3[limx→b f(x)] - 4[limx→b g(x)]

Since limx→b f(x) = 2 and limx→b g(x) = 10,

= 3(2)-4(10)

= -34
