Step-by-step explanation:

Answer:

0.041 = 4.1%

Step-by-step explanation:

The probability the first box has a secret decoder ring is 13/62.

The probability the second box has a secret decoder ring is 12/61.

The probability of both is:

P = (13/62) (12/61)

P ≈ 0.041

As we know an identity that ;

[tex]{:\implies \quad \sf \cos \left(2\times \dfrac{\pi}{8}\right)=2\cos^{2}\left(\dfrac{\pi}{8}\right)-1}[/tex]

[tex]{:\implies \quad \sf \cos^{2}\left(\dfrac{\pi}{8}\right)=\dfrac{1+\sqrt{2}}{2\sqrt{2}}}[/tex]

Rationalizing the denominator of RHS, will yield ;

[tex]{:\implies \quad \sf \cos^{2}\left(\dfrac{\pi}{8}\right)=\dfrac{1+\sqrt{2}}{2\sqrt{2}}\times \dfrac{2\sqrt{2}}{2\sqrt{2}}}[/tex]

[tex]{:\implies \quad \sf \cos^{2}\left(\dfrac{\pi}{8}\right)=\dfrac{2\sqrt{2}+4}{8}}[/tex]

[tex]{:\implies \quad \sf \cos^{2}\left(\dfrac{\pi}{8}\right)=\dfrac{2\sqrt{2}+4}{8}}[/tex]

[tex]{:\implies \quad \sf \cos \left(\dfrac{\pi}{8}\right)=\pm \sqrt{\dfrac{2\sqrt{2}+4}{8}}}[/tex]

Now, as we know that ;

Now, setting the same [tex]{\bf{{\theta}=\footnotesize \dfrac{\pi}{8}}}[/tex]

[tex]{:\implies \quad \sf 2\sin \left(\dfrac{\pi}{8}\right)\cos \left(\dfrac{\pi}{8}\right)=\sin \left(2\times \dfrac{\pi}{8}\right)}[/tex]

[tex]{:\implies \quad \sf 2\sin \left(\dfrac{\pi}{8}\right)\cos \left(\dfrac{\pi}{8}\right)=\dfrac{1}{\sqrt{2}}}[/tex]

[tex]{:\implies \quad \sf \sin \left(\dfrac{\pi}{8}\right)\left(\pm \sqrt{\dfrac{2\sqrt{2}+4}{8}}\right)=\dfrac{1}{2\sqrt{2}}}[/tex]

[tex]{:\implies \quad \sf \sin \left(\dfrac{\pi}{8}\right)=\dfrac{\sqrt{8}}{2\sqrt{2}(\pm \sqrt{2\sqrt{2}+4})}}[/tex]

[tex]{:\implies \quad \sf \sin \left(\dfrac{\pi}{8}\right)=\pm \dfrac{1}{\sqrt{2\sqrt{2}+4}}}[/tex]

This is the required answer

Step-by-step explanation:

If you draw an altitude of the right triangle, you get that the legs are (18/2)=9 and the height (which I'll call x) and a hypotenuse of 18.

By the Pythagorean theorem,

[tex] {9}^{2} + {x}^{2} = {18}^{2} \\ 81 + {x}^{2} = 324 \\ {x}^{2} = 243 \\ x = \sqrt{243} = 9 \sqrt{3} [/tex]

Answer:

D.It is less than 0 because the addends have opposite signs and the positive addend is farther from zero.

Step-by-step explanation:

The given expression is :

When we subtract a larger number from a smaller number, we get a negative answer as mathematically we cannot subtract a larger number from smaller, so we subtract the numbers in standard format and out a negative sign in front of the answer.

Like this given expression will become : -519.70

Now, any negative number is smaller than zero.

Therefore, the correct answer is option D.

By using the definition of inverse functions, we will see that:

g(g(f(f(f(36))))) = f(36) = 25.

Two functions f(x) and g(x) are inverses if:

f( g(x) ) = x

g( f(x) ) = x

Then we can rewrite:

g(g(f(f(f(36)))))

First, we can see that:

g(f(f(f(36)))) = f(f(36))

Replacing that in our expression, we get:

g(g(f(f(f36))))) = g(f(f(36)))

And the above expression is equal to f(36), to be sure of that, let's replace:

u = f(36)

Then we can rewrite:

g(f(f(36))) = g(f(u))

And by definition, the above thing is equal to u:

g(f(u)) = u = f(36).

Finally, we conclude that:

g(g(f(f(f(36))))) = f(36) = 3*√36 + 7 = 3*6 + 7 = 25

Answer:

anything that has a numerator three times greater than its denominator. Examples: 3/1, 6/2, 9/3, 12/4, 15/5, so on.

Step-by-step explanation:

When simplifying, you divide both by the denominator and if it equals three, then the fraction is equal to three.

Answer:

Step 1. Read the problem. Draw the figure and label it with the given information. .

Step 2. Identify what you are looking for. the measure of an angle

Step 3. Name. Choose a variable to represent it. Let x= the measure of an angle.

Step 4. Translate. m\angle A+m\angle B+m\angle C=180

Write the appropriate formula and substitution

X + 4.3 + 10.6- 8.1 \end{array}

Step 7. Answer the question. The measure of the third angle is 6.8ft

The new surface area is approximately 12264.56 ft².

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

To solve this problem, we first need to calculate the original surface area of the complex solid.

The complex solid is composed of two rectangular prisms, one with dimensions 9.8 ft × 6.5 ft × 8.1 ft and one with dimensions 10.6 ft × 4.3 ft × 6.5 ft.

The surface area of the first rectangular prism is:

2(9.8 × 6.5) + 2(9.8 × 8.1) + 2(6.5 × 8.1) = 464.82 ft²

The surface area of the second rectangular prism is:

2(10.6 × 4.3) + 2(10.6 × 6.5) + 2(4.3 × 6.5) = 411.22 ft²

So the total original surface area of the complex solid is:

464.82 + 411.22 = 876.04 ft²

Now we need to find the new surface area, which is exactly 14 times the original surface area.

Therefore, we can write:

New surface area = 14 × original surface area

New surface area = 14 × 876.04

New surface area ≈ 12264.56 ft²

Thus,

The new surface area is approximately 12264.56 ft².

Answer:

C- 29.88

Step-by-step explanation:

i did it on the edge test

Answer:

There are four main types of transformations: translation, rotation, reflection and dilation. A translation moves the object without rotating it or changing its size. Reflection flips the object about a line of reflection. Rotation rotates a figure about a fixed point. Dilation changes the size of a figure without changing its essential shape. When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite. a negative angle of rotation turns the figure in a clockwise direction. Transformation can be done in a number of ways, including reflection, rotation, and translation. ~When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite.

Answer:

Area of a slice = Area of the pizza ÷ 8

Therefore the area of the pizza equals:

AreaPizza = π r^2 ( r = diameter ÷ 2)

= π 6^2

= 113.097

AreaSlice = AreaPizza ÷ 8

= 113.097 ÷ 8

= 14.137 inches squared

To the nearest square inch, each slice is 14 inches squared.

Answer:

$0.31.

Step-by-step explanation:

If 1.10 apples cost $3.50, we should divide to find the rate per apple.

1.10/3.5  ≈ 0.31

0.31 is the aproximatley answer, since there is no clear answer (at least not from my work). 0.31*70=21.70

The cost of 70 apples are 0.31.

Answer:

$150 = 4 hours,

So, in a ratio, 4 : 150

=> 150 * 4.5 : 4 * 4.5

=> 675 : 18 hours

Therefore to earn $675 at the rate of $150 for 4 hours, Fatima will need to work for 18 hours to earn $675
