Answer:

6ft for 30°

8.5ft for 45°

10.4ft for 60°

Step-by-step explanation:

12(sin 30°)=x

x=6

12(sin 45°)=x

x=8.5

12(sin 60°)=x

x=10.4

By using right angle trigonometry and the cosine function (x = L cos θ), we find that a 12-ft ladder reaches 10.4 ft, 8.5 ft and 6 ft up a wall when it is leaned at 30°, 45° and 60° respectively.

The problem described here involves the use of right angle trigonometry, specifically the use of the cosine function. In order to determine how high up the wall the ladder reaches at an angle of 30°, 45° and 60°, we can use the formula: x = L cos θ.

Firstly, let's calculate the height at 30 degrees (θ = 30°). We know that cos 30° = √3/2, so we substitute into the formula: x = 12ft * √3/2 which approximately equals 10.4 ft.

Next, for 45 degrees (θ = 45°), cos 45° = √2/2. Substituting into the formula: x = 12ft * √2/2 = 8.5 ft.

Finally, for 60 degrees (θ = 60°), cos 60° = 1/2. Therefore, x = 12ft * 1/2 = 6ft). So, the ladder reaches 10.4 ft up the wall when the angle is 30°, 8.5 ft when the angle is 45°, and 6 ft when the angle is 60°.

Answer:

Yes , i thinks so because have letter and the result is perfect and have two statement.

To find the dimensions of the rectangle, express its length in terms of its width as 'width + 6'. Substitute this in the formula for perimeter and solve to get width = 5 feet and length = 11 feet.

The problem stated relates to the geometric concept of perimeter and involves a bit of algebra. First, remember that the formula for the perimeter of a rectangle is 2(length + width). If the total perimeter is 32 feet, and the length is 6 feet longer than the width, we can describe the length as 'width + 6'.

Substitute these into the perimeter formula: 2((width + 6) + width) = 32. Simplify this to 2(width + width + 6) = 32, then simplify further to 2(2width + 6) = 32. Divide both sides by 2 to get 2width + 6 = 16. Solving for 'width', we get width = 5 feet. Therefore, the length (which is width + 6) would be 5 + 6 = 11 feet.

Answer:

As we can see in the picture, we already knew 4 out of 6 sides of the figure so we need to find the other sides.

So the first missing side (the one near the 3 m one) should be:

7 - 4 = 3 (m)

The second missing side (the one near the 4m one) should be:

6 - 3 = 3 (m)

Now that we know all of the side lengths of the figure, the perimeter of the figure will be:

7 + 3 + 3 + 3 + 4 + 6 = 26 (m)

5. 35/5=5R/5

7= R

6. Q/2 (2) = 6 (2)

Q=12

Answer:

Step-by-step explanation:

1) 14-7 = 7 = k

2) 21 + W = 36  →  W = 36 - 21  → W = 25

3) -5 = G + 3.  Add 5 to both sides, obtaining G = 8.

4) 2b = 12.  Div. both sides by 2:  b = 6

5) 35 = 5R.  Div. both sides by 5:  7 = R

6) Q/2 = 6; Mult both sides by 2: Q = 12

A.  The two triangles.

Step-by-step explanation:

Isometry can be divided into two words: iso = same and metry = measure

So, isometry means "same measure".

In this case, that means the transformation didn't change the measures of the object.

In B, they kept the same shape, but not the same side.

x + y = 28

1.68x + 2.44y = 54.64

Step-by-step explanation:

Let x = paperback books and y = hardback books

x+y =28

We know that paperbacks cost 1.68 and hardback cost 2.44

1.68x + 2.44y = 54.64

We have 2 equations and 2 unknowns

Answer:

Option A. (6,2)

Step-by-step explanation:

Then the region of inequality are all values of y that are less than [tex]f (x) = x-3[/tex]

In other words, the points belonging to the inequality are all those that lie below the line.

To find out which point belongs to this region substitute inequality and observe if it is satisfied

Answer:

120 floor seats, 80 stadium seats

Step-by-step explanation:

use extreme values

if all were floor seats, then cost would be 32*200, or 6400

6400-5440=960

32-20=12

960/12=80

200-80=120

120 floor seats and 80 stadium seats were sold.

Let's designate F as the number of floor seats and S as the number of stadium seats.

Given :

F + S = 200 (Equation for the total number of tickets)

32F + 20S = 5440 (Equation for the total sales amount)

We can use substitution or elimination to solve this system. If we multiply the first equation by 20 to get

20F + 20S = 4000

and subtract it from the second equation, we get:

12F = 1440

F = 120

We found the number of floor seats sold. We can then substitute F back into the first equation to find the number of stadium seats:

120 + S = 200

S = 80.

So, 120 floor seats and 80 stadium seats were sold.

Answer:

  about 35.4 yards

Step-by-step explanation:

Make use of the formula for the area of a square and solve for the side length. The area (A) of a square of side length s is given by ...

  A = s²

You are given A and asked to find s. So you have

  1255 yd² = s²

To find s, you take the square root of both sides of the equation.

  √(1255 yd²) = √(s²)

  35.426 yd ≈ s . . . . . the square root of 1255 is irrational, so we have shown an approximation rounded to 3 decimal places.

Each side of the field is about 35.4 yards long.

Answer:

  x = 24

Step-by-step explanation:

The segments on either side of an angle bisector are proportional:

  (x +4)/44.8 = 35/56

  x +4 = 44.8·(35/56) = 28 . . . . multiply by 44.8

  x = 24 . . . . . subtract 4

Answer:

The value of x is 24.

Step-by-step explanation:

Given information: In ΔGHE, ED is angle bisector, EG=44.8 millimeters, GD=(x+4) millimeters, DH=35 millimeters, and EH=56 millimeters.

According to the angle bisector theorem, an angle bisector divide the opposite side into two segments that are proportional to the other two sides of the triangle.

In ΔGHE, ED is angle bisector, By using angle bisector theorem, we get

[tex]\frac{GD}{DH}=\frac{EG}{EH}[/tex]

[tex]\frac{x+4}{35}=\frac{44.8}{56}[/tex]

Multiply both the sides by 35.

[tex]x+4=\frac{44.8}{56}\times 35[/tex]

[tex]x+4=28[/tex]

Subtract 4 from both the sides.

[tex]x=28-4[/tex]

[tex]x=24[/tex]

Therefore the value of x is 24.

Answer:

1. 37

2. 25

Step-by-step explanation:

In order to find a percentile of a given number set, you must first put the values in ascending order:

18, 20, 22, 25, 26, 36, 37, 41, 45, 50

70% = 0.7

Since there are 10 numbers in the set, we'll multiply 10 by 0.7

10 × 0.7 = 7

So we are going to look at the seventh number in the set.

18, 20, 22, 25, 26, 36, 37, 41, 45, 50

1     2     3    4    5    6    7    8    9   10

The seventh number in the set is 37.

We're going to do the same for finding the 40th percentile:

40% = 0.4

10 × 0.4 = 4

Finding the fourth number in the set...

18, 20, 22, 25, 26, 36, 37, 41, 45, 50

1     2     3    4    5    6    7    8    9   10

... We get 25

And those are you answers, 37 and 25.

Answer:

  50 cm

Step-by-step explanation:

Consider isosceles triangle AEF in the attachment. Point B is the center of the incircle, and it divides altitude AC into segments having the ratio 12:5.

Triangle ABD is similar to triangle AEC by AA similarity. (Angle A is the same for both right triangles. Then the ratio of hypotenuse to short leg will be the same for each. In triangle ABD, that ratio is 12:5, as given by the problem statement. Since we know AE = 60 cm, also from the problem statement, we know that ...

  AB/BD = AE/EC

  12/5 = 60 cm/EC

so ...

  EC = (60 cm)·(5/12) = 25 cm

Base length EF is twice that, or 50 cm.

Step-by-step explanation:

Consider right triangle HospitalSchoolSupermarket. In this triangle:

The shortest road from the main entrance of the supermarket to the highway that connects the school and hospital will be the height drawn from the point Supermarket to the hypotenuse HospitalSchool.

Let the length of this road be x mi and the distance from School to point A be y mi. Use twice the Pythagorean theorem for right triangles Supermarket SchoolA and SupermarketHospitalA:

[tex]\left\{\begin{array}{l}x^2+y^2=8.82^2\\ \\x^2+(14.7-y)^2=11.76^2\end{array}\right.[/tex]

Subtract from the second equation the first one:

[tex]x^2+(14.7-y)^2-x^2-y^2=11.76^2-8.82^2\\ \\14.7^2-2\cdot 14.7y+y^2-y^2=11.76^2-8.82^2\\ \\-29.4y=11.76^2-8.82^2-14.7^2\\ \\29.4y=155.5848\\ \\y\approx5.24\ mi[/tex]

Answer:

(8,0)

Step-by-step explanation:

The equation that models the path traced by the ball is

[tex]h(x)=-8x^2+64x[/tex]

To find the point at which the ball hit the ground, we must equate the function to zero.

[tex]-8x^2+64x=0[/tex]

Factor;

[tex]-8x(x-8)=0[/tex]

[tex]-8x=0,(x-8)=0[/tex]

This implies that;

x=0,x=8,

At x=0, the ball was not yet kicked.

So we take x=8, to be the time the ball hit the ground.

We substitute x=8 into the function to get;

[tex]h(8)=-8(8)^2+64(8)=0[/tex]

Hence the point at which the ball hit the ground is (8,0)
