The area over which the signal is transmitted are: a.[tex]\pi[/tex] b. [tex]25\pi[/tex] c. CB transmits 25 times more signal to walkie talkie.

When two quantities of the same units are compared, the ratio shows how much of one quantity is included in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, while part to part ratio is the other.

The area of the circle is given by the formula:

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

For the walkie-talkie the signal is received up until 1 mile. Substitute the value of r = 1.

[tex]A _1= \pi (1)^2\\\\A_1 =\pi[/tex]

For the CB radio the signal is received up until 5 miles. Substitute the value of r = 5.

[tex]A_2 = \pi (5)^2\\\\A_2= 25 \pi[/tex]

a. The area over which a walkie-talkie can transmit its signal is [tex]\pi[/tex] miles.

b. The area over which a CB radio signal can transmit its signal is [tex]25\pi[/tex] miles.

c. The ratio of the transmitted signals are:

[tex]\frac{CB}{WT} = \frac{25\pi}{\pi} \\\\CB = 25 (WT)[/tex]

Option (B) is correct.

What is the triangle similarity test?

The triangle similarity test is a method used to determine whether two triangles are similar or not. Similar triangles are triangles that have the same shape but different sizes. They are similar if their corresponding angles are congruent and their corresponding sides are in proportion. There are several ways to test for similarities, such as the side-side-side (SSS) test, the angle-angle-side (AAS) test, and the side-angle-side (SAS) test.

In the given figure, triangle KLM is similar to Triangle ORS.

and by the property of similar triangles, sides of similar triangles are in proportion:

The rectangular pool has a width of 80 feet and a length of 68 feet. The area is 640 square feet and the length is 12 feet shorter than the width.

1. 640 divided by 12 = 53.33

2. 53.33 + 12 = 65.33

3. Width = 65.33 feet

4. Length = Width - 12 = 65.33 - 12 = 53.33 feet

The area of the rectangular pool is 640 square feet. To find the width, we divide 640 by 12 because the length is 12 feet shorter than the width. 640 divided by 12 gives us 53.33. We add 12 to this number to get the width of the pool, which is 65.33 feet. To find the length, we subtract 12 from the width, which gives us 53.33 feet. Therefore, the width of the pool is 65.33 feet and the length is 53.33 feet. The area of the pool is 640 square feet and the length is 12 feet shorter than the width.

The values within the range of the piecewise-defined function are

y = -6,  y = -4, y = 1 and y = 3.

A piecewise function, or f(x), is a function with various definitions at various intervals of x. A piecewise function's graph is divided into sections that each correspond to one of its definitions. A very good illustration of a piecewise function is the absolute value function.

Given f(x) = 2x + 3,   if x < -3

f(x) = x, if  x = -3

f(x) = -x - 2, if  x > -3

the function will be at x ≤ -3 and x ≥ -3

We now wish to determine which values fall within this function's range. Keep in mind that the set of possible outputs from a function constitutes its range.

The range of the first part of the function f(x) = 2*x + 2 has an upper bound at x = -3

f(-3) = 2*-3 + 2 = -6 + 2 = -4

Then the range of the first part is (-∞, -4)

Notice that the actual value -4 belongs to the range because x is smaller than and equal to -3.

The range of the second part has a lower bound for x = -3, the lower bound is:

f(-3) = -(-3) - 2 = 1

Then the range of this part is (1, ∞)

Then the range of the piecewise function is:

(-∞, -4) U (1, ∞)

and including -4 and 1

y = -6,  y = -4

y = 1,     y = 1

Hence values in the range are y = -6,  y = -4, y = 1, and y = 3.

A magnitude 8 on the Richter scale is 100 times more ground shaking than one that measures 6 on the Richter scale.

The magnitude of an earthquake is determined using the logarithm of the amplitude (height) of the largest seismic wave, calibrated to a scale by the seismometer. The Richter scale was originally developed to measure the magnitude of moderate earthquakes (magnitude 3 to magnitude 7) by assigning numbers so that the magnitude of one earthquake can be compared to another. We have, maganitude of two earthquakes, 8 and 6 Let the magnitude of first earthquake be A and second be B . So, A = 8 , B = 6 , to compare two earthquakes in terms of shaking, you subtract one magnitude from the other and raise 10 to that power, 10⁽ᴹ ⁻ ᴹ´⁾

The length of the rectangle is 18 feet and width is 8 feet .

The perimeter of a rectangle is the sum of the lengths of all four sides of the rectangle. It is calculated by adding twice the length and twice the width. The formula to calculate the perimeter of a rectangle is

P = 2(L + W), where P is the perimeter, L is the length and W is the width of the rectangle. In simpler terms, it is the total distance around the rectangle.

The perimeter of rectangle is given by  2 ( l + b)

where l is length of rectangle and b is width of the rectangle

given that perimeter of rectangle is 52

so 2 (l+b)= 52

=>  l+b=26  ---(i)

given l = b +10

=> l -b = 10 ---(ii)

adding equation (i) and (ii) we get :

On the Richter scale, every whole-number rise in magnitude corresponds to a 10-fold increase in observed amplitude.

An angle bisector of a triangle is a line segment that divides an angle into two congruent angles. In an equilateral triangle, all angles are congruent (60 degrees), so any line segment that divides an angle into two congruent angles is also an angle bisector.

To find the angle bisector of an equilateral triangle, you can use the following method:

Draw an equilateral triangle.

Choose an angle and draw the angle bisector from the vertex of the angle to the midpoint of the opposite side.

Since all the angles of an equilateral triangle are congruent, the angle bisector that you drew bisects any angle of the triangle.

Alternatively, you can use the following method:

Draw an equilateral triangle.

Connect the midpoint of one side of the triangle to the opposite vertex.

The segment that you drew bisects the angle of the triangle.

It is important to note that in an equilateral triangle, all medians, altitudes, angle bisectors, and perpendicular bisectors are congruent, they all divide the triangle in the same ratio, so they all meet at the same point, called the centroid, which is 2/3 of the distance from each vertex to the midpoint of the opposite side.

The third stanza of Wilfred Owen's poem "Dulce et Decorum Est" is only two lines long, but it creates a gripping and powerful emotional impact.

Through the use of enjambment, the abrupt transition of the first line to the second creates an unsettling feeling, as if the speaker is struggling to express their thoughts and emotions. The imagery of the gas masks and the vivid depiction of the soldiers' "blood-shod" feet further amplify this emotion, providing a stark contrast to the ideals of glory and honor that the poem's title alludes to. This imagery also serves to evoke a feeling of despair and hopelessness, as the reader is confronted with the harsh realities of war.

No, All 30-60-90 triangles are right triangles, but not all right triangles are 30-60-90 triangles.

No, not all right triangles are 30-60-90 triangles. A right triangle is a type of triangle that has one right angle (90 degrees) and two acute angles. The other two angles in a right triangle can have any measurement, they don't have to be 30-60-90 degrees.

A 30-60-90 triangle is a special type of right triangle that has specific angle measurements: one angle is 90 degrees (the right angle), one angle is 30 degrees, and one angle is 60 degrees. The ratio of the sides in a 30-60-90 triangle is also fixed, the longest side is opposite the 90-degree angle and it is always twice the length of the shortest side and the medium side is opposite the angle of 60 degrees and it's always the square root of 3 times the length of the shortest side.

For example, if a right triangle has angles of 45 degrees, 45 degrees, and 90 degrees, it is not a 30-60-90 triangle. The angles do not fit the pattern of 30-60-90 degrees.

Side length of square = -10b³ + 12

Step-by-step explanation:

Forming the equation,

→ P = 4 × side

→ P = 4a

→ [ a = P/4 ]

Now the side length of square is,

→ a = P/4

→ a = (-40b³ + 48)/4

→ a = (-40b³ ÷ 4) + (48 ÷ 4)

→ a = (-10b³) + (12)

→ [ a = -10b³ + 12 ]

Hence, side length is -10b³ + 12.

Answer:

-10b³ + 12

Step-by-step explanation:

The perimeter of a two-dimensional shape is the distance all the way around the outside.

As a square has four sides of equal length, the perimeter of a square is four times the length of one side.

Therefore, to find the expression for the side length of a square, simply divide the expression for the perimeter by 4.
