The SAS (Side-Angle-Side) Congruence Rule states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the two triangles are congruent.

The SAS (Side-Angle-Side) congruence rule is a method used to determine if two triangles are congruent. This rule states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

To determine if two triangles are congruent using the SAS rule, we must first identify the two sides and the angle in one triangle that are congruent to the two sides and the angle in the other triangle. This means that they must have the same measures in terms of length and angle.

Once we have identified the corresponding sides and angles, we can use the SAS rule to determine if the two triangles are congruent. If the two sides and the angle of one triangle are congruent to the two sides and the angle of another triangle, then the two triangles are congruent.

However, if the two sides and the angle of one triangle are not congruent to the two sides and the angle of another triangle, then the two triangles are not congruent. The SAS rule is a simple and effective way to determine if two triangles are congruent.

Answer is:

The three clock sounds together for every 60 minutes.

The graph of the inequality y^2 > 0 represents all real numbers except y = 0.

The graph of the inequality y < 30 represents all real numbers less than 30.

The inequality y^2 > 0 represents all values of y where y squared is greater than 0. Since the square of any nonzero number is always positive, the solution is all real numbers except y = 0, which can be graphed as a number line with an open circle at y = 0.

The inequality y < 30 represents all values of y that are less than 30. This can be graphed as a horizontal line on the y-axis with an open circle at y = 30, indicating that 30 is not included in the solution set.

For the real-world applications, let's solve them step-by-step:

Two numbers add up to 144. One number is half the square of the other number.

Let's assume the two numbers are x and y. We have the following system of equations:

x + y = 144 (Equation 1)

x = (1/2)y^2 (Equation 2)

From Equation 1, we can solve for x in terms of y: x = 144 - y.

Substituting this into Equation 2, we get 144 - y = (1/2)y^2.

Rearranging the equation, we have: (1/2)y^2 + y - 144 = 0.

Now we can solve this quadratic equation for y. Once we find the value(s) of y, we can substitute them back into Equation 1 to find the corresponding values of x.

The squares of two numbers add to 1,156. The second number is the square root of three times the square of the first number.

Let's assume the two numbers are x and y. We have the following system of equations:

x^2 + y^2 = 1156 (Equation 1)

y = √(3x^2) (Equation 2)

Substituting Equation 2 into Equation 1, we get: x^2 + (√(3x^2))^2 = 1156.

Simplifying, we have x^2 + 3x^2 = 1156.

Combining like terms, we get 4x^2 = 1156.

Now we can solve this quadratic equation for x. Once we find the value(s) of x, we can substitute them back into Equation 2 to find the corresponding values of y.

(a) Approximately 0.22% of the runners have heart rates above 140.

(b) Approximately 27.84% of the nonrunners have heart rates above 140.

(a) The percentage of runners with heart rates above 140 can be determined by calculating the cumulative probability of the normal distribution N(104, 12.5) beyond the value of 140. We subtract the cumulative probability from 1 and multiply by 100 to obtain the percentage.

Using statistical software or a standard normal distribution table, we can find the z-score for 140 in the N(104, 12.5) distribution. The z-score formula is given by: z = (x - μ) / σ, where x is the value (140 in this case), μ is the mean (104), and σ is the standard deviation (12.5).

Substituting the values, we get: z = (140 - 104) / 12.5 = 2.88 (approximately)

Looking up the z-score in the standard normal distribution table or using software, we find that the cumulative probability for z = 2.88 is approximately 0.9978.

To calculate the percentage of runners with heart rates above 140, we subtract this cumulative probability from 1: 1 - 0.9978 = 0.0022.

Converting this to a percentage, we get 0.0022 * 100 = 0.22%.

Therefore, approximately 0.22% of the runners have heart rates above 140.

(b) To calculate the percentage of nonrunners with heart rates above 140, we follow a similar process using the N(130, 17) distribution.

Using the same z-score formula, we find the z-score for 140 in the N(130, 17) distribution: z = (140 - 130) / 17 = 0.5882 (approximately).

Looking up the z-score in the standard normal distribution table or using software, we find that the cumulative probability for z = 0.5882 is approximately 0.7216.

To calculate the percentage of nonrunners with heart rates above 140, we subtract this cumulative probability from 1: 1 - 0.7216 = 0.2784.

Converting this to a percentage, we get 0.2784 * 100 = 27.84%.

Therefore, approximately 27.84% of the nonrunners have heart rates above 140.

the base of the triangular window is 24 feet and the height is 10 feet.

Let's denote the height of the triangular window as h feet. According to the given information, the area of the window is 120 square feet.

The formula to calculate the area of a triangle is:

Area = (1/2) × base × height

In this case, we can write the equation as:

120 = (1/2) × base × h

Now, we are also given that the base of the window is 4 feet more than twice the height. So we can express the base as:

base = 2h + 4

Substituting this expression for the base into the area equation, we have:

120 = (1/2) × (2h + 4) × h

Now we can solve this equation for the height.

Multiplying both sides of the equation by 2 to remove the fraction:

240 = (2h + 4) × h

Expanding the right-hand side:

240 = 2h² + 4h

Rearranging the equation and setting it equal to zero:

2h² + 4h - 240 = 0

Now we can solve this quadratic equation. Factoring out a 2:

2(h² + 2h - 120) = 0

Factoring the quadratic expression inside the parentheses:

2(h + 12)(h - 10) = 0

Setting each factor equal to zero:

h + 12 = 0   or   h - 10 = 0

Solving these equations, we get:

h = -12   or   h = 10

Since height cannot be negative in this context, we discard the negative value. Therefore, the height of the triangular window is h = 10 feet.

Substituting the height value back into the expression for the base:

base = 2h + 4

    = 2(10) + 4

    = 20 + 4

    = 24

Therefore, the base of the triangular window is 24 feet and the height is 10 feet.

Answer:

The position of the radio is (-9, 4).

The range of the radio is 9.

Step-by-step explanation:

The equation (x + 9)^2 + (y - 4)^2 = 81 is in the form of a circle, so we can use the standard equation for a circle to find the center and radius of the circle. The standard equation for a circle is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center of the circle and r is the radius of the circle

In the equation (x + 9)^2 + (y - 4)^2 = 81, we can see that:

Therefore, the center of the circle is at (-9, 4) and the radius of the circle is 9.

The position of the source of the radio signal is at the center of the circle, which is at (-9, 4). The range of the signal is the radius of the circle, which is 9. This means that the radio signal can be received by any device within a 9-unit radius of the source.

The source of the radio signal is located at (-9, 4), and the range of the signals extends up to a distance of 9 units from the source.

The equation (x + 9)^2 + (y - 4)^2 = 81 represents the position and range of the source of a radio signal. By analyzing the equation, we can determine the position of the source and the range of the signals.

Position: The equation is in the standard form of a circle, (x - h)^2 + (y - k)^2 = r^2, where (h, k) represents the center of the circle. Comparing this with the given equation, we can see that the center of the circle is at (-9, 4). Therefore, the position of the source of the radio signal is at the coordinates (-9, 4).

Range: In the equation, the term 81 represents the radius of the circle, denoted as r. So, the range of the signals is equal to the radius, which in this case is √81 = 9 units. This means that the radio signals from the source can reach a maximum distance of 9 units from the center.

In summary, the source of the radio signal is located at (-9, 4), and the range of the signals extends up to a distance of 9 units from the source.
