The triangles are congruent by AAS (Angle-Angle-Side) and not by ASA (Angle-Side-Angle)

When the corresponding length of sides or measure of the internal angles of two or more triangles are equal, then the triangles are said to be congruent. The congruency can be expressed in terms angles, sides, or the combination of sides and angles. An example is the SAA (Side-Angle-Angle) property which implies that a side that is not an included angle and other angles are congruent.

Considering triangles ABC and CDE, it can be seen that two angles are congruent and a side of both are congruent. Since the congruent side is not an included angle, then the congruent relations is AAS (Angle-Angle-Side).

The exponential equation that represents the relationship between the air pressure and the elevation above the Earth's surface is

y = 14.7 x 0.827^x

The air pressure at the top of Mount Everest, elevation 29,000 feet is approximately 1.931 psi

To write an exponential equation for the relationship between the air pressure and the elevation above the Earth's surface, we can use the form y = a x b^x,

where y is the air pressure,

x is the elevation,

and a and b are constants.

We can use the data given in the problem to find the values of a and b.

Let y = air pressure (psi)

x = elevation (feet)

We know that at sea level (x = 0), y = 14.7 psi

At Denver, Colorado, elevation 5280 feet, y = 12.15 psi

We can use these two points to find the values of a and b in the equation y = a x b^x

12.15 = 14.7 x b^5280

b = (12.15/14.7)^(1/5280)

b = 0.827

a = 14.7

The exponential equation that represents the relationship between the air pressure and the elevation above the Earth's surface is

y = 14.7 x 0.827^x

b.) To find the air pressure at the top of Mount Everest, elevation 29,000 feet, we can substitute that value for x into the exponential equation.

y = 14.7 x  0.827^29000

y = 1.931 psi

The air pressure at the top of Mount Everest, elevation 29,000 feet is approximately 1.931 psi. It's worth noting that this is a very low air pressure and the human body is not able to survive with such low pressure without proper equipment.

Answer: The cost of both services is equal when h = 2 hours.

Step-by-step explanation: The shared point on the table is when the cost of the two services is equal, i.e. when C1 = C2, where C1 is the cost of Five Seconds of Summer's service and C2 is the cost of Fall Out Boy's service.

To graphically solve the system, we can plot the two equations on the same coordinate plane. The x-axis represents the number of hours and the y-axis represents the cost. The equation for Five Seconds of Summer's service would be y = 5 + 5x and the equation for Fall Out Boy's service would be y = 9 + 3x

We can then find the point of intersection of the two lines, which represents the point at which the cost of the two services is equal. We can label this point as (x, y) and our solution.

To solve the system algebraically using substitution, we can set C1 = C2 and solve for the number of hours (h) in terms of cost.

C1 = 5 + 5h = C2 = 9 + 3h

5 + 5h = 9 + 3h

2h = 4

h = 2

So, the cost of both services is equal when h = 2 hours.

From the above result, it is clear that Fall Out Boy's service is cheaper than Five Seconds of Summer's service. For 2 hours of tutoring, the cost of Fall Out Boy's service is $9 + 3(2) = $15 and the cost of Five Seconds of Summer's service is $5 + 5(2) = $15.

However, there could be scenarios where one service is cheaper than the other depending on the number of hours of tutoring required. For example, if a student requires more than 4 hours of tutoring, Five Seconds of Summer's service would be cheaper. And if a student requires less than 2 hours of tutoring, Fall Out Boy's service would be cheaper.

In conclusion, the best option would depend on the number of hours of tutoring required, and it is best to check both options and compare the cost before making a decision

Answer:

To compare the costs of the two tutoring services, we can set up a system of equations. Let x be the number of hours of tutoring.

Five Seconds of Summer's tutoring service:

y = 5 + 5x (base charge of $5 and $5 per hour)

Fall Out Boy's tutoring service:

y = 9 + 3x (base fee of $9 and $3 per hour)

We can make a table to compare the costs of the two services at different number of hours:

Hours (x) Five Seconds of Summer (y) Fall Out Boy (y)

0                                 5                          9

1                                 10                         12

2                                 15                         15

3                                 20                         18

4                                      25                         21

The shared point in the table is when x = 0, y = 5 for Five Seconds of Summer's tutoring service and y = 9 for Fall Out Boy's tutoring service.

We can graph the two equations to compare the costs:

[Graph would be here if I were able to create one]

From the graph we can see that for any number of hours greater than 0, Five Seconds of Summer's tutoring service is cheaper.

We can also solve the system algebraically using substitution.

The measure of diagonal in a rectangular pool is 13.9 meters. Therefore, option A is the correct answer.

By multiplying the mean of random variable X by two to four, the random variable Y's mean is calculated to be 20. (5). By dividing the X standard deviation (25), by 4, the standard deviation of Y is equal to 102.

The random variable X has a mean of 5 and a standard deviation of 25. A normal distribution's mean serves as its nucleus, and the standard deviation quantifies how much the values deviate from the mean. Y = 2 + 4X is the definition of the random variable Y. By adding 2 to the mean of X (5), we can determine the mean of Y, which equals 20. By dividing the standard deviation of X (25), by 4, we can determine the standard deviation of Y, which yields a standard deviation of 102 for Y. As a result, the standard deviation is 102 and the mean of Y is 20.

Answer: a. The equation using the information as it is given above that can be solved to answer this question is:

distance = speed x time

Let t be the amount of time Krystal spent driving from Houston to Philadelphia.

distance = 50t + 60(46 - 25 - t)

b. To find the distance between Houston and Philadelphia, we can substitute the known values into the equation and solve for t.

distance = 50t + 60(46 - 25 - t)

distance = 50t + 60(21) - 60t

distance = 50t + 1260 - 60t

distance = -10t + 1260

To find the total distance, we can set t = 25

distance = -10(25) + 1260

distance = -250 + 1260

distance = 1010

Therefore, Houston is 1010 miles from Philadelphia, to the nearest mile.
