What is the condition for 3 lengths to represent a triangle?In a triangle, the sum of the lengths of the two smaller sides of the triangle has to be greater than the length of the greater side of the triangle.
For the first letter, we have two sides, hence there are many possible values for the third side x, as long as 2.5 + x > 8, for x < 8 or x < 10.5, for x > 8, hence the first letter of the code is of B.
For the second letter, 4 + 7 < 19, hence no triangle can be formed with these dimensions and the letter is of B.
For the third letter, 2 + 4 > 5, hence one unique triangle can be formed with all the dimensions given and the letter is of B.
For the fourth letter, 6 + 8 > 12, hence one unique triangle can be formed with all the dimensions given and the letter is of A.
For the fifth letter, we have two sides, hence there are many possible values for the third side x, as long as 1 + x > 2.4, for x < 2.4 or x < 3.4, for x > 2.4, hence the letter is of C.
For the sixth letter, 5 + 9 > 13, hence one unique triangle can be formed with all the dimensions given and the letter is of C.

3)a) The angles are congruent by alternate interior angles postulate.
b) The angles are congruent by linear pairs postulate.
c) The angles are congruent by corresponding angles postulate.
How to find corresponding angles?When two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.
1) From definition of corresponding angles, line m is parallel to line n and as such, we can say that;
2x + 12 = 38
2x = 38 - 12
2x = 26
x = 13

which distribution is appropriate when counting the number of successes in n trials if the probability of success p remains constant from trial to trial? multiple choice question.
When counting the number of successes in n trials, the (D) binomial distribution should be used if the success probability, p, stays constant from trial to trial.
What is binomial distribution?When each trial has the same probability of achieving a given value, the number of trials or observations is summarized using the binomial distribution. The probability of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution. When counting the number of successes in n trials, the binomial distribution should be used if the success probability p stays constant.For the trials we are looking at, the probability of receiving success in a binomial distribution must stay constant. Since there are only two possible outcomes when tossing a coin, for instance, the probability of flipping a coin is 12 or 0.5 for each trial we conduct.As it is given in the descrip[tion itself that the probability of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution.
When counting the number of successes in n trials, the binomial distribution should be used if the success probability p stays constant.Therefore, when counting the number of successes in n trials, the (D) binomial distribution should be used if the success probability, p, stays constant from trial to trial.

The distinct lines ABC and deer in the same place tell how Line A. And line B. related to each other justify your answer a ll b,b ll c,c | d
Line A is perpendicular to D because a is parallel to c and c is perpendicular to d.
How are parallel straight lines related?Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope. Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.
WE have been given that a ll b,b ll c,c is perpendicular to d.
Here the line a is parallel to b and b is parallel to c so a must be parallel to c.
As we know that c is perpendicular to d since, a is parallel to c.
Therefore, Line A is perpendicular to D because a is parallel to c and c is perpendicular to d.

The inequalities that model each situation are given as follows:
a. w ≤ 20, meaning that vehicles with two axles can weight at most 20 tons.
b. w ≤ 30, meaning that vehicles with three axles can weight at most 30 tons.
c. w ≤ 40, meaning that vehicles with four axles can weight at most 40 tons.
Which inequalities models each situation?In each inequality, the plotted numbers are the numbers to the left, with a closed circle, hence:
The numbers to the left means that the numbers less than the value are part of the solution of the inequality.The closed circle means that the bound is a solution to the inequality.In item a, we have that for vehicles with 2 axles, the upper weight limit is of 20 tons, hence the inequality is:
w ≤ 20.
In item b, we have that for vehicles with 3 axles, the upper weight limit is of 30 tons, hence the inequality is:
w ≤ 30.

A train leaves city A at 0800 h and travels at a uniform speed of 60 kmh¹ towards city B. Another train leaves city B at the same instance and travels at a uniform speed of 40 kmh¹ towards city A. If the distance between the two cities A and B is 100 km, calculate the time at which the two trains pass each other.
The 100 km difference between the two cities takes two trains to pass each other in 5 hours.
What do time, distance, and speed mean?The relationship between speed, distance, and time is described using the formula of speed, distance and time.
That is speed = distance/time.
What is relative speed?The velocity of an object in relation to another observer is referred to as the relative speed.
Given:
A train departs from city A and moves toward city B at a constant speed of 60 km/h and time taken is 8 hours.
At the same time, a second train departs city B and heads toward city A at a constant speed of 40 km/h.
The relative speed of first train with respect to the second train = 60-40
= 20 km/h
It is given that the two cities A and B are located 100 kilometers apart from one another.
So, distance between both cities = 100 km
By using the speed formula,
Speed = Distance/Time
Time = Distance/Speed
Time = 100/20
∴ Time = 5 hours
Consequently, it takes 5 hours for the two trains to pass one another with 100 km distance between two cities.
