Answer:

The information we need is that the angle between the sides (that is, angle TVU for triangle TVU and angle WVX for triangle WVX) need to be equal.

These angles are vertically opposite angles, because they are formed by two lines crossing, so these angles are equal.

Step-by-step explanation:

The SAS Congruence Theorem says that if two triangles have 2 equal sides and the angle between these sides are also equal, the triangles are congruent.

In this question, we know that the sides UV and VW are congruent, as V is the midpoint of UW. We also know that TV = VX, so now we have two equal sides for each triangle.

The information we need is that the angle between the sides (that is, angle TVU for triangle TVU and angle WVX for triangle WVX) need to be equal.

These angles are vertically opposite angles, because they are formed by two lines crossing, so these angles are equal.

Now we can conclude that the triangles are congruent.

How many different 7-digit telephone numbers are possible if the first digit cannot be 0, but the last two digits must be 0?

solniwko [45]

The first digit can only range from 1-9, resulting in 9 possible options. The next four digits can range from 0-9, resulting in 10 options for each. Since the last two digits remain the same, they do not affect the sample size. Using the fundamental counting principle, we can find the amount of telephone numbers possible in the following equation.
$9 \times 10 \times 10 \times 10 \times 10 \times 1 \times 1 \\ 90000$

In order to be invited to tutoring or extension activities, a student's performance must be at least 20 points higher or lower t

marissa [1.9K]

Answer:

The inequality that represents p are p $\geq$ 125 or p $\leq$ 85.

Step-by-step explanation:

We are given that in order to be invited to tutoring or extension activities, a student's performance must be at least 20 points higher or lower than an average score. The average score is 105.

Let p = the scores for students who are eligible for tutoring or extension activities.

<u>The first condition</u> states that a student's performance must be at least 20 points higher than an average score, that means;

p $\geq$ (105 + 20)

p $\geq$ 125

Similarly, <u>the second condition</u> states that a student's performance must be at least 20 points lower than an average score, that means;

p $\leq$ (105 - 20)

p $\leq$ 85

So, the inequality that represents p are p $\geq$ 125 or p $\leq$ 85.
