Mariana is taking a multiple choice test with a total of 80 points available. Each question is worth exactly 4 points. What woul

Sladkaya [172]

Mariana's score if got right if she got 5 wrong is 60 points.

Mariana's score if got right if she got xx wrong is 80 - 4xx.

<h3>What is Mariana's score?</h3>

The first step is to determine the number of questions that Mariana got right. In order to get the number of questions that she got right, subtract the total number of number of questions from the questions that he got wrong.

Questions that Mariana got right = total number of questions - questions he got wrong

Total number of questions = total number of points / point of each question

Total number of questions = 80 / 4

Total number of questions = 20

Questions that Mariana got right if he got 5 wrong = 20 - 5 = 15

Mariana's score = questions she got right x number of points per question

Mariana's score = 15 x 4 = 60 points

Questions that Mariana got right if he got x wrong = 20 - xx

Mariana's score = (20 - xx) x 4

Mariana's score = 80 - 4xx

Is this angle side angle, angle angle side, or not congruent.

KatRina [158]

<h3>Answer: C) Not congruent</h3>

We have 2 pairs of congruent angles, so we can prove the triangles are similar triangles (using the AA similarity theorem). But we don't have enough information to prove them to be congruent. We would need at least one pair of sides to be congruent so we could use either AAS or ASA.

For instance, if we knew that AT = AP, then we would use AAS. If we knew that HT = MP, then we would use ASA instead. However, we don't have either bit of information like this. The triangles may or may not be congruent. We simply don't have enough information to say either way. We can't definitively say they are congruent, so we just lean toward "not congruent".
