Find the length of the third side of each triangle mark
Sedaia [141]

Answer:

I'm going to use the Pythagoras theorem

1. hypotenus²= base²+height²

h²=80²+18²

h²=6400+324

√h²=√6724

hypotenuse= 82

2. 53²=45²+h²

2809=2025+h²

2809-2025=h²

784=h²

√784=√h²

h=28

3. 40²=b²+24²

1600=b²+576

1600-576=b²

√1024=√b²

b= 32

Barry's final score is 45 which player had the greater final score?
natali 33 [55]

The player with the greater final score is of:

Barry.

<h3>How to obtain which player had the greater final score?</h3>

Barry's final score is given as follows:

45.

Then we have to obtain Lee's score, from the description given in the missing information section.

Lee's scored is obtained as follows:

  • Starts at -350.
  • Answers a 275-point question correctly, hence - 350 + 275 = -75.
  • Answers a 70 - point question correctly, hence -75 + 70 = -5.
  • Answers a 50 - point question incorrectly, hence: -5 - 50 = -55.

Thus Lee's final score is given as follows:

-55.

The classifications of the final scores according to the signals are given as follows:

  • Barry: positive score.
  • Lee: negative score.

A positive score will always be greater than a negative score, hence Barry had the greater final score.

<h3>Missing information</h3>

Lee and Barry play a trivia game in which questions are worth different numbers of points. If a question is answered correctly, a player earns points. If a question is answered incorrectly, the player loses points. Lee currently has -350 points.

a. Before the game ends, Lee answers a 275 -point question correctly, a 70 -point question correctly, and a 50 -polnt question incorrectly. Write and find the value of an expression to find Lee's final score.

b. Barry's final score is 45. Which player had the greater final score?

What is the inverse of the relation? <br> {(-4,1), (-4,3), (0,-8), (8,-9)}
BigorU [14]

The inverse relation would be each of these ordered pairs switched.

{(1, -4), (3, -4), (-8, 0), (-9, 8)}

This is because when you create an inverse equation, all of the inputs become outputs and all of the outputs become inputs. Therefore, the ordered pairs simply switch.
