The sets of numbers 6, 8, 10 and 5, 12, 13 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain or show why they are Pythagorean triples. Be sure to show your work for each set of triples!

Answers

Answer:

We know that the Pythagorean Theorem is a² + b² = c². First lets start with 6, 8, and 10. There is a simple way to know that these are Pythagorean triples. They make up what is called a 3-4-5 triangle. 3 x 2 is 6, 4 x 2 is 8, and 5 x 2 is 10. Next 5, 12, and 13 are Pythagorean triplets because 5² + 12² = 13². Because both of these form right triangles, we know that they are Pythagorean triplets.

4 shirts for $14. How many shirts can you purchase for $30?

Plz show your work

Answers

Answer:

2 shirts

Step-by-step explain

14 times 2 is 28 and you cant go over the price so yes 2

Well the person above must have read the question wrong because the answer would actually be 8 because if you can buy 4 shirts for 14 dollars then if you doubled 14 it would just be under 30 with 28 dollars and yes you can’t go over so the most you could buy is 8

Answers

Answer: so it goes -12-->4-->-5--->-7--->-1-->-9-->-6-->6-->45--->-36 And then your there! make sure you look at which numbers are positive and negative in my answer. your welcome :)

Step-by-step explanation:

Note that:

If you multiply 2 negative numbers, your answer will be positive.

If you multiply 1 negative & 1 positive number, your answer will be negative.

If you multiply 2 positive numbers, your answer will be positive.

Start:

-4 x 3 = -12

-2 x -2 = 4

25/(-5) = -5

(-49)/7 = -7

-5 x (1/5) = -1

(-3)(-3)(-1) = (-3 * -3)(-1) = (9)(-1) = -9

(3/4) x -8 = (3 * -8)/4 = 3 * -2 = -6

-18/-3 = 6

-9 x - 5 = 45

12/(-1/3) = 12 * -3 = -36

Finish.

the code will be the sum of all your answers:

-12 + 4 - 5 - 7 - 1 - 9 - 6 + 6 + 45 - 36 = -21

-21 is your code.

Solve the inequality c – 5 ≥ 0.5 and graph the solutions.

Answers

the answer is c ≥ 5.5

Answer:

c ≥ 5.5

Step-by-step explanatation:

c - 5 ≥ 0.5

*Add 5 to the left and the right of the inequality symbol*

Which leaves you with, c ≥ 5.5

In this case, the 'c' is unknown when graphing because you don't know if it can be called x or y. So, you cannot plot this variable.
