This Question: 1 pt 10 of 10 (8 complete) Th One day a store sold 30 sweatshirts. White ones cost $11.95 and yellow ones cost $1
ohaa [14]
W + y = 30......w = 30 - y
11.95w + 12.50y = 364.55

11.95(30 - y) + 12.50y = 364.55
358.50 - 11.95y + 12.50y = 364.55
-11.95y + 12.50y = 364.55 - 358.50
0.55y = 6.05
y = 6.05 / 0.55
y = 11 <=== there were 11 yellow sweatshirts sold

w + y = 30
w + 11 = 30
w = 30 - 11
w = 19 <=== there were 19 white sweatshirts sold

Which of the following is not a Pythagorean triple?
Ierofanga [76]

Answer:

  (7, 24, 26)

Step-by-step explanation:

A Pythagorean triple must have an odd number of even numbers. The triple (7, 24, 26) is not a Pythagorean triple.

_____

<em>Additional comment</em>

For an odd integer n, a triple can be formed as ...

  (n, (n²-1)/2, (n²+1)/2)

That is, the following will be Pythagorean triples.

  • (3, 4, 5)
  • (5, 12, 13)
  • (7, 24, 25)
  • (9, 40, 41)
  • (11, 60, 61)

Another series involves even numbers and numbers separated by 2:

  (2n, n²-1, n²+1)

  • (8, 15, 17)
  • (12, 35, 37)
  • (16, 63, 65)

In this list, if n is not a multiple of 2, the triple will be a multiple of one from the odd-number series.

It is a good idea to remember a few of these, as they tend to show up in Algebra, Geometry, and Trigonometry problems.
