Answer:

B

the measure of angle A: 18.6°

measure of angle B: 55.8°

measure of angle C: 105.6°

Step-by-step explanation:

6x - 6 + 3x + x = 180

10x - 6 = 180

10x (- 6 + 6) = 180 + 6

10x = 186

10x/10 = 186/10

x = 18.6

18.6 + 3(18.6) + [6(18.6) - 6] = 180

18.6 + 55.8 + 105.6 = 180

180 = 180

Write this statement in your own words: ∃x ∈ ℕ, y ∈ ℤ|x² = y² Rewrite this using the appropriate mathematical notation: Even num
Serga [27]

Answer:

See below.

Step-by-step explanation:

1)

So we have:

\exists x\in\mathbb{N},y\in\mathbb{Z}|x^2=y^2

This can be interpreted as:

"There exists a natural number <em>x</em> and an integer <em>y</em> such that x² is equal to y²."

2)

So we want even numbers are in the set of integers.

\{2n:n\in\mathbb{Z}\}\in\mathbb{Z}

This is interpreted as:

"The set of even numbers (2n such that n is an integer) is in the set of integers"

help please! by what fraction would you multiply 8 1/2 so that the proudct is about 5 explain your reasiong
blsea [12.9K]

Answer:

  5/8 or 5/9

Step-by-step explanation:

The fraction will be exactly ...

  5/(8 1/2) = 10/17   ⇒   (8 1/2)×(10/17) = 5

__

The fraction will be approximately ...

  5/8 or 5/9

The denominator will be a number that makes (8 1/2)/(denominator) ≈ 1. For that denominator, the numerator will be 5, so that we have ...

  (8 1/2) × (5/denominator) ≈ 5

  (8 1/2)/(denominator) ≈ 1 .  . . . . . . . divide by 5

If we want the denominator to be an integer, we could choose either 8 or 9. If we choose 8, the result will be slightly more than 5; if we choose 9, the result will be slightly less.

  (8 1/2) × (5/8) = 5.3125 ≈ 5

  (8 1/2) × (5/9) = 4.722... ≈ 5

Either 5/8 or 5/9 will give a product of about 5.
