While mining, Keith found a large metal bar that weighed 42 ounces. Keith was also able to determine that the bar had 30 ounces

Usimov [2.4K]

Divide the silver present in the bar by the total weight of the bar to find the percentage of silver in the bar.

$30 / 42 = 0.7142$

Multiply this decimal by 100 for the percentage.

$.7142 * 100 = 71.42$

Rounded to the nearest tenth, 71.4% of the weight of the bar is silver.

Answer:

(-∞, -12), (2, ∞)

(-∞, -12) U (2, ∞)

Step-by-step explanation:

|3x + 15| > 21, |3x + 15| < -21

3x + 15 > 21, 3x + 15 < - 21

-15 -15 -15 -15

Which expression is a polynomial

patriot [66]

Answer:

$4x^3-2x^2+5x-6+\frac{1}{x}$ is a polynomial

Step-by-step explanation:

a polynomial is a set of numbers with multiple terms that are not simplify able

$9x^7y^{-3} z$ is not a polynomial because its actually one term, there is no addition/subtraction of different terms.

-13 is a single number, so not a polynomial

13x^-2 is also a single number, not a polynomial
