Answer:

right

Step-by-step explanation:

Vertical angles are congruent.

A pair of right angles is the only kind of pair of congruent angles that is supplementary.

An acute angle will be supplementary to an obtuse angle, and vice versa.

A straight angle measures 180°, so is only supplementary to one that measures 0°.

For the conversion of 0.0003140 kilograms to ounces, the conversion factors are 103 grams per kilogram, 1 pound per 453.6 grams

Ksenya-84 [330]

The correctly expressed answer is 1.108 × 10⁻² ounces.

Explanation

The conversion factors are 10³ grams per kilogram, 1 pound per 453.6 grams and 16 ounces per pound.

So, 0.0003140 kilograms = $(0.0003140*10^3)grams = 0.3140 grams$

Now, 1 pound = 453.6 grams

⇒ 1 gram = $(\frac{1}{453.6}) pound$

So, 0.3140 grams = $(0.3140* \frac{1}{453.6})pound$

Now,

$(0.3140*\frac{1}{453.6})pound\\ \\=(0.3140*\frac{1}{453.6}*16 )ounces\\ \\= 0.01108ounces\\ \\= 1.108*10^-^2 ounces$

So, 0.0003140 kilograms = 1.108 × 10⁻² ounces.
