Organize the lengths below from shortest to longest.

28 dm ,629,000 mm ,1.2 km, 30,277 cm

To answer this, all values should be converted in the same unit just like in km

28 dm = 0.0028 km

629,000 mm = 0.629 km

1.2 km

30,277 cm = 0.30277 km

So the order is 28 dm, 30,277 cm , 629,000 mm and 1.2 km

b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did t

saveliy_v [14]

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.

pychu [463]

Answer:

Here's what I get

Explanation:

Per the above explanation, pH means "power of hydrogen ions."

The concentration of hydrogen ions is a measure of the acidity of a solution. A higher concentration represents a more acidic solution.

The definition of pH is

pH = -log[H⁺]

Thus, pH is a measure of the hydrogen ion concentration.

The more negative the pH, the greater the Potenz of hydrogen ions.

Explanation:

Epithelial tissues is responsible for the protection of the skin, absorption of nutrients during digestion and secretion of waste materials. These tissues form covering to all body surfaces. They also perform a variety of other functions such as excretion of waste substances, filtration of air from dirt and particles and clean the air that is inhaled, diffusion, and sensory reception.
