<u>Answer:</u>

The property of specific gravity is used to separate oil from water in the process of skimming.

<u>Explanation:</u>

  • The specific gravity values of oil and water are different. This allows the oil to adhere better to the skimmer and leave the water behind.
  • Oil bonds better to surfaces that offer friction. As the frictional index of water is negligible, oil floats on the water without mixing up with it, making it easy for the skimmer to skim the oil out of water.

one angle of a triangle measures 125 degrees the other two angles are in a ratio of 4:7. what are the measures of the two angles
Ilya [14]
Angles in a triangle add up to 180 degrees.
180 - 125 = 55
Add the ratios 4+7 = 11
Divide the left over angels by the ratio: 55/11 = 5
Now multiply 5 by each side of the ratio:
4:7
4*5 = 20
7*5 = 35

So the 2 angles are 20 and 35 degrees.

To check, you can add up all the angels : 20 + 35 + 125 = 180
So we know 20 and 35 is correct because it adds up to 180 degrees :)

notsponge [240]

The correct answer is South America.

Explanation

The graph shows the change in forest cover across various regions such as Eastern and Southern Africa, Northern Africa, Western and Central Africa, East Asia, South and Southeast Asia, Western and Central Asia, Europe, Caribbean, Central America, North America, Oceania and South America of the world between 1990 and 2010 (divided into four groups 1990, 2000, 2005 and 2010). According to the graph the region with less change in forest cover is North America because through those years, there were close to 700.000 Ha; the region with the most increase of forest cover is East Asia because in 1990 there were close to 200.000 Ha and in 2010 there were close to 270.000 Ha, and the region with the most decrease of forest cover is South America because in 1990 there were close to 930.000 Ha and in 2010 there were close to 850.000 Ha. According to the above, the correct answer is South America.
