SAT

Answer: False

Explanation: When a human takes part in an experiment, this human is called a "research participant" or a "human subject".

While is true that you may think in these humans as "variables" of some kind, this is not really the case because there is a whole different system, where you just can't do a change in your human subject as you want, so these people are not real "variables" in the experiment.

Then, the statement is false.

Which of the following will be the ratio of the perimeter of the blue triangle to the red triangle.
Kazeer [188]

The ratio (red to blue) of the perimeters of the similar triangles is 12:7

Assuming that the similar triangles are equilateral triangles, then all their sides will be equal.

Perimeter of a triangle = s1 + s2 + s3

For the red triangle;

Perimeter of the red triangle = 12 + 12 + 12

Perimeter of the red triangle = 36

For the blue triangle:

Perimeter of the blue triangle = 7 + 7 + 7

Perimeter of the blue triangle = 21

Taking the ratio of their perimeters;

Ratio of red to blue = 36:21 = 12:7

Hence the ratio (red to blue) of the perimeters of the similar triangles is 12:7

The suns photosphere
Blababa [14]

Answer:

The photosphere is the visible surface of the Sun that we are most familiar with. Since the Sun is a ball of gas, this is not a solid surface but is actually a layer about 100 km thick (very, very, thin compared to the 700,000 km radius of the Sun).
