Answer:
The bar scale is the ruler-like graphic scale and on this picture, it is located in the bottom left corner. The way you measure with it is you take a ruler or a compass and measure the distance between the two points. Then you use the distances on the bar scale and the distance you measured to see the air distance between the two points.
Answer:
Yuki was curious if \triangle ABC△ABCtriangle, A, B, C was congruent to \triangle FED△FEDtriangle, F, E, D, so she tried to map one triangle onto the other using transformations: Yuki concluded: "It's not possible to map \triangle ABC△ABCtriangle, A, B, C onto \triangle FED△FEDtriangle, F, E, D using a sequence of rigid transformations, so the triangles are not congruent." What error did Yuki make in her conclusion?

Answer: The correct options are:
<em>exerts more pressure as it increases
</em>
<em>measures how tightly molecules are packed
</em>
<em>equals mass divided by volume</em>
Explanation:
Air density can be described as mass per unit of volume of the volume of air.
As the altitude increases, the air density tens to decrease. Hence, option A is not correct.
The density of the air determined how many atoms of air can occur in a particular volume, In other words, it determines how tightly or loosely atoms of air are packed in a particular volume.
Hence, when the air density will increase, the molecules will be more tightly packed and the pressure will be more.
