Because the arrow is pointing to the left, the answer to the solution set needs to be less than the the number the dot is on.
A solid dot on a number means that that number is included in the solution set.
In the picture the solid dot is on 4.5, so the solution set needs to be equal to or less than 4.5.
The answer is:
{x | x ≤ 4.5}
Answer:
The firstgear needs to make five revolutions in order for the marks to line up again.
Step-by-step explanation:
The midpoint between -4 and 8 is answer B) 2
The value 0.92 indicates the relative density of the ice.
Data;
- Density = 0.92g/ml
- Specific gravity = 0.92
<h3>Specific Gravity</h3>
Specific gravity of a substance is defined as the relative density of substance. This can be further said to be the ratio between the density of a substance to the density of the reference substance.
mathematically;

The value 0.92 indicates the relative density of the ice.
