Answer:
Expected Family Contribution
Explanation:
A P E X
C
5x < 30
Divide each side by 5 to find x
x < 6
The number line needs to show the x represents any number less than 6 (3, 5.5, -1, etc)
C is correct because there is an open circle around 6, and then an arrow pointing towards numbers smaller than 6.
If x is less then or equal to six, you draw a filled in circle around six to show that x can be 6.
Because x is less than 6 and not equal to 6, you draw an open circle to represent x can get very close to 6 (ex. 5.9, 5.999) but cannot equal 6.
The line has to be pointing leftwards because the numbers are less then six in that direction. X can be any number smaller than 6, which is how by the leftward arrow

Answer:
8.0 mi
Explanation:
Let's call your triangle ABC as in the diagram. We can use the SAS property of triangles and the Law of Sines.
1. Determine m∠B
m∠ B + 72° = 180°
m∠B = 108°
2. Determine b
By the Law of Sines,
b/sinB = c/sinC
b = c(sinB/sinC)
= 3 × (sin108°/sin17°)
= 3 × 0.951/0.292
= 9.76 mi
3. Calculate the area of ∆ABC
Area = ½ bc sinA = ½ × 9.76 × 3sin55° = ½ × 9.76 × 3 × 0.819 = 12.0 mi²
4. Calculate h
Area = ½ × base × height
12.0 mi² = ½ × 3 mi × h
h = 2 × 12.0 mi/3= 8.0 mi
The altitude of the plane is 8.0 mi.
