Answer:
9 Signs
Step-by-step explanation:
The hiking trail is 4 kilometer long.
Signs are placed at the beginning and at the end of the trail.
4km = 4000m
We can solve this using simple arithmetic progression.
- The first term,a= 0
- The common difference,d= 500.
- The last term,l= 4000.
Therefore:
Last term, l=a+(n-1)d
4000=0+500(n-1)
4000=500n-500
4000+500=500n
4500=500n
Divide both sides by 500
n=9
Therefore, there are a total of 9 signs on the entire trail.

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
40° + (y + 30)° + y° = 180°
<u>Step 2: Solve for </u><em><u>y</u></em>
- Combine like terms: 2y° + 70° = 180°
- Isolate <em>y</em> term: 2y° = 110°
- Isolate <em>y</em>: y° = 55°
