Answer:
x = 6
Step-by-step explanation:
Using the Laws of Cosine, we obtain
, which c approximately equals 153.44. So Line AB ≈ 153.44 meters.
It is neither 25^2 which equals 625 once you square root it .
Answer:
300 adults and 450 students
Step-by-step explanation:
We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 750 people attended, then s+a=750.
We also know they made $1200 and adult tickets cost $2.50 and student tickets cost $1. We can write 1s+2.5a=1200.
We will solve by substituting one equation into the other. We start by solving the first equation for c. s+a=750 becomes s=750-a.
Now we substitute s=750-a into 1s+2.5a=1200. Simplify and isolate the variable a.
- 1(750-a)+2.5a=1200
- 750-a+2.5a=1200
- 750+1.5a=1200
- 750-750+1.5a=1200-750
- 1.5a=450
- a=300
This means that 300 adults attended and 450 students attended since 300+450=750.
