Answer:
3000 people live in brainesville
Step-by-step explanation:
Population of brainville =2000
Grow rate of population per year =10%
10% of population =2000*10/100=200
Grow rate of 5 year=200*5=1000
After 5 year population of brainville is=2000+1000=3000
Nadia saved 10% of $24.90.
10% x 24.9 = 2.49
answer: $2.49
-4 first we rearrange the question x-2y=8
x-2y=8
-2y=-x+8
y=1/2x-4 (divide by -2 everywhere)
-4 is the y intercept.
The angle between their paths to the nearest degree is 68⁰.
<h3>
Displacement of each boats after 45 minutes</h3>
first displacement, a = 15 km/h x (45/60)
first displacement, a = 11.25 km
second displacement, b = 18 km/h x (45/60)
b = 13.5 km
<h3> Angle between their paths to the nearest degree</h3>
c² = a² + b² - 2ab(cosθ)
2ab(cosθ) = a² + b² - c²
cosθ = (a² + b² - c²)/(2ab)
cosθ = (11.25² + 13.5² - 14²) / (2 x 11.25 x 13.5)
cosθ = 0.371
θ = arc cos(0.371)
θ = 68.22 ⁰
Thus, the angle between their paths to the nearest degree is 68⁰.
