The correct answer, rounded to the nearest km², is 2694.
Explanation:
This can be represented using an exponential equation of the form
y = a(1+r)ˣ, where y is the total amount, a is the initial population, r is the rate of increase or decrease written as a decimal number, and x is the amount of time.
In our problem, a = 4200, r = -8.5% = -8.5/100 = -0.085, and x is 5:
y = 4200(1+-0.085)⁵ = 4200(0.915)⁵ = 2693.73 ≈ 2694.
Answer:
C
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(7x - 40) is an exterior angle of the triangle, then
7x - 40 = 3x + 3x - 20
7x - 40 = 6x - 20 ( subtract 6x from both sides )
x - 40 = - 20 ( add 40 to both sides )
x = 20 → C
Answer: or x ÷ 5
