Answer:
Step-by-step explanation
51.4% of the total population is 126 million
let x be the total population
turn ur percent to a decimal
0.514x = 126,000,000
x = 126 / 0.514
x = 245,136,186.77 <==
First way of finding area is the usual formula.
Area of a rectangle = Length × Breadth
= 3x × x
= 3x^2
Second way of finding area of the bigger rectangle is adding both the rectangles' areas and subtracting by the area of the smaller rectangle.
Area of smaller rectangle:
Length × Breadth = 2 × x
= 2x
Area of bigger rectangle + Area of smaller rectangle = 3x^2 + 2x
Subtracting it by the area of the smaller rectangle:
3x^2 + 2x - 2x = 3x^2
Answer:
1. V(12) = $ 1200
2. V(20) = $ 4800
Step-by-step explanation:
The following data were obtained from the question:
V(t) = 150 × 2ᵗ/⁴
V(12) =?
V(20) =?
1. Determination of V(12)
Time (t) = 12 years
V(12) =?
V(t) = 150 × 2ᵗ/⁴
V(12) = 150 × 2¹²/⁴
V(12) = 150 × 2³
V(12) = 150 × 8
V(12) = $ 1200
2. Determination of V(20)
Time (t) = 20 years
V(20) =?
V(t) = 150 × 2ᵗ/⁴
V(20) = 150 × 2²⁰/⁴
V(20) = 150 × 2⁵
V(20) = 150 × 32
V(20) = $ 4800
