A) A = 20,000 [Principle] * (0.05 [Interest] * 4 [Number of years]) = $4,000 interest
b) A = 20,000 [Principle] * (0.05 [Interest] * 2 [Number of years]) = $2,000 interest
Step-by-step explanation:
(A²)⁴ = A⁸
(D³)² = D⁶
(5⁴)² = 5⁸
One inch equals 25 miles
Two inches equals fifty miles
Three inches equals seventy five miles
Four inches equals one hundred miles
.1 inches equals 2.5 miles
.4 inches equals 10 miles
Seventy five miles plus ten miles equals eighty five miles.
Split the surface area into geometric shapes as shown in the figure below.
Top part
The area of one triangle is
A₁ = (1/2)*(10 cm)*(4 cm) = 20 cm²
There are 3 of these triangles.
Vertical sides..
The area of one vertical side is
A₂ = (10 cm)*(6 cm) = 60 cm²
There 3 of them.
Bottom part
The triangle is equilateral with each side = 10 cm, and each angle = 60 deg.
The area is (from the Law of Sines) equal to
A₃ = (1/2)(10 cm)*(10 cm)*sin(60) = 43.3 cm²
The total surface area is
3A₁ + 3A₂ + A₃
= 3*20 + 3*60 + 4.3
= 283.3 cm²
Answer: The surface area is 283.3 cm²
