h = V ÷ l w = 819 ÷ (10 × 9) = 9.1m
Have a good day
Answer:
Step-by-step explanation:
1. We aren't worried about the area of the base, so the area is the area of the 4 triangles. Each triangle has an area of half the base times the height.
A = 4 (½ bh)
A = 2 bh
Given b = 6 and h (the height of the triangle, not the pyramid) = 5:
A = 2 (6) (5)
A = 60 ft²
2. This time, we want to include the area of the rectangular base, so:
A = b₁b₂ + 2 (½ b₁h₁) + 2 (½ b₂h₂)
A = b₁b₂ + b₁h₁ + b₂h₂
Given b₁ = 78 m, b₂ = 50 m, h₁ = 52 m, and h₂ = 60 m:
A = (78) (50) + (78) (52) + (50) (60)
A = 10,956 m²
Answer:
y = 100,000 + 3500x
$142,000
Step-by-step explanation:
a. The fixed cost is 100,000 while appreciation is 3, 500/year.
Now after x years, total appreciation equals 3,500 × x = 3500x
The total amount in dollars is thus :
y = 100,000 + 3500x.
b. The value of the house in 12 years.
Since y = 100,000 + 3500x, here, y = ? and x = 12.
y = 100,000 + 3500(12) = 100,000 + 42,000 = $142,000
