Answer:
a. 277.3 m²
b. $307.86
Step-by-step explanation:
a. Area of the wall to be painted = area of rectangle - area of triangle
= L × W + ½×a×b×sin θ
L = 17 m
W = 14 m
a = 8.7 m
b = 9.5 m
θ = 72°
Plug in the values into the equation
Area of the wall = (17×14) + (½*8.7×9.5×sin 72)
Area of the wall = 238 + 39.3024105
Area of the wall to paint ≈ 277.3 m²
b. 20 liters of paint of 1 container cost $21.99
If 1 liter of paint covers 1m², therefore,
277.3 m² will need = 277.3 × 1 = 277.3 liters of paint.
20 liters = 1 container of paint
277.3 liters = 277.3/20 = 13.865 ≈ 14 containers
1 container = $21.99
14 containers = 21.99 × 14 = $307.86
Answer:
The correct to the question about is simply C. A is ruled out because it doesn't represent refections
Answer: Dao will pay $ 15,219.2
Step-by-step explanation:
Hi, to answer this question we have to multiply the price of the automobile by the percentage discount in decimal form (divided 100)
18,560 (18/100) = 18,560 (0.18) = $ 3,340.8 (discount amount)
Finally, we have to subtract the discount amount to the automobile's price:
18,560- 3,340.8 =$ 15,219.2
Dao will pay $ 15,219.2.
