7) Rectangular pyramid:
Length = 8m ; width = 4.6m ; Volume = 88m³
Volume of a rectangular pyramid = (Length * Width * Height)/3
88m³ = (8m * 4.6m * height)/3
88m³ * 3 = 36.8m² * height
264m³ = 36.8m² * height
264m³ / 36.8m² = height
7.2 m = height
8) Cone:
r = 5 in ; volume = 487 in³
Volume of a cone = π r² h/3
487 in³ = 3.14 * (5in)² * h/3
487 in³ * 3 = 3.14 * 25in² * h
1,461 in³ = 78.5 in² * h
1,461 in³ / 78.5 in² = height
18.6 in = height
Answer:
$4.21
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 4.9 × 14/100
Discount = 4.9 x 0.14
You save = $0.69
Final Price = Original Price - Discount
Final Price = 4.9 - 0.686
Final Price = $4.21
D. 5x = 45 because you are trying to find x, the number of tickets that must be sold to earn $45.
Answer:
