In one year, $ 9,000 with a profit of 7.75%, is $ 697.5
697.5 × 18 = 12555
After 18 years old, it is $ 15,222
<span>6 km × 1 hour/(b-4 km) = 12 km × (1 hour/(b+4 km)
6/(b-4) hours = 12/(b+4) hours
6(b+4) = 12(b-4)
6b + 24 = 12b - 48
72 = 6b
b = 12
The boat's speed in still water is 12 km/hour.</span>
Answer:
67 ½ units³ or 135/2 units³
Step-by-step explanation:
Volume = Base area × height
In case:
width is 6 the height is 4 1/2 and the length is 2 1/2
2 ½ = 5/2
4 ½ = 9/2
Volume = (6 × 5/2) × 9/2
= 15 × 9/2
= 135/2
= 67 ½ units³
