The answer to this would be 14 units hope it helps :)
8 because only the green marbles got added
Answer:
31.46 km/hr to the nearest 100th
Step-by-step explanation:
10:55 to 11:00 is 5 min
11:00 to 12:00 is 60 min
12:00 to 12:38 is 38 min
That's 5 + 60 + 38 = 103 min = 103/60 hr. = t
d = rt
54 = 103/60(r)
r = 54(60)/103 =31.46 km/hr to the nearest 100th
Assuming the room is a rectangle...
The area of a rectangle = its length × its width.
The amount of carpet we need to cover our rectangular room = 8.5 ft × 7.5 ft
Use decimal long multiplication or otherwise to get 63.75 ft².
Radius = Diameter ÷ 2
Radius = 10 ÷ 2 = 5
.
Volume = πr²h
Volume = π(5)² (20) = 500π cm³
.
Answer: 500π cm³
