Answer:
12,000,000 boxes
Explanation:
the volume of the room can be found by using the equation for volume of a rectangular box:V=LxWxH
where:
L=2m
W=3m
H=4m
(it doesn't really matter which is which since it is multiplication)
when we multiply our values (2m*3m*4m) we get 24cubic meters
now we need to convert cubic meters to cubic centimeters
each cubic meter is 1,000,000 cubic centimeter we multiply 24 by 1,000,000 and we get: 24,000,000 cubic centimeters (cc)
dividing 24,000,000 by 2 (since each box is 2cc) we get 12,000,000
so, we know we can fit 12,000,000, 2 cubic centimeter boxes in this room
The answer is D because i'm in the same studies right now.
Answer:
A.) Time = 0.625 hrs = 37.5 minutes
B.) Speed required = 133.33km/hr
Explanation:
Given the following :
Total race distance = 100km
Total time required = 1 hour = 60 minutes
Average speed after traveling 50km = 80km/hr
80km/hr : This means it will take one hour to cover a distance of 80km
Therefore, time taken to cove first 50km at that average speed equals :
1 hour = 80 km
t hours = 50km
80t = 50
t = 50/80
t = 5/8 hours
t = 0.625hours
t = 0.625 * 60 = 37.5minutes
B)
Average speed required to complete the race in 1 hour = 100km/hr
Time used to complete first 50km = 0.625 hour
Time remaining: (1 - 0.625) hour = 0.375
Speed required = Distance left / time left
Speed required = 50 / 0.375
Speed required = 133.33km/hr
I think it is D
Hope my answer help you?
The correct answer would be to express large and small numbers.
