Step-by-step explanation:
Answer:
50g/cm is equal to 5 kg/m
Step-by-step explanation:
as we know that:
10g/cm = 1 kg/m
so,
50g/cm = 5kg/m
The distance to the store is
.. (0.3 h)*(10 mi/h) = 3 mi
The time home is
.. (3 mi)/(30 mi/h) = 0.1 h
The average speed is the total distance divided by the total time
.. speed = (3 mi +3 mi)/(0.3 h +0.1 h) = (6 mi)/(0.4 h) = 15 mi/h
Ishaan's average speed was 15 mi/h.
The expression for the balance (b) in terms of the number of years (t) can be written as
... b = 2000·2^(t/19) . . . . . . the amount grows exponentially, and is is doubled when t=19
Then for t=5, the balance is
... b = 2000·2^(5/19) ≈ 2400
The best choice is ...
... A. $2400
