13/52 is the ratio of hearts to all cards
That reduces to a 1/4 ratio
or a 25% chance of drawing a heart
The digit '1', the first copy of '1', is in the ten thousands place. To the right of this digit is 3. Since 3 is not 5 or larger, we simply change everything after the '1' to zeros
So we go from 413,125 to 410,000
The final answer is 410,000
Step-by-step explanation:
10,000x5=50,000
100x4=400
3x1=3
Total = 50,403

- <em>It takes</em><u> 2.5 minutes </u><em>to fill the tank.</em>
Explanation:
The net speed or net rate for filling the 10-liters tank is equal to the speed the tap is filling less the speed the water is leaking through the hole located at the bottom of the tank:
- Net rate = rate of filling - rate of leaking
- Net rate = 5 liters/minute - 1 liter/minute
- Net rate = 4 liters/minute
Thus, consiedering the tank is empty at the beginning, the time is:
- Time = Volume of the tank / net rate of filling
- Time = 10 liters / (4liters/minute)
- Time = 2.5 minutes ← answer
