The sum of all odd numbers form 1 to 99 is_____.

1 answer:

6 0

The sum of all the odd numbers from 1 to 99 is easy to explain. Take the first and last numbers, 1 and 99. They add up to 100. Then take the next two numbers, 2 and 98. They also add up to 100. If you keep doing this, you will get 25 numbers that can be multiplied by 100. So the answer is 2,500.

There are two water tanks, Tank #1 fills into Tank #2.

cricket20 [7]

Answer:

35 minutes

Step-by-step explanation:

The total amount of water is 200 +60 = 260 gallons. The two tanks will have equal amounts when each has half that, or 130 gallons.

If the volume in tank 2 is increasing at 2 gallons per minute, it will increase by 70 gallons from 60 gallons to 130 gallons in 70/2 = 35 minutes.
