There are two payment types that will help you stick to your budget.

1. Cash
2. Debit Card

The amount in the debit card is the only amount you can spend to stay within budget.

These method work because once you spend your money, you are done. You don’t have anything else to spend.

Credit cards, payday loans, and cash advances are all loans on future income. When you use a credit card, there is always just a little bit more you can spend. These types do not help you budget properly. In fact, these types encourage you to spend beyond your means and be out of budget.

As water is cooled from 4 deg C to 0 deg C, the water reaches its freezing point and starts forming ice crystals. Then the volume of that ice cubes increases and its density decreases. Hence, it is the reason that ice will float on water as ice has less density than the water.

Required number of 5 digit numbers can be formed by using the digits 1, 0, 2, 3, 5, 6 which are between 50000 and 60000 without repeating the digits are 

5 x 4 x 3 x 2 x 1 = 120.

The easiest way would measure it through half a liter water bottle. There are approximately 16.9 ounces(oz) of water in a 500ml water bottle.

Gallon is an imperial customary volume unit for the U.S.

As we have previously mentioned, the 16.9oz bottle is also known as 500ml in the metric system. According to U.S. standard, 1 gallon stands for 128 fluid oz.

Hence, Number of bottles in 1 gallon = 128/16.9 = 7.57 =~ 8.

Phoebus Levene was an organic chemist in the early 1900's. He is perhaps best known for his incorrect tetranucleotide hypothesis of DNA. He is who studied the structure and function of nucleic acids.

The discovery of Identification of Ribose and Deoxyribose is attributed to Phoebus Levene.

We can make an equation:

3(100000 + x) = 10x+1

(Why? Well, adding 100000 puts a 1 at the front of a five-digit number, and multiplying by 10 and adding 1 puts a 1 at the end of a number)

Solving this gives:

10x+1 = 3(100000 + x)
10x+1 = 300000 + 3x
10x = 299999 + 3x
7x = 299999
x = 299999/7 = 42857

The answer is 42857 (142857 is three times smaller than 428571).
