Which of the following best describes the English expression the quotient of nine and the sum of a number and one
1 answer:
Quotient of means divide and the placement of the symbol is where the word "and" is located... the closest "and" unless you see "sum of", "product of", "difference of", or even another "quotient of" between it and "and".
In this case the first "and" is closest so the division sign will go there and the 2nd "and" will be replaced with a + sign.
Ways to write the answer:
9 ÷ (x + 1)

<h3>What are Scientific notations?</h3>The way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.
For example, 6,500,000,000,000 can be written as 6.5×10¹².
As the value of the scientific notation is given 2.4x10⁻⁴, therefore, for bringing it in the standard form we need to shift the decimal to the left by four digits. So,
Hence, the value of the number 2.4x10⁻⁴ in the standard notation is 0.00024.
