A non zero real number could be written as a/1.
When this gets reversed to be 1/a, it is the multiplicative inverse.
Answer: 1/2 or 0.5
Step-by-step explanation:
The common denominator you can calculate as the least common multiple of the both denominators and Subtract: 9
10
- 4
10
= 9 - 4

The pH of the substance is 3.
<u>Explanation:</u>
Given:
Concentration of hydrogen ion, [H⁺] = 10⁻³M
pH = ?
The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution.
pH = -log [H⁺]
pH = -log [10⁻³]
pH = 3 log [10]
pH = 3
The pH of the substance is 3 and since the pH is less than 7, the substance is acidic in nature.
Answer:
3/68
Step-by-step explanation:
probability of blue = 4/17
after blue is selected, total number decreases by 1
so, probability of green = no fo greens/total number = 3/16
so probabilty = 4/17 * 3/16
C
By the law of sines, where A, B, C are the angles and a, b, c are the lengths of the sides opposite their respective angles. In this case, is opposite 4.6 and A is opposite 3.2, so , giving the answer.
