Let’s convert the number 25.4 into scientific notation step by step. Scientific Notation Format: Scientific notation represents numbers in the format a×10n where ∣a∣ < 10 and n is an integer. Step-by-step Conversion: Determine the “a” value: For the number 25.4, the digit “2” is the first non-zero digit. We want to place a decimal…
To find the actual yearly rate of interest, we will follow these steps: Let’s go step by step: Total = $1,500 + $3,500 = $5,000 Total = $1,500 + $3,500 = $5,000 We can now calculate the actual yearly interest rate using the given numbers. The extra cost paid by John by taking this deal…
Henry’s Law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas on the surface of the liquid, provided the temperature remains constant. Mathematically, it can be expressed as: C = KH×P Where: Significance of Henry’s Law constant (KH): The value of KH provides a…
In the context of calibration and quality control in analytical chemistry, a stock solution might be a primary standard (a compound of known purity). In contrast, a working standard would be a secondary standard (a solution prepared from the primary standard). The primary standard is used to prepare the secondary standard, and the secondary standard…
Each tool has its strengths and is suited for particular analyses and datasets.
Here’s an example of a relation on the set A = {1,2,3} which is reflexive and transitive but not symmetric: Let’s define the relation R on set A as R = {(1,1),(2,2),(3,3),(1,2),(2,3)} Therefore, the relation R is reflexive, transitive, but not symmetric.
Solution: From the question, it is given that the value of a new car is £18,000. The value of car decreased by 25% in the first year. Now we will find the value of the car after it decreased by 25% 25% of 18000=£4500 Value of car after it decreased by 25% = Initial value…
Verified Answer: A store offers packing and mailing services to customers. The cost of shipping a box is a combination of a flat packing fee of $5 and an amount based on the weight in pounds of the box, $2.25 per pound. Which equation represents the shipping cost as a function of x, the weight…
Step 1: Identifying the Initial and Final Prices The initial step in this problem is to identify the starting and ending prices of the toy. According to the question, the toy initially costs £50, and the price is increased to £65. Step 2: Understanding Percentage Increase The concept of “percentage increase” refers to how much…
