Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…

Chapter 2.2, Problem 97E

Acidity of a solution A common measure for the acidity of a Solution is its pH . It is defined by p H = - l o g ⁡ [ H + ] , where H + measures the concentration of hydrogen ions in the solution. The pH of pure water is 7 . Solutions that are more acidic than pure water have a lower pH, while solutions that are less acidic (referred to as basic solutions) have a higher pH .

a. Acid rain sometimes has a pH as low as 4 . How much greater is the concentration of hydrogen ions in such rain than in pure water?

b. A typical mixture of laundry soap and water for washing clothes has a pH of about 11 , while black coffee has a pH of about 5 . How much greater is the concentration of hydrogen ions in black coffee than in the laundry mixture?

Susan is a volunteer at the SPCA and has a 2-hour shift per day. Occasionally she assists the vet with health checks. She also handles a few admin duties. The vet is open 6 days a week. Monday to Saturday from 08:30 to 16:30. 4.1Calculate Susan’s total volunteer hours per week.   4.2A dog’s normal temperature is between 101,5˚F to 102,5˚F. If a dog has a temperature of 38,8˚C, will it fall in the normal temperature range or is the dog feverish?  Use the formula ˚F= (˚C x 1,8) + 32  to confirm your answer.   4.3The vet’s weight is 67,76 kg. While holding the dog in her arms their weight is 89240g.Determine the weight of the dog to the nearest kilogram.
Prices of diamonds are determined by what is known as the 4 Cs: cut, clarity, color, and carat weight. The prices of diamonds go up as the carat weight increases, but the increase is not smooth. For example, the difference between the size of a 0.99-carat diamond and a 1-carat diamond is undetectable to the naked human eye, but the price of a 1-carat diamond tends to be much higher than the price of a 0.99 diamond. In this question, we use two random samples of diamonds, 0.99 carats and 1 carat, each sample of size 23, and compare the average prices of the diamonds. In order to be able to compare equivalent units, we first divide the price for each diamond by 100 times its weight in carats. That is, for a 0.99-carat diamond, we divide the price by 99. For a 1 carat diamond, we divide the price by 100. The distributions and some sample statistics are shown below I have attached the questions and the chart in the images section. Thank you
