Arectangle has a width of 5 inches and a length of 9 inches. what will be the new dimensions of the rectangle after it is dilated by a scale factor of 3? a) 8 inches by 12 inches b) 15 inches by 9 inches c) 15 inches by 27 inches d)45 inches by 81 inches

To solve this problem you must apply the proccedure shown below:

 1. When a rectangle is dilated by a scale of factor, you must multiply the original dimensions by this scale of factor to obtain the new dimensions.

 2. The original dimensions are: The width is  and the length is 

 3. Therefore, the new dimensions are:

 The answer is the option C: C)  by 

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
