Represent each of the following variables in the appropriate letters.Next determine wether the variable has a fixed value or a c
hanged value. a)The score Sarah got in a Mathematics test. b)The distance between the Zen house and the school. c)Temperature on the summit of Mount Everest in a day.
a) Let 'm' represents score in a Mathematics test. The variable has a fixed value because the marks Sarah obtained in her test will not change
b) Let 'd' represent the distance between the Zen house and the school. The variable has a fixed value because by using the same route, the distance will always remain constant.
c) Let 't' represent the temperature on the summit of Mount Everest. The variable has a changed value because the temperature may alter depending on the time of day and also climatic conditions which will affect the temperature.
The dimension of the document is 35 inches by 40 inches. It is redrawn at a scale of 1 1/2 or 3/2 or 1.5 The dimension will be: 35 * 1.5 = 52.5 in 40 * 1.5 = 60 in
Then redrawn again at 1/4 or 0.25 52.5 * 0.25 = 13.125 in 60 * 0.25 = 15 in
So the final dimensions of the drawing is 13.125 in by 15 in
