On Saturday, rain fell at a rate of 1.5 inches per hour. Write an equation to show the relationship between the number of hours, h , and Saturday's rainfall, r .

r = 1.5h will be the expression.

Step-by-step explanation:

Rate of rainfall on Saturday = 1.5 inches per hour

If the rainfall occurred for h hours then the total rainfall on Saturday = Rate of rainfall × Duration of rainfall

Therefore, total rainfall = 1.5h

If the total rainfall be represented by 'r', then the expression that represents the rainfall on that day will be,

r = 1.5h

Step-by-step explanation:

Let h represent number of hours an r represent Saturday's rainfall.

We have been given that on Saturday, rain fell at a rate of 1.5 inches per hour. So rain fell on Saturday in h hours would be .

Since r represents Saturday's rainfall, so total rain fell (r) on Saturday in h hours would be

Therefore, the equation shows the relationship between the number of hours and Saturday's rainfall.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
