During a thunderstorm yesterday, 600 millimeters of rain fell in 30 minutes. What is the unit rate for millimeters per minute? Describe a situation in which it would be useful to know this unit rate. Explain why the unit rate would be useful. thank you in advance!!!

20mm/min

because if there is 600mm of rain in 30 min then to find out how much came in 1 min is to divide 600/30 which comes out to 20/1.

this unit rate would be important if you needed to measure how much rain came every year to see the difference in weather its increasing or decreasing.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
