How would you graph the solution to 3 x ≤ -15? a. draw an open circle on -5 and shade to the left. b. draw an open circle on -5 and shade to the right. c. draw a closed circle on -5 and shade to the left. d. draw a closed circle on -5 and shade to the right.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
