how would the model and answer in the example problem change if Felicia live 7/10 mi from the soccer field then not 1 and 1/5 it's about fractions by the way ;)

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'.

30

step-by-step explanation:

times by times

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
