There are 48 students studying foreign language at the community college. if the only two foreign languages offered are french and spanish, and 28 students are studying french, which of the following represents the ratio of students studying spanish to the total number of foreign language students?

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'.

good luck on your studies! : )
