Step-by-step explanation:

Given that a certain family plan costs $55 per month plus additional usage costs.

If x is the number of cell phone minutes used above the plan amount and y is the number of megabytes of data used above the plan amount, interpret the following expressions

a) 0.25x means 1/4 of the cell phone minutes used above the plan amount

b) 2y means twice the megabytes of data used above the plan amt.

c) 0.25x+2y+55 means 1/4 of the cell phone minutes used above the limit + twice the megabytes of data used above the plan + fixed cost of 55 dollars.

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'.
