(15 PTS) Help me plz.

the first answer is 11.32

second answer is 6k-3

Step-by-step explanation:

you had to plus 2.19 three times, 0.59 three times, and 1.49 two  times.

like for example: 2.19+2.19+2.19= 6.57

                           0.59+0.59+0.59= 1.77

                                        1.49+1.49=2.98

and just plus the 6.57+1.77+2.98= 11.32

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'.

i’m here for points.
