Step-by-step explanation:On a rectangle two sides will always be the same and the other two sides will be different but the same as each other. One side of a rectangle is 12 & there is another side of 12( perimeter is all sides added together ), so add 12+12=24 and then subtract 38-24=14( 14 is the two sides left added together , so 14•/•2 =7. 7+7=14, 12+12=24 ; 14+24=38. You can also add each number individually to check.

according to newton’s cannonball model, what happens if the cannonball's velocity is enough to overpower the pull of earth’s gravitystep-by-step explanation:

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'.
