Which equation would best solve the following problem? tania releases a javelin 1.2 meters above the ground with an initial vertical velocity of 20 meters per second. how long will it take the javelin to hit the ground? –16t² + 20t + 1.2 = 0 –4.9t² + 20t + 1.2 = 0 –4.9t² + 20t = 1.2 –4.9t²+ 1.2t + 20 = 0

I think its the second answer

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'.

y=x+9
