Ms. fox asked her class “is the sum of 4.2 and √2 rational or irrational? ” patrick answered that
the sum would be irrational.
state whether patrick is correct or incorrect. justify your reasoning.

Patrick is correct because √2 is irrational (It is a real number that can't be expressed as a ratio), and even if 4.2 is added, the sum still won't be able to be expressed as a ratio √2=approx. 1.41421, and √2 +4.2=approx.5.61421. The only change in the number is in the first two digits.

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'.
