If a line has a slope of 3/4, what is the
slope of the line perpendicular to the
line?

The answer is -4/3

Step-by-step explanation:

Te reason why is because if it's perpendicular the slope will be the opposite reciprocal and will equal -1. So multiply 3/4*-4/3 and it will get you -1!

Hope this helps! I also just took the test so it's right!

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'.
