Complete the equation of variation where y varies inversely as x and y = 80 when x = 0.7.

Step-by-step explanation:

We are given that y varies inversely with x.

y=80 when x=0.7

We have to write complete equation of variation

According to question

Where k=proportionality constant

Substitute the values then we get

using multiplication property of equality

Therefore, the equation is given by

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'.
