Chandler was a caretaker at the state zoo. he noticed that the number of animals adopted by the zoo increases at a constant rate every year since 2010 which of the following graphs shows the slowest rate at which the animals in the zoo were adopted?

Option C.

Step-by-step explanation:

To find the trend of adoption of the animals by the zoo we will find the slope of line given in each graph.

For graph B.

Given line is passing through two points (0, 3) and (2, 15)

Slope of the line

For graph C.

Given line is passing through (0, 12) and (4, 0)

Slope of the line in graph

In these two lines, line in graph C is showing negative slope which means adoption of animals by zoo is showing negative trend.

So Option C. is showing the slowest rate at which the animals in the zoo were adopted.

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'.
