The stretch of a spring in millimeters is proportional to the weight in grams attached to the end of the spring. Find the unit rate. (1 point) mm per gram
The unit rate in this case would be expressed as "mm per gram."
To find the unit rate, we need to determine the amount of stretch in millimeters for each gram of weight attached to the spring.
From the given image, we can see that the stretch of the spring is directly proportional to the weight attached to it. The unit rate can be determined by finding the constant of proportionality.
Let's say that for every gram of weight added to the spring, it stretches "x" millimeters.
Therefore, the unit rate is x millimeters per gram.
To find the unit rate, you need to determine the amount of stretch in millimeters per gram of weight.
Look at the graph or image provided, which shows the relationship between the stretch of the spring in millimeters and the weight in grams.
Identify a set of data points on the graph, such as (10 mm, 100 g) and (20 mm, 200 g). These points represent the stretch of the spring and the weight attached to it.
To find the unit rate, divide the change in the stretch of the spring by the change in weight. In this case, let's use the points (10 mm, 100 g) and (20 mm, 200 g).
The change in stretch is 20 mm - 10 mm = 10 mm.
The change in weight is 200 g - 100 g = 100 g.
Now, divide the change in stretch by the change in weight to find the unit rate:
10 mm ÷ 100 g = 0.1 mm/g.
Therefore, the unit rate is 0.1 mm per gram.
