I need help ASAP . I'll give brainliest :3...

Question 3:

Since it does not start proportional, I would assume there was 1.6 meters already in the pond.

I would say the rate of change is 0.4 Meters per hour.

I believe this because in the last 2 hours it went from 2 meters to 2.8 meters.  This makes me believe there was 1.6 meters already because if you count the first hour you can do 2-0.4=1.6

In conclusion the rate of change is 0.4 Meters per hour.

For question 4:

The rate of change is $7.75 per hour or $7.75/hour

Step-by-step explanation:

I got this answer by finding how much Sarah makes per hour.

15.50=2 therefore if you divide both sides by 2 you get 7.75=1

7.75=1 means Sarah makes 7.75 per hour.

Then, to check my answer I multiplied the unit rate of 7.75=1 by 4

This gave me 31.00=4 or Sarah makes 31.00 for every 4 hours.

In conclusion, the rate of change is $7.75 per hour

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
