2 90

3 135

5 225

6 270

Find the constant of proportionality.


Use the constant of proportionality to write a unit rate for the data in the table.


Write an equation to represent the relationship between time, t, and distance, d.

Answers

Answer 1

Answer: Constant of proportionality is 45 miles per hour.

Step-by-step explanation: To find the constant of proportionality you need to do miles/hours. It is always easier to do the first one as it is the smallest and thus eliminates the need to do harder problems.

miles/hours

90/2 = 45

135/3=45

225/5=45 and so on...

Answer 2
answer is 45 as the proportional relationship

Answer:

Step-by-step explanation:

1: 14.03 x 0.8 = 11.224

14.03 ÷ 0.8 = 17.5375

So, 14.03 x 0.8 < 14.03 ÷ 0.8

2: 6.032 + 1.75 = 7.782

10.142 - 2.36 = 7.782

So, 6.032 + 1.75 = 10.142 - 2.36

3: 578 ÷ 34 = 17

414 ÷ 18 = 23

So, 578 ÷ 34 < 414 ÷ 18

4: 271 ÷ 8 = 33.875

15.05 + 18.825 = 33.875

So, 271 ÷ 8 = 15.05 + 18.825

5: 5.07 x 2.8 = 14.196

19.06 - 4.865 = 14.195

So, 5.07 x 2.8 > 19.06 - 4.865
