Question

Water is steadily dripping from a faucet into a bowl. You want to write an equation that represents the number of milliliters y of water in the bowl after . What is the constant of proportionality for the relationship between the number of milliliters y of water in the bowl and the time in seconds​ x? What is the​ equation? Water from Dripping Faucet Time in Seconds​ (x) Milliliters in Bowl​ (y) 20 320 35 560 45 720 60 960

Answer 1

9514 1404 393

Answer:

• k = 16
• y = 16x

Explanation:

y is proportional to x when it satisfies the equation ...

y = kx

where k is the constant of proportionality. The equation can be solved for k by dividing by x:

k = y/x

The value of k for the given relation is ...

k = (320 mL)/(20 s)

k = 16 mL/s . . . the constant of proportionality

Then the equation is ...

y = 16x
