Question

Constant of proportionality​

Answer 1

Answer:

9.1) k = 4.6

9.2) k = 6

Step-by-step explanation:

9.1) $115 = k(25)$

To find constant of proportionality, k, divide both sides by 25

$\frac{115}{25} = \frac{k(25)}{25}$

$4.6 = k$

Constant of proportionality, k = 4.6

9.2) $15 = k(2.5)$

To find constant of proportionality, k, divide both sides by 2.5

$\frac{15}{2.5} = \frac{k(2.5)}{2.5}$

$6 = k$

Constant of proportionality, k = 6
