Constant of proportionality​

Mathematics
1 answer:
Vadim26 [7]3 years ago
8 0

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

Vera_Pavlovna [14]

Answer: a. 4,700 mh

Assuming:

1 mh = 10^{-3} h

1 kh = 10^{3} h

1 ph = 10^{-12} h

The only option that is correct is a. 4,700 mh, let's prove it with the following conversion:

4.7 h \frac{1 mh}{10^{-3} h} = 4,700 mh
