Question

If m is inversely proportional to n and if m=0.02 ,when n= 5 find m when n = 0.2
please help I have exam today​

Answer 1

Answer:

0.02*5=0.2*m

0.01=0.2m

So m = 20

Answer 2

The value of m when n = 0.2 is 0.5

Step-by-step explanation:

From question, m is inversely proportional to n

m ∝ 1/n

m = k × 1/n

mn = k

From question, the value of m and n is 0.02 and 5 which is:

k = 0.02 × 5

∴ k = 0.1

Now, the value of m when n = 0.2 is:

0.1 = m × 0.2

m = 0.1/0.2 = 1/2

Thus, the value of m is:

∴ m = 0.5
