Question

m varies inversly as d if m =12 men when d =10 find m when d =8 days​

Answer 1

m=15

Answer:

We have,

m inversely proportional to d

This means when m increases d decreases or vice versa.

So, m1 ×d1 =m2 ×d2

==> 12× 10=m×8

==> m= 12×10 /8 = 15

Answer 2

Answer:

If m varies inversely as d if m =12 men when d =10. So,  m= 15  when d =8 days​.

Step-by-step explanation:

$m ∝ \frac{1}{d} \\m =\frac{k}{d} (k constant)\\k = md$

If m = 12, d = 10, then k = ?

$k=md = 12 (10) = 120$

If d= 8, k = 120, then m = ?

$m=\frac{k}{d} \\=\frac{120}{8} \\m = 15$
