Answer:
B
Step-by-step explanation:
Given that r is inversely proportional to s then the equation relating them is
r =
← k is the constant of proportion
To find k use the condition r = 16 when s = 3
k = rs = 16 × 3 = 48
r =
← equation of variation → B
The answer to your problem is f(x)= -12 (x-4)
15/50 = 0.3
that’s 30%
so 30% of people will not be wearing hats.
30% of 250 = 250 x 0.3
= 75 people
She can bake 48 muffins in 90 minutes. Since she can bake 24 in 45 min, 90 min is double that, so double the original amount of cupcakes. 24x2=48
