Determine whether the quantities in the problem vary directly or inversely and then solve the problem.
a mill processes 48 tons of flour in 15 hours. how many tons of flour can the mill process in 20 hours if its rate or production stays the same?

Step-by-step explanation:

U have a direct proportion

48 tons of flour to 15 hrs = x tons of flour to 20 hrs

 48          x

= cross multiply

15          20

(15)(x) = (48)(20)

15x = 960

x = 960/15

x = 64 <  64 tons

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
