Adoll factory needed to produce an order of dolls for a shop. the factory
planned to spend 24 days on the production at a rate of 1,500 dolls per
day. due to a technical improvement, the factory produced the dolls 1.6
times as fast as it normally would. how many days did it take the factory
to finish the order of dolls?

24 / 1.6 = 15

15 days

15 days.

Step-by-step explanation:

By proportion, that is 24 / 1.6

=  15 days.

15

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
