Suppose you are told that 2 = 3' on a scale drawing. If there is
an object that measures 5" in the drawing, what would its actual
length be?
Figure out how many 1/2" are in 5" and then multiply by 3.
A
32
B
30
C 7.5

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

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

you need to give us more information since we can't answer

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
