Question

HELPP MEEEEEEEEEEEEEEEEEEEEEe

Answer 1

A. The difference in ACTUAL divided by the difference in BLUEPRINT for each of the values must be equal.

`(6-3)/(8-4) =(12-8)/(9-6) =(16-12)/(12-9) =(20-16)/(12-12) = (24-20)/(18-15)`

B.
`(Actual)/(Blueprint)=(3\ ft)/(4\ in)/(4)/(4)=(0.75\ ft)/(1\ in)`

C. y = 0.75x

x = 21 in y = 7 ft

y = 0.75(21) 7 = 0.75x

y = 15.75 ft
`(7)/(0.75)=x`

`9(1)/(3)\ in = x`
