Aset of blueprints uses a scale on which half an inch represents 4 feet. if the blueprint of the house shows the house to be 18 inches wide, then the width of the actual house feet

The width of the actual house is 144 feet

Step-by-step explanation:

If 0.5 inch represents 4 feet and the blueprint of the house shows the house to be 18 inches wide, then the following proportion must be satisfied:

0.5 inch / 18 inches = 4 feet / x feet

x = 4*18/0.5

x = 144 feet

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
