The length of the wingspan of the finished model based on the dimensions of the kit is 0.75 feet
Given:
Kit
Plane = 27 feet
wingspan = 18 feet
Model:
Plane = 13.5 inches
Wingspan = x feet
convert 13.5 inches to feet
1 feet = 12 inches
13.5 inches = 1.125 feet
So,
equate Ratio of plane to wingspan
27 : 18 = 1.125 : x
27/18 = 1.125 / x
cross product
27 × x = 18 × 1.125
27x = 20.25
x = 20.25/27
x = 0.75 feet
Therefore, the length of the wingspan of the finished model based on the dimensions of the kit is 0.75 feet

Answer:
$19.60
Step-by-step explanation:
Given data
number of pages= 136 pages
number of copies = 19 copies
Hence 19 copies make a total of = 136*19
=2584 pages
hence if 500 pages cost $3.80
then 2584 pages will cost x
cross multiply
500x= 2584*3.8
500x=9819.2
Divide both sides by 500
x= 9819.2/500
x= 19.6384
x=$19.60
It will cost $19.60

Answer:
$9.87
Step-by-step explanation:
first, find the cost per pound:
$16.45: 5 pounds
divide both sides of the ratio by 5
$3.29: 1 pound
Then, multiply both sides by 3 to find the cost for 3 pounds
$9.87: 3 pounds
28x20=560
7x3=21
560-21=539
539*2=269.5
