The length of a model car is 1/20 of the length of the actual car. If the model. is 8.7 inch long, how long is the actual car? E

madam [21]

This means that if the model is 1 in lengh then th ereal car is 20 times of that or 20 in legnth

so to find the answer, just multiply model by 20
8.7 =model
real=8.7 times 20=174
real car is 174 inches

12 inches=1 foot
conversion factor
1 ft/12in=1=convesion

so
174 times 1/12=14 and 6/12

the answer is 14 feet and 6 inches or 14.5 feet

Unsure how your teacher wants the table to be filled out, but the solution is about 1.62.

$x = 1.75, f(x) =1.0625, g(x) =.75 \\ \\ 
x = 1.64, f(x) =.6896, g(x) =.64 \\ \\ 
x = 1.63, f(x) =.6569, g(x) =.63 \\ \\ 
x = 1.62, f(x) =.6244, g(x) = .62 \\ \\ 
x = 1.61, f(x) = .5921, g(x) = .61$
