In the gift shop of the history of flight museum, elisa bought a kit to make a model of a jet airplane. the actual plane is 21 feet long with a wingspan of 17.5 feet. if the finished model will be 10.5 inches long, what will the wingspan be?

8.75 inches

Step-by-step explanation:

We are given that Elisa bought a kit to make a model of a jet airplane

The length of  actual plane=21 feet

The length of wingspan in actual plane =17.5 feet

In the model

Length of airplane=10.5 inches

We know that 1 foot=12 inches

Length of actual plane=

Length of wingspan in actual plane=

If a length of plane is large then length of its wingspan is large and if a plane is short then its wingspan is short also.

It is directly proportional

if x is directly proportional to y

Then  ,x=ky

Let x be the length of wingspan in model

Then, using directly proportional property

Hence,length of wingspan in model=8.75 inches

answer: howdy

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
