Abuilding is 200 ft long and 140 ft wide a 1/500 model is built of the building how long and how wide is the model

Given that length of the building = 200 feet

Given that width of the building = 140 feet

Now it says that "a 1/500 model is built of the building "

Which means they want to create a model with ratio 1 feet for each 500 feet.

So to find the length and width of the model we will simply divide given sides by 500.

Side length of the Model = 200/500 = 2/5 = 0.4 feet

Side width of the Model = 140/500 = 14/50 = 0.28 feet

Hence final answer is model will be of length 0.4 feet and width 0.28 feet.

step-by-step explanation:

where is the questions

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!
