This is just a porportion. So if 250 meters is 1 meter than: 250/1
And it wants to know the height. So we have the first number but not the second. So we'll use x: 212/x
Set them equal to each other 250/1=212/x
Cross multiply: 212=250x
Divide to find x: 212/250=x
x=212/250
x=0.848
So the height of the model, to the nearest 10th would be 0.8 meters.
Answer:
k = a^2 + b^2/ ab + 1
Step-by-step explanation:
Answer:
We conclude that


L.H.S = R.H.S
Step-by-step explanation:
Given the property expression

Given that:
<u>Determining the LEFT-HAND SIDE</u>

substituting a= -3/5, b= 5/9 and c= -10/3




<u>Determining the RIGHT-HAND SIDE</u>

substituting a= -3/5, b= 5/9 and c= -10/3






Apply the fraction rule: 
Therefore, we conclude that


L.H.S = R.H.S
