Alan solved the proportion StartFraction x over 200 EndFraction = StartFraction 8 over 25 EndFraction as shown. StartFraction x
over 200 EndFraction = StartFraction 8 over 25 EndFraction. (8) (x) = (25) (200). 8 x = 5,000. StartFraction 8 x over 8 EndFraction = StartFraction 5,000 over 8 EndFraction. X = 625. What is Alan's error?
C. He mixed up the positions of 8 and 25 in the equation (8) (x) = (25) (200).
Step-by-step explanation:
So, he mixed up the positions of 8 and 25 in that equation because he was trying to use cross products. He didn't cross-product them correctly, it was supposed to be 25x = 8 (200), but instead he just multiplied the numbers beside the other. I don't know if this makes sense and I'm sorry if it doesn't, but hope it does! ^^
Answer: These are called rigid transformations because the structure and shape of the shape remains the same.
Step-by-step explanation: The word rigid and rigidity is often used to describe something that is tough or the strength of something. The transformations might be called a rigid transformation because the rigidity of the shape remains the same because the size is the exact same, it is the exact same shape it is just moved.
