Given: Z = 0.43Y + 12 ; What is Y when Z = 28

1 answer:

5 0

Z = 0.43Y + 12; Z = 28
28 = 0.43Y + 12; insert value of Z
16 = 0.43Y; subtract 12 from both sides
37.21 = Y; divide both sides by 0.43; rounded to nearest hundredth

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Polygon X is similar to polygon.

And Polygon X is three times the size of polygon Y.

So, it becomes,

$\dfrac{\text{Perimeter of polygon X}}{\text{Perimeter of polygon Y}}=\dfrac{3}{1}\\\\\dfrac{81}{x}=\dfrac{3}{1}\\\\x=\dfrac{81}{3}\\\\x=27$

Hence, perimeter of polygon Y is 27.

Therefore, Option 'C' is correct.
