Given that 100.48 = x, 100.70 = y and xz = y2 , then the value of z is close to:
1.45
1.88
2.9
3.7
Explanation:
xz = y2 $\Leftrightarrow$ 10(0.48z) = 10(2 x 0.70) = 101.40
$\Rightarrow$ 0.48z = 1.40
$\Rightarrow$ z =$\dfrac{140}{48}=\dfrac{35}{12}$= 2.9 (approx.)
xz = y2 $\Leftrightarrow$ 10(0.48z) = 10(2 x 0.70) = 101.40
$\Rightarrow$ 0.48z = 1.40
$\Rightarrow$ z =$\dfrac{140}{48}=\dfrac{35}{12}$= 2.9 (approx.)
