Mathematics
1 answer:

Answer:

BC = 28 \frac{1}{3} ft

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{AX}{AB} = \frac{XY}{BC} , substitute values

\frac{12}{20} = \frac{17}{BC} ( cross- multiply )

12BC = 340 ( divide both sides by 12 )

BC = \frac{340}{12} = \frac{85}{3} = 28 \frac{1}{3}

Answer:  3\dfrac{2}{6}\ h

Step-by-step explanation:

Given

Rami practices his saxophone for \frac{5}{6} hour on 4 day each week

So, for a week she practices around

\Rightarrow \dfrac{5}{6}\times 4\\\\\Rightarrow \dfrac{20}{6}

Converting it into mixed fraction

\Rightarrow \dfrac{20}{6}=\dfrac{18+2}{6}\\\\\Rightarrow 3\dfrac{2}{6}\ h
