Answer: 16\dfrac{1}{2} pound rock is 1.571 times heavier than 10\dfrac{1}{2} pounds rock.

Step-by-step explanation:

Since we have given that

Quantity of rock = 16\dfrac{1}{2}\ pounds=\dfrac{33}{2}\ pounds

Quantity of another rock = 10\dfrac{1}{2}=\dfrac{21}{2}\ pounds

We need to find the number of times heavier is 16 1/2 pound rockthen a 10 1/2 pound rock.

so, number of times is given by

\dfrac{33}{2}\div \dfrac{21}{2}\\\\=\dfrac{33}{2}\times \dfrac{2}{21}\\\\=\dfrac{33}{21}\\\\=1.571

Hence, 16\dfrac{1}{2} pound rock is 1.571 times heavier than 10\dfrac{1}{2} pounds rock.

What are the values of the variables in the triangle below?
harkovskaia [24]

Answer:

D) x=9 ; y=3√(3)

Step-by-step explanation:

Sin(30)=\cfrac{y}{6\sqrt{3} }

\cfrac{18y}{6\sqrt{3}}=18\sin \left(30^{\circ \:}\right)

\sqrt{3}y=9

\cfrac{\sqrt{3}y}{\sqrt{3}}=\cfrac{9}{\sqrt{3}}

y=3\sqrt{3}

~

Cos(30)=\cfrac{x}{6\sqrt{3} }

\cfrac{18x}{6\sqrt{3}}=18\cos \left(30^{\circ \:}\right)

\sqrt{3}x=9\sqrt{3}

\cfrac{\sqrt{3}x}{\sqrt{3}}=\cfrac{9\sqrt{3}}{\sqrt{3}}

x=9

Therefore, x=9 and y=3√(3)
