Answer:

Option (G)

Step-by-step explanation:

Volume of the real cane = 96 in³

Volume of the model of a can = 12 in³

Volume scale factor = $\frac{\text{Volume of the model}}{\text{Volume of the real can}}$

= $\frac{12}{96}$

$=\frac{1}{8}$

Scale factor of the model = $\sqrt[3]{\text{Volume scale factor}}$

$=\sqrt[3]{\frac{1}{8}}$

$=\frac{1}{2}$

Therefore, scale factor of the model of a can = $\frac{1}{2}$ ≈ 1 : 2

Option (G) will be the correct option.

Answer:

2.3 units

Step-by-step explanation:

The unknown side is opposite the given angle 50 degrees, and the length of the hypotenuse is 3 units.

Since sin Ф = opp / hyp, we have here sin 50° = x/3, or x = 3 sin 50°.

Using a calculator, we find that the sine of 50° is 0.776.

Therefore, x = 3(0.766) = 2.298 units, or approximately 2.3 units
