Casandra finds a treasure chest packed with metallic coins. The chest has a volume of 0.25^30.25 m
Vladimir [108]

Answer:

Gold

Step-by-step explanation:

<em>Casandra finds a treasure chest packed with metallic coins. The chest has a volume of 0.25 cubic meters. The coins have a combined mass of 4825 kg. Hoping to find gold, she calculates the density to determine the metal of the coins.</em>

<em>What kind of metal are the coins made of?</em>

<em>Bronze (8700 kg per cubic meter)</em>

<em>Silver (10500 kg per cubic meter)</em>

<em>Lead (11300 kg per cubic meter)</em>

<em>Gold (19300 kg per cubic meter)</em>

<em />

Density is mass per volume:

D = M / V

D = (4825 kg) / (0.25 m³)

D = 19,300 kg/m³

The coins must be made of gold.

A car travels 10km southeast and then 15 km in a direction 60 degrees north of east. What is the magnitude of the car's resultan
Maurinko [17]

Answer: 15.85km

Step-by-step explanation:

The car starts at the point (0,0)

Let's define east as the positive x-axis and north as the positive y-axis.

first, the car travels 10km southeast, so the angle is -45° from the east.

Then the new position of the car is:

(10km*cos(-45°), 10km*sin(-45°)) = (7.07km, -7.07km)

Now, from this point the car travels 15km with an angle of 60° (counting from the east)

So the new position is:

(7.07km + 15km*cos(60°), -7.07km + 15km*sin(60°)) = (14.57km  , 5.91km)

The magnitude of a vector (x, y) is √(x^2 + y^2)

So the magnitude of the vector (14.57km  , 5.91km) is:

√((14.57km)^2 + (5.91km)^2) = 15.85km
