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.

The formula for the area of any triangle is as followed:
-------------------------------------------------------------------------------------------------------------
<u>Let Statements:</u>
Let the variable...
→ represent the length of the base of the triangle
→ represent the length of the height of the triangle
-------------------------------------------------------------------------------------------------------------
Using the information provided from the question, we can substitute its values in place of the variables and solve for the last remaining variable:
Distribute the parenthesis<em> (The Distributive Property) </em>:
Reduce the fraction to lowest terms:
Add -6 to both sides of the equation:
Divide both sides of the equation by 2:
-------------------------------------------------------------------------------------------------------------
The Answer to this Problem is:

Answer: 25
Step-by-step explanation: (x-a)² = x² - 2ax + a²
From x² - 10x + k we deduce that 10x = 2·5x and a = 5
Then k = 5²2
In mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.
