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.

Solve for x: 3(x + 1) = −2(x − 1) − 4.
Vlad [161]

Answer:

Multiply the first bracket by 3

Multiply the second bracket by -2

3x+3=-2x+2-4

3x+2x+3=-2x-2   negative (-) number and positive number (+)= negative number

Just rearranging

5x+3=-2

5x+3-3=-2-3

5x=-5

Dividing by 5

5x/5=-5/5

x=-1

Check answer by using substitution method

3(-1+1)=-2(-1-1)-4

0=-2(-2)-4 negative number and negative number = positive number

0=4-4

0=0

Answer is x=-1

torisob [31]

The perimeter of the equilateral triangle will be 76.2 in

<u>Explanation:</u>

Altitude of an equilateral triangle, H = 22 in

Perimeter, p = ?

Let a be the side of the triangle

We know:

H = \frac{a\sqrt{3} }{2} \\\\22 = \frac{a\sqrt{3} }{2} \\\\a = 25.4 in

Perimeter = 3a

P = 3 X 25.4 in

P = 76.2 in
