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 drop of oil makes a circular ring in a water puddle. The radius of the oil ring expands at 1.5 cm per second. If r(t)=1.5t and
Readme [11.4K]

Answer:

a(t) =n(0.25t^2)

Step-by-step explanation:

Given

r(t) = 0.5t

a(r) = nr^2

Required

Determine the area in terms of time

From the question, we have:

r(t) = 0.5t -> radius per time

and

a(r) = nr^2 --> area from radius

The interpretation of the question is to find the composite function: a(t)

If a(r) = nr^2, and r(t) = 0.5t, the

Substitute 0.5t for r

a(t) =n(0.5t)^2

a(t) =n*0.25t^2

a(t) =n(0.25t^2)
