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.
Answer:
R = 3.057% per year
Step-by-step explanation:
This is a compound interest question
From the question, we have the following information
P = Principal = $1,725.95.
A = Amount after 25 years = $3,703.05
T = Time = 25 years
n = Compounding frequency = compounded monthly = 12
r = interest rate = ???
The formula to calculate the interest rate in a compound interest question =
r = n[(A/P)^1/nt - 1]
r = 12[($3,703.05/$1,725.95)^1/12× 25 - 1]
r = 3.057%
Therefore, the interest rate on the account is 3.057%
The three even integers are 80, 82, and 84.
The sum of the first (80) and the third (84) integers = 80 + 84 = 164, verifying our answer.
A simple way to figure this out is to divide 164 by 2, which gives you 82. From this answer, if we subtract 2 to get the first integer and add 2 to get the third integer while keeping 82 as the second integer, we end up with the correct sum of 164.
Hope this helps!
Answer:
no. because if you divide 4/15 you will get 0.266666.....
