Answer:
value of gold is $33.17
Step-by-step explanation:
given data
depth d = 3800 m = 3.8 km
area A = 3.63 × 10^8 km²
average concentration = 5.8 × 10^−9 g/L
price of gold = $129.00 / troy oz
to find out
value of gold
solution
first we find volume that is
volume v = A× d
put here value
volume = 3.8 × 3.63 × 10^8
volume = 13.794 × 
km³
volume = 137.94 × 
L
so mass = 5.8 × 
× 137.94 ×
mass = 8 × 
g
mass = 0.2572 troy oz
here we know 1 troy oz = 31.1 g
and we know 1 troy oz = $129
so 0.2572 troy oz = 129 × 0.2572
0.2572 troy oz value is $33.17
value of gold is $33.17

Combine Like Terms:
=−3p3+5p+−2p2+−4+−12p+5+8p3
=(−3p3+8p3)+(−2p2)+(5p+−12p)+(−4+5)
=5p3+−2p2+−7p+1
Answer:
=5p3−2p2−7p+1
Answer:
$936.32
Step-by-step explanation:
To solve this problem we need to find the remaining 12% of money our neighbor has saved since 88% was $836. To do this, we simply multiply $836 by 12%. Remember to change 12% into its decimal form (12% -> 0.12).
$836 x 0.12 = $100.32
Now, our last step is to add $100.32 to $836.
$836 + $100.32 = $936.32
Our answer is $936.32.
