Earth's oceans have an average depth of 3800 m, a total area of 3.63 × 108 km2, and an average concentration of dissolved gold o

Phoenix [80]

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 × $10^{8}$ km³

volume = 137.94 × $10^{19}$ L

so mass = 5.8 × $10^{9}$ × 137.94 × $10^{19}$

mass = 8 × $10^{12}$ 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

Does 65-(45-20)equal (65-45)-20? how do you know?

quester [9]

No, it does not. 65-(45-20) is equal to 40, because you subtract 45-20 before because of the parentheses. When you do that, you get 25 then subtract 65-25, then get 40. Then, if you subtract 65-45 first and get 25, then subtract 25-20, you'll get 5.
