Answer:
2%
Step-by-step explanation:
28/140=0.2
Answer:
1-1/3 if its 14
1/52 if its 1/4
Step-by-step explanation:
C(x) = 400 + 20x - 0.2x²
c(30) = 400 + 20(30) - 0.2(30)²
= 400 + 600 - 0.2(900)
= 1000 - 180
= 820
It costs $820 when 30 radios are produced.
Marginal cost is how much it would cost to make one MORE of the same product so now we find how much it costs to produce 31 radios and compare the two.
c(31) = 400 + 20(31) - 0.2(31)²
= 400 + 620 - 0.2(961)
= 1020 - 192.2
= 827.8 or ≈828.
Now we find the difference which means we subtract the two.
828 - 820 = 8.
Your marginal cost is $8.
To compare we can also do 29 radios.
c(29) = 400 + 20(29) - 0.2(29)² = 811.8 or ≈812
820 - 812 = 8.
Answer:
The BLM presents awards to companies that minimize negative effects on the environment while mining natural resources. One such award is called the Hardrock Mineral Environmental Award. The BLM awards it to the mining company that has best fulfilled federal, state, or local requirements with little help from government agencies.
How does giving this award help the BLM more effectively manage land resources?
It prevents the companies from mining land resources such as gold and coal.
It informs companies about which minerals can be mined and which cannot be mined.
It encourages companies to follow rules set by government agencies.
It educates the companies about ways hard rock mining can destroy land resources.
