The alloy contains 10.5 pounds of copper.
Answer:
1.65%
Step-by-step explanation:
We will assume the percentage was the same over the 5 years. The number of passengers using a railway is expressed by the formula

Where
P(t) is the number of passengers after 5 years
P(t) = 174,989
P₀ is the number of the passengers at the beginning of the period
P₀ = 190,205
r is the rate in percentage r = ?
t is time duration t = 5 years
Substituting these given values into the formula,


![1 - r = \sqrt[5]{ \frac {174,989}{190,205}}](https://tex.z-dn.net/?f=1%20-%20r%20%3D%20%5Csqrt%5B5%5D%7B%20%5Cfrac%20%7B174%2C989%7D%7B190%2C205%7D%7D)



r = 1.65%
The annual percentage decrease over the period of 5 years is 1.65%
Answer:
c) subtraction property of order
Step-by-step explanation:
To get from line 1 to line 2, 3 was subtracted from both sides of the inequality. The "subtraction property of order" says you can do that without changing the order or the solution.
It should not be a surprise that when subtraction is involved, the associated property has "subtraction" in its name.
