Answer:
$1,250 a year
Step-by-step explanation:
25,000,000*0.0002=5000kg of zinc
5000/4=$1,250
So that is $1,250 a year.
Answer:
1.11
Step-by-step explanation:
If you know all the side lengths of a right triangle, you can use trigonometry ratios to find sines, cosines, and tangents.
sin(x) = opposite / hypotenuse
cos(x) = adjacent / hypotenuse
tan(x) = opposite / adjacent
If we are finding the tangent of angle X, we can see that the opposite side is 72 units and the adjacent side is 65 units.
Using the ratio, we can conclude that tan(x) = 72/65.
Use your calculator to divide, and you will get 1.10769, which is approximately 1.11.

This is an arithmetic sequence because each term is 7 greater than the previous term, so 7 is what is called the common difference...
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=first term, d=common difference, n=term number.
We know a=1 and d=7 so:
a(n)=1+7(n-1)
a(n)=1+7n-7
a(n)=7n-6
The above is the "rule" for the nth term.
