We are given a rain gutter made from folding a 12 inch wide aluminum sheet to an angle theta. The area of the opening is expressed as A(Θ) = 16 sin Θ (cos Θ + 1) where <span>Θ = 60°. we can just substitute directly the angle in degrees mode in the calculator and the answer is equal to 20.78 inches2.</span>
There are 16 dry ounces<span> in a pound. </span>
An octahedron in geometry is defined as a polyhedron with eight faces, six vertices and twelve edged. The term is used for regular octahedron mostly.
Thus we can summarize it as:
Number of edges: 12
Number of faces: 8
Number of faces: 6
the answer is 12 edges.
Given
Find out the what was the insurance company's payment .
To proof
As given
Sally Jones pays $50.00 a month for group health insurance
There is a $300 deductible
Her medical bills for the last year were $2,600.00
Linda's insurance company provided payment of 80% of the bills less the deductible.
Deductible
The amount of money you will pay in an insurance claim before the insurance company starts paying you.
medical bill reducing the deductible = $2,600 - $300
= $2300
80 % is written in the decimal form

= 0.8
than the equation becomes
Linda's insurance company provided payment = 0.8× 2300
= $1840
Therefore the the insurance company's payment be $1840 .
Hence proved
