Answer:
The sum of all internal angles of this polygon is: 
Step-by-step explanation:
Recall that the formula for the number of diagonals of a polygon with n-sides is given by the formula:
and since Lucero noticed that the number of digonals was 7 more that the number of sides, then, these two quantities (n + 7) and the number of diagonals must be equal. we can set an equation stating such, and solve for "n" (number of sides of the polygon):
therefore n = 7 or n = -2
The only answer with meaning is the first one (7 sides), since a polygon must have a positive number of sides.
Now that we know the number of sides of the polygon, we can find what the sum of its internal angles should give, based on the equation;
Addition of internal angles of a polygon is = 
Which in our case renders:
Answer:
9 3/8 ounces of dog food
Step-by-step explanation:
1 cup = 1 7/8 ounces
1 7/8 + 1 7/8 = 2 14/8 = 3 6/8
3 6/8 + 1 7/8 = 4 13/8 = 5 5/8
5 5/8 + 1 7/8 = 6 12/8 = 7 4/8
7 4/8 + 1 7/8 = 8 11/8 = 9 3/8
Based on the amount borrowed and the interest per year, Big Brothers, Inc will pay an annual payment of $59,973.15.
<h3>How much will Big Brothers, Inc. pay annually?</h3>
This can be found by using the present value of an annuity formula because the annual payment will be constant and therefore like an annuity.
Formula is:
Present value of annuity = Annual payment x ( 1 - (1 + rate) ^ -number of periods) / rate
Solving gives:
267,999 = Amount x ( 1 - ( 1 + 18.16%)⁻¹⁰) / 18.16%
267,999 = Amount x 4.46865
Amount = 267,999 / 4.46865
= $59,973.15
