Answer:
Answer C
Step-by-step explanation:
If the polygon has n sides, then the number of diagonals the polygon has is
(n - 3)*n/2
So for a seven sided figure the number of diagonals would be
(7 - 3)(7)/2 = 4*7/2 = 28/2 = 14
Answer:
117
Step-by-step explanation:
every time x goes up by one you add 5 to y
First find the area of the rectangle by multiplying the length and width of the rectangle, so 12 x25=300. Then find the area of the triangle, which is length x height/ 2. So 8 x 25=200/2=100. Then add the two answers together to get 400.
The amount of bill is $43.15
Step-by-step explanation:
Given,
Current meter reading = 25,789 kWh
Reading on last bill = 25,350 kWh
Reading for the month = Current meter reading - Last month bill reading
Reading for the month = 25789 - 25350 = 439kWh
Cost per kWh = $0.0983
Cost of 439 kWh = 0.0983*439 = $43.1537
Rounding off to nearest hundredth
Cost of 439 kWh = $43.15
The amount of bill is $43.15
