48
The answer to the question is 48
Answer:
Step-by-step explanation:
We need to first find the perimeter of this oddly-shaped rink. We have a rectangle for which we are enclosing 3 of its sides, and the fourth "side" is a half-circle. Let's find the perimeter (or circumference) of the circle, divide it in half because we have half a circle, then add in the remaining 3 sides from the rectangle, shall we?
C = πd. The diameter of the circle is the same as the shorter length in the rectangle, 26. Therefore,
C = (3.14)(26) so
C = 81.64 m for a whole circle, and for half of that circle, the circumference is
C = 40.82 m
Now we can find the perimeter of the rink:
40.82 + 61 + 26 + 61 = p so
p = 188.82 m
If the fencing costs $6.20 per meter and we have 188.82 m, then the total cost is
. The label "meter" cancels out, leaving us with
cost = $1170.82

Answer:
$2,185
Step-by-step explanation:
Multiply the amount spent by the tax rate.
23,000 x 9.5% = $2,185
Given:
8:03 = 188 empty seats
8:10 = 160 empty seat
188 - 160 = 28 empty seats
8:10 - 8:03 = 0:07 minutes
28 / 7 minutes = 4 empty seats per minute
8:00 - 8:03 = 3 minutes
3 minutes * 4 seats per minute = 12 seats
188 + 12 = 200 empty seats at 8:00
8:15 - 8:10 = 0:05 minutes
5 minutes * 4 seats per minute = 20 empty seats
160 - 20 = 140 empty seats at 8:15
200 - 120 = 80 empty seats
80 empty seats / 4 empty seats per minute = 20 minutes
120 empty seats at 8:20.
8:00 = 200 empty seats
200 / 4 = 50 minutes
8:00 + 0:50 = 8:50 is the time when there are no empty seats left.
