Answer:
D) 15
Step-by-step explanation:
The sum of the interior angles of a polygon is given by
We have that, the sum of the interior angles of a polygon is
26 right angles. We want to find n, the number of sides.
We substitute into the formula to get:
Divide through by 90
Divide through by 2
So, out of 60 balls, 48 passes and 12 did not that gives us a failure rate of 20%
20% of 2500 = 2000 hence 500 balls would not pass inspection,
Let the price of the tickets be 'x' and the number of tickets bought is 'y'
When the y inversely proportioned to x, the equation is
y = k/x where k is a constant
We work out the value of k by using the information y = 6 and x = 5
6 = k/5
k = 30
Hence, the maximum number of tickets when the price is $3 is
y = 30/3
y = 10 tickets
Answer:
<h2>82 in²</h2>
Step-by-step explanation:
The median of the four numbers a, b, c and d. Where a ≤ b ≤ c ≤ d:
We have
84in², 72in², 80in², 84in² → 72in², 80in², 84in², 84in²
The median:
