Answer: $12
Step-by-step explanation: Since all the tickets cost the same amount, then 180 which is the dividend means the total amount of money needed by the sixth grade science club
15 is the divisor and it represents the total number of tickets needed
The quotient is $12
So the cost of one ticket is $12.
For prisms, use the formula: 2B + Ph
B = base of figure, here it is the trapezoid.
The area of the trapezoid is (3+6)*4/2 = 18
P = perimeter of the base, which is 3+4+5+6 = 18
h = height, here it is 5.
Thus the answer is:
2*18 + 18*5 = 36 + 90 = 126 cm^2
