Earl isn't correct: the number 1,456 represents the total number of tickets sold, rather than simply six times the number of tickets sold.
Let x= the discount ticket price
1456 = 6x + x
1456 = 7x
x = 28
28 discount tickets were sold. The total number of tickets sold is equal to both the number of discount tickets sold plus six times that number: 1,456 = 6x+ x. Solve for x.
Answer: After 8 hours the pressure will be at -60?
Explanation: not sure how the balloon can reach -60 kilopascals but 15% of 300 is 45 and 45 x 8(hours) is 360. 300 - 360 is -60
Answer:
27; C; B; D
Step-by-step explanation:
1. B = 120 degrees, and C = 60 degrees. Q = 90 degrees, because B + C = 180 degrees, and the triangle BQC has angle B and angle C bisected. If B = 120 degrees, then the height is equal to 9 sqrt 3, which makes BC equal to 27.
2.C
3. B (You don't actually know if any of the sides are parallel.)
4. D
