60t+20t=150
80t=150
t=150/80=15/8
Note: t is only half the time, the total time is 15/4=3 hours 45 minutes
Answer: <u>Acute and Obtuse</u>
Explanation:
The acute angle is the small angle that is less than 90°, and the obtuse angle is the bigger angle. It is more than 90° and is also less than 180°.
Hope this helps!
The questions are all obtuse.
Given:
2002 sold 1000 paperback books and 1500 hardback books for a total of 2,500 books.
2003 sold 15% more paperback books and 5% more hardback books.
1000 x 1.15 = 1,150 paperbacks
1500 x 1.05 = 1,575 hardbacks
1150 + 1575 = 2,725
2,725 - 2,500 = 225
225 / 2,500 = 0.09
0.09 x 100% = 9% choice C
74,672,652,600. Take the time of the show and multiply it by the number of times she laughs in a minute. Then multiply that by the number of shows she watches in a day. That number seems pretty large though so you may want to make sure you have the right numbers and that it's not just 5 times, 3 shows, and 40 minutes.
