2.99 • 7% = 0.2093
2.99 + 0.2093 = 3.20
Answer 19:1
Work:
Students scoring above 80 -
9+18+72+15= 114
Students score exactly 80-
6
114/6 = 19
19 students scored above 80 for every 1 student that scored exactly 80.
That's a pretty confusing one. I think it's 10 minutes.
Answer: x = 9
Step-by-step explanation:
The sum of three interior angles of a triangle is 180°.
(9x - 3) + (6x) + 48° = 180°
9x - 3 + 6x + 48 = 180
15x + 45 = 180
15x = 135
x = 9
Complementary angles add up to equal 90 degrees. Knowing this, you can subtract 68 from 90. 90-68=22.
Hope this helps.
