Answer: 14 new users are added per second
Step-by-step explanation:
1,200,000/24 = 50000
50000/60 = 833.333333333
833.333333333/60 = 13.8888888889
then round because it said on average
so if we round 13.8888888889 we get 14
so on average 14 new users are added per second.
Two dimes and six pennies
Answer: the angle is 1°+n×120°
1°, 121°, 241°
Step-by-step explanation:
Angles are taken modulo 360°, so 363° = 3°.
Angle plus supplement gives 180°.
Let a be angle, s be supplement of a.
So s = 180-a. Given a = 3 + 2s
a = 3 + 2(180 - a)
a = 3 + 360 - 2a = 363 - 2a
3a = 363° or 3° or 723°
a = 121° or 1° or 241°
a = 1°
s = 179°
2s = 358°
2s+3 = 361° = 1° (modulo 360)
a = 121°
s = 180-121 = 59°
2s = 118°
2s + 3 = 121°, as required.
a = 241°
s = 360+180-241 = 540-241 = 299
2s = 598
2s + 3 = 601 = 241 (modulo 360)
The greatest common factor for these two numbers is 6 because if you divide 24 by 6 you get 4 and if you divide 84 by 6 you get 14.
9 - 3 ÷ 1/3 + 1
BODMAS says that the first thing we do in this is the division (D), so 3 ÷ 1/3 = 9
9 - 9 + 1
Now we do the addition, 9 + 1 = 10
9 - 10 = -1
So your final answer is -1, I hope this helps!
