Answer:
6.8, 16.6, 26.4, 36.2
Step-by-step explanation:
Let's write the sequence, d is the common difference:
- 3, - 3 + d, - 3 + 2d, -3 + 3d, - 3 + 4d, 46
Therefore 46 = -3 + 5d
5d = 49
d = 49/5 = 9.8
So the first arithmetic mean is -3 + 9.8 = 6.8. and the second is -3 + 2(9.8) = 16.6...
They are:
6.8, 16.6, 26.4, 36.2.
There was 16 bagels, and now there is 0 bagels. So what you do is subtract 16 from 16 to get 0.
Answer: 90km/hour
Step-by-step explanation:
The formula for speed is given as:
= Distance / Time
where,
Distance = 120km
Time = 80 minutes = 80/60 = 1 1/3 hours
Speed = Distance / Time
= 120 / 1 1/3
= 120 / 4/3
= 120 × 3/4
= 90km/hour
The speed is 90km/hour.
