Answer:
Step-by-step explanation:
The speed against the wind is ...
4680 mi/(8 h) = 585 mi/h
The speed with the wind is ...
5720 mi/(8 h) = 715 mi/h
The speed of the airplane in still air is the average of these speeds:
(585 +715)/2 = 650 mi/h . . . speed in still air
The speed of the wind is the difference between the airplane speed and the speed in the wind:
715 -650 = 65 mi/h . . . speed of the wind
_____
<em>Additional comment</em>
If p and 'a' represent the speeds of the plane and the air, the speeds with and against the wind are ...
p + a = with
p - a = against
If we average these, we get ...
((p +a) +(p -a))/2 = (with + against)/2
p = (with + against)/2 . . . . . . . the formula we used above
You've found the prime factorization when all of your factors are prime. They can't be divided into any smaller factors.
Answer:
1/36 = 0.02777...
Step-by-step explanation:
Given the sequence 1, 0.25, 0.111..., 0.0625, 0.04, you would like to know the next term.
<h3>Terms</h3>
We recognize the decimal values to be equivalent to ...
1, 1/4, 1/9, 1/16, 1/25
That is, they are the reciprocals of successive squares.
<h3>Next term</h3>
The next term will be the reciprocal of the 6th square:
1/36 = 0.02777...
Answer:
1) 144 seconds
2) 12
3) 24
Step-by-step explanation:
1) First off how many times can 15 dived into 90? 6! So we know it <em>can</em> go into 90 and that it's by 6. Next is to add 24 (seconds) 6 times. This will lead you too 144. So 144 seconds is your awnser
2) All you have to do is dived 72÷6. Which gives you the amount of each pack .
3) You take the total of step number two and 288 earsers and dived. so 288÷12=24
