If he goes to bed at 9:00 pm, and wakes up at 10:00 am he will have slept 13 hours.
Answer:
Step-by-step explanation:
The force is 1.6N and the distance between them is 1.3 meters
<h3>The force between them</h3>
An inverse variation from force to the square of distance is represented s:
k = Fd^2
Where k represents the variation constant
When F = 10, d = 2.
So, we have:
k = 10 * 2^2
k = 40
Substitute k = 40 in k = Fd^2
Fd^2 = 40
When d = 5, we have:
F * 5^2 = 40
This gives
25F = 40
Divide by 25
F = 1.6
Hence, the force is 1.6N
<h3>The distance between them</h3>
In (a), we have:
Fd^2 = 40
When F = 25, we have:
25 * d^2 = 40
This gives
25d^2 = 40
Divide by 25
d^2 = 1.6
Take the square root of both sides
d = 1.3
Hence, the distance between them is 1.3 meters

Multiply -1 (the - sign is equal to -1) to both numbers in the parenthesis.
-1 * 3x = -3x
-1 * -8 = 8
So now the equation looks like....
10x - 3x + 8
Now combine like terms.
10x - 3x = 7x
7x + 8 is the answer.
**I had a hard time reading what you wrote there because it was not really that clear. Perhaps giving me a screen shot next time would make it easier for me. Thanks!
