Poster standard dimension: 8.5 inches by 11 inches
Both length and width of the poster may vary 1/20%
∴ length and width may vary 1/20 % = 0.05% = 0.0005
∵ Area = Width * Length
∴ Area = 8.5 * 11 = 93.5 in²
Smallest acceptable area for one poster:
Width: 8.5 * (1 - 0.0005) = 8.49575 in.
Length: 11 * (1 - 0.0005) = 10.9945 in.
∴ The smallest area = 8.49575 * 10.9945 = 93.4065 ≈ 93.407 in².
The required distance is 16.40 km.
This problem can be solved if we know the concept of speed, time and distance.
We know the speed=
To solve the problem let us assume that the total distance between the workplace and home is x km.
Given that his speed while going from home to work is 45 mph and while returning is 35 mph.
Time for the complete journey is
.
Now according to question;

⇒
⇒
⇒ 
∴ 
So, the required distance is 16.40 km.

Answer:
Good, this question will probably get taken down though. That happened to me.
Step-by-step explanation:
Answer:
x = 
Step-by-step explanation:
Distribute parenthesis on both sides of the equation.
3x - 3 - 4x - 2 = 8x - 8 ← simplify left side
- x - 5 = 8x - 8 ( subtract 8x from both sides )
- 9x - 5 = - 8 ( add 5 to both sides )
- 9x = - 3 ( divide both sides by - 9 )
x =
=
= 
-7 =

+ 14
take 14 to the other side
-7 -(14) =

-21 =

Multiply by 3 on either sides to isolate e and to find a value
-21 × 3 =

× 3
3 and 3 cancels out
-63 = e
