Answer:
The slope of ladder is not within the safe range .
Step-by-step explanation:
Given as :
The height of the ladder up a wall = h = 2 meters
The distance of base of ladder from the wall = x = 0.4 meters
The estimated safety range of slope of ladder is between 6.3 and 9.5
Let The slope of the ladder = x
<u>According to question</u>
slope of the ladder = 
Or, x = 
Or, x = 5
So, The slope of the ladder = x = 5
Since The estimated range of slope between 6.3 and 9.5
And The calculate slope of ladder = 5
Hence, The slope of ladder is not within the safe range . Answer

Answer:
see explanation
Step-by-step explanation:
We require 2 equations with the recurring part after the decimal point.
Let x = 0.555..... → (1)
Multiply both sides by 10, then
10x = 5.555..... → (2)
Subtract (1) from (2) thus eliminating the recurring decimal
(10x - x) = (5.5555 - 0.5555 ), that is
9x = 5 ( divide both sides by 9 )
x = 
Each line between 0 and 1 is 1/10 ( there are 10 lines)
First arrow is on the 3rd line so would be 3/10
The next arrow is 3 away from that so would be 3/10
The 3rd arrow is 2 away from the 2nd so would be 2/10
3/10 + 3/10 + 2/10 = 8/10
The answer is b
