Answer:
The top of the ladder is now at 10 ft.
Step-by-step explanation:
At the start, we have a height H=6, a length L=10 and a base B, that has to be calculated by the Pythagorean theorem:
The base is moved twice the distance the height moves up.
We called this distance x, so we have:
The new height (H+x) is
The base travels 2x=8, so the new base B' is 0.
This means that the ladder is all against the wall (L=H').
Formula:

To solve this problem do this: ( 3 x 5 x 8 ) - ( 2 x 8 ) = 104
Answer:
1 - 4/5-(-1/5)
Step-by-step explanation:
1. - 4/5-(-1/5)
= -0.8+0.2 (if there is a minus sign inside and outside of the parenthesis, when we destroy that parenthesis, both the minus signs will be multiplied and becomes a (+).) (Making it to the percentile).
= -0.6
2. - 4/5-1/5
= -0.8-0.2
= -1
3. -(4/5+1/5)
= -(0.8+ 0.2) (Making those to the percentile).
= -(1) = -1 (When we destroy the parenthesis, if there is a minus sign outside the parenthesis, the result will become a minus.)
From the above expressions, we can see that after calculating, the second and third expressions have the same value, i. e. -1. However, the result of the first expression is different, and we get -0.6. So option one is the right choice.
It is D because all the numbers range from 12 to 23, with no number being extremely low or high compared this range.
