rosijanka [135]

Answer:

8 -7/16 y+4/5 p - 3/8 y

-7/16 y -3/8 y expand fraction so it would turn to

-7y/16-3y/8

multiply by 2 on the 3/8 to get a common demominator

-7y/16-6y/16

-7y-6y/16

collect like terms

-13y/16

rewrite fraction

- 13/16y

so the whole equation would turn into

8-13/16y+4/5p

A ladder reaches 2m up a wall. The foot of ladder is 0.4m from the wall. For safety reasons, the slope should be between 6.3 and

NeTakaya

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

According to question

slope of the ladder = $\dfrac{\textrm height of ladder up wall}{\textrm distance of base of ladder from wall}$

Or, x = $\dfrac{2 meters}{0.4 meters}$

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
