Wall to wall, means area of the floor
408=carpet+instalation
408=carpet+120
minus 120 both sides
288=carpet
12 per square foot
288=12x
divide both sides by 12
24=x
she bought 24 square yards
D is answer
The distance traveled to the top of the escalator to the bottom is 52 ft
Here, we want to calculate the distance a person on the escalator travel from the bottom to the top of the escalator
Firstly, we need a diagrammatic representation to understand this
We can form a right-angled triangle with the information given in the question.
The diagram is shown as below;
From the question, by simply calculating the hypotenuse of the right-angled triangle, we can get the distance traveled from the bottom of the escalator to the top
Let us call this distance d
We can now use the appropriate trigonometric ratio
The trigonometric ratio to use here is the sine since we have the opposite and we want to calculate the hypotenuse
Mathematically;
ANSWER: x= 3/11
EXPLANATION:
5/6x-1/10x=2/15
= (25x-3x)/30=3/15 (FINDING COMMON DENOMINATORS)
= 22x/30=2/15
= 11x/15=2/15 (SIMPLIFYING THE NUMBERS)
= x=2/15*15/11 (MOVING THE NUMBERS) (11/15 will be 15/11 when it is moved to the other side)
= x=30/165
= x= 2/11 (SIMPLIFYING)
Hope it helps!
