Use this fact to show that 0.077777...=7/90

Answers

Step-by-step explanation:

Here we have , 0.7777…=7/9 . And using this fact we need to find show that

0.077777...=7/90 . Let's show this:

In the equation $0.077777...=7/90$ , Let's evaluate RHS :

⇒ $0.077777$

⇒ $(0.77777)/(10)$

But According to question , 0.7777…=7/9 , So

⇒ $(0.77777)/(10)$

⇒ $((7)/(9))/(10)$

⇒ $(7)/(9) ((1)/(10) )$

⇒ $(7)/(90)$

Since , RHS=LHS . Therefore, $0.077777...=7/90$ is proved using fact 0.7777…=7/9 .

Room is 360 square feet. The width is 5/8 the length. What is the length

Answers

Since you are given the width of 5/8 of the length, I will assume thatthe figure is a rectangle. Let us represent W as the width and L as the length.So we have W = 5/8L. then we are also given the area of the rectangle at 360square feet. The area of the rectangle is represented by the formula A = LxW.

A = LxW
360 square feet = L(5/8L)
L^2 = 576 square feet
L = 24 feet
