1/8 +c= 4/5 what does c equal ​
Ray Of Light [21]

Answer:

c=27/40 = 0.675

Step-by-step explanation:

the statement give us the expression:

1/8 +c= 4/5

we subtract the term "1/8" both sides:

we have:

1/8 -1/8+c= 4/5-1/8

c=4/5-1/8

c=(4*8)-(5*1)/(5*8)

c=(32-5)/(40)

c =27/40 = 0.675

a whisper volume as a room that allows two people to stand on opposite side of the template luckily shape long and hear each oth
Yakvenalex [24]

Answer:  120 ft

<u>Step-by-step explanation:</u>

The Ellipse equation is:   \dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1       where

  • (h, k) is the center
  • "a" is the horizontal radius
  • "b" is the vertical radius
  • c is the distance from the center to the foci: |a² - b²| = c²

Given: horizontal diameter = 122  →  horizontal radius = 61 = a

          vertical diameter = 22  →  vertical radius = 11 = b

Foci (c):   61² - 11² = c²

            3721 - 121 = c²

                  3600 = c²

                    ±60 = c

Let (h, k) = (0, 0)

Then the foci are located at -60 and +60.

The distance between them is 60 + 60 = 120
