The circumference of the inner circle is 44 ft. The distance between the inner circle and the outer circle is 3 ft. By how many
Citrus2011 [14]

Answer: 18.86 feet

Step-by-step explanation:

The formula for determining the circumference of a circle is expressed as

Circumference = πD

Where D represents the diameter of the circle.

The circumference of the inner circle is 44 ft. It means that

22/7 × D = 44

22D = 7 × 44 = 308

D = 308/22

D = 14 ft

The distance between the inner circle and the outer circle is 3 ft. This means that the diameter of the outer circle would be

14 + 3 + 3 = 20 ft

Circumference of the outer circle is

22/7 × 20 = 62.86 ft

The number of feet by which the circumference of outer circle is greater than the circumference of the inner circle is

62.86 - 44 = 18.86 feet

X=(y)/(y-3) make y the subject
Liula [17]

Answer:

\displaystyle y=\frac{3x}{x-1}

Step-by-step explanation:

<u>Solving Equations</u>

We have the expression:

\displaystyle x=\frac{y}{y-3}

And it's required to make y the subject.

It can be done by isolating y on the left side of the equation and the rest of the expression on the right side.

The first step is removing the denominator by multiplying both sides by y-3:

\displaystyle (y-3)x=(y-3)\frac{y}{y-3}

Simplifying the right side:

\displaystyle (y-3)x=y

Remove the parentheses:

yx-3x=y

Move the y's to the left side and the rest of the expression to the right side:

yx-y=3x

Factor out y:

y(x-1)=3x

Divide by x-1:

\mathbf{\displaystyle y=\frac{3x}{x-1}}
