Answer:

666.67 ft^2

Step-by-step explanation:

We start with a 4x5 scale room

We then use the 1:20 scale to multiply the 4 and the 5 by 20

4*20=80

5*20=100

We now have the dimensions of the actual room, 80in.x100in.

Area=length*width

A=100*80

A=8000 in^2

We are not done yet, though. To get feet, you convert inches to feet. 1 foot=12 inches.

8000/12=666.667, or 666.67, or 667, depending what you would round to

Answer:

Step-by-step explanation:

L = ⁵/₂x + 10

W = ⁵/₂x + 5

A = L•W

A = (⁵/₂x + 10)(⁵/₂x + 5)

A = ⁵/₂x•⁵/₂x + ⁵/₂x•5 + 10•⁵/₂x + 10•5

A = ²⁵/₄x² + ²⁵/₂x + ⁵⁰/₂x + 50

A = ²⁵/₄x² + ⁷⁵/₂x + 50

Or if yoy mean:

L = 5/(2x) + 10

W = 5/(2x) + 5

A = [5/(2x) + 10][5/(2x) + 5] = 25/(4x²) + 75/(2x) + 50

UkoKoshka [18]

Answer:

$x = \frac{4}{9}$

Step-by-step explanation:

Given

Winning Percentage = 0.444 repeating

Required

Represent as a fraction

Represent the percentage with x

$x = 0.444$

Convert to fraction

$x = \frac{444}{1000}$

Next step, is to convert to fraction repeating

To do this, we simply subtract 1 from the denominator

$x = \frac{444}{1000 - 1}$

$x = \frac{444}{999}$

Simplify to the lowest term: Divide numerator and denominator by 37

$x = \frac{444/37}{999/37}$

$x = \frac{12}{27}$

Simplify to the lowest term: Divide numerator and denominator by 3

$x = \frac{12/3}{27/3}$

$x = \frac{4}{9}$

Hence;

There winning fraction is $\frac{4}{9}$
