Suppose you are replacing the carpet in the living room where the length of the living room is five feet shorter than twice its
klasskru [66]

Answer:

$149.50

Step-by-step explanation:

Width = x

Length = 2x - 5

Perimeter of the room = 5x

Perimeter of the room = 2(length + width)

5x = 2{(2x-5) + x}

5x = 2(2x - 5 + x)

5x = 4x - 10 + 2x

5x = 6x - 10

5x - 6x = -10

-x = -10

x = 10

Width = x = 10

Length = 2x - 5

= 2*10 - 5

= 20 - 5

= 15

Perimeter of the room = 5x

= 5 × 10

= 50 square foot

If carpet costs $2.99 a square foot, what the total cost to carpet the living room

Total cost = $2.99 × 50

= $149.50

The lung capacity of the blue whale is 5100L. Convert this volume into gallons. Express your answer to two significant figures a
Vedmedyk [2.9K]
By definition, we have that the conversion of a US gallon to liters is given by:
 1 liter = 3.78541 gallons
 Therefore, we can apply the following rule of three:
 1 liter ---------------------> 3.78541 gallons
 5100 liters --------------> x
 Clearing x we have:
 x = (5100) * (3.78541)

x = 19305.591
 two significant figures:
 x = 19000

 Answer:
 
The lung capacity of the blue whale is:
 
x = 19000 gallons
