Perimeter of rug = 42 feet
Lengths are same in square and rectangle shapes; therefore;
Length of rug = 12 feet
Width of rug = w
Perimeter = Length + Length + Width + Width
Perimeter =
Dividing both sides by 2
The width of the rug is 9 feet.

Answer:
y = x - 4
Step-by-step explanation:
The line passes through (-1,-5) and (-3,-7)
The slope of a line is given by; change in y ÷ change in x
i.e slope = =
= 1
Taking another point (x,y) on the line.
Slope will be; = 1
Cross multiplying gives; y + 5 = x + 1
Simplifying this equation gives us the equation of our line which is;
y = x - 4
Answer:
Rocket can hold maximum 4.5 gallons of water.
Step-by-step explanation:
Volume of the rocket = Volume of the cone on the top + Volume of the cylinder at the bottom
Volume of the cone =
Here r = radius of the circular base
h = height of the cone
Volume =
= cubic inch
Volume of the cylinder =
Here r = radius of the base
h = height of the cylinder
Volume =
= 256π cubic inches
Volume of the rocket =
=
= 1038.82 cubic inches
Since 231 cubic inches volume of a rocket can hold water = 1 gallon
Therefore, 1038.82 cubic inches space can hold water
=
= 4.497
≈ 4.5 gallons
Rocket can hold 4.5 gallons of water.
