Stan has a rectangular piece of carpet with an area of 23.4 square meters. The piece of carpet is 13 meters long. What is the width of the piece of carpet?

Answers

Answer:

The breadth of rectangular carpet is 1.8 m.

Step-by-step explanation:

We have,

The area of rectangular carpet that is 23.4 m²The length of carpet is 13 m.

We know that,

= Area of rectangle = Length × Breadth

= 23.4 = 13 × Breadth

= 23.4/13 = Breadth

= 234/130 = Breadth

= 1.8 m = Breadth

A rectangular prism and it’s dimensions are shown in the diagram. What is the total surface are of the rectangular prism in square feet?

Answers

Answer:78.5

Step-by-step explanation:

The total surface area of the rectangular prism shown is 78.5 feet².

What is Rectangular Prism?

Rectangular prism is a three dimensional shape which consist of six faces. The two faces are at the top and bottom and the other faces are lateral faces.

The surface area of a rectangular prism can be calculated as,

Surface area = 2 (lw + wh + lh)

Here l is the length, w is the width and h is the height of the rectangle.

From the figure,

l = 4.5 feet

w = 4 feet

h = 2.5 feet

Surface area = 2 [ (4.5 × 4) + (4 × 2.5) + (4.5 × 2.5)]

                     = 2 [18 + 10 + 11.25]

                     = 2 × 39.25

                     = 78.5 feet²

Hence the surface area is 78.5 feet².

A 16-oz package of rice is $0.79. A 32-oz package is $3.49. Which has the lower unit cost?
Group of answer choices

Answers

16 ounce bag of rice for $0.04 per unit
16 oz. : $0.79

1 oz. : 0.79/16 = $0.049375

Round to three decimal places

Unit cost = $0.049



32 oz : $3.49

1 oz : 3.49/32 = $0.1090625

Round to three decimal places

Unit cost = $0.109



0.109 > 0.049


Answer: 16 oz. pack has a lower unit cost.

If the area of a sector is 100 ft^2 and the radius of the circle is 22 ft what is the central angle measure for that sector and what is the length of the arc

Answers

Answer:

[tex]\displaystyle \theta=0.413\ rad[/tex]

L= 9.086 feet

Step-by-step explanation:

Area of a Circular Sector

Given a circle of radius r, the area of a circular sector defined by a central angle θ (in radians) is given by

[tex]\displaystyle A=\frac{1}{2}r^2\theta[/tex]

And the length of the arc is:

[tex]L=\theta r[/tex]

We know the area of the sector is 100 square feet and the radius is r=33 ft, thus:

[tex]\displaystyle 100=\frac{1}{2}r^2\theta[/tex]

Solving for θ:

[tex]\displaystyle \theta=\frac{200}{r^2}[/tex]

[tex]\displaystyle \theta=\frac{200}{22^2}[/tex]

[tex]\displaystyle \theta=0.413\ rad[/tex]

The arc length is:

[tex]L=0.413* 22[/tex]

L= 9.086 feet

Answer:

[tex] A(\triangle ABC) = 7.2\: units^2 [/tex]

Step-by-step explanation:

C = (0, 7)

Since, point A lies on y-axis, so it's x coordinate will be zero. Line y = 2x + 1 passes through point A.

Therefore, plug x = 0 in y = 2x +1, we find:

y = 2*0 + 1 = 0 + 1 = 1

Hence, coordinates of point A are (0, 1).

Now, by distance formula:

[tex] AC= \sqrt{(0-0)^2 +(7-1)^2} [/tex]

[tex] AC= \sqrt{(0)^2 +(6)^2 }[/tex]

[tex] AC= \sqrt{0 +36 }[/tex]

[tex] AC= \sqrt{36 }[/tex]

[tex] AC= 6\: units[/tex]

Length of perpendicular CB dropped from point C (0, 7) to line y = 2x + 1 or 2x - y + 1 = 0 can be obtained as given below:

[tex] CB =\frac{|2\times 0+(-1)\times 7+1|}{\sqrt {2^2 +(-1)^2} } [/tex]

[tex] CB =\frac{|0-7+1|}{\sqrt {4 +1} } [/tex]

[tex] CB =\frac{|-6|}{\sqrt {5} } [/tex]

[tex] CB =\frac{6}{2.24} [/tex]

[tex] CB =2.68\: units [/tex]

By Pythagoras Theorem:

[tex] AB=\sqrt{AC^2 - CB^2} [/tex]

[tex] AB=\sqrt{6^2 - (2.68)^2} [/tex]

[tex] AB=\sqrt{36 - 7.18} [/tex]

[tex] AB=\sqrt{28.82} [/tex]

[tex] AB=5.36842621\: units [/tex]

[tex] AB\approx 5.37\: units [/tex]

[tex] A(\triangle ABC) = \frac{1}{2} \times AB\times CB[/tex]

[tex] A(\triangle ABC) = \frac{1}{2} \times 5.37\times 2.68[/tex]

[tex] A(\triangle ABC) = \frac{1}{2} \times 14.3916[/tex]

[tex] A(\triangle ABC) = 7.1958[/tex]

[tex] A(\triangle ABC) = 7.2\: units^2 [/tex]

[tex]A=p^2-2p-3[/tex]

Step-by-step explanation:

The area for a triangle is given by:

[tex]\displaystyle A=\frac{1}{2}bh[/tex]

The base is p + 1 and the height is 2p - 6. Therefore:

[tex]\displaystyle A=\frac{1}{2}(p+1)(2p-6)[/tex]

Simplify the second term:

[tex]\displaystyle A=(p+1)(\frac{1}{2})(2p-6)=(p+1)(p-3)[/tex]

Distribute:

[tex]A=p(p-3)+1(p-3)[/tex]

Distribute:

[tex]A=p^2-3p+p-3[/tex]

Combine like terms:

[tex]A=p^2-2p-3[/tex]
