Answer:

Rectangular pyramid : Faces, Vertices, Edges = 5 , 5 , 8 respectively

Step-by-step explanation:

Rectangular pyramid is a 3D shape, with base as rectangle & triangle face corresponding to each side of base (on the top)

Faces = 5 { 1 rectangular base face , 4 triangular faces above}

Vertices = 5 { 4 vertices of rectangle, 1 vertice on top - where triangles' tips intersect}

Edges = 8 {4 edges of rectangle at base , 4 edges of triangles above}

Answer:

b. 5, 5, 8

Answer:

61.68cm

Step-by-step explanation:

Perimeter of the semicircle = 2πr

r is the radius = 12/2 = 6cm

Perimeter of the semi circle = 2(3.14)(6)

Perimeter of the semi circle = 37.68cm

Adding the remaining sides of the polygon

Perimeter of the figure = 37.68+ 10 + 6 + 8

Perimeter of the figure = 61.68cm

Hence the perimeter of the figure is 61.68cm

Answer:

The actual width of the screen = 22.45 inches

Step-by-step explanation:

From the above question, we are given the following parameters

Diagonal = 27 inches

Height (Length) = 15 inches

Width = ???

To solve this question we would be using Pythagoras Theorem.

Diagonal² = Length² + Width²

Width² = Diagonal² - Length²

Width = √Diagonal² - Length²

Width = √27² - 15²

Width = √729 - 225

Width = √(504)

Width = 22.449944321 inches

Approximately to the nearest inch,

The actual width of the screen = 22.45 inches

Answer:

the total of angle's in traingle is 180

so 85+53+c=180

c=180-138

c=42

Step-by-step explanation:

180° = m∠A + m∠B + m∠C

180° = 85° + 53° + m∠C

180° = 138° + m∠C

m∠C = 180° - 138°

= 42°

Step-by-step explanation:

change the angle to radian

then use formula 1/2 × π × radius square

Answer:

Step-by-step explanation:

Complete the square

[tex]x^{2}[/tex] + 2x - 13 = 0

[tex]x^{2}[/tex] + 2x        = 13

[tex]x^{2}[/tex] + 2x + [tex]1^{2}[/tex] = 13 +1 (take 1/2 of the b term , the 2 )

[tex]x^{2}[/tex] + 2x + 1 = 14

(x +1)^2 = 14

Answer:

Complete the square:

Answer:

166mm

Step-by-step explanation:

i am smart

Answer:

146 mm²

Step-by-step explanation:

First, let's start with the formula for the surface area of a rectangular prism.

A = 2(wl + hl + hw)

Plug in everything that you know.

A = 2[(4 · 5) + (7 · 5) + (7 · 4)]

Simply the equation.

A = 2(20 + 35 + 28)

A = 2(73)

A = 146

Answer:

78 feet

Step-by-step explanation:

6/36=13/x

6×x=13×36

6x=468

6x/6=486/6

x=78

Answer:

The answer is 50.

Step-by-step explanation:

A=(a+b)/2 x h is the formula you would use to find the area of a trapezoid.

So, (9+11)/2 times 5 would be 50.

I hope this helps you! :)

Answer:

Answer: 51.3∘ and 128.7∘

Step-by-step explanation:

In ΔUVW, w = 5.3 inches, v = 3.6 inches and ∠V=32°. Find all possible values of ∠W, to the nearest 10th of a degree.

We solve the above question using sine rule formula. This is given as:

w/sin W = v/sin V

w = 5.3 inches

v = 3.6 inches

∠V=32°.

5.3/sin W = 3.6/sin 32

Cross Multiply

sin W × 3.6 = 5.5 × sin 32

sin W = 5.5 × sin 32/3.6

W = arc sin (5.5 × sin 32/3.6)

W = 51.28° or 128.72°

Approximately

= 51.3° or 128.7°

Answer:

128.7

Step-by-step explanation:

Answer: 22

Step-by-step explanation:

Given

Brittney has 2 and  [tex]\frac{3}{4}[/tex] yards of fabric

Converting it to a fraction

[tex]\Rightarrow 2\ \dfrac{3}{4}=\dfrac{8+3}{4}\\\\\Rightarrow \dfrac{11}{4}[/tex]

Wreath require [tex]\frac{1}{8}[/tex] yards

Number of wreaths that can be made

[tex]\Rightarrow n=\dfrac{\frac{11}{4}}{\frac{1}{8}}\\\\\Rightarrow n=\dfrac{11}{4}\times \dfrac{8}{1}\\\\\Rightarrow n=22[/tex]

She can make 22 wreaths

Answer:

The correct answer is [tex]108\pi (yd^3)[/tex].

Step-by-step explanation:

The formula to find a volume of a cone is [tex]\pi r^2*\frac{h}{3}[/tex], where [tex]r[/tex] represents the radius and [tex]h[/tex] represents the height of the cone. By substituting the values in, you'll get that the volume of the cone is equivalent to [tex]\pi*6^2*\frac{9}{3}[/tex] = [tex]36\pi * 3[/tex] = [tex]108\pi (yd^3)[/tex], so that is the answer.

Answer:

108 cu. yd.

Step-by-step explanation:

V = [tex]\frac{\pi r^{2} h}{3}[/tex] = [tex]\frac{ \pi 6^{2} *9}{3}[/tex] = [tex]\frac{36(9)\pi }{3}[/tex] =[tex]\frac{ 324\pi }{3}[/tex] =  108 cu. yd.

Answer:

y = -3/2x + 2

Step-by-step explanation:

The equation has the format  y = mx + b  where  m  is the slope and  b  is the y-intercept.

The question gives you the y-intercept, so  b = 2.

As for the slope, you need the fact that perpendicular lines have slopes that are opposite ("negative") reciprocals of each other.

The slope of the line given in the question is 2/3.  The opposite reciprocal of 2/3  is  - 3/2.

The equation for the line is  y = -3/2x + 2

Answer:

A: Isosceles B: Scalene C: Isosceles, Equilateral D: Scalene

Step-by-step explanation:

A: 2 angles are equal so the sides are (Isosceles)

B: None of the sides are equal (Scalene)

C: All the sides are equal (Isosceles & Equilateral)

D: None of the angles are equal, so none of the sides are (Scalene)

Step-by-step explanation:

2.25x has an infinite number of equivalents.

Three are as follows:  (225/100)x, (9/4)x and (0.00225/0.001)x

Answer:

x = 6

Step-by-step explanation:

-3.5x + 8.5x - 4 = 26

-3.5 + 8.5x = 26 + 4

5.0x = 30

x = 30/5

x = 6

Answer:

x=6

Step-by-step explanation:

First, add -3.5x and 8.5x to combine like terms, which would then look like 5x-4=26.

Next, add 4 to both sides of the equation, which would then be 5x=30.

Finally, divide both sides of the equation by 5 and then simplify.

The final answer would be x=6.
