How many faces, vertices, and edges does a right rectangular pyramid have? 4 faces, 5 vertices, and 7 edges 5 faces, 5 vertices, and 8 edges 5 faces, 8 vertices, and 11 edges 6 faces, 8 vertices, and 12 edges
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

help me please!! I need someone to explain this for me. I need to find the area of this trapezoid!!
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! :)

Q1)
GIVEN :-
Diameter = 9m ⇒ Radius (r) = 9/2 = 4.5mSlant height (l) = 13mTO FIND :-
Surface area of the whole figure.FORMULAES TO KNOW BEFORE SOLVING :-
Curved surface area of cone = [tex]\pi rl[/tex] (where r = radius & l = slant height)Curved surface area of hemisphere = [tex]2\pi r^2[/tex] (where r = radius)PROCEDURE :-
In the figure , the cone is mounted on a hemisphere.
⇒ Radius of cone = Radius of hemisphere = 4.5m
Total surface area of the figure = Curved surface area of both cone & hemisphere.
⇒
Curved surface area of cone = [tex]\pi rl = 3.14 \times 4.5 \times 13 = 183.69m^2[/tex] ≈ 183.7m²Curved surface area of hemisphere = [tex]2\pi r^2 = 2 \times 3.14 \times (4.5)^2 = 127.17m^2[/tex] ≈ 127.1m²∴ Total surface area = 183.7 + 127.1 = 310.8m²
Q2)
GIVEN :-
Radius (r) = 3kmTO FIND :-
Volume of hemisphereSurface area of hemisphereFORMULAES TO KNOW BEFORE SOLVING :-
Volume of hemisphere = [tex]\frac{2}{3} \pi r^3[/tex] (where r = radius)Surface area of hemisphere = [tex]2\pi r^2[/tex] (where r = radius)PROCEDURE :-
Volume of hemisphere = [tex]\frac{2}{3} \pi r^3 = \frac{2}{3} \times 3.14 \times (3)^3 = 56.52km^3[/tex] ≈ 56.5km³
Surface area of hemisphere = [tex]2\pi r^2 = 2 \times 3.14 \times (3)^2 = 56.52km^2[/tex] ≈ 56.5km²

5x-3=19? Answer for Brainliest
Answer:
x = 4.4
Step-by-step explanation:
I'm going to assume you want to solve for x so here we go.
You need to work backwards for this equation, and whatever you do to the LHS, you do to the RHS.
First, you need to remove the minus 3, which means that on both sides, you add 3. Adding three on the LHS makes the -3 disappear, and adding 3 on the RHS makes the 19 go to a 22.
Your equation is now 5x=22.
Since 5x means 5 × x, to get rid of it, you need to divide 5x by 5. Doing it to the LHS will make the five disappear, and doing it to the RHS will make it go to 22 ÷ 5 which equals 4.4
Therefore, x = 4.4

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

Find the perimeter of the figure to the nearest hundredth.
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:
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:
x² + 2x - 13 = 0x² + 2x + 1 - 14 = 0(x + 1)² - 14 = 0(x + 1)² = 14x + 1 = ± √14x = -1 ± 3.74x = 2.74, x = -4.74Help please! Thanks!!!
To get this answer, we'll use the cosine ratio
cos(angle) = adjacent/hypotenuse
cos(A) = AC/AB
cos(35) = b/c
cos(35) = b/280
280*cos(35) = b
b = 280*cos(35)
b = 229.362572400918
b = 229

In 2010 a small college had an enrollment of 9500 students. The declared majors are detailed in the table below.
Step-by-step explanation:
42. 9025 (95% of 9500 or 0.95 x 9500)
43. 279 ( 279 + 861= 1140; 1140 is 12% of 9500 or 0.12 x 9500)
In a computer catalog, a computer monitor is listed as being 27 inches. This distance is
the diagonal distance across the screen. If the screen measures 15 inches in height,
what is the actual width of the screen to the nearest inch?
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
Brittney has 2 and 3/4 yards of fabric. She wants to make wreaths that require 1/8 yards. What is the maximum number of wreaths she can make?
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
What equation do I write for a line that has a y intercept of 2 and is perpendicular to y=2/3x+4?
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

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. Answer: 51.3∘ and 128.7∘ DeltaMath
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
