Show the Euler-Descartes formula holds for the Great Pyramid of Cheops
Answer:
For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula
Step-by-step explanation:
The great pyramid of Cheops is a square based pyramid therefore we have;
V + F = E + 2
Where:
V = Vertices
F = Faces
E = Edges
Hence, we have for a square pyramid;
V = 5 vertices (One at the peak, and four at the base edges)
F = 5 faces (The four lateral or side faces and the base)
E = 8 edges ( The four lateral edges and the four base edges)
Hence;
5 + 5 = 8 + 2 which proves Euler-Descartes formula.

Answer:
11.3
Step-by-step explanation:
i used the theorem of Pythagoras
Answer:
11.3
Step-by-step explanation:
In a right angled triangle: the square of the hypotenuse is equal to
the sum of the squares of the other two sides.
[tex]8^{2} + 8^{2} = x^{2}[/tex] (x is the hypotenuse)
64 + 64 = [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 128
=> x = [tex]\sqrt{128}[/tex] = 11.3137085 = 11.3
3|2−x|=−6
can someone answer this question for me?? THNX!!!
Answer: the answer is 4
Step-by-step explanation:
3(2−x)=−6
Step 1: Simplify both sides of the equation.
3(2−x)=−6
(3)(2)+(3)(−x)=−6(Distribute)
6+−3x=−6
−3x+6=−6
Step 2: Subtract 6 from both sides.
−3x+6−6=−6−6
−3x=−12
Step 3: Divide both sides by -3.
−3x
−3
=
−12

Find the volume of a rectangular pyramid. Length measures 16 meters, width measures 24 meters, height measures 20 meters
Answer:
7680
Step-by-step explanation:
16(24)20
7680
V = 2,560 m^3
Step-by-step explanation:
The formula for the volume of a pyramid is...
[tex]V=\frac{1}{3}Bh[/tex]
B is the area of the base, which in this case is a rectangle. We need to find the area of the rectangle to plug in for B.
The formula for the area of a rectangle is...
[tex]l*w[/tex]
We can plug in the numbers.
[tex]16*24[/tex]
= 384
Now that we have B, we can plug that into the volume formula along with the height.
[tex]V=\frac{1}{3}(384*20)[/tex]
[tex]V=\frac{1}{3}*7,680[/tex]
V = 2,560 m^3

Arun’s restaurant bill is $58, and he wants to leave the waiter an 18 percent tip. What will Arun’s total bill be? $10.44 $47.56 $68.44 $76.00
Answer:
$68.44 will be the total bill.

18/100 = .18
58 x .18 = 10.44
58 + 10.44 = 68.44
:)
Answer:
It would be 68.44
Step-by-step explanation:
What you do is you multiply 58 by .18. it should come out to 10.44. Once you do that, you add the $58 dollar check with the 10.44 tip and the answer is 68.44!!
elijah's credit card statement showed these items: Last Balance Payments Finance Rate New Charges $152.58 $45.00 1.5% $213.40 What is Elijah's new balance? $320.98 $322.59 $323.27 $397.51
Answer:
Option A,$320.98 is correct
Step-by-step explanation:
The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.
last balance as shown by the statement was $152.58
new charges were $213.40
payment made by Elijah was $45
new balance=$152.58+$213.40-$45=$320.98
The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.
Answer:
Other answer is incorrect. Elijah's new balance would be $322.59

Solve the following equation:
12(b+2)+3b=−1
Enter your answer as a fraction.
Answer: -5/3
Step-by-step explanation:
12(b + 2) + 3b = -1
12b + 24 + 3b = -1
15b + 24 = -1
15b = -1-24
b = -25/15 = -5/3
The solution to the equation 12(b+2) + 3b = -1 is b = -5/3.
What is the solution to the given equation?Given the equation in the question:
12( b + 2 ) + 3b = -1
To solve the equation 12( b + 2 ) + 3b = -1, first apply the distributive property.
Distribute the 12 across the terms inside the parentheses:
12( b + 2 ) + 3b = -1
12×b + 12×2 + 3b = -1
Simplifying, we get:
12b + 24 + 3b = -1
Collect and combine the like terms on the left side of the equation:
12b + 3b + 24 = -1
15b + 24 = -1
Subtract 24 from both sides of the equation:
15b + 24 - 24 = -1 - 24
15b = -1 - 24
15b = -25
Divide both sides by 15:
b = -25/15
Simplify
b = -5/3
Therefore, the value of b is -5/3.
