The correct answer is B. because 45 + 72 does not equal 9(5+9)

45 + 72 = 117 does not equal 9(5+9) = 126.

How many edges does a polyhedron with 28 faces and 40 vertices have calculator?

emmasim [6.3K]

Hey user!

your answer is here..

we know about EULER'S FORMULA, it is a formula used to verify a polyhedron or to calculate the number of faces, vertices or edges.

Euler's formula = F + V - E = 2

given :-

faces = 28, verticies = 50 and edge = ?

we know that F + V - E = 2

therefore 28 + 40 - E = 2

==> 68 - E = 2

==> - E = 2 - 68

==> - E = - 66

==> E = 66

hence, the number of edges of the polyhedron is 66.

cheers!!

How do you do the second part of the problem?

Sveta_85 [38]

Answer:

Step-by-step explanation:

According to the Alternating Series Estimation Theorem:

│aₙ₊₁│≤ ε

1 / (4 (n + 1)⁴) ≤ 0.00005

4 (n + 1)⁴ ≥ 20000

(n + 1)⁴ ≥ 5000

n + 1 ≥ 8.41

n ≥ 7.41

n must be an integer, so n ≥ 8.

Graph the image of the given triangle under a dilation with a scale factor of 1/4 and center of dilation (0, 0)

schepotkina [342]

Answer:

The image in the attached figure

Step-by-step explanation:

we know that

The dimensions of the image of the given triangle are equal to the original dimensions of the pre-image multiplied by the scale factor

In this problem the scale factor is 1/4

The height of the pre-image is 4 units

The base of the pre-image is 8 units

Find out the dimensions of the image

The height of the image is $(4)\frac{1}{4}=1\ unit$

The base of the image is $(8)\frac{1}{4}=2\ units$

The image in the attached figure

A 12 inch candle and an 18 inch Candle are lit at 6 p.m. The 12 inch candle burns 0.5 inches every hour. The 18 inch candle burn

Stella [2.4K]

18 - 2H = 12 - .5H
Combine the variables
18 - 2H + .5H = 12 - .5H + .5H
18 - 1.5H = 12
Combine the whole numbers
18 - 18 - 1.5H = 12 - 18
-1.5H = -6
Divide by -1.5
-1.5H/-1.5 = -6 / -1.5
H = 4
The answer is 4 hours
