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!!

Which expression is equivalent to 2x2 + (4x - 6x2) + 9 - (6x + 3)?

Troyanec [42]

Answer:

-4 $x^2$ -10x+6

Step-by-step explanation:

I am going to assume the (Something)x2 means (Something) $x^2$ . Then, the expression is 2 $x^2$ -6 $x^2\\$ +4x-6x+9-3=-4 $x^2$ -10x+6

17. Two tanks are similar in shape. The capacity of the tanks are 1,000,000 litres and 512, 000 liters respectively

Gnesinka [82]

Given that, Two tanks are similar in shape. The capacity of the tanks are 1,000,000 litres and 512, 000 liters respectively.Find the height of the smallest tank if the larger is 300cm tall?

Assume that, the tanks are rectangular in shapes and differ only on their heights. The volume of the larger tank is

V1 = l × w × h1 while the volume of the smaller tank is V2 = l ×w × h2. The ratios of the capacities is

$\sf \frac{V1}{V2} = l \times w \times h1 \times w \times h2 = \frac{h1}{h2}$

Solving for the height of the smaller tank h2

$\sf \frac{V1}{V2} = \frac{h1}{h2}$

$\sf\frac{1000000} {51200} = \frac{ 300 cm }{ h2}$

1000000 × h2 = 51200 × 300 cm

h2 = (51200 × 300 cm) /1000000

h2 = 15.36 cm

$\sf\implies \: \boxed{ \bf{ \: Height \: of \: the \: smaller \: tank \: is \: 15.36 cm.\: }}$

${ \underline {\rule{5000pt}{6pt}}}$
