1.Use Euler’s Formula to find the missing number. Edges: 40

Mathematics
1 answer:
PtichkaEL [24]3 years ago
6 0

Answer:

Euler's Formula states that:

V -E +F = 2   meaning that the vertices minus the edges plus the faces of a convex polyhedron will always equal two.

So, for the initial question, we have 40 edges and 24 faces.

So, vertices = 2 + Edges -Faces

Vertices = 2 + 40 - 24

Vertices = 18

A pigeon can fly 84 kilometers per hour. how long does the pigeon take to fly 7 kilometers?
Leviafan [203]
84 kilometers ... 1 hour
7 kilometers ... x hours = ?

If you would like to know how long does the pigeon take to fly 7 kilometers, you can calculate this using the following steps:

84 * x = 1 * 7
84 * x = 7      /84
x = 7/84
x = 1/12 hour

Result: A pigeon can fly 7 kilometers in 1/12 hour.

I need help with geometry<br> I know its not the first one
alukav5142 [94]

Answer: ASA, C

Step-by-step explanation:

I think it's ASA cuz since the lines indicate they are parallel, then you can find that the two interior angles are also congruent. Since two angles are the same with the side inbetween being the same, it's probably asa.

to find the area of a trapezoid dylan uses the formula A=1/2 (B1+B2)h the bases have lengths of 3.6 cm and 12 1/3 cm. the height
Artemon [7]

Answer:

It is irrational because it can not be represented as a fraction of two integers

Step-by-step explanation:

Given

B_1 = 3.6

B_2 = 12\frac{1}{3}

H = \sqrt[3]5

Required

Why is the area irrational?

First, we need to calculate the area

Area = \frac{1}{2}(B_1 + B_2) * H

Area = \frac{1}{2}(3.6 + 12\frac{1}{3}) * \sqrt[3]5

Area = \frac{1}{2}(3.6 + \frac{37}{3}) * 17100

Area = \frac{1}{2}(\frac{10.8+37}{3}) * 1.710

Area = \frac{1}{2}(\frac{47.8}{3}) * 1.7100

Area = \frac{47.8}{6} * 1.7100

Area = \frac{47.8* 1.7100}{6}

Area = \frac{81.738}{6}

Area = 13.623

<em>It is irrational because it can not be represented as a fraction of two integers</em>
