Use Euler’s formula to find the number of vertices in a polyhedron with 6 square faces and 12 edges

Sloan [31]

Answer:

$V = 8$

Step-by-step explanation:

we know that

The Euler's formula state that: In a polyhedron, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

$V - E + F = 2$

in this problem we have

$V=?\\E=12\\F=6$

substitute the given values

$V - 12 + 6 = 2$

solve for V

Combine like terms left side

$V - 6 = 2$

Adds 6 both sides

$V - 6+6 = 2+6$

$V = 8$

Pablo has to paint $\frac{1}{3}$ more murals.
Painted mural to jar of paint ratio: $\frac{2}{3} paintedmurals: \frac{4}{5} jarofpaint$
Simplify the ratio.
$\frac{1}{3} paintedmurals: \frac{2}{5} jarsofpaintused$
Pablo needs 2/5 jars of paint per each 1/3 painted murals
$3*\frac{2}{5}$
$\frac{6}{5}$

Paige earned $15.50 per hour. She received an 18% raise. If Paige worked 10 hours at her new salary. How much did Paige earn?

BaLLatris [955]

First, figure out the new salary. To do this, multiply 15.50 and 0.18. This is 2.79. Add this to 15.50.

15.50 + 2.79=18.29

Therefore, $18.29 is her hourly pay.

To find how much money she earns in 10 hours, multiply this pay per hour (18.29) times the hours worked (10).

18.29 x 10

182.9

This means that Paige earns $182.90 for working 10 hours.

Hope this helps! Please comment if you need any more explanation and I’ll get back to you ASAP :)
