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!!
We can automatically see that we are dealing with a percent decrease because we are going from a smaller to a bigger number. We need to first find what percent of 140the number 84 is. to do this we can set up the following equation:
140/84=100/x (this equation is basically saying if 140 is 100(%) what would 84 be?)
solving for x here gives us x = (84 X 100)/140 = 60, so 84 is 60 percent of 140 which means 140 decreased by 40 percent.
Let me know if I can clear anything else up.
Answer:
120 with 2 left over
Step-by-step explanation:
482/4 equals 120.5 so each basket gets 120 and then .5+.5+.5+.5= 2 whole extra apples
Answer:
The hourly wage of Ms. Franco is $28.38 .
Option (B) is correct .
Step-by-step explanation:
As given
Ms. Franco earned $709.54 in net pay for working 25 hours.
Thus
Putting values in the above
Hourly wage = $ 28.38
Therefore the hourly wage of Ms. Franco is $28.38 .
Option (B) is correct .
Root root 20^2 - 4^2
X = 2
