To do this, we make use of Euler's formula
[tex]F + V - E = 2[/tex]
Where
[tex]F \to Faces; V \to Vertices; E \to Edges[/tex]
[tex](a):\ Faces = 8; Vertices = 12; Edges = 6[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]8 + 12 - 6 = 2[/tex]
[tex]14 = 2[/tex]
The above equality is false. Hence, (a) does not exist
[tex](b):\ Faces = 6; Vertices = 6; Edges = 4[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]6 + 6 - 4 = 2[/tex]
[tex]8 = 2[/tex]
The above equality is false. Hence, (b) does not exist
[tex](c):\ Faces = 20; Vertices = 30; Edges = 12[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]20 + 30 - 12 = 2[/tex]
[tex]38 = 2[/tex]
The above equality is false. Hence, (c) does not exist

Hello, so the answer is 21.
Step-by-step explanation:
Okay so first we want to do it order, so the order you do it in is the order of PEMDAS which stands for Parentheses, Exponents, Multiplication, Division , Addition and Subtraction.
So in this situation we have parenthesis, multiplication, subtraction and addition, so we start with the parenthesis, (8 x 3) which is 24. So then we move on to +6 (positive six) and -9 (negative 9) basically -9 minus 6 is -3.
Sooo now we have -3 and 24. The three is negative because -9 minus 6 is -3, and you have to put the sign of the bigger number.
Now, 24 minus 3 equals 21. So there we have it :)
Hope I helped!

Step-by-step explanation:
Given data
Principal= $750
Rate= 2%
Time= 1 year
The simple interest expression is given as
A=P(1+rt)

A= 750(1+0.02*1)
A= 750(1.02)
A= $765
Hence the final amount is $765

from the house is the base of the ladder?
A. 4 feet
B. 6 feet
C. 9.06 feet
D. 4.22 feet
Answers
Answer:
Distance of ladder from base = 4.22 feet (Approx.)
Step-by-step explanation:
Given:
Length of ladder = 10 feet
Angle with ground = 65°
Find:
Distance of ladder from base
Computation:
Length of ladder (hypotenuse) = 10 feet
Distance of ladder from base (Base)
Using trigonometry function
Cosθ = Base / Hypotenuse
Cosθ = Distance of ladder from base / Length of ladder
Cos65 = Distance of ladder from base / 10
0.4226 = Distance of ladder from base / 10
Distance of ladder from base = 0.4226 x 10
Distance of ladder from base = 4.226
Distance of ladder from base = 4.22 feet (Approx.)

Santiago buys a new computer for $3000. He pays it off in 2 years and pays $480 in simple interest. What was the interest rate?
Answers
Answer:
8%
Step-by-step explanation:
We can solve this by making use of the simple interest formula
I= PRT/100
480= 3000×R×2/100
480= 6000R/100
Cross multiply
48000= 6000R
R= 48000/6000
= 8%
Hence the rate is 8%
A pack of clothes pins has 1 quarter yellow 2 thirds red and the rest blue how much blue pins are there
Answers
Answer: 1/12
Step-by-step explanation:
First make all the fractions have the same denominator. To do that, multiply the fractions by a number that will get them the same denominator. In this case, multiply 1/4 by 3, and 2/3 by 4.
1/4 x 3/3 = 3/12
2/3 x 4/4 = 8/12
then you have 3/12 + 8/12 = 11/12
so, blue is 1/12
Answer:
1/12 of the pins are blue
Step-by-step explanation:
¼ yellow & ⅔ red
First you have to find a common denominator.
4×3 =12 & 3×4 =12 so the common denominator is 12.
Now × the numerator on the fraction with the same number that you x the denominator and you will get 3/12 and 8/12.
3/12 +8/12 = 11/12
12/12 - 11/12 = 1/12
Therefor 1/12 of the pins are blue
