Answer:
Diameter = 23 Radius = 11.5
Step-by-step explanation:
Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.
<em>72.22 ÷ 3.24 = 23</em>
diameter = 23
Divide the diameter by 2.
<em>23 ÷ 2 = 11.5</em>
There you go, you found the circle's radius
Step-by-step explanation:
x2 + 7x + 12
x2 + 4x + 3x + 12
x(x + 4) + 3( x + 4)
(x + 3) and (x + 4) are the factors
4x2 + 6x + 2
4x2 + 4x + 2x + 2
4x (x + 1) + 2(x + 1)
(x + 1) and (4x + 2) are the factors
D = m/v
V = 2•2•2 = 8cm^3
D = 12/8 = 1.5g/cm^3
Answer is B
Answer:
680
Step-by-step explanation:
Use the binomial coefficient where you choose 
numbers out of 
possible numbers and find the total amount of combinations since order does not matter:
Thus, you can make 680 three-non-repeating-number codes
