Answer:
The geometric mean is √(60) or about 7.75
Step-by-step explanation:
To find the geometric mean, you have to use the following equation.
GM = √(a×b)
Now we input the two numbers for a and b
GM = √(a×b)
GM = √(12×5)
GM = √(60) or about 7.75
Answer:
D. 2:20
Step-by-step explanation:
6 : 35 - 4 : 15 = 2 : 20
Answer:
(a) 180°
(b) 180°
(c) substitution property
(d) m∠3
(e) ∠3
Step-by-step explanation:
Definition: Two angles are supplementary if they add up to 180°
Proof:
By definition of supplementary angles, m∠1 + m∠2 = 180° (a) {∠1 and ∠2 are supplementary - given}
and m∠2 + m∠3 = 180° (b) {∠2 and ∠3 are supplementary - given}
Then, m∠1 + m∠2 = m∠2 + m∠3 by the substitution property (c)
Subtract m∠2 from each side. You get m∠1 = m∠3 (d)
or ∠1 ≅ ∠3 (e)
Answer: The volume of shell is 12.8π mm².
Step-by-step explanation:
Since we have given that
Radius to the inside of the shell = 4 milimeters
Radius to the outside of the shell = 4.2 milimeters
Since r changes from 4 mm to 4.2 mm
so, 
As we know that
Volume of shell is given by
So, the volume of shell is 12.8π mm².
