konstantin123 [22]

Correct answer is A.

g - geometric mean
$g= \sqrt{ab} 
\\
\\g= \sqrt{6} ,a=4,b=?
\\ \sqrt{6}= \sqrt{4b} 
\\ (\sqrt{6})^2= (\sqrt{4b} )^2
\\6=4b
\\
\\b= \frac{6}{4} = \frac{3}{2}=1.5$

Please help 8 points each but beware if you use my points for no reason I'll report you

Answer:

V = 32

Step-by-step explanation:

Comment

I think you should try this one yourself after I post my answer. Estimation is a very valuable tool -- the more you use it, the handier it gets.

Formulas

pi = 3

V = 4/3 * pi * r^3

Givens

r = 2

pi = 3

Solution

V = 4/3 * pi * r^3 Substitute values for symbols

V = 4/3 * 3 * 2^3 Cancel the 3s

V = 4 * 2^3 Expand the 2s

V = 4 * 2 * 2 * 2 Find V

V = 32

a glacier receded 4 feet a day for a period of 25 days. how much shorter was the glacier at the end of the period.

dangina [55]

Alright, lets get started.

In the question given that glacier receded 4 feet a day for a period of 25 days.

Which shows in 1 day, it recedes = 4 feet

means in 1 day, the height of the glacier gets shorter = 4 feet

So, in 25 days, the height of the glacier gets shorter = 4 * 25

So, in 25 days, the height of the glacier gets shorter $= 100$ feet

It means the glacier will get 100 feet shorter at the end of the period of 25 days. : Answer

Hope it will help :)
