Help pls ;) <br> Find the geometric mean of 14 and 20
Kipish [7]

Answer:

The geometric mean of 14 and 20 is 16.73.

Step-by-step explanation:

It is required to find the geometric mean of 14 and 20. Let the numbers are :

a = 14 and b = 20

The geometric mean for two numbers is given by :

M=\sqrt{ab}

Plugging the values in above formula as follows :

M=\sqrt{14\times 20}\\\\M=\sqrt{7\times 2\times 5\times 4} \\\\M=16.73

So, the geometric mean of 14 and 20 is 16.73.

Which of the following BEST describes how to use the addition property of equality to isolate the variable y
Alexandra [31]

Answer:  C) add 12 to both sides

Reason:

We add 12 to the left side to undo the -12, which will get y by itself.

We must do the same thing to both sides to keep things balanced.

Please someone help me and explain this question to me (the last question starting with a straw)
Anastasy [175]

Each straw is  4-1/8 inches long.
You have one gigantic piece of straw material, 123-3/4 inches long.
How many straws can you cut it up to make ?

 ===>                    (123-3/4)  divided by  (4-1/8)            straws.

Each one costs  $0.015  to make.
So, once you find the number of short straws you have,
multiply

===>                 (the number of short straws) x ($0.015) .

That'll tell you how much it costs to make all of them. 


Now you know how to do it on your own.
If you don't get  30 straws  and  $0.45 , please try again.
