The geometric mean of two numbers x and y is √(xy).
So, if the geometric mean of 3 and a is 9 =>
9 = √(3a)
=> 9^2 = 3a
=> a = 9^2 / 3
a = 81 / 3
a = 27
Answer: the value of a is 27.
Answer:
$23.41
Step-by-step explanation:
Add the cost of each item together.
$9.95 + $13.46 = $23.41
And there may have been sales tax as well but this information was not provided so it is not needed in the answer.
Answer:
my answer for y is -6, x is -10
Step-by-step explanation:
just eliminate the -4s by subtracting them and you will get the value of y.
now you can use either eqn (I) or (ii) which are first and second.
anyone you decide to choose just replace y by the value you got and you will get the value of x.
pls try to do it buddy you can
Answer:
Addition: -1 + -3 = -4
Subtraction: (-4) - 5 = -10
Step-by-step explanation:
Since adding a positive makes a negative number stay negative, it equals -4.
Then by subtracting a negative with a positive (5), the number stays negative once again, which then equals -10.
The exterior angles of a polygon all add to 360, if you need to find an exterior angle when given the number of sides and that all angles are equal you simply do: 360/ number of sides.
When you need to find the exterior angle when given an interior angle, you do: 180- interior angle.
Hope this helps :)
