What is the geometric mean between 6 and 12?

The geometric mean is the product of all the numbers in a set, with the root of how many numbers there are.
here, there are two numbers, so a square root is used.
geometric mean of
3
and
12
:
√
3
⋅
12
3
⋅
12
=
36
√
36
=
6
the value of the geometric mean of
3
and
12
is
6
.

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
