She can make 6 pies.
Subtract 9-1.5=7.5
then 7.5/1.25= 6.04
That's a Congruent Triangle question.
The first thing that we should to analize is it: What figure is EFGH? The question say for us that
and
, therefore, EFGH is a parallelogram because its parallel sides are congruents (equals).
Now, we should to proof that
. The simbol "≅" means congruence, that is,
means that the triangles EFH and GHF are equals.
Let's proof:
is a diagonal of the parallelogram EFGH. When we have a diagonal in a parallelogram, the opposite angles are congruents (look at the picture: the blue angles are congruent and the red angles are congruents too). Therefore,
and
.
Both triangle has a comum side: the diagonal
. The diagonal
is between two angles that we know that are congruents, Therefore, by the case ASA (Angle, Side, Angle), we proof that
.
Decrease = New number - Original Number
% Decrease =

× 100
Decrease = 9 - 12 = -3
% Decrease =

= -0.25 × 100 = -25
Your answer =
-25
