Which composition of transformations will create a pair of similar, not congruent triangles? a rotation, then a reflection
a translation, then a rotation
a reflection, then a translation
a rotation, then a dilation

D  a rotation, then a dilation

Step-by-step explanation:

A triangle is said to be congruent when all angles are equal to each other and and has the same side.

it is similar  when the two angles correspond with each other and has different sides.

so for a triangle to be different in side only a dilation has to be apply to it. Performing a rotation,reflection, and translation doesn't change the size of the shape it  changes the position of the shape.  

the ratio of grapes to blueberries she should use is 12: 3

step-by-step explanation:

if mandie is making 15 cups of fruit salad, the ratio of grapes to blueberries she should use is 12: 3.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
