A) dilation, because size is changed by a factor/ratio
Hey there,
Each cake recipe would call for

cup of oil.
So if she is going to make 12 cakes, this would include that she
would need to use 12 cups of oil.

would be your answer!
Hope this helps.

There are 105 in 6th grade because there are 75 boys right? So it said the ratio of girls is 7 and the ratio of boys is 5 so I divided 75 to 5 = 15 and I multiply 7 to 15 and got 105 girls.
Since these are supplementary angles (two angles which sum to 180°) we can say:
4x+x=180 combine like terms on left side
5x=180 divide both sides by 5
x=36°
