Step-by-step explanation:
part A:
ABCD is transformed to obtain figure A′B′C′D′:
1) by reflection over x-axis, obtain the image :
A(-4,-4) B(-2,-2) C(-2, 1) D(-4, -1)
2) by translation T (7 0), obtain the image :
A'(3,-4) B'(5,-2) C'(5, 1) D'(3, -1)
part B:
the two figures are congruent.
the figures that transformed by reflection either or translation will obtain the images with the same shape and size (congruent)
Answer:
6.75 grams
Step-by-step explanation:
Total amount of lemonade with Samantha = 4 1/2 gallons
= (4*2 + 1)/2 gallons = 9/2 gallons = 4.5 gallons
Amount of fat in 1 gallon of lemonade = 1.5 grams
To find amount of fat in 4.5 gallons lemonade
we multiply both side of equation with 4.5
Amount of fat in 1*4.5 gallon of lemonade = 1.5*4.5 grams = 6.75 grams
Thus,
there is 6.75 grams of fat in all the lemonade Samantha has for the party
