1 answer:
11 kilograms of the same dog food costs $69.85.
Step-by-step explanation:
Step 1:
Paris buys 18 kg of dog food for $114.30. The food can be purchased in 1 kg bags.
If she bought the 18 kg of dog food with 1 kg bags, she would have had to buy 18 such bags.
So we need to calculate the cost of a 1 kg bag.
If 18 bags cost $114.30 we divide it by 18 to calculate the cost of 1kg.
The cost of a 1 kg bad
So a 1 kg bag of dog food costs $6.35.
Step 2:
To calculate the cost of 11 kg of the same dog food, we multiply the cost of a single bag with the number of bags.
If she were to buy the 11 kg through 1 kg bags, she would need to buy 11 such bags.
The cost of 11 kg of dog food
So 11 kg of dog food would cost $69.85.

Answer:
Option (2). 1
Step-by-step explanation:
Coordinates of point A, B, C and D are,
A(-4, 4), B(-2, 4), C(-2, 1) and D(-4, 3).
Quadrilateral ABCD when rotated 90° clockwise about the origin,
Rule for the rotation of the vertices,
(x, y) → (y, -x)
Following the rule of rotation coordinates of the image points,
A(-4, 4) → A'(4, 4)
B(-2, 4) → B'(4, 2)
C(-2, 1) → C'(1, 2)
D(-4, 3) → D'(3, 4)
Since all image points have the positive coordinates (x and y coordinates), image quadrilateral A'B'C'D' will be located in 1st quadrant.
Option (2) is the correct option.
