Ewan is building a maze for his pet rats out of 2x4s. he needs two pieces that are 2 ¾ feet long, one that is 3.5 feet long and two that are 1 5/8 feet long. ewan can buy wood that is 84 inches long at $2.35 per board, 96 inches long that costs $3.60 for each board, or a 10 foot board, for $4.61.

2 pieces at 2 3/4 feet is 2 x 2 foot 9 inches = 5 foot 6 inches

1 piece that is 3.5 feet is 3 feet 6 inches

2 pieces that are 1 5/8 feet are 2 x 1 foot 7 1/2 inches = 3 feet 3 inches

I think there should be more to the question. If you are looking for the best combination to buy it would be two 7 foot boards

answer:

c. the third graph

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
