Mr. Hamilton decorates his U. S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 3/4 feet long. Each president picture is 6 feet inches wide.

8 pictures

Step-by-step explanation:

Wall length = 9.75 ft

Window length = 5.75 ft

Length of wall available for pictures:

9.75 ft - 5.75 ft = 4 ft

1 ft = 12 in

4 × 12 in = 48 in

Each picture is 6 in wide.

48 in / 6 in = 8

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
