Jeremy built an office with a floor area of 55/14 square feet. The office is rectangular in shape. If the length of the room is 8 1/2 feet, what is the width of the room?

Answers

Answer:

110/289 feet

Step-by-step explanation:

Step one:

given data

Area of the floor= 55/14 square feet.

The length of the floor= 8 1/2 feet-----convert to simple fraction= 17/2 feet

Step two:

The expression for the area of the room is

Area= L*W

55/14= 17/2*W

55/14=17W/2

cross multiply

17W*14=55*2

289W=110

divide both sides by 289

W= 110/289 feet

Julio considers the reduction of the triangle. What is the correct cross product that he should use to solve for the missing dimension? (8)(12) = 21x (8)(21) = 12x (12)(8) = 12x (12)(21) = 8x

Answers

Answer:

(8)(21) = 12x

Step-by-step explanation:

(8)(12) = 21x

(8)(21) = 12x

(12)(8) = 12x

(12)(21) = 8x

Opposite : Adjacent

12 in : 21 in

Opposite : Adjacent

8 in : x in

Equate both ratios to solve for x

12 : 21 = 8 : x

12 / 21 = 8 / x

Cross product

(12)(x) = (21)(8)

12x = 168

x = 168 / 12

= 14

x = 14
