A patio floor is shaped like a rectangle with a
Anna007 [38]
The area of a rectangle is length x width.

Note that
1 in = 2.54 cm
1 cm = 1/2.54 = 0.3937 in 
1 cm = 0.3937/12 = 0.032808 ft
w cm = w*0.032808 = 0.032808w ft

Therefore the area of the floor is
(21 ft)*(21 cm)
= (21 ft x 0.032808w ft)
= 0.689w ft²

Answer:  0.689w ft²  (nearest hundredth)

The area of the dining room at Thomas Jefferson so I'm in Monticello is about 342 ft.² is the approximate length of one side is
Nat2105 [25]

Answer:

Yes, the approximate length of one side is a prime number less than 25.

The approximate dimensions of the room are 19 ft by 18 ft.

Step-by-step explanation:

Assuming the dining room is rectangular in shape

Approximate area of the dining room = 342 ft^2

The area of a rectangle is calculated by multiplying the length of the rectangle by the width.

Assuming the approximate length is a prime number less than 25

The closest prime number to 25 is 19

Approximate length = 19 ft

Approximate width = approximate area ÷ approximate length = 342 ft^2 ÷ 19 ft = 18 ft

Approximate dimensions of the room = 19 ft by 18 ft

Harper has $15.00 to spend at the grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers
Anestetic [448]

Answer:

Step-by-step explanation:

Let x represent the maximum number of bags of fruit that Harper can buy.

She is going to buy bags of fruit that cost $4.75 each and one box of crackers that cost $3.50. This means that the total cost of x bags of fruit and one box of crackers would be

4.75x + 3.5

If Harper has $15.00 to spend at the grocery store, it means that

4.75x + 3.5 = 15

4.75x = 15 - 3.5 = 11.5

x = 11.5/4.75

x = 2.42

Therefore, the maximum number of bags of fruit that Harper can buy is 2 because the number of bags must be whole numbers.
