1.5(0.13) + 3.4(0.21) =
0.195 + 0.714 =
0.909 rounds to 0.91 <== he paid 91 cents
In the scale the bedroom's size would be 10 cm long and 6 cm wide, and the door's width would be 1.6 cm. In turn, the real bed size is 2m by 1.5 m.
Since Elena wants to make a scale drawing of her bedroom, and her bedroom is a rectangle with length 5 m and width 3 m, and Elena's bedroom door is 0.8 m wide, and Elena's bed measures 4 cm and cm on the scale drawing, If the scale is from 1 to 50, to determine the dimensions of the bedroom and door scale, and the actual dimension of the bed, the following cross multiplication calculations must be performed:
- Room size = 10 cm long and 6 cm wide
- 50 = 5
- 1 = X
- 5/50 = X
- 0.1 = X
- 0.1m = 10cm
-
50 = 3
- 1 = X
- 3/50 = X
- 0.06 = X
- 0.06m = 6cm
- Door width = 1.6 cm
- 50 = 0.8
- 1 = X
- 0.8 / 50 = X
- 0.016 = X
- 0.016m = 1.6cm
- Bed size = 2m by 1.5m
- 1 = 4
- 50 = X
- 50 x 4 = X
- 200 = X
- 200 cm = 2 m
- 1 = 3
- 50 = X
- 50 x 3 = X
- 150 = X
- 150cm = 1.5m
Therefore, in the scale the bedroom's size would be 10 cm long and 6 cm wide, and the door's width would be 1.6 cm. In turn, the real bed size is 2m by 1.5 m.
