Kelly was building a bed for her dollhouse. She used her bed, which is 4 feet × 6 feet, as a guide. She scaled down the dimensions of her bed by a factor 1 over 5. What are the dimensions of the model bed she built?

A) 0.8 foot × 1.2 feet
B)0.4 foot × 0.6 foot
C)0.08 foot × 0.12 foot
)D)0.04 foot × 0.06 foot

Respuesta :

A cause 4 divide by 5 is .8 and 6 divide by 5 is 1.2
For this case we have the following dimensions:
 4 feet
 6 feet
 We multiply both dimensions by the scale factor of 1/5.
 We have then:
 (4) * (1/5) = 0.8 feet
 (6) * (1/5) = 1.2 feet
 The new dimensions are given by:
 0.8 feet x 1.2 feet
 Answer:
 
A) 0.8 foot × 1.2 feet
