Ms.Lopez has created a floor plan of a dollhouse. The area of the entire dollhouse is 576 square inches
1 answer:
Answer:
(a)Area of the bedroom=96 square inches
(b)Area of the living room =144 square inches
(c)Area of the dollhouse that is not of the bedroom or living room =336 square inches.
Step-by-step explanation:
The area of the bedroom is 1/6 the area of the entire dollhouse
The area of the living room is 3/2 times the area of the bedroom.
The area of the entire dollhouse is 576 square inches
Let the area of bedroom=b
Let the area of living room=l
(a) The area of the bedroom is 1/6 the area of the entire dollhouse
square inches
(b)The area, in square inches, of the living room
The area of the living room is 3/2 times the area of the bedroom
l= square inches
(c)The total area of the house =576 square inches
Area of the bedroom=96 square inches
Area of the living room =144 square inches
Area of the dollhouse that is not of the bedroom or living room
=576-(96+144)=576-240=336 square inches.
The area of the living room is 3/2 times the area of the bedroom
This is gotten by subtracting the area of the bedroom and living room from the total area of the house.

Answer:
- a ≈ 615.272
- b ≈ 1.61875
Step-by-step explanation:
My graphing calculator can solve this problem two ways. It can do a least-squares fit of the exponential data, or it can do a least-squares fit of the logarithm of the data. The answers come out different.
In "log mode", the parameters of the exponential equation are computed as ...
a ≈ 615.272
b ≈ 1.61875
__
With log mode turned off, the "a" parameter is lower (≈553.071), and the "b" parameter is higher (≈1.65573). This mode gives a better fit to the larger data values, at the expense of a poorer fit to the lower data values, as you might expect.
