Answer:
Step-by-step explanation:
I'm going to guess that 1/2 the size means the sides are 1/2 the size.
Square 1 has an area of 24. The sides are s, so the area is found by using s^2
The second square is made from sides that are 1/2 s
Area = 1/2 s * 1/2 s
Area = 1/4 s^2
Area 1 / area 2 = 24 / x^2 = s^2 / 1/4 s^2 = 1/0.25
It already is a decimal:)

Answer:
either 20* and 140*, or 80* and 80*
Step-by-step explanation:
This problem can be solved using the formula for the annuity.
Principal amount = price of the sofa(1 + sales tax)
where
price of the sofa= $670
sales tax =7.94%
Principal amount = $723.2
solve for the amortization using the formula:
Amortization = Principal amount[(i(1+i)^n]/[(1+i)^n-1]
where
i= 11.05%/12=.92%
n= 3years x 4 payments/year=36
Principal amount = $723.20
Amortization = $23.68
Get the sum of annuity
Sum of annuity=Amortization[(1+i)^n-1]/i
Sum of annuity= $852.84
The answer is letter d. Douglas paid a total of $852.84 for the sofa.
