Answer: A Scale factor is a number which multiplies or scales a number in an equation.

Perimeter ratio is the ratio of the perimeter to the area.

Area ratio is the ratio of the total amount of usable floor a land has

Step-by-step explanation:

Scale ratio can be established by this simple equation y=CX where C is the scale factor.

Perimeter ratio; perimeter = 2(L+B) where L is length and B is breadth

Area = L×B

Therefore perimeter ratio = 2(L+B)/L×B

Area ratio; L2 ×W2/L1×W1 where L1 and L2 are the lengths and W1 and W2 are the widths.

During one month, a homeowner used 600 units of electricity and 100 units of gas for a total cost of $344. The next month, 400 u

Answer: the cost per unit of gas is $0.38

Step-by-step explanation:

Let x represent the cost per unit of electricity.

Let y represent the cost per unit of gas.

During one month, a homeowner used 600 units of electricity and 100 units of gas for a total cost of $344. It means that

600x + 100y = 344- - - - - - - - - -1

The next month, 400 units of electricity and 250 units of gas were used for a total cost of $299.

It means that

400x + 250y = 299- - - - - - - - - -1

Multiplying equation 1 by 400 and equation 2 by 600, it becomes

240000x + 40000y = 137600

240000x + 150000y = 179400

Subtracting, it becomes

- 110000y = - 41800

y = - 41800/- 110000

y = 0.38

Substituting y = 0.38 into equation 1, it becomes

600x + 100 × 0.38 = 344

600x + 38 = 344

600x = 344 - 38 = 306

x = 306/600

x = 0.51

For accounting purposes, the value of assets (land, buildings, equipment) in a business are depreciated at a set rate per year.

Scrat [10]

Answer:

So, option d is correct i.e,

V₀ = $393,000, b = 0.85, and the value after 7 years is $125,986.80

Step-by-step explanation:

The formula given is V(t)=V₀(b)^t

The value of V₀ (the actual worth) is:

V₀ = $393,000

The value of b is :

b= (1-15%) = (1-0.15) = 0.85

Value of assets after 7 years is:

t= 7, V₀ = $393,000, b=0.85

putting values in formula:

V(t) = Vo(b)^t.

V(7)= $393,000 * (0.85) ^ 7

V(7)= $393,000 * (0.320)

V(7)= $125986.80

So, option d is correct i.e,

Vo = $393,000, b = 0.85, and the value after 7 years is $125,986.80
