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.

Answer:

The cost of one day lily = $ 11,

The cost of one shrub = $ 2.

Step-by-step explanation:

Let x be the cost of one day lily and b be the cost of one shrub,

Michaela spent $148 in 12 day lilies and 8 shrubs.

⇒ 12 x + 8 y = 148

⇒ 3 x + 2 y = 37 ----------(1)

While, Julia spent $92 on 6 day lilies and 13 shrubs.

⇒ 6 x + 13 y = 92 --------(2)

2 × Equation (1),

⇒ 6 x + 4 y = 74 --------(3)

Equation (2) - Equation (3),

9 y = 18

⇒ y = 2

By substituting this value in equation (1),

⇒ 3 x + 4 = 37

⇒ 3 x = 33

⇒ x = 11

Hence, the cost of one day lily = x = $ 11

And, the cost of one shrub = y = $ 2

WILL MARK BRAINLIEST!!!!!

RUDIKE [14]

The data is larger for intermediate values of x, so the parabola opens downward. That leaves only the 2nd and 4th choices, where the x² coefficient is negative.

To determine which of those is appropriate, it is only necessary to consider x=1. The 2nd choice will give a y-value near 100; the 4th choice will give a y-value near 250.

The fourth choice is appropriate:

... y = -9.16x² +73.04x +183.3

_____

Alternatively, you can consider that for the x-coordinate of the vertex to be positive (it's about +4), the coefficients of the x² and x terms must have opposite signs. Using this consideration, you don't even need to evaluate the expression to determine that the 4th choice is the correct one.
