7 0

Because we are dealing with area, we have to square the difference of the 2 polygons.40 / 15 = 2.6666666667 2.6666666667^2 = 7.1111111111

 So, the 40 yard polygon has 7.1111111111times the area of the 15 yard polygon.

Answer: 64:9

Step-by-step explanation:

The polygons here have a scale factor of 40:15=8:3 and is simplified to 8/3. Their areas will be 8/3 squared or 64/9.

Solution

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the formula for slope

$m=\frac{y_2-y_1}{x_2-x_1}$

STEP 2: Pick two points

STEP 3: Find the unit price per cup

Since 4 cups cost $5, one cup will cost

$\frac{5}{4}=\text{ \$}1.25\text{ per cup}$

Therefore, the answer is $1.25

dedylja [7]

Answer:

$6488.19

Step-by-step explanation:

To solve this problem we use the compounded interest formula:

$amount = principal(1 + (r \n))^({n}{t})$

a = $2600(1+(0.0675/1))¹*¹⁴

a = $6488.19

Consider the function represented by 9x+3y= 12 with x as the independent variable. How can this function be written using

Ivenika [448]

Answer:

f(x)=-3x+4

(can't see some of your choices)

Step-by-step explanation:

We want x to be independent means we want to write it so when we plug in numbers we can just choose what we want to plug in for x but y's value will depend on our choosing of x.

So we need to solve for y.

9x+3y=12

Subtract 9x on both sides

3y=-9x+12

Divide both sides by 3:

y=-3x+4

Replace y with f(x).

f(x)=-3x+4
