Answer:

2.41 * n = y

Step-by-step explanation:

From the table, we can notice that the value;

y/n is a constant for each of the rows

this represents the individual costs of each of the books

So, we have it that;

7.23/3 = 4.82/2 = 9.64/4 = $2.41

So, the books have a unit cost of $2.41

Hence, by multiplying the number of books n by 2.41 we can get the cost y

So mathematically, we have the relation as;

2.41 * n = y

Juan wishes to build a garden at the bottom of his property. He wants to split it in two, like the diagram below, so he can plan
SCORPION-xisa [38]

Answer:

20 ft by 60 ft

Step-by-step explanation:

"What should the dimensions of the garden be to maximize this area?"

If y is the length of the garden, parallel to the stream, and x is the width of the garden, then the amount of fencing is:

120 = 3x + y

And the area is:

A = xy

Use substitution:

A = x (120 − 3x)

A = -3x² + 120x

This is a downward facing parabola.  The maximum is at the vertex, which we can find using x = -b/(2a).

x = -120 / (2 · -3)

x = 20

When x = 20, y = 60.  So the garden should be 20 ft by 60 ft.

Another wooden plank is leaning against an outside wall of a building. The bottom of the plank is 9 ft from the wall. The length
Vladimir [108]
Given:
bottom of the plank or ground is 9 feet from the wall
length of the plant is 41 ft
height of the wall is unknown.

Let us use the Pythagorean theorem.

a² + b² = c²
a² + (9ft)² = (41ft)²
a² + 81 ft² = 1,681 ft²
a² = 1,681 ft² - 81 ft²
a² = 1,600 ft²
√a² = √1,600 ft²
a = 40 ft

The height of the wall is 40 ft.

Answer:

x = \frac{C-By}{A}

Step-by-step explanation:

Given

Ax + By = C ( subtract By from both sides )

Ax = C - By ( divide both sides by A )

x = \frac{C-By}{A}
