Answer:

≈ 1758.4 m

Step-by-step explanation:

The distance is equal to the length of 5 circles with a diameter of 112 meters

distance = 5 · π · d = 5 · 3.14 · 112 ≈ 1758.4 m

Answer:

The coordinates of the midpoint of the two vertices are

(0,2) (Third option)

Step-by-step explanation:

<u>Coordinates Of A Midpoint </u>

Given a pair of points in the plane

$\displaystyle P_1\ (x_1,y_1)\ ,\ P_2(x_2,y_2)$

the coordinates of the midpoint of both points are

$\displaystyle x_m=\frac{x_1+x_2}{2}$

$\displaystyle y_m=\frac{y_1+y_2}{2}$

The vertices given in the figure are

$\displaystyle v_1(-4,1),\ v_2\ (4,3)$

So the x-coordinate of their midpoint is

$\displaystyle x_m=\frac{-4+4}{2}=\frac{0}{2}=0$

And the y-coordinate of their midpoint is

$\displaystyle y_m=\frac{1+3}{2}=\frac{4}{2}=2$

So the coordinates of the midpoint of the two vertices are

(0,2), the third option

A homemade loaf of bread turns out to be a perfect cube. Five slices of bread, each 0.6 inch thick, are cut from one end of the

erastovalidia [21]

A cube has all sides of equal length.

So let the side be x

that will be length = width = height = x

Now, when we cut the loaf into 5 equal slices, the length and height of the slices are the same as the original loaf. But the width will become less with each slicing. Here the width corresponds to the thickness of the slices.

For each slice the dimensions are -

Length = x

height = x

width = 0.6

Volume of the original loaf is x³.

Volume of 5 slices is 5(x * x * 0.6).

Volume that is left after the cutting the slices is 235 inch³.

So, equation of the volume is=

x³ - 5(0.6x²) = 235

Solve for x using this equation.

x³ - 3x² = 235

x³ - 3x² - 235 = 0

Using a graph calculator to find the roots, we get

x = 7.35

Hence the dimensions of the original loaf is 7.35 inches for each side.

Please find attached the graph.

In Andrew’s Furniture Shop, he builds bookshelves and tables. Each type of furniture takes him about the same time to make. He f

A. You may set the variables in either order. But for argument sake, let's set as follows:

x = Amount of bookshelves
y = Amount of tables

B. Because of the amount of things you need to make, the following is an inequality using those variables.

x + y > 25

Plus you can determine a second inequality based on the amount of money that you have to spend.

20x + 45y < 675

Finally you may also add in that each value must be greater than or equal to zero, since they cannot have negative tables.

C. By solving the system and looking at basic constraints when graphed, you can see the feasible region has 4 vertices.

(0,0)
(18, 7)
(0, 15)
(33.75, 0) or (33, 0) if you insist on rounding.
