Anna71 [15]

Answer:

The Choice N#1 will give more pizza for your money

Step-by-step explanation:

step 1

Find the area of one slice Choice #1

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=22/2=11\ in$ ----> the radius is half the diameter

assume

$\pi =3.14$

The area of one slice is equal to

$A=(1/8)\pi r^{2}$

substitute

$A=(1/8)(3.14)(11)^{2}$

$A=47.4925\ in^{2}$

Divide the cost by the area

$4.95/47.4925=0.10\frac{\$}{in^{2}}$

step 2

Find the area of the entire personal pizza Choice # 2

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=6/2=3\ in$ ----> the radius is half the diameter

assume

$\pi =3.14$

substitute

$A=(3.14)(3)^{2}$

$A=28.26\ in^{2}$

Divide the cost by the area

$3.75/28.26=0.13\frac{\$}{in^{2}}$

therefore

The Choice N#1 will give more pizza for your money

Point M( -3, -2) is rotated 270° counterclockwise and then reflected over the x-axis. What are the coordinates of M'?

White raven [17]

Rotation involves moving a point around a center

The coordinates of M" are (-2,-3)

<h3>How to determine the coordinates of M'</h3>

The pre-image M is given as:

M =(-3,-2)

The rule of 270 degrees counterclockwise rotation is:

$(x,y) \to (y,-x)$

So, we have:

M' = (-2,3)

The rule of reflection over the x-axis is:

$(x,y) \to (x,-y)$

So, we have:

M" = (-2,-3)

Hence, the coordinates of M" are (-2,-3)
