Pizza Palace cuts a medium pizza into 8 slices. The same size pizza at Pizza Pioneers is cut into 16 slices. Jasmine ate 4 slice
ludmilkaskok [199]

Pizza palace cuts the medium size pizza into 8 slices.

Pizza pioneers cuts the same size pizza into 16 slices.

Jasmine ate 4/16 pizza in Pizza pioneers,

The ratio of Pizza palace slices to Pizza pioneer slices is;

Pizza palace : Pizza pioneer = 8 : 16 = 1 : 2

Let fraction of pizza in Pizza palace to 4/16 pizza in Pizza pioneer be;

x : 4/16 , Simplified becomes x : 1/4

<u>Comparing ratios:</u>

Pizza Palace slices : Pizza Pioneer slices = 1 : 2

and

Pizza Palace fraction : Pizza Pioneer fraction = x : 1/4

As Pizza Palace slices are half those in Pizza pioneer;

x should be half the fraction of slices Jasmine ate in Pizza Pioneer

i.e x = 1/2 × 1/4 = 1/8

Therefore the fraction of pizza from Pizza Palace which is equal to 4/16 slices from Pizza Pioneer is 1/8 .

PLEASE HELP! What is the approximate area of the shaded region? use 3.14 for Pi
tiny-mole [99]

Answer:

A. 16.86 square inches

Step-by-step explanation:

Area of Circle = \pi r^2, where r = radius.

Area of Rectangle = l * w, where l = length and w = width.

We are given the radius of the circle as 1, and we use π as 3.14

  • 3.14*1^2
  • 3.14*1
  • 3.14

Next, we find the area of the rectangle.

  • 5*4
  • 20

Lastly, we subtract 3.14 from 20.

  • 16.86

Therefore, the answer is A. 16.86 square inches.
