Please help me!!!<br> Will give 100 points.<br> Will give BRAINILEST
Oksana_A [137]

Step-by-step explanation:

The shape of the new pizza must meet the conditions:

  • Be an irregular polygon (different sides and/or angles).
  • Have at least five sides.
  • Have the approximately the same area as a 14" diameter circle.
  • Fit in a 14⅛" × 14⅛" square.
  • Be divisible into 8-12 equal pieces.

For simplicity, I will choose a polygon with 5 sides (a pentagon), and I will use 2 right angles (a "house" shape).

Split the pentagon into a rectangle on bottom and triangle on top.  If we cut the rectangle into 8 pieces like a regular pizza, and the triangle in half, we get 10 triangles.

Now we just need to figure out the dimensions.  The area of a 14" circular pizza is:

A = πr²

A = π (7 in)²

A ≈ 154 in²

That means the area of each triangle slice needs to be 15.4 in².  If we make the total width of the pentagon 14", then the width of each triangle is 7", and the height of each triangle is:

A = ½ bh

15.4 in² = ½ (7 in) h

h = 4.4 in

Which makes the total height of the pentagon 3h = 13.2 in.

So, our 13.2" × 14" pentagon has at least 5 sides, is irregular, has the same area as a 14" diameter circle, fits in a 14⅛" × 14⅛" square, and can be divided into 8-12 equal pieces.

Of course, there are many possible solutions.  This is just one way.

For which function is f(x) equal to f-1(x)?
Readme [11.4K]
Let's solve for f.
y=f−1x
Step 1: Flip the equation.
f−x=y
Step 2: Add x to both sides.
f−x+x=y+x
f=x+y
Answer:
f=x+y

Find the missing leg of a right triangle if one leg is 5 and the hypotenuse is 13
Softa [21]
Use Pythagorean theorem (a squared is equal to c squared minus b squared)

Where a is the unknown leg, c is the hypotenuse and b is the known leg

a^2 = 13^2-5^2 which is 144

Then square root one hundred and fourty four to get rid of the power on a

Square root of one hundred and fourty four is twelve
