Answer:

The PTA will order 6 cheese pizzas.

Step-by-step explanation:

There is a 3:4 ratio for cheese pizzas to pepperoni pizzas.

If the number of pepperoni pizzas doubles, then the number of cheese pizzas must double as well.

So, 3:4 becomes 6:8.

The PTA will order 6 cheese pizzas.

Which sequence is modeled by the graph below?
Maru [420]

We have

a2 = 4

a3 = 2

a4 = 1

 calculate the difference

a3 - a2 = -2

a4 - a3 = -1

 The differences are not equal---------- >the sequence is not arithmetic.

 Getting the ratio:

a3/a2 = 0.5

a4/a3 = 0.5

 The common ratio is 0.5. Using the general form for a geometric series:

an = a1 r^(n-1)

for n = 2---------------- > a2=4

4 = a1 (0.5)^(2-1)

a1 = 8

therefore

an = 8 (1/2)^(n-1)

the answer is an = 8 (1/2)^(n-1)

the answer is none of those indicated in the question

The park shown is in the shape of a square. Is the perimeter rational or irrational? Area = 24,200 yd 2
romanna [79]

Answer:

Perimeter is irrational

<em></em>

Step-by-step explanation:

<em>The attachment is missing but the question is still answerable</em>

Given

Area = 24200 yd^2

Required

Determine if the Perimeter is rational or not

First, we need to determine the sides of the square;

Area = Length * Length

Substitute Area = 24200 yd^2

24200 = Length * Length

24200 = Length^2

Take Square root of both sides

\sqrt{24200} = Length

Length = 155.563492

The perimeter of a square is calculated as:

Perimeter = 4 * Length

Perimeter = 4 * 155.563492

Perimeter = 622.253968

<em>Because the value of </em><em>perimeter </em><em>can't be gotten by dividing two integers, then </em><em>perimeter is irrational</em>
