Answer:

<h3>Rational numbers</h3>

Step-by-step explanation:

A rational number is a number that can be written as a ratio of two integers. The are expressed as fractions. Given the value 8/9, this value is a fraction and is written as a ratio of two integers 8 and 9.

The value is neither a real number, nor an integer because integers and whole numbers are not expressed as fractions.

Natural numbers are also whole numbers starting from 1 and above. Hence 8/9 is not a natural number as well.

Note that irrational numbers are also classified as real numbers and they can not be written as a ratio of two integers.

Conclusively, 8/9 is only classified as a rational number

ExtremeBDS [4]

Answer:

Cyrus needs to order 3 full pizzas to feed his 11 friends .

Step-by-step explanation:

The number of friends invited  = 11

Share of pizza for each friend = 1/4 pizza

Now,  as  1 friend eats 1/4 of  a pizza.

⇒  11 friends eat  = 11 \times \frac{1}{4}  = 2.75

So, 11 friends can eat 2 .75 pizza.

Since pizza come as a whole number.

And 2. 75 is nearly equal to 3.00

Hence,  Cyrus needs to order 3 full pizzas to feed his 11 friends .

For which function does f decrease by 15% every time x increases by 1
LenaWriter [7]

Answer:

f(x) = 0.85^{x}

Step-by-step explanation:

The exponential function that decrease by 15% every time x increases by 1 is given by:

f(x) =  {(1 - 0.15)}^{x}

We simplify the parenthesis to get:

f(x) = 0.85^{x}

Therefore the decrease by 15% every time x increases by 1 is

f(x) =  {0.85}^{x}

The second choice is correct.
