1. Rational.

2. Whole.

3. Irrational.

4. Whole.

5. Integer.

6. Irrational.

<h3>What is the set of the number -31.8?</h3>

It is a terminating decimal, hence it is a rational number.

<h3>What is the set of the number 6425?</h3>

It is a non-negative non-decimal number, hence it is a whole number.

<h3>What is the set of number 2pi?</h3>

pi is an irrational number, as it is a non-terminating decimal, hence 2pi is also an irrational number.

<h3>What is the set of the number 0?</h3>

It is a non-negative non-decimal number, hence it is a whole number.

<h3>What is the set of the number negative square root of 16?</h3>

The square root of 16 is 4, hence -√16 = -4, which is a negative non-decimal number, hence it is an integer.

<h3>What is the set of the square root of 24?</h3>

The square root of 24 is non-exact, hence it is a non-terminating decimal , so an irrational number.

pav-90 [236]

Answer:

10x + 25y = 285

One $25 gift cards with 26, $10 gift cards.

Three $25 gift cards with 21, $10 gift cards and

Five $25 gift cards with 16, $10 gift cards.

Step-by-step explanation:

I can purchase gift cards for $10 or $25. I have spent $285 on gift cards.

If I have purchased x number of $10 gift cards and y number of $25 gift cards then the equation that models the situation in standard form will be given by

10x + 25y = 285 .......... (1)

Now, for y = 1, x = 26

For, y = 3, x = 21

For, y = 5, x = 16

So, here are the three combinations of gift cards that I could have purchased.

One $25 gift card with 26, $10 gift cards.

Three $25 gift cards with 21, $10 gift cards and

Five $25 gift cards with 16, $10 gift cards. (Answer)

A running track in the shape of an oval is shown. The ends of the track form semicircles.
tigry1 [53]

Answer:

Two semi circles would equal one circle.

The perimeter of a circle is PI x diameter.

The diameter of the circle is shown as 56 m

The perimeter of the 2 ends = 56 x 3.14 = 175.84

The length of the inside of the track is given as 130 m, and there are 2 sides so 130 + 130 = 260 m.

Total perimeter = 260 + 175.84 = 435.84 m.
