Rational numbers are defined as "a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q." This quote can be broken down to make it easier to understand. In basic terms, a rational number is a real number that is an integer, fraction, terminating decimal, or repeating decimal.

Integer

An integer is any positive or negative whole number including 0. Examples of integers include 4, -9, and 0.

Fraction

All fractions that do not have a 0 denominator (which makes the number undefined) are rational numbers. Additionally, complex fractions are not always considered rational numbers. Complex fractions are fractions where either the numerator or denominator is a decimal or fraction itself. Examples of rational fractions include [tex]\frac{4}5}[/tex], [tex]\frac{7}{4}[/tex], and [tex]\frac{2}{2}[/tex].

Terminating Decimals

Terminating decimals are decimals that have a finite number of digits. This means that the decimal stops at some point. Examples of terminating decimals include 0.346, 0.47834, and 0.345832454525456

Repeating Decimals

Repeating decimals are any decimal that is not terminating but has some pattern that repeats for infinity. Examples of repeating decimals include [tex]0.\bar 9[/tex], [tex]0.\bar8\bar6[/tex], and [tex]0.\bar 5\bar7\bar8\bar4[/tex]. In this case, the bar notation represents numbers that repeat forever.

The table is an illustration of a quadratic function, and the range of Ella's table is 0 ≤ y ≤ 9

From the complete question, we have the following highlights:

The minimum output value is 0, and the maximum output value is 9

This means that the range of the table is 0 to 9

Express properly as:

0 ≤ y ≤ 9

Hence, the range of Ella's table is 0 ≤ y ≤ 9

The quadratic equation will have no real solutions.

Given quadratic equation is: [tex]ax^{2} +bx+c=0[/tex]

The discriminant(D) of a quadratic equation is [tex]D=b^{2}-4ac[/tex]. It depicts the nature of the roots.

[tex]D > 0[/tex] the roots are real and distinct.

[tex]D=0[/tex] the roots are real and equal.

[tex]D < 0[/tex]  the roots will be imaginary.

We have [tex]D=-16[/tex] which is negative.

So, the roots will be imaginary.

So, the given quadratic equation will have no real solutions.

Hence, the given quadratic equation has no real solutions.

Answer:

15/8 Hours

Step-by-step explanation:

To start, I would find see how long it takes to walk a mile.

1/3 · 3 = 1

1/4 · 3 = 3/4

So we now know that walking one mile takes 45 minutes. Next, I multiplied 1 mile by 2.5 and repeated the same process with the time.

3/4 · 5/2 = 15/8

Therefore, it takes 15/8 hours to walk 2.5 miles.

There were 8 people who surveyed exercise once a week or less out of the 50 people who were surveyed.

An equation is an expression that shows the relationship between two or more numbers and variables.

From the circle graph, percentage of the people surveyed exercise once a week or less = 100% - (10% + 40% + 20% + 14%) = 16%

Number of the people surveyed exercise once a week or less = 15% of 50 = 0.16 * 50 = 8

[tex]\huge\boxed{\sf \$54.81}[/tex]

Step-by-step explanation:

The cost of pet carrier = $21.89

The cost of 1 bag of cat food = $16.46

The cost of 2 bags of cat food = $16.46 × 2

= $32.92

Total cost:

= $21.89 + $32.92

= $54.81

[tex]\rule[225]{225}{2}[/tex]
