is the decimal 13/3 a rational number? explain

Answers

13/3 is not a rational number because the quotient of 13 divided by 3 is 4.3 repeated. Any repeating number is not rational. Hope that helps!
Yes.

All rational numbers can be represented by a ratio of two integers. Since 3 and 13 are both integers, 13/3 is rational.

The deciml form of 13/3 is 4.3333... The decimal form of all rational numbers are either repeating or terminating. This one repeats.

What is the correct solution to this problem? A number divided by 3 is four more than –11. What is the number?

A-45

C-7/3
D45

Answers

If we represent the number as n, we get n/3=-11+4 since that number divided by 3 is 4 more than -11. Therefore, we get n/3=-7. Multiplying both sides by 3, we get n=-21

how can you quickly calculate 20 percent of any bill amount?

Answers

Move the decimal point in your pretax bill one place to the left to get $5.375 from $53.75.Round up to the next easy number: $5.40.Double that number to get $10.80, which is 20% of your original bill.

Answer:

There are many ways to do this calculation. Few are listed below.

1. Whenever we say percent, that means divided by hundred. And any number divided by 100 will result in putting a decimal to two places left. Like 20% will becomes [tex]\frac{20}{100}[/tex] = 0.20

And you can multiply the bill amount with 0.20 mentally.

2. You can also simply divide the total bill amount by 5, it will be equal to  20% of the total bill amount. Like if bill amount is $200.

[tex]\frac{200}{5}=40[/tex] and [tex]0.20\times200=40[/tex]. Both values are same.

How to write 75 1/3 % as a fraction in simplest form

Answers

Answer:

The simplified form of the provided fraction is [tex]\frac{226}{3}\%[/tex].

Step-by-step explanation:

Consider the provided fraction.

The provided fraction can be written as:

[tex]75\frac{1}{3}\%[/tex]

Convert the provided mixed number into a proper fraction.

Multiply the number 75 with 3 and add 1 to the obtained number.

[tex]75\frac{1}{3}\%[/tex]

[tex]\frac{(75\times 3+1)}{3}[/tex]

[tex]\frac{225+1}{3}\%[/tex]

[tex]\frac{226}{3}\%[/tex]

Hence, the simplified form of the provided fraction is [tex]\frac{226}{3}\%[/tex].

Final answer:

To convert 75 1/3 % to a fraction in simplest form, first change the mixed number to an improper fraction, then write it over 100, and finally simplify by dividing both numerator and denominator by their greatest common divisor.

Explanation:

To convert 75 1/3 % to a fraction in simplest form, start by understanding that a percent is a ratio whose denominator is 100. Therefore, 75 1/3 % can be expressed as the fraction 75 1/3 over 100.

First, convert the mixed number to an improper fraction. Multiply the whole number 75 by the denominator 3 and add the numerator 1:

75 * 3 = 225225 + 1 = 226

Now, 75 1/3 as an improper fraction is 226/3. Write this as a fraction over 100:

226/3 % = (226/3) / 100 = 226/300

To simplify this fraction, we look for the greatest common divisor of 226 and 300, which is 2. Divide both the numerator and the denominator by 2 to get:

Numerator: 226 / 2 = 113Denominator: 300 / 2 = 150

The fraction in simplest form is therefore 113/150.

explain ehy the square root of 64 has a positive and a negative value.

Answers

The square root of 64 is 8, or -8

This is because 8 times 8 is 64

And -8 times -8 is 64 (because a negative times a negative is a positive)
The square root of 64 has both a negative and positive value because as we know it's 8 and -8. To square, you simply multiply the number by its self twice, since a negative number time a negative number is a positive number and a positive number times a positive number is also positive so -8x-8=64 and 8x8=64.

Final answer:

The question involves calculating various set operations in interval notation, including the union, intersection, and complements using intervals A, B, and set C (negative real numbers) within the universal set of real numbers R.

Explanation:

The student is working with set operations in interval notation, particularly focusing on the union, intersection, and complement relative to the set of real numbers R. Given intervals A=[-7,1], B=(-1,5), and set C being the negative real numbers, we need to perform various set operations.

A⋃B is the union of A and B, which is the set of all elements in either A or B.A∩B∩C is the intersection of A, B, and C, which represents all elements common to all three sets.A∩(B⋃C) represents the intersection of A with the union of B and C.A¹ ⋃ B¹ ⋃ C¹ is the union of the complements of A, B, and C relative to the universal set R.(C-A)⋃(B-C) represents the union of the set difference of C and A with the set difference of B and C.

Jon travels 1/2 mile in 1/4 hour. Find the unit rate in miles per hour.

Answers

Final answer:

To find the unit rate in miles per hour, divide the distance by the time. In this case, Jon travels at a unit rate of 2 miles per hour.

Explanation:

To find the unit rate in miles per hour, we need to convert the given information into the same units. Jon travels 1/2 mile in 1/4 hour, so we can simplify the fraction to 2/4, which is equal to 1/2. This means Jon travels 1/2 mile every 1/4 hour. To find the unit rate, we divide the distance (1/2 mile) by the time (1/4 hour).

1/2 mile ÷ 1/4 hour = 2 miles per hour

Therefore, the unit rate at which Jon travels is 2 miles per hour.
