Rational Numbers -- Operations
Remember -- When performing operations with rational numbers, they should both be in the same form -- fractions or decimals -- and then operations should be performed accordingly

Miles is painting pumpkins for halloween. He has 3/4 of a gallon of paint. Each pumpkin needs .03 gallons to cover the pumpkin. How many pumpkins can he paint?

Answers

Answer 1

Answer:

Stop cheating on that assignment

explanation:

Learn something .

Answer 2

Answer: 2/5 of the pie is .4 added to .375 equals .775 they ate all together.

3/4 is .75 gallon. To find how many pumpkins he can paint, divide .75÷ .03 = 25 pumpkins.

Step-by-step explanation:

To convert fractions to decimals, divide the numerator by the denominator. 7/8 = .875

To convert a decimal to a fraction, use the digits as the numerator and make the denominator a power of 10 with one place more than the numerator. Then reduce or simply. Examples:

.5 = 5/10 = 1/2

.75 = 75/100 = 3/4

.125 = 125/1000 = 1/8

I hope this helps you!

Please solve k-3/4 = 10,
Z+5/7 = -3, and
9+t/12 = -3 with work too please

Answers

Answer:

Step-by-step explanation:

Add the 3/4 to cross it out on the left side and whatever you do to one side you do to the other side. so you add 3/4 or .75 on to 10 to get 10.75.

k-3/4=10

k=10.75

Subtract the 5/7 from the Z and subract it from -3 to get, -3.71.

Z+5/7=-3

Z=3.71

Subtract 9 from the left side and subtract 9 from the right side.

9+t/12=-3

t/12=-12

Then you would multiply by 12 from the left side and multiply by 12 from the right side.

t/12=-12

t=-144

Which statement is true?

A rational number must show repeating digits after the decima
A rational number must show terminating digits after the decimal
An irrational number cannot be written as a repeating decimal.
An irrational number may show terminating digits after the decimal

Answers

Answer:

An irrational number may show terminating digits after the decimal

Step-by-step explanation:

Examples of Rational Numbers

Number 9 can be written as 9/1 where 9 and 1 both are integers.  0.5 can be written as ½, 5/10 or 10/20 and in the form of all termination decimals.  √81 is a rational number, as it can be simplified to 9 and can be expressed as 9/1.  0.7777777 is recurring decimals and is a rational number

Examples of Irrational Numbers

Similarly, as we have already defined that irrational numbers cannot be expressed in fraction or ratio form, let us understand the concepts with few examples.

5/0 is an irrational number, with the denominator as zero.

π is an irrational number which has value 3.142…and is a never-ending and non-repeating number.

√2 is an irrational number, as it cannot be simplified.

0.212112111…is a rational number as it is non-recurring and non-terminating.

There are a lot more examples apart from above-given examples, which differentiate rational numbers and irrational numbers.

Properties of Rational and Irrational Numbers

Here are some rules based on arithmetic operations such as addition and multiplication performed on the rational number and irrational number.

#Rule 1: The sum of two rational numbers is also rational.

Example: 1/2 + 1/3 = (3+2)/6 = 5/6

#Rule 2: The product of two rational number is rational.

Example: 1/2 x 1/3 = 1/6

#Rule 3: The sum of two irrational numbers is not always irrational.

Example: √2+√2 = 2√2 is irrational

2+2√5+(-2√5) = 2  is rational

#Rule 4: The product of two irrational numbers is not always irrational.

Example: √2 x √3 = √6 (Irrational)

√2 x √2 = √4 = 2 (Rational)

Answers

Answer:

y = -3x - .25 or y = -3x + -.25

Step-by-step explanation:

y = slope (x) + y-intercept

Nikki used the calculations shown to determine whether a carton of 12 eggs or a carton of 18 eggs was the better buy.

A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39.
Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg
Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg
The 12-egg carton has the lower unit cost, so it is the better buy.

What was her first error?
She should have divided the cost of the carton by the number of eggs to find the price per egg.
She should have divided the number of eggs by the cost of the carton to find the price per egg.
She made a computational error when multiplying to find the unit price of the two cartons.
She made an error in choosing the eggs with the lower unit cost to be the better buy.

The solution of the expression for the value of t will be t = ( 12s -3r +31) / 3rs.

What is an expression?

Numeral variables and operations marked by the signs for addition, subtraction, multiplication, and division are combined in the mathematical equation.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented using mathematical symbols. They can also signify other characteristics of logical grammar, such as the operation order.

Given expression is 4r+3trs-3u+2=12s+r-1. the value of t for the expression will be solved as:-

4r+3trs-3u+2=12s+r-1,

3trs = 12s - 4r +r + 34 -2 - 1

3trs = 12s - 3r + 31

t = ( 12s -3r +31) / 3rs

Therefore, the solution of the expression for the value of t will be t = ( 12s -3r +31) / 3rs.
