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)

Answer:
7.5 minutes
Step-by-step explanation:
The problem says that each camera has 1 hour of digital space. Because you calculated that the total time of speeches will be 52.5 minutes, you can do as follows:

Answer:
c:-$12
Step-by-step explanation:
34+30=64.
then 64 - 76=-12
Answer:
-12
Step-by-step explanation:
You start off with $34 so +34
Then you spend $76 so -76
Then you deposit $30 so +30
There are several ways to go about this but i find the easiest way is to add the positives first.
We're going to say 34+30=64
Next we subtract 76 from 64= -12
You go about this in the same way you would if it didn't have a negative sign in front of it. Then since the 76 is the larger number you add the negative sign.
-76
- 64
-----------
-12

The total cost of the trip can be found by adding these components:
Entrance fee per student: $5(29)
Lunch costs: $4(29 + 6)
Bus fees: $25 + 8($2 + $3)
Total cost:
5(29) + 4(35) + 25 + 8(5)
Which of these are equivalent expressions of the total cost that use the properties of operations to simplify the math?
5(15 + 14) + 4(31 + 4) + 25 + 40
5(20 + 9) + 4(30 +5) + 25 + 40
5(17 + 12) + 4(33 + 2) + 25 + 40

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

This table DOES NOT display a function. Which ordered pair could be removed to create a function from this table?
A. (3, 6)
B. (10, 9)
C. (11, 11)
D. (5, 8)
Answer
i think 3,6 but im not sure
Step-by-step explanation:
(5,8) needs to be removed in order to create a function. Because there's already (5,7). That means x = 5 can't be used anymore. Function only gives a single y-value with only a single x-value. If a single x-value gives 2 y-values, then it's not a function.
A gym charges a one-time fee of $75 to join, plus membership dues of $25 per month. Which equation represents the total cost, C, of belonging to the gym for m months?
A. C = 25m – 75
B. C = 25m + 75
C. C = 75m + 25
D. C = 75m – 25
Answer:
B
Step-by-step explanation:
75 first then 25 is 25m+75
if 4r+3trs-3u+2=12s+r-1, then t =
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.

2. Dan uses a coupon at CVS that saves him 20%. On his receipt, he sees that he saved $3. How much was his bill before he used the coupon?
Answer:
For the second question the ANSWER is: 15
Step-by-step explanation:
Before he saves 20% he had to pay 15$.
1) If the 20 percent makes her save 3$ than we have to multiply 3$ by 5 so the percentage would be 100
2) 5*3 = 15$
- Checking -
1) We do 100/15 so we can find the one percent.
2) The one percent is 0.15
3) We do 0.15 * 20 so we can find the 20 percent of the total money.
4) The answer is equals 3 which is correct.
