Rational numbers are numbers that can be written as a fraction of two integers (as long as the denominator isn’t 0).
5 = 5/1, so it’s rational
1/2 and 1/3 are fractions, so they’re rational.
As decimals, rational numbers either stop or repeat.
1/2 = 0.5 (That stops.)
1/3 = 0.3333333… (That’s repeating.)
Of the two possible answers left, does one of them repeat? If so, it must be the other answer.
Step-by-step explanation:
A playing card is in the form of a rectangle whose perimeter is equal to 28 cm and area is 45 cm².
If l and b are length and breadth of the rectangle.
Area,
Perimeter,
Put the value of l from equation (1) to equation (2). So,
Put the value of b in equation (1),
If b = 5 cm
If b = 9 cm
So, the dimensions of the playing card is 9 cm by 5 cm.

Question:
I met a men who said if you can guess my age, i will pay you one dollar for each year that i have lived. I will also give you two hints. If you take my age and divide it by any odd number greater than 1 and less than 9 you will get a remainder of 1. But if you take my age and divide it by any even number greater than 1 and less than 9 you will not get a remainder of 1. how much money could you earn?
Answer:
The man's age is 106 years
Amount earned is $ 106.00
Step-by-step explanation:
Here we have
3 × a = Age +1
5 × b = Age +1
7 × c = Age +1
Age is even, therefore, a, b and c are odd numbers
Since 3, 5 and 7 are factors of Age + 1
Then, 3 × 5 × 7 is a factor. That is 3 × 5 × 7 = 105
Therefore, 105 + 1 or 106 is a possible solution as an even number divided by another even number will not have a remainder of 1.
The age of the man is 106 years
Therefore, the amount earned = $ 1.00/year × 160 years = $ 106.00
Answer:
264
Step-by-step explanation:
First let's try the distributive property first
(-12x3)+(-12x-25)
-36+(300) Keep in mind that two negatives equal a positive
-36+300
264
There is another way to do this though
PEMDAS tells us to use what is in the parenthesis first so let's do that
-12(-22) 3-25 equals -22
264 Once again two negatives equal a positive
Your answer could be 264 or any one of these steps depending on what you need your answer to be but I'll put 264 as my "answer"
