The only set that only has rational numbers is the first one:
{1/3, -3.45, √9}
<h3>
Which of the given sets contains only rational numbers?</h3>
A rational number is a number that can be written as the quotient of two integers.
If we look at the first set, the elements are:
- 1/3 which is a rational number.
- -3.45 = -345/100 which is a rational number
- √9 = 3 = 3/1 which is a rational number.
In the other sets we can see elements like:
√37, √44, or √2 which are all irrational numbers, then the only correct option is the first one.

And isosceles triangle always equals 180 degrees so to find the value of x what number would you need for the value to be 180
The solution of the inequality is x ≥ -3 and the graph is shown below
<h3>Graph of inequalities </h3>
From the question, we are to determine the graph that represents the given inequality
The given inequality is
−3x + 1 ≤ 10
First, we will solve the inequality
−3x + 1 ≤ 10
Subtract 1 from both sides
−3x +1 -1 ≤ 10 - 1
−3x ≤ 9
Divide both sides by -3 and<u> flip the sign</u>
x ≥ -3
The graph of the inequality is shown below

A % is out of a hundred, so you don't need the %/100. Then, you wouldn't do cross multiplication, you would just divide 15/27. Remember, it would be 15/27 because it's percent markup, not the percent the price increased by. So, doing that simple calculation on a calculator you get 0.5555. This converted to a percent is just moving the decimal to the right twice, or multiplied by a 100. That would give you 55.55%, and that's your answer. Make sense?
