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.

Step-by-step explanation:
no it's 22 :D...............
The angle of depression is 29.0521°. So it is a safe landing.
Step-by-step explanation:
Step 1:
The plane is flying at a height of 25,000 feet and 45,000 feet away from the landing strip. Assume it lands with an angle of depression of x°.
So a right-angled triangle can be formed using these measurements. The triangle's opposite side measures 25,000 feet while the adjacent side measures 45,000 feet. The angle of the triangle is x°.
To determine the value of x, we calculate the tan of the given triangle.
Step 2:
The length of the opposite side = 25,000 feet.
The length of the adjacent side = 45,000 feet.
So x = 29.0521°. Since x < 30°, it is a safe landing.
Answer:
I simply listed the factors of 24, and tested which ones worked in this equation: P = 2a + 2b.
So the factors listed were:
24 x 1
12 x 2
8 x 3
6 x 4
After testing each one of these, 6 and 4 had worked for me.
P = 2(6) + 2(4)
P = 12 + 8
P = 20
Therefore, the dimensions of this rectangle are 6 and 4.
