The name of the sets of the numbers to which each of the given number belongs is:

  1. 7 = Natural number. Integer. Rational number.
  2. √23 = Irrational number.
  3. л = Irrational number.
  4. O = Rational number. Integer.
  5. -0.5 = Rational number.
  6. -2.5 = Rational number.
  7. √0.09 = Rational number.
  8. -√0.9 = Irrational number.

<h3>What are sets of numbers?</h3>

These are the various types of number groups that exist for categorizing numbers.

Natural numbers are all positive numbers from 1 to infinity while integers are positive and negative whole numbers. A decimal cannot be an integer as a result.

Rational numbers are discrete which means that they are terminating and eventually stop going while irrational numbers will keep going to infinity and are therefore non-terminating.

Stels [109]
The question can be answered using ratio and proportion.
In 40 minutes, Tracy can rake 4 bags of leaves. In 2 hours (which is equivalent to 120 minutes), how many bag will it be?

Making the equation.
4 : 40 = BAGS : 120
4 x 120 = 40 x BAGS
480 = 40 (BAGS) // Divide both sides by 40
BAGS = 12.

So there will be 12 bags of leaves.

Two men, 400 feet apart, observe a balloon between them it is the same vertical plane as they are. The respective angles of elev
slava [35]
The answer is 471 feet.

If A = man to left of balloon 
<span>B = balloon </span>
<span>C = man to right of balloon </span>

<span>∠BAC = 75°20' </span>
<span>∠BCA = 49°30' </span>
<span>∠ABC = 180 - 75°20' - 49°30' = 55°10' </span>
<span>AB = 400 ft </span>

<span>Now we have to find the value of x, which is the side opposite to angle of 75°20' </span>

<span>Using Law of Sines: </span>
<span>x/sin(75°20') = 400/sin(55°10') </span>
<span>x = 400 * sin(75°20') / sin(55°10') </span>
<span>x = 471.44 </span>
<span>x = 471 ft </span>
