Answer:
Rational numbers, in arithmetic, is a number that can be represented as a fraction with integers e.g -15, 47, 3.14 and so on.

Answer:
<u>Story</u>
Jane is 1.7 m tall. She stands 250 m away from the base of the Eiffel tower and looks up at the top of the building. The angle of elevation from her eyeline to the top of the building is 45°.
<u>Question</u>
Calculate an estimate of the height of the building. Give your answer to the nearest meter.
<u>Calculation</u>
Label the sides of the triangle O, A and H (where O is the side opposite to the angle, A is the side adjacent to the angle and H is the hypotenuse).
In the triangle, the angle and side A is known, and O must be calculated.
Therefore, use the trig ratio tan(x) = O/A:
⇒ tan(40) = O/250
⇒ 250tan(40) = O
⇒ O = 209.7749078...
Assume Jane's eye-level is approximately 1.5 m above the ground.
Therefore, the Eiffel tower is approximately:
209.7749078... + 1.5 = 211.2749078.. meters tall
Rounding to the nearest meter ⇒ 211 m
<span>Answer: Option (C) Never
Explanation:
Irrational numbers are the numbers that CANNOT be written as the fraction of integers. On the other hand, integers can ALWAYS be written as a fraction.
For Example:
10 (an integer) can be written in a fraction forms as: 10/1, 100/10 etc.
Hence all integers are NEVER irrational numbers.
Information:
Few might say that although Pi (3.141592653...) is an irrational number, but we can write it as 22/7. 22/7 is mere approximation we use for the ease of calculations, NOT an accurate fraction for Pi.</span>
The probability of a sporting event being cancelled due to rain or lightning is 6/25
<h3>What is Probability?</h3>
This is the likelihood or chance that an event will occur.
Probability = Expected/Total
Given the following
- Pr(rain) = 3/5
- Pr (lightening) = 2/5
The probability of a sporting event being canceled due to rain or lightning = 3/5 * 2/5
The probability of a sporting event being canceled due to rain or lightning = 6/25
Hence the probability of a sporting event being cancelled due to rain or lightning is 6/25
