Irrational numbers are numbers that have decimals and the decimals randomly keep going on. Remember, a repeating decimal is not necessarily an irrational number. (pi, sqrt(2), etc)
An integer is a whole number. (1, 2, 3, 4, etc) it could also be negative.

An irrational number is any real number that cannot be expressed as a ratio a/b, where a and b are integers, with b non-zero, and is therefore not a rational number. <span>An integer is any real whole number. </span><span>Basically, this means that an irrational number cannot be represented as a simple fraction.</span>

A standard clock has a 1-cm hour hand and a 2-cm minute hand. At 12 pm, they are both pointing in the same direction and the dis
Levart [38]

Answer:

The distance between the hands is √(3)cm ≈ 1.73cm.

Step-by-step explanation:

In a standard clock, the angle between every number is 30°, therefore the angle between 12 and 2 will be 30° x 2 = 60°.

Looking at the diagram, to find c we can make use of our cosine formula

c² = a² + b² –2abCos(C°)

a = 2, b = 1 and C° = 60°

Therefore we have:

c² = 2² + 1² –2 x 2 x 1 x cos(60°) =

c² = 4 + 1 – 4 x 0.5 =

c² = 5 – 2 =

c² = 3

c = √(3) ≈ 1.73

Therefore, the distance between the hands is √(3)cm ≈ 1.73cm.

Lincoln Middle School has a student body of 5 ^5 students. Each class has approximately 5 ^2 students. How many classes does the
Tamiku [17]

There are 5^5 students on the school and 5^2 students per class.


So, think:


1 class ----------- 5^2 students

x classes ---------- 5^5 students


Multiply:


1 . 5^5 = x . 5^2

So,


5^5 = x.5^2

x = \frac{5^5}{5^2}

x = 5^{5-2}

x = 5^3

x = 125


There are 125 classes.
