Answer: Check if numbers are prime. Composite numbers prime factorization (decomposing, breaking numbers down to prime factors). Inscribe them as a product of prime factors, in exponential notation.
Option B
5 hundredths is not the way to express 0.50
<h3><u>Solution:</u></h3>
Given that Three of the choices are ways to express 0.50
To find: wrong option
Let us first write 0.50 in different ways
<h3><em><u>
To convert a Decimal to a Fraction follow these steps:
</u></em></h3>
Step 1: Write down the decimal divided by 1, like this: decimal 1.
Step 2: Multiply both top and bottom by 10 for every number after the decimal point. ...
Step 3: Simplify (or reduce) the fraction.

means 50 hundredths
<h3>Therefore option D is correct</h3>
On simplifying
we can write,

means one half
<h3>Therefore option A (one half) is correct</h3>
Similarly, \frac{5}{10} means 5 tenths
<h3>Therefore Option C is also correct</h3>
Thus the wrong option is B
<em><u>Justification:</u></em>
5 hundredths can be written as:

Therefore option B is wrong
parallel when a=2
perpendicular when a=-1/2
Answer:
2x= 40°
5x= 100°
Step-by-step explanation:
2x on opposite angle because it is an isosceles triangle
2x+ 2x+ 5x = 180° (angles of a triangle)
9x= 180
x= 180/9
x= 20°
Sub
2(20)= 40°
5(20)= 100°
