0.45 as a fraction is
45/100 and in simplest form it is
9/20.
Answer:
Step-by-step explanation:
Interest earned during the rest of 2 years and 6 months
40 + 40 + 40 = 120
he will be getting 1000 at the time of maturity ie after 2.5 years .
Total receipt = 1000 + 120 = 1120
investment made = 820
total receipt earned = 1120
profit made = 300
time = 2.5 years
profit = investment x rate of intt x time / 100
300 = 820 x r x 2.5 / 100 where r is rate of interest
r = 30000 / 820 x 2.5
= 14.63 % .

The formula you need to know is that the side opposite of the 30° angle is always half the hypotheneus. For example in question 2 X should be 6 since 3 is opposite side of the angle 30°. In a 45 45 90 triangle, it is important to know that the straight sides are always the same length (since they are the same angle). For example in question 9, v is also 9√2.
When you have two sides, you can figure out the third side with a² + b² = c² since they are all right triangles. Good luck
