Question

without actually dividing find which of the following are terminting decimals 3/25 11/18 13/20 41/42​

Answer 1

Answer:

A body is projected with initial velocity of 40 m/s and at an angle of 30°with the horizontal. Calculate (i) time of flight and (i i) horizontal range of projectile.(assume g= 10 m/s²)Use the quadratic formula to solve the equation. Give exact answers: 2x^2 -1 = 6x. The choices are: a) -3 + square root(7)/2, -3 - square root(7)/2 b) 3 + square root(11)/2, 3 - square root(11)/2 c) 3 + square root(7)/2, 3 - square root(7)/2 d) -3 + square 

Answer 2

Step-by-step explanation:

I) 3/25

25 = 5×5

Since denominator has the factor as 5 it is a terminating decimal

II) 11/18

18 = 2×3×3

Since the denominator don't only have factor as 5 or 2 or both it is a non-terminating reccuring decimal

III) 13/20

20 = 2×2×5

Since the denominator have factor both 2 and 5 it is a terminating decimal

IV) 41/42

42 = 2×3×7

Since the denominator don't only have factor as 5 or 2 or both it is a non-terminating reccuring decimal
