Answer:
y = 110/3 or 36.6 (the 6 is infinite so make a line over it when entering the answer)
Answer:
14^3/100 i think im not 100% sure so if its wrong dont get mad
Step-by-step explanation:
45 hours.
80 - 70= 10, and 450/10 is 45.
to justify, you can do 70x45= 3,150, and 80x45= (3,600 - 3,150= 450)
Given:
The sequence is:
2, 6, 10, 15,...
To find:
Whether the given sequence is Arithmetic, Geometric, Neither.
Solution:
We have,
2, 6, 10, 15,...
Different between consecutive terms are:
Since 
, therefore the given sequence has no common difference. It means it is not an arithmetic sequence.
Ratio of consecutive terms are:
Since 
, therefore the given sequence has no common ratio. It means it is not a geometric sequence.
Since the given sequence is neither arithmetic nor geometric, therefore the correct option is C.
Answer:
40 years and 20 years
Step-by-step explanation:
Let the father's age be y and son's age x
Father is currently twice son's age i.e 2x
16 years ago, the son was (x-16) years old
the father was (y-16) or (2x-16) years old.........(i)
The second sentence states that the father was 6 times his sons age 16 years ago i.e 6(x-16)yrs old.............(ii)
Equating (i) to (II) gives 2x-16 = 6(x-16)
2x-16 = 6x-96
Collecting like terms, 96-16 = 6x-2x, 80 = 4x, x = 20
Therefore, son's age is 20years and fathers age is twice son's age = 40 years
