just use what you know about this stuff
(a+36d)/(a+20d) = (a+55d)/(a+36d)
(a+36d)^2 = (a+55d)(a+20d)
a^2+72ad+1296d^2 = a^2+75ad+1100d^2
3ad = 196d^2
3a = 196d
That is, for any value of n,
a=196n
d=3n
So, there is no unique solution.
If n=1, then a=196 and d=3. The terms are
196+20*3 = 256
196+36*3 = 304
196+55*3 = 361
304/256 = 361/304
You can easily verify that it works for any value of n.
The answer is 51
8 1/2x6=51
Answer:
The constant of variation is 5
Step-by-step explanation:
We know direct variation is of the form
y = kx
We know y =25 and x=5
25 = k*5
Divide each side by 5
25/5 = 5k/5
5 = k
Answer:
The time at which they will all meet at a place together is 350 minutes
Step-by-step explanation:
The time it takes Faiza to cycle the park = 60 seconds
The time it takes Krish to cycle the park = 14 seconds
The time it takes Joe to cycle the park = 25 seconds
Therefore, the time they will all meet at a place together is given by their Lowest Common Multiple as follows;
LCM = 60 × 14 × 25 = 21,000 seconds
Therefore, the time at which they will all meet at a place together in minutes = 21000 seconds/(60)×minute/second = 350 minutes
